Metrics details. Environmental stress is a crucial factor restricting plant growth as well as crop productivity, thus influencing the agricultural sustainability. Biochar addition is proposed as an effective management to improve crop performance. However, there were few studies focused on the effect of biochar addition on crop growth and productivity under interactive effect of abiotic stress e. This study was conducted with a pot experiment to investigate the interaction effects of drought and salinity stress on soybean yield, leaf gaseous exchange and water use efficiency WUE under biochar addition. Drought and salinity stress significantly depressed soybean phenology e. Salinity stress significantly decreased photosynthetic rate, stomatal conductance, intercellular CO 2 concentration and transpiration rate by
Continuous monoculture of cool-season turfgrass causes soil degradation, and visual turf quality decline is a major concern in black soil regions of Northeast China. Turf mixtures can enhance turfgrass resistance to biotic and abiotic stresses and increase soil microbial diversity. Understanding mechanism by plant-soil interactions and changes of black soil microbial communities in turf mixture is beneficial to restoring the degradation of urbanized black soils and maintaining sustainable development of urban landscape ecology. In this study, based on the previous research of different sowing models, two schemes of turf monoculture and mixture were conducted in field plots during — in a black soil of Heilongjiang province of Northeast China. Turf performance, soil physiochemical properties, and microbial composition from rhizosphere were investigated.
We studied the effects of Acacia seyal Del. A split-plot design with three replications was used. Acacia intercropping significantly reduced sorghum grain yields while biochar had no significant effect on sorghum yields. The land equivalent ratio LER for sorghum yield was 0. The reduction in sorghum yields by the A.
A total of 27 composite soil samples were randomly collected from the CLUS for soil analysis. Data were subjected to one-way analysis of variance and PCA. The lowest and highest bulk density was determined from NF 1. The highest CEC The highest soil OC stock Such soil properties and nutrient stocks variability among the CLUS suggested that introduction of suitable management practices that sustain the soil system of the CLUS with poor soil properties and nutrient stocks are crucial for the study area conditions. Soil quality is becoming an important resource to raise crop productivity so that to meet the food required for the current and future population in developing countries as their economy mainly depends on agriculture [ 1 — 6 ].
Ethiopia, where only 30% of the total waste is collected and disposed on landfills . converting organic wastes into compost, and it has advantages over other biochar alone application to soil can improve soil fertility and plant experiments were khat (Catha edulis) straws, dry grass and leaves.
The invasion success of exotic plants strongly depends on soil properties of new ranges, however, little is known about the joint contribution of soil abiotic and biotic legacies to this success. To address the role of soil abiotic and microbial properties in plant invasions and associated mechanisms, we conducted two complementary experiments. In the first experiment, we grew invasive Solidago canadensis in regular soils from its different invasion stages and measured plant growth to address the joint contribution of soil abiotic and microbial properties. The growth of S. Bactericide had no effects on S.
