Alleviating Soil Acidity with Crop Residues
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 t...
متن کاملInteractive Effects of Salinity and Cadmium Pollution on Enzyme Activity in a Calcareous Soil Treated With Plant Residues
Abiotic stresses such as salinity and contamination individually have a negative effect on the soil enzyme activities, whereas addition of organic matter to soil can alleviate the negative impacts of stresses on the enzyme activity. However, the combined effects of these stresses (multiple stresses) on soil biochemical conditions and the role of organic matter addition in these interactions are...
متن کاملEffects of Arbuscular Mycorrhizal Fungi and Soil Conditions on Crop Plant Growth
We investigated the effects on various crops of inoculation with species of arbuscular mycorrhizal fungi (AMF) in soils from different sources and selected AMF species suitable for domestic environment-friendly farming. Effects on plants varied with the AMF species used. In carrot, Scutellospora heterogama, Acaulospora longula, and Funneliformis mosseae had a positive effect on growth of the ho...
متن کاملPhysical effects of soil drying on roots and crop growth.
The nature and effect of the stresses on root growth in crops subject to drying is reviewed. Drought is a complex stress, impacting on plant growth in a number of interacting ways. In response, there are a number of ways in which the growing plant is able to adapt to or alleviate these stresses. It is suggested that the most significant opportunity for progress in overcoming drought stress and ...
متن کاملEffect of different growth stages on rice crop on soil microbial and enzyme activities
The influence of growth stages of rice on soil microbial biomass carbon (MBC), soil microbial biomass nitrogen (MBN) and enzyme activities (amylase, dehydrogenase, alkaline and acid phosphatase) in a sub-tropical rice field has been screened. The above soil parameters were investigated at two soil depth (0-10 and 10-20 cm) and in five growth stages of rice crop, i.e. 30, 60, 90, 120 and 150 day...
