ORGANIC AMENDMENT EFFECTS ON PHYSICAL AND CHEMICAL-PROPERTIES OF A SANDY SOIL

Field studies were established on an Evesboro loamy sand soil (mesic, coated Typic Quartzipsamment, 97% sand) to compare the effects of sewage-sludge compost, beef manure, and fertilizer amendments on soil properties. Compost application rates were based on the assumption that material would be applied either only once or annually. Application rates ranged from those that were too low to excessively high rates. Soil properties such as strength (penetrometer resistance), bulk density, water retention, pH, surface area, total N and P contents, and organic matter were evaluated for 5 yr. -from Author
