Effect of crop rotation in soil microorganisms

The Effect of Crop Protection Chemicals on Soil-Dwelling Microorganisms

Microorganisms are an important component of the soil environment, and they play a key role in the decomposition of organic matter, the circulation of elements in the natural environment and the preservation of soil fertility. Microbes enhance the overall health of plants. In the rhizoplane, ectorhizosphere and endorhizosphere, high populations of microbes dwell around plant roots which secrete...

Crop Rotation Impact on Soil Quality

Management systems influence soil quality over time. A study was carried out on Vanmeter farm of the Ohio State University South Centers at Piketon Ohio, USA to evaluate the impact of crop rotations on soil quality from 2002 to 2007. The crop rotations comprised of continuous corn (CC), corn-soybean (CS) and corn–soybean-wheat-cowpea (CSW). Ten soil cores were collected at 0-7.5, 7.5-15, 15-22....

effect of irrigation management with saline waters on soil salinity in the crop rotation

in order to investigate the effects of saline waters on some soil characteristics, this experiment was conducted with three irrigation water salinity treatments contains 1.7-3.4, 8-9 and 11-12.5 dsm-1 (low, medium and high salinity) and two irrigation water managements with four replications in a wheat-fallow-sugar beet-safflower rotation. results show that in (1) irrigation management with low...
