A Systems Approach to Conservation Tillage ISBN: 9781351070850
Soil properties change when farmers change from a system of agricultural production that includes moldboard plowing and numerous tillage operations, such as conventional tillage, to a reduced tillage system. Other tillage practices such as chisel plo

Brittle fracture of heterogeneous materials such as dry soil aggregates is not well understood. The flaws in such materials occur as voids across a wide range of length scales. As a result, failure is an inherently variable phenomenon that is best an

Naturally occurring riparian filter strips are widely recommended as a technique for removing chemicals from flow prior to entering a stream. Data on their effectiveness is sparse as is information on the partitioning of chemicals trapped by various

Measures of aggregate size and shape are needed in models to predict soil erosion, seed bed density, tensile strength, and solute diffusion. We hypothesized that size (i.e., equivalent cubic length L c = [l 1 l 2 /√2)(l 3 /√3)] 1/3 , where l 1 ,

Parameters are needed to quantify tillage-induced changes in soil structure. Our objective was to see if fractal parameters from ped mass- and number-size relations could be applied to quantify such changes. Soil from long-term conventional (moldboar

A more sustainable agroecosystem may be obtained by combining cover crops with conservation tillage in grain crop production systems. This study was conducted in 1993 and 1994 on a Maury silt loam (Typic Paleudalfs) soil, at Lexington, Kentucky. The

Lack of soil disturbance in no-tillage changes some of the most important basic soil properties. Short-term changes have been well documented by previous research, but little is known about long-term changes. This study was to determine the effects o

As nonpoint source pollution of water becomes more evident, more concern is being focused on the effects of agricultural practices on water quality. This study evaluated the effects of conventional tillage (CT), chisel-plow tillage (CP), and no tilla
