Nutrient Losses From Conventional And No-Till Cornfields, Robert L. Blevins, Wilbur Frye

Soil Science News and Views

Farmers must be concerned about both the monetary loss and the threat of groundwater and surface water pollution associated with the loss of plant nutrients from their fields. There is also an increasing public concern about pollution and the role of agriculture in nonpoint-source pollution. Movement of water over the surface of the soil as well as through the soil profile increases the potential for loss of water-soluble nutrients, especially nitrates.

Depth Profiles And Soil Textures Of The Vernal Pools Of The Santa Rosa Plateau Preserve, Riverside County, California, Ralph Charles Workman Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this project was to study the edaphic and topographic characteristics of the 13 vernal pools on the Santa Rosa Plateau Preserve, thus documenting the role soil texture plays in vernal pool formation.

Several field and laboratory procedures were used to demonstrate that there is a higher percentage of clay present within vernal pools than in soils outside the margin of the pools, for 11 out of the 13 pools. Statistical tests showed that the percentage of clay was highly significant within the center soil of the pool as compared to the soil outside the margin of the …

Potassium Mineralogy Of Kentucky Soils, Anastasios D. Karathanasis

Soil Science News and Views

Feldspars and mica minerals are the two primary natural sources of potassium for most agricultural soils in Kentucky. Potassium feldspars are common mineral constituents of loess deposits in western Kentucky. Mica minerals, although dominant in shales, are also found in variable quantities in siltstone, sandstone and limestone parent materials of soils in the other regions of Kentucky. Because most of the soils in the western Coalfields and western Pennyroyal, and to a lesser extent in eastern Pennyroyal and Bluegrass, are covered by a loess cap of variable thickness, their surface mineralogy has been influenced by the feldspar-rich mineralogy of the …

Using Residual Soil Fertility Effectively, Grant W. Thomas

Soil Science News and Views

During the past 30 years, the use of commercial fertilizer in Kentucky has resulted in increases in the levels of phosphorus and potassium in soils. As might be expected, the soil test levels are higher with tobacco than with any other crop. but all soils for all crops show increases in fertility levels. Comparisons between 1975 and 1985 (the latest year available) show the proportion of samples sent to the University of Kentucky that are medium or high in soil test phosphorus has increased considerably. Even more striking is the decrease in very low values of phosphorus.

Sludge For Agricultural Land, William O. Thom

Soil Science News and Views

Sludge is a product of municipal wastewater treatment with characteristics dependent on both the initial wastewater composition and the subsequent treatment processes used. The sludge composition influences the options that are available its use. For decades, the objective has been disposal. generally meaning that it was buried in a landfill or incinerated. Efforts in recent years have been directed toward application of sludge to agricultural land. Farmers should be aware of several potential problems when deciding whether or not to use sludge for such purposes.

Soil Microbes And Biotechnology, M. Scott Smith

Soil Science News and Views

There is nothing new about attempts to develop and market microbial products for crop or soil improvement. Several types of microbes have been sold for a variety of agronomic purposes for many years. With the important exception of rhizobial inoculants. these have been generally unsuccessful. Recently however. the scientific revolution in genetics and molecular biology, the need for low cost agronomic inputs. and widespread concern for environmental safety have tremendously stimulated research and commercial activity on microbial products. Claims that cheap, effective microbial inoculants can be developed for pest control, detoxifying pollutants, providing plant nutrients and improving soils have been …

Seedbed Preparation For Fall Seeded Alfalfa, Kenneth L. Wells, J. Kenneth Evans

Soil Science News and Views

With the increased interest developed during the past few years on production of alfalfa hay for cash sales, the acreage seeded each year has increased • And. although UK forage specialists prefer spring seeding of alfalfa to fall seeding. some growers will and should opt for fall seeding. This is particularly true on fields which have a history of legumes and/or are contaminated with Johnsongrass. Those who do so should begin planning now to have the seedbed prepared for planting by mid-August to mid-September.
