How To Benchmark Crop Macro and Micronutrient Status

The effectiveness of soil and tissue tests depends on the crop, field conditions and the nutrient in question, and no-tillers should back up the results with scouting and on-farm strip trials.
Peter Kyveryga says he's been hearing more and more discussions among farmers about nutrient deficiencies in corn and soybeans during the growing season.

Adding winter wheat, livestock and cover crops helped Paul Ackley overcome his no-till plateau, simplify his planter and build more productive soils.
I never was one to like tillage. It just didn’t make sense. You would go through and make a perfect seedbed to plant into and then, without fail, you couldn’t get back in the field with the planter before it would rain. Then you would have to start all over again.

Phosphorus, Potassium Fertilizer Recommendations For High-Yielding Soybeans

The keys to maximizing the economic returns from phosphorus (P) and potassium (K) fertilizer applications are a comprehensive soil testing program and maintaining P and K soil test levels above their respective critical levels. The critical level for a given nutrient is the soil test level at which 95% to 97% of the crop’s yield potential will be reached with no additional inputs of the nutrient.

Still Time To Soil Test Hay Fields

Soil test samples can be pulled any time of the year when the ground is not frozen. Various experts advise to try to soil test at the same season of the year to have a more accurate trend line when you compare fertility levels over long periods of time.

Tips For Getting More From Your ‘P And K’

Building healthier no-till soils, frequent soil testing and other readily available products and practices can help no-tillers stretch their fertility dollars further, regardless of their application system.
The price tag for phosphorus and potassium is way too high for no-tillers to allow nutrients to tie up, float away or just plain not do their job effectively.

Study Challenges Soil Testing For K, Value Of KCl

In the chemical age of agriculture that began in the 1960s, potassium chloride (KCl), the common salt often referred to as potash, is widely used as a major fertilizer in the Corn Belt without regard to the huge soil reserves that were once recognized for their fundamental importance to soil fertility.
