Soil resistance and bulk density under different tillage system

Assessing Photosynthetic Leaf Area of Corn under Different Tillage Systems and Soil Zones

The photosynthetic leaf area may be influenced by soil texture. The objective of this experiment was to evaluate photosynthetic leaf area under different soil textures, based on soil electric conductivity (EC) measurements, tillage systems, and N rates in dryland corn (Zea mays L.) from 2007 to 2009. A commercially available soil electric conductivity (EC) measurement system (Veris Technologies...

Impacts of different tillage practices on some soil microbiological properties and crop yield under semi-arid Mediterranean conditions

Effects of six tillage practices on some soil microbiological properties and crop yields were evaluated for a clay soil (Typic Haploxererts) under semi-arid Mediterranean conditions in a three year study (2006-2009). The experiment was designed as a completely randomized-block with three replications. Treatments were: conventional tillage with residue incorporated (CT1), conventional tillage wi...

Tillage and soil quality Tillage practices for sustainable agriculture and environmental quality in different agroecosystems

For centuries tillage has been used to prepare suitable seedbed to grow crops, and to control weeds and incorporate fertilizers, pesticides, manures and other amendments. In early years conversion of native ecosystems by tillage helped to unlock nutrients stored in soil organic matter, and thus `mine' naturally fertile soils to grow crops with minimum inputs for the growing population. However,...

Swelling Bulk Density and its Application in Arya and Paris Model for Soil Moisture Curve Prediction

Oxidation Potentials of Soil Organic Matter in Histosols under Different Tillage Methods

a mineral soil (Farnham and Finney, 1965), which provides a high potential for diffusion and storage of O2 Organic soils in the Everglades Agricultural Area (EAA) of southfor microbial utilization in the organic soil. Neller (1943) ern Florida, USA, are subsiding due primarily to oxidation by aerobic microorganisms. Since there are large C losses in drained Histosols, reported that soil O2 rang...
