Molybdenum Nutrition Of Crops In Kentucky, J. L. Sims
Molybdenum Nutrition Of Crops In Kentucky, J. L. Sims
Soil Science News and Views
Molybdenum (Mo) is one of eight micronutrient elements required for the growth of plants. Research conducted in California nearly 40 years ago established its need for plant growth. Mo deficiencies have been reported throughout the world, especially on acid soils in the United States, Australia, and New Zealand. Generally, the Mo requirement of leguminous crops is greater than for non~legumes, but many non-leguminous field and vegetable crops have responded to additions of fertilizer Mo under severe deficiency conditions. Of all the nutrient elements required by plants for growth, Mo is needed in smallest amounts.
Use Of Magnesium (Mg) For Crop Production In Kentucky, John H. Grove
Use Of Magnesium (Mg) For Crop Production In Kentucky, John H. Grove
Soil Science News and Views
Magnesium (Mg) is an important element in the nutrition of plants and animals, although it has long been considered a "secondary" nutrient for plants. Nitrogen (N), phosphorus (P), and potassium (K) are "primary'' nutrients and are usually given the greatest consideration in crop fertility programs. However, as yield levels have risen, more attention has been directed towards Mg and other nutrient elements. Concern about hypomagnesemia (grass tetany) in ruminants (cattle, sheep) has led to particular concern about soil and plant Mg levels.
Soil Surveys In Kentucky, Harry Hudson Bailey
Soil Surveys In Kentucky, Harry Hudson Bailey
Soil Science News and Views
Fifty-four Kentucky counties have modern soil surveys (published 1959, or later) using the mapping and soil classification procedures of the National Cooperative Soil Survey. The cooperators in the program include the USDA-SCS, USDA-FS, Kentucky Department for Natural Resources and Environmental Protection and the Kentucky Agricultural Experiment Station.
The Status Of Sulfur Fertilization Of Crops In Kentucky, Lloyd W. Murdock
The Status Of Sulfur Fertilization Of Crops In Kentucky, Lloyd W. Murdock
Soil Science News and Views
Sulfur has long been recognized as being essential for the growth of plants and animals due to it being necessary for production of several amino acids. Although regarded as a "secondary" element, it is required by plants in fairly high amounts, very similar to that of phosphorus. Sulfur deficiency symptoms in plants are somewhat similar to those of nitrogen since an overall uniform pale-green leaf color develops. Sulfur deficiencies are often found in crops growing on sandy soils with low organic matter content.
Influence Of Soil Type On Nitrogen Fertilization Of Corn, Grant W. Thomas
Influence Of Soil Type On Nitrogen Fertilization Of Corn, Grant W. Thomas
Soil Science News and Views
In Kentucky, response of corn to nitrogen fertilizer is influenced strongly by soil characteristics. These soil properties are of both a permanent and temporary nature.
Water Relationships Of Kentucky Soils, Ronald E. Phillips, Grant W. Thomas
Water Relationships Of Kentucky Soils, Ronald E. Phillips, Grant W. Thomas
Soil Science News and Views
Plant water stress is the most limiting single factor in crop production in Kentucky. It almost always occurs sometime during July and/or August even though it's variability makes it hard to predict. Even though the 1979 growing season was an exception to this generalization the 1980 growing season was a vivid reminder of this fact especially in Western Kentucky.
