Soil Phosphatase Activity and Phosphorus Content as Influenced by Catch Crops Cultivated as Green Manure
In a 3-year experiment, the effect of catch crop management [catch crop incorporated in autumn (A) or mulched (B) vs plots without a catch crop (C)] on soil acid (PAC) and alkaline (PAL) phosphatase activities as well as on the available phosphorus content (PAVAIL) were investigated on typical Alfisol. The catch crops were sown at the beginning of August and ploughed in the autumn in 2008, 2009...
متن کاملSunnhemp and Millet as Green Manure for Tropical Maize Production
Commonly N release from legume residues is rapid in the tropics. Legume mixtures with grasses can result in slower nutrient release from residues, better matching the N requirements of the following crop. The objectives of this study were to evaluate the effects of the green manures sunnhemp (Crotalaria juncea) and millet (Pennisetum glaucum), alone or mixed, on the performance of a subsequent ...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولEffects of green manure crops and tillage practice on maize and rice yields and soil properties
Improper tillage with no manure may cause a range of undesirable processes (destruction of soil structure, accelerate erosion, depletion of organic matter and fertility). A field experiment was conducted to observe the change in soil properties after incorporation of green manure crops and to find out the residual effect of green manure crops along with tillage on maize and rice yields during 2...
متن کاملResponse of Maize to Cover Crops, Fertilizer Nitrogen Rates, and Economic Return
17 Maize is the world’s most widely grown cereal on the basis of Mg produced (FAO, 2014). Nitrogen fertilizer applied to cropland is a considerable portion of the cost and energy input associated with nonlegume crop production (Liebman et al., 2012). When N is lost from cropland, it represents both a fi nancial loss to producers and has a potentially negative impact on the environment (Vetsch a...
