Information based agriculture (IBA) includes matching of agronomic practices with soil and water characteristics and their spatial variability for enhancing productivity. An attempt was made to derive agriculture management zones based on soil and water characteristics for sustainable agricultural production in Mansa district (Punjab, India). Based on physiographic analysis and semi detailed so...

salinization is the main characteristic of soils in arid and semi-arid regions which reduce the agricultural potential ofirrigated lands. therefore, soil reclamation as well as determination of the leaching requirement for salt control is veryimportant for better plant growth. in this study, the effects of leaching on saline soils of sistan region, southeast of iranwere examined using unsaturat...

Soil bulk density (BD), degree of compactness (DC), maximum bulk density (MBD), and critical water content (CWC) at which MBD is reached are commonly used to characterize soil compaction, and can be predicted from soil texture and organic matter content, omitting other components such as sand sub-classes and soil cementing agents and potential biases such as data redundancy and sub-compositiona...

Improving the existing knowledge on the enantioselectivity of processes affecting chiral pesticide enantiomers in the environment is necessary to maximize the efficacy and minimize the environmental impact caused by the use of pesticides with chiral properties. In this work, the enantioselectivity of the sorption, degradation, and leaching processes of the chiral fungicide metalaxyl in three sl...

The Earth's atmosphere will continue to be enriched with carbon dioxide (CO2) over the coming century. Carbon dioxide enrichment often reduces leaf transpiration, which in water-limited ecosystems may increase soil water content, change species abundances and increase the productivity of plant communities. The effect of increased soil water on community productivity and community change may be ...

Abstract Soil functions such as water storage, soil filtration, and reducing reservoir life due to sediment load are directly affected by the process of “soil erosion.” The Universal Loss Equation was adopted predict erodibility factor for watersheds feeding Al-Shewicha trough. K -average factor’s determined value 0.156, indicating that -factor had substantial variability. values linked high sa...

This study aimed to evaluate the effect of shrub encroachment on soil organic carbon (SOC) content at broad scales and its controls. We conducted a meta-analysis using paired control data of shrub-encroached grassland (SEG) vs. non-SEG collected from 142 studies worldwide. SOC contents (0-50 cm) were altered by shrub encroachment, with changes ranging from -50% to + 300%, with an effect size of...
