The Electronic Side
of Soil Testing

Each county extension center is a drop-off point for mailing horticultural and agricultural soil samples. UMC Guides are available which provide further information: G9110, "How to get a good soil sample" and G9112, "Interpreting Missouri Soil Test Reports". Still others have information on the value of major nutrients like phosphorus, potassium and lime.

A new feature is the electronic delivery of soils test results via the Internet through the nutrient-testing laboratory web page at the University of Missouri. Electronic retrieval can speed the turn around on soil tests from the laboratory. Soil test results are confidential, password protected and accessible only through the extension centers. Clients may contact their extension agronomy specialist to request access to the electronic recommendations. This cuts the time for new recommendations from days to minutes.

Annual Snake Oil Alert



It is time for the annual snake oil alert regarding miracle products and pesticides that may not really crack up to be worth their price. Often high-pressure sales personnel call on farmers in hopes of selling products. Usually the pesticides are registered for use with the Missouri Dept. of Agriculture. Typically they are nothing more than a diluted version of some common product or products. Be sure to inquire about the active ingredients and their concentrations when approached by these marketers.

Remember the old rule: if it is too good to be true, then it probably is.

Plant Tissue Analysis -- A Useful Diagnostic Tool to Determine the Health of Plants

Is your fertility program meeting the crops nutritional needs? A soil test indicates a soil’s likely nutrient supplying capacity. However, environmental conditions and soil factors such as compaction affect the actual supply of nutrients available to a plant – this is often more or less than that predicted by a soil test. Plant tissue analysis (plant analysis) is a diagnostic tool that measures the level of specific nutrients in a plant. Plant analysis may be used to determine the actual level of nutrients taken up by a crop versus those predicted by a soil test.

The plant nutrient concentrations are then compared to standardized values for specific growth stages and plant parts.  Since plant nutrient concentrations change during a growing season, it is imperative that sampling follows standardized procedures for growth stage and the plant part. UMC Guide G9131 Sampling Plant Tissue and Soil for Analysis provides instruction for proper collection, care and shipping plant samples for a variety of crops.

While symptoms for individual nutrient deficiencies are typically distinctive, a precise diagnosis may not be possible until a plant analysis is conducted. Nutrient deficiencies can be confirmed or rejected through the use of plant analysis.

When sick looking plants appear a paired sample technique may be used. Using this technique, paired samples are collected — one from sickly appearing plants and the other from nearby healthy plants. The healthy plant sample provides a comparison against which sick plants can be judged.

In addition, plant analysis can be used to determine non-visual crop nutrient deficiencies. Plants typically do not exhibit nutrient deficiency symptoms until severely deficient. Before such symptoms are exhibited, plants can suffer from “hidden hunger” in which yield-limiting nutrient uptake is being experienced.

The desired nutrient concentration requirements of crops are well established for their different growth stages. Thus a crop’s nutrient status can be monitored throughout the season. If the crop begins to approach a deficiency, then corrective measures can be taken.

Plant analysis need not be limited to the growing season. Some plant analyses can be considered post-mortem tests in which plant tissue from the crop residue or grain are analyzed to determine if a nutrient was deficient.

The University of Missouri Soil Testing Laboratory does plant analysis as one of its services. Forms can be obtained and samples submitted through local extension centers.  Click here to view the lab's web site.

The Soybean Aphid May Be Coming to a Field Near You

Last year a new soybean pest arrived in Missouri. Infestations were found from Michigan to Wisconsin and south into Kentucky and Tennessee and over to Missouri. The greatest numbers were found in Michigan and Illinois. No other aphid infests soybean. The coming season will tell us how successfully this new pest over-wintered.

The soybean aphid is a small, light green or yellow aphid, which can infest soybean as soon as the plants emerge. (Click here to view images of aphids.)  Currently, most of the information on soybean aphid comes from overseas research. China is a major source of this information and how much of it is directly applicable to Missouri is not known.

The earlier in the season an infestation starts, the more serious the potential for crop injury. Unfortunately, there are no economic thresholds established as yet for soybean aphid numbers nor are any pesticides labeled for the pest. Timely scouting of soybean fields should still be conducted to monitor the status of this pest. Suspected soybean aphid infestations should be reported to local extension centers. This information can then be used by the University of Missouri and the Missouri Department of Agriculture to determine the need for emergency aphid pesticide labeling.

