Master Tree Farmer Program
A Broadcast Satellite Program For Forest Landowners


We have a very unique opportunity to participate in the Master Tree Farmer 2001 Program. This program was first developed in 1999 to provide private, non-industrial forest landowners in the Southern Region with an opportunity to further their knowledge of natural resource management on their lands.

If there is interest, the Master Tree Farmer 2001 satellite broadcast will be held every Tuesday evening, from February 6 to March 20, 2001, at the Marion County University of Missouri Extension Center in Palmyra.

The course will introduce forest landowners to stewardship considerations, best management practices for protecting the environment and enhancing wildlife habitats, planning to meet landowner objectives as well as services and assistance available for Missouri landowners in managing their forest land.

Local professional instructors and presenters will include staff from the MU School of Natural Resources, the Missouri Department of Conservation, the Natural Resources Conservation Service, University of Missouri Extension, and the Missouri Tree Farm Committee.

Topics will include Forestry as an Investment (Estate Planning, Taxation, and Basic Forestry Finance), Managing for Pine (Natural and Artificial) and Agroforestry, Managing for Hardwoods (uplands and bottomlands), Timber Marketing, Security and Harvesting, Wildlife Management (Game and Non-game), and Forestry Services and Programs for the Missouri Landowner.

This satellite downlink program will be held at the Marion County Extension office if there is sufficient interest. If you would like to attend this series of courses, please contact the Marion County Extension office at (573) 769-2177, or the Ralls County Extension office at (573) 985-3911.

The Soybean Cyst Nematode

The soybean cyst nematode (SCN) is a microscopic roundworm which can cause severe yield losses in soybeans. This nematode damages soybeans by feeding on plant roots, in the process robbing the plants of nutrients and providing a site of entry for root-rotting fungi. The severity of symptoms and yield losses are dependent on several factors, including the number of nematodes present in the field at planting, the soybean variety, soil texture, fertility, soil moisture, and tillage practices. Many fields show no obvious above-ground symptoms, but do have some yield reduction. Once soybean cyst nematode has become established in a field, it rarely can be eradicated. The first step in soybean cyst nematode management is to determine which fields have soybean cyst nematode present and how many nematodes are there. Now is the ideal time to begin a field survey for the presence of SCN; at harvest, SCN populations at their highest.

Symptoms
Soybean cyst nematode damage is often confused with other problems, such as nutrient deficiencies, herbicide injury, soil compaction, or diseases. In areas with high infestations of SCN, circular to oval patches of stunted, yellow plants may be noticed in July or August. Presence of SCN is difficult to determine visually, as there may be no other above-ground symptoms other than reduced yield. Often, there is no symptom of SCN other than reduced yield.

Life Cycle
There are three stages of the SCN life cycle: egg, juvenile, and adult. Under favorable conditions, the life cycle can be completed in 24 to 30 days. The infective stage, the juvenile hatches from an egg and searches for a soybean root to infect. The juveniles can move only short distances in the soil, and die quickly if no soybean root is found. If a root is found and penetrated, the nematode feeds on the vascular tissue of the plant. Juveniles then molt prior to becoming an adult. If the molting nematode becomes male, it leaves the root for the soil and most likely causes no further plant damage. If the juvenile becomes female, it will swell within the root to a white, lemon-shaped structure. This "white" female causes the primary plant damage caused by SCN. As the female ages, the cyst she forms yellows and eventually browns as the nematode dies. The brown cyst contains from 150 to 500 eggs, and protects the eggs from the soil environment. In general, 50% of the eggs produced hatch each year. Because of this, the population may drop substantially after several years if no host plants are present. Cysts on soybean roots are visible to the naked eye, and are much smaller than the nitrogen-fixing nodules.

SCN Races
Sixteen SCN races exist, these refer to ability of a SCN to reproduce on soybean varieties with specific genes for SCN resistance. Limited sources of SCN resistance exist in soybean varieties; for this reason, it is important to rotate the source of resistance to delay the emergence of a resistant SCN population. Repeated planting of the same resistant variety will lead to the development of a SCN race which is adapted to that source of resistance.

Hosts
Alsike clover, bird’s-foot trefoil, crimson clover, lespedeza, and sweet clover are all crop hosts of SCN. Rotation with crops other than these will allow for the decrease of SCN numbers within a field. Alfalfa, barley, corn, forage grasses, oats, red clover, sorghum, and wheat are non-host crops, they cannot be used as a food source by SCN and reproduction of SCN on these species is impossible.

Managing SCN
The first step in managing SCN is to identify the fields where SCN is present and monitor their populations. The best time to sample fields is in the fall, following harvest. Specific sampling procedures for SCN have been developed; contact your local extension center for details.

