Alleviating Soil Acidity with Crop Residues
نویسنده
چکیده
Soil acidity, which is characterized by mainly aluminum (Al) toxicity and often calcium (Ca) deficiency, is a serious constraint for crop production in many regions of the world. Soil acidity is traditionally corrected by applications of lime (CaCO3 or Ca(OH)2), which raise soil pH, precipitate Al and provide Ca. However, high rates of lime cannot be afforded because of its high cost relative to the value of some farm products; lime also may not be available in certain regions. Fortunately, recent research has shown that additions of locally available green or animal manures could reduce Al toxicity and increase crop yields.

The Relationship Between the Chemical Forms of Copper in the Soil Solid Phase Affected by Crop Residues With Phytoavailability of Copper in Soil
Returning crop residues into the soil as a source of organic matter are an important source of copper and can play an important role in the soil fertility. In addition to the role of the organic matter in increasing the concentration of micronutrients in soil solution, attention should be also paid to the role of the kind and the quantity of the root’s exudates released in response to the incor...

متن کاملDifferential Soil Acidity Tolerance of Tropical Legume Cover Crops
In tropical regions, soil acidity and low soil fertility are the most important yield-limiting factors for sustainable crop production. Using legume cover crops as mulch is an important strategy not only to protect the soil loss from erosion but also to ameliorate soil fertility. Information is limited regarding tolerances of tropical legume cover crops to acid soils. A greenhouse experiment wa...