Damage to the soybean plant occurs when aphids suck plant sap and the excess water and carbohydrates (sugars) are expelled as a material called "honey dew" (a very descriptive name). Fortunately, they do not inject a toxin during feeding. When high numbers are on infested plants, the amount of honeydew is large enough to literally drip. Chinese researchers report this feeding can cause a 27 percent yield reduction and significant stunting. Last year, heavily infested fields in Michigan and Illinois were stunted. The leaves in these fields were wrinkled, cupped and had yellow margins.

Throughout the growing season, soybean aphids are all females and produce all live females young. This gives them the potential to build serious infestations quickly. Soybean aphids have a few hosts plants (soybean, buckthorn, tick clover "sticktights", and kudzu). At the end of the growing season, male aphids are produced, mating occurs and over-wintering eggs are laid on buckthorn.

Think about these points if an infestation is found on your farm:

If there are no signs of stress due to feeding or high numbers, there may be little benefit from treatment.

Inspect soybean aphid infested plants for natural enemies.

If you feel it is necessary to spray, obtain special use labeling, use a ground applicator and apply at least 27 gallons of carrier per acre.

Most of all, don’t panic if you find soybean aphids in your soybean fields.  Contact your local extension center.

Taxation Tidbits:  Gifting Provisions
The annual gifting exclusion provisions allow an individual to transfer $10,000 per donee (person receiving the gift) to as many donees per calendar year as an individual is willing and financially able to make without creating any transfer tax liability for them self or the donees. The annual gifting exclusion provision is arguably one of the estate planning provisions with the greatest punch. Additionally the marital deduction allows unlimited transfers of property between spouses without incurring any transfer tax liability. The following explores some of the pros and cons of these lifetime transfers as well as some strategies for your consideration.

Two major potential drawbacks of gifting are:

Forfeiture of income and control -- An important objective and goal for many people is to assure adequate income whether they live to 85 or 135. To qualify for the annual gifting provision, the transfer must be a gift of a present interest. Thus the donor can’t gift the asset, and keep the right to the income or enjoyment of the asset – that would be a gift of a future interest.

Asset basis -- Determination of basis between gifted property and property passed via an estate is another important consideration. The donee's basis in gifted property is the same as the donor's basis; while an heir's basis of property is the value reported in the calculation of the descendant's gross estate (generally, the fair market value at date of death). This difference in the recipient's income tax basis can result in substantial difference of income tax liability should the recipient sell the property.

Benefits of gifting:

Gifts up to the $10,000 annual exclusion amount are not considered taxable gifts – therefore they are not included in the calculation of your taxable estate. Thus, if you and your spouse have 3 married children, the two of you could annually gift $120,000 to your children and their spouses without incurring any gift tax liability. The clue for the above calculation is that you and your spouse can each utilize the annual gifting exclusion provision.

Business transfer:  gifting can be used as a means of facilitating the transfer of a family business to succeeding generations.

Personal gratification:  gifting during life allows the donor the opportunity of witnessing the donee's use and enjoyment of the gifted property.

Given the substantial benefits of gifting and the potential disadvantages, the following strategies might be appropriate:

Never give away property you can't afford to do without.

Careful consideration should be given to what property is to be gifted.

Gift property least likely to be sold by donees.

Gift property with the greatest potential for appreciation.

Gift property with a high basis relative to its fair market value.

If taxable gifts are made in an attempt to freeze the value of gifted assets and utilize the unified tax credit -- consider transferring the life interest to the children with the remainder interest to the grandchildren -- thus, preventing the property from being taxed in your children's estate -- yet giving them the right to the property's income for their lives. Be aware that the value assigned to the remainder interest gifted to the grandchildren is a gift of a future interest and will be subject to gift tax which can be offset by the unified tax credit.

Estate planning offers the opportunity for tremendous tax savings and the ability to draft a customized plan to meet your goals and objectives. However, to minimize the potential of costly litigation and disputes among the heirs, a professional estate planner should be involved in the drafting or at least a review of your plan.