Rotation with non-host crops (corn, sorghum, small grains, alfalfa) is an integral part of SCN management. If possible, sources of genetic resistance in soybean varieties should be rotated as well, as this will prevent a race shift. Plants should be maintained in as stress-free an environment as possible. Damage from SCN is amplified when the crop is under stress from weed competition, nutrient deficiencies, drought, and insect and disease pressure. Care should be taken to avoid introducing SCN to non-infested fields. This is best done by working uninfested fields before infested fields. Nematicides for SCN control are available, although resistant varieties are a more reliable and cost-effective means of control.

2000 Crop Performance Books

The 2000 Winter Wheat Missouri Crop Performance books are now available at local University Outreach & Extension Centers. Soft red winter wheat yields at the Novelty, Missouri location ranged from 73.9 to 90.9 bushels per acre. These results are also available on the Missouri Agricultural Electronic Bulletin Board at Crop Performance books for soybean and corn have a tentative release date of October 23. If you are interested in obtaining a copies of any of these crop performance results, please contact your local University Outreach & Extension center.

Show-Me-Select Heifers

The December 8, Show-Me-Select Bred Heifer Sale will be the fourth sale to be held at Palmyra. Our area was one of the two areas in the state to start this replacement heifer program in 1997. The program is proving to be beneficial to both the cooperating herds and to buyers of the heifers.

The thirty-eight buyers at the Northeast Show-Me-Select Sale were surveyed to see how they got along with the heifers they purchased. Thirty-six of the 38 buyers returned their surveys. This represented over 500 head of Show-Me-Select heifers that calved in the spring of 2000.

Out of the 512 head only 51 head were assisted in any way at birth. That is only ten percent. The national average for first calf heifers being assisted at birth is about 22 percent. Of the 51 head, ten head were assisted due to abnormal position of the calf, which is something we can't control. So, only eight percent were assisted for reasons we can control.

Only four percent of the calves were lost at birth. Again, the national average is between 8-10 percent for first calf heifers. Seven head of the heifers aborted prior to calving time. So, 95 percent of the Show-Me-Select heifers had a live calf.

Another aspect of the Show-Me-Select heifer sales that many buyers like is the fact we give them estimated, projected calving dates. One thing we were really pleased with this year was that over 90 percent of the heifers calved within two weeks of their projected calving dates.

These results were real similar to results from the first two Show-Me-Select sales held at Palmyra, Mo. The three year average for number assisted at birth is 9.5 percent and number born dead is 3.8 percent. This represents over 1000 head of heifers sold in the three years we've been having a sale at Palmyra.

The following was taken from Ron Plain’s Weekly Swine Economics Report.

The hog-corn ratio (the price per hundredweight of live hogs divided by the price of a bushel of corn) has long been used as a quick indicator of the profitability of hog production. It is also a pretty good predictor of future changes in sow numbers. When the hog corn ratio (HCR) is high, hog production is almost always profitable. This inevitably results in an expansion in sow numbers. A low HCR usually indicates financial losses for hog producers which leads to a cut back in the breeding herd.

For recent hog cycles, an HCR above 20 has signaled a coming expansion and an HCR consistently below 20 has signaled a forthcoming cutback in hog numbers. It is usually about five quarters after the HCR goes above (below) 20 before hog slaughter goes above (below) year earlier levels.

Hog prices have spent much of this year in the $40s. Despite these somewhat mediocre prices, the hog corn ratio has been above 20 since mid March. The reason for the high HCR is, of course, low corn prices. Each of the last four years has produced a 9+ billion bushel corn crop and this year's crop is forecast to be a record 10.36 billion bushels. Needless to say, corn prices are very low. For the six months ending in September, the HCR has averaged above 26, the highest average for this time of year since 1987.

With the traditional five quarter lag, one shouldn't expect hog slaughter to go above year levels until the third quarter of 2001, five quarters after the HCR went above 20. USDA's September hogs and pigs report indicates hog slaughter could go above year earlier levels sometime during the first quarter of 2001. My calculations, based upon gilt and sow slaughter, indicate barrow and gilt slaughter is likely to go above year earlier levels at the start of 2001.

Why a quicker than average response to a high HCR? My explanation is that the hog industry currently has a bias towards growth. Pork production per sow has been increasing by 3% per year recently. This is double the historic rate. Unlike pasture systems, modern hog facilities are too expensive to run half full. Finally, there are a lot of producers who feel they need to be bigger to remain competitive.

Hopefully, historic relationships will win out again and hog slaughter will stay below year ago levels until the fall of 2001. But, don't be surprised if we are close to the end of the current down phase of the hog cycle.

