Response Of Soybeans To Available Potassium In Three Kentucky Soils, John H. Grove, William O. Thom, Lloyd W. Murdock, James H. Herbek

Agronomy Notes

Soybeans are produced in nearly all of Kentucky's soil physiographic regions. Soybean response to potassium (K) fertilization and soil test Kvaries with soil type and location. This variation may be associated with the wide range in soil chemical and mineralogical properties among the different regions. Of particular interest are differences in that level of soil test Kat which no further yield response to K fertilizer application would be expected. The main objective of this work was to evaluate the soil K-soybean response relationship on three different field sites where soybean yields were increased by fertilizer K. Several measures of soil …

Soil Test Potassium As An Indicator Of Tobacco Response To Band Application Of Fertilizer, J. L. Sims, Kenneth L. Wells, E. C. Schwamberger

Agronomy Notes

During the past 10 years, several studies have been conducted at Lexington on the University of Kentucky Experiment Farm to compare the effect of banding fertilizer 10 to 12 inches to each side of the row with preplant broadcast applications on growth and yield of burley tobacco. Generally, banding most of the nitrogen and potassium has led to fewer problems with salt and manganese toxicity and to improved growth during the early season. However, as compared to broadcast application, banding has had varying effects on cured leaf yields. In 'some experiments banding resulted in higher yields, in other experiments in …

Cc90-342 Soil Compaction...Fact And Fiction: Common Questions And Their Answers, Alice J. Jones, Robert D. Grisso, Charles A. Shapiro

University of Nebraska-Lincoln Extension: Historical Materials

What causes soil compaction? Compaction occurs when soil particles move closer together because of external forces exerted by humans, animals, equipment and water droplets. It can be found on the soil surface and at almost any depth. Compacting soils leads to conditions that are less than optimum for crop growth, soil water management and efficient use of agricultural chemicals.

G90-945 A Gardener's Guide For Soil And Nutrient Management In Growing Vegetables, E.J. Penas, Dale T. Lindgren

University of Nebraska-Lincoln Extension: Historical Materials

How to manage soil and nutrients when growing vegetables is discussed here, as is soil testing, soil pH, organic matter, and the use of commercial fertilizers.

Using fertilizers as nutrient sources in growing vegetables is one cultural practice that can improve production if done correctly. This means using the right fertilizer material, applying it at the correct rate and time, and using the proper method of application.

Fertilizer needs for vegetables depend on the kind of vegetable grown, chemical properties of the soil, previous cropping history, and adequate water for plant growth. Guidelines here are based on soil chemical properties …
