Saline-alkaline stress, caused by high levels of harmful carbonate salts and high soil pH, is a major abiotic stress that affects crop productivity. Alfalfa is a widely cultivated perennial forage legume with some tolerance to biotic and abiotic stresses, especially to saline-alkaline stress. To elucidate the mechanism underlying plant saline-alkaline tolerance, we conducted transcriptome analy...
Natural biological suppression of soil-borne diseases is a function of the activity and composition of soil microbial communities. Soil microbe and phytopathogen interactions can occur prior to crop sowing and/or in the rhizosphere, subsequently influencing both plant growth and productivity. Research on suppressive microbial communities has concentrated on bacteria although fungi can also infl...
Background In the arid and semi-arid areas of northern China, overexploitation of fertilizers and extensive irrigation with brackish groundwater have led to soil degradation and large areas of farmland have been abandoned. In order to improve the soil quality of abandoned farmland and make reasonable use of brackish groundwater, we conducted field trials in 2013 and 2014. Methods In our study...
Tillage operation and fertilizer type play important roles in soil properties as far as soil microbial condition is concerned. Information regarding the simultaneous evaluation of the effect of long-term tillage and fertilization on the soil microbial traits of soybean farms is not available. Accordingly, it was hypothesized that, the microbial biomass and enzyme activity, more often than not, ...
In this study, a saline-alkaline-tolerant bacterial strain named Paenibacillus sp. C1 was screened and isolated, its basic properties were characterized. Its phosphorus dissolution, organic acid production, application on ameliorating soda saline-alkaline soil studied, the changes of microbial communities after adding with or without rice straws, (NH4)2SO4 Ca3(PO4)2 investigated. The results de...
Trivalent Cr is one of the heavy metals that are difficult to be removed from soil using electrokinetic study because of its geochemical properties. High buffering capacity soil is expected to reduce the mobility of the trivalent Cr and subsequently reduce the remedial efficiency thereby complicating the remediation process. In this study, geochemical modeling and migration of trivalent Cr in s...
The garlic stalk is a byproduct of garlic production and normally abandoned or burned, both of which cause environmental pollution. It is therefore appropriate to determine the conditions of efficient decomposition, and equally appropriate to determine the impact of this decomposition on soil properties. In this study, the soil properties, enzyme activities and nutrient dynamics associated with...
PH (Puissance de Hydrogen) is an essential ingredient of soil that effects on fertility and productivity of dirt. Barddhaman district is a part of Lower Gangetic Plain fully covered by alluvial soil and popularly known as 'rice bowl of West Bengal' owing to its lofty production. This data article provides a block level data on soil PH that is essential for further investigation of the relations...
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...