Whole Soybeans & Beef Cows

Some of my co-workers have run some field trials the past two winters on feeding whole soybeans to beef cows. The idea is to see if unsaturated fatty acids (vegetable oils) will enhance the reproductive efficiency of the beef cow. Whole, non-processed soybeans contain 18% fat and 38% protein.

They have fed 3.5 pounds of whole soybeans per head for 30 to 45 days prior to calving. Yes - prior to calving not breeding!! The control cows were fed a comparable ration of corn gluten and soybean meal for the same period. After calving the supplemental feeding was stopped.

The results were that both first service conception and overall pregnancy rate was increased by feeding the whole soybeans. On the average of three trials the first service conception rate was 17% higher for the soybean fed cows and overall final pregnancy rate was 6% higher.

Another way of looking at it is if you had 100 cows you would have 17 additional calves that would be 21 days older at weaning and you would have 6 more total calves at weaning. I guess I would not expect these results in all cases, but with the present price of soybeans, it may be worth considering.

FARM MANAGEMENT NOTES

Farm Losses or Hobby Losses: Farmers and Business Owners Must Plan Ahead

Hobby loss is an often misunderstood area of taxation, causing worry to the taxpayer involved in a business. Congress sets rules which state that in order to deduct expenses in excess of income for a given venture, you must be engaged in that venture for profit. Profit is defined as income greater than expenses, where expenses include depreciation of capital assets. The rules on hobby loss provide an objective standard to determine whether a taxpayer has a legitimate business operation or is attempting to generate tax losses to offset other income. If there is no intent to make a profit, the IRS assumes the activity is a hobby and will disallow deduction in excess of income. The general test to measure profit motive is whether the activity has generated a profit in any three out of five consecutive tax years. If the activity deals with breeding, training, showing, or racing horses, the test is any two out of seven years. While many taxpayers are aware of this general test, it is usually as much information as the average taxpayer knows. For the struggling business owner whose business venture is not showing a profit, it is often a concern that the IRS will follow the general test and disallow all deductions. However, there is more information available to help the taxpayer in this situation.

The "hobby loss" profitability test of three out of five years (or two out of seven for horse breeders) does not determine whether a business will be considered a hobby by the IRS. This test only allows the IRS to look at the business in more detail. Until the test of failing to show a profit for the stated number of years is met, the IRS cannot question the profit motive. Once the business has to show a profit in three out of five years (or two out of seven for horse breeders), the IRS can look at the business. This does not automatically mean they will, only that they can. In addition, the test does not automatically determine whether a business should be considered a hobby, but rather that the IRS can examine it in more detail.

The actual decision of whether a business has been operated with a profit motive is based on all facts and circumstances. There are nine factors set forth in the IRS regulations to be used as guidelines – no one factor or group of factors will determine the outcome. It is a subjective judgement call where all facts are taken into account. However, the taxpayer can protect himself or herself by being aware of these nine factors and using them as guidelines. Most importantly, the taxpayer can further be protected by keeping good records.

1. If it looks like a duck and sounds like a duck, it is a duck. Is the activity carried on in a business like manner? If the taxpayer keeps business like books and records, changes methods of operation that are not working, tries to use new techniques of profit-making ventures to increase efficiency and profitability, or even abandons a business venture that is going nowhere, the profit motive may be indicated.

2. Can you take advice? What is the expertise of the taxpayer or his or her advisors? The taxpayer should be able to show that he or she has studied the accepted practices of the venture engaged in and/or has sought advice from experts in the field. In other words, he or she has read books, taken classes, paid advisors, and taken their advice. If the taxpayer has gotten advice and information and has operated in a completely different manner, he or she should be prepared to show that an attempt has been made to develop new practices which could result in profit.

3. Are you spending time here? How much time and effort are being expended by the taxpayer in this business? If the taxpayer is spending significant personal time and effort on the activity, it can indicate a profit motive. Employing competent persons to run the activity for the taxpayer may also indicate a profit motive.

4. Is anything here worth money? Are the assets expected to appreciate? Overall profit could be reasonably expected from an increase in land value, cattle, or other assets, even if operations of the business are not showing a current profit.

5. Have you done this before? Has the taxpayer been successful in carrying on similar activities for a profit? If the taxpayer has carried on similar activities in the past and turned them from unprofitable to profitable, a profit motive could be assumed.

6. What’s been happening here? What is the history of income or loss? Are losses mainly a start-up situation, or have they been sustained beyond a reasonable length of time? If there have been unforseen circumstances beyond the taxpayer’s control, such as drought, fire, theft, war, depressed market conditions, etc., the reasonable length of time for loss could be extended. Again, good records would help support this type of claim.

7. Have you made any money? What profits, if any, have been earned? The occasional small profit from a venture offset by persistent losses would probably indicate there is no profit motive. A solid profit, though infrequent, or a reasonable opportunity to achieve an eventual profit might support the taxpayer’s profit motive.

8. Are you making money doing anything else? What is the financial status of the taxpayer? If there is no substantial income from other sources, it is a good bet the activity is meant to generate a profit. However, the presence of other income, especially during the start-up period of a venture, shows good planning and would not negate the profit motive.

9. Are you having fun? The presence of personal pleasure in an activity has often been used by the IRS to claim an activity as a hobby. However, the other factors mentioned in this article are also taken into consideration by the courts. The fact that a person enjoys a business in not sufficient to disallow the profit-making motive.

If you have taken a class related to your business, consulted with an accountant or business expert, or bought a book, keep the receipts. If you have taken advice and changed a method of operation to improve efficiency, write it down. If there has been a flood, drought, or disease in the area affecting your business profits, write it down, cut out the news articles, keep records. Record your hours, record your mileage, keep your receipts, and hope you make a profit next year.

This information is provided to educate taxpayers about the income tax consequences of hobby losses. If you need more specific information, or feel your farm or business operation is in danger of being declared a hobby by the IRS, contact your income tax preparer, or the University of Missouri Extension office in your county. Your University of Missouri Extension office can get you in touch with the professional you need.

FARM MANAGEMENT NOTES
Dr. Don Smith


 The Meaning of "Precision Agriculture"

During the past five years technology has advanced to the point of tools capable of making more accurate farm management decisions and controlling their implementation. Because of this, "Precision Agriculture" is often discussed or thought of in terms of the technologies that make more precise decisions, control and implementation possible. However, it is very much possible to adopt the concept of "Precision Agriculture" without all of the technology bells and whistles.

One dictionary defines "precise" as "Exact, as in performance, execution, or amount: accurate or correct. A definition of "precision" is given as "the quality or state of being precise : EXACTNESS" and "the degree of refinement with which an operation is performed or a measurement stated: ACCURACY."

There are several components to "precision farming." For example, a few critical factors in the Variable Rate Application of fertilizers would be:

Choice of size of the unit or grid to which the procedure will be applied, soil tested, and so on. This might be 10 acres, 5 acres, 2.5 acres, 1 acre, or less.

Second are the limitations (or smallness of units) and accuracy of each instrument or procedures used to do the measurements (such as a tape measure, wheel, or chain) or analysis (such as a soil test).

Next is the level of skill and conscientiousness of each person in operating various devices, or performing procedures, and accurately recording their results.

Fourth, is the skill and accuracy of the individual in utilizing all relevant information, such as economics, crop yield response curves, environmental impact, etc., to make optimum application recommendations.

Next would be the uniformity and accuracy of the plant food mixture.

The final factors would be the limitations of accuracy of the controlling mechanisms and skills of the machinery operator in applying the fertilizer.

It is important to realize that in "Precision Agriculture", "Precise" and "Precision" are very much relative terms. For example, when a person who has typically used a "rules of thumb" or arbitrary rates of application begins soil testing and using the recommendations on individual fields to apply fertilizers, he has become more precise. If that person breaks application areas into smaller sub-field units of 40, 20, or 10 acres, etc. they are even more precise and using one component of Precision Farming. The ultimate step would be to utilize yield response curves, value per unit of crop, costs of fertilizers, operator/landlord shares of costs and yield, and environmental affects to arrive at the optimum rates to apply at the smallest manageable field area.

Another point is the changes in accuracy of measurement. Pesticide residuals, which once could only be measured in Parts Per Thousand, can now be measured in Parts Per Million or less. Similar developments are occurring in GPS and Variable Rate equipment controllers.

Good farm record systems for collecting and analyzing production and economic information should be the first priority in making "Precision Decisions." The tools and skills needed to implement Variable Rate Applications, Yield Monitors, Global Positioning, etc. associated with Precision Farming may have a bit steeper learning curve but new developments are making this less difficult.

Individuals should be in the information gathering mode at every opportunity to become aware of these developments and decide when to adopt selected practices. One of these learning opportunities is a "Farm Technology Meeting" scheduled for 6:30 p.m. on Thursday February 21st at the Kahoka High School Vo-Ag Department. At this program area farmers can have a close-up look at farm machinery and other technology on display and listen to experts speak on benefits and limitations of the various tools. This meeting is organized by the Clark County Farm Bureau and supported by Farm Machinery Dealers, Clark County High School Vo-Ag Department, Clark County University of Missouri Extension, and others.

For more information on this or other subjects visit the University Extension Center in your county, call me, Dr. Don Smith, at (660) 727-3339, or visit the Clark County University of Missouri Extension Internet Web Site at http://outreach.missouri.edu/clark/ for publications online. University of Missouri Extension programs and services are open to all and most are free or at a nominal charge.
