Research Paper On Soil And Water Conservation

Practical, as well as process-based research, are welcome in this Special Issue.We would like to focus both on green and blue water: With the purpose of showing novel measuring and modeling approaches, including interactions between soil physical and hydraulic properties, soil water conservation and crop yield.

A good understanding of human impact on the natural environment is therefore necessary to preserve and manage soil and water resources.

This knowledge is particularly important in semi-arid and arid regions, where the increasing demands on limited water supplies require urgent efforts to improve water quality and water use efficiency.

is an international peer-reviewed open access monthly journal published by MDPI.

Upon harvesting, the main growth and nutritional parameters were determined on the aboveground and belowground portions of the lettuce.

Leaf nitrate content, water, and nitrogen use efficiency were recorded; the relationship of lettuce aboveground dry biomass with nutrient uptake was evaluated using vectorial analysis; and ultrastructural analysis of lettuce roots was performed by scanning electron microscopy.

This Special Issue collects 15 original contributions addressing the state of the art of soil and water conservation research.

Contributions cover a wide range of topics, including (1) recovery of soil hydraulic properties; (2) erosion risk; (3) novel modeling, monitoring and experimental approaches for soil hydraulic characterization; (4) improvement of crop yields; (5) water availability; and (6) soil salinity.

By comparison with the recent literature, we inferred a positive physiological response by more expanded and less thick leaves in lettuce, likely by the optimization of the crop water and nutrient root uptakes mediated by the abundant but shortest lateral roots.

This finding corresponded to the lowest leaf nitrate content, indicating an improvement of the lettuce quality without losing the crop yield. Each colored point is a vector, where plant aboveground weight is the x-value and the relative concentration of each nutrient is the y-value, under F S0.2 (dotted ellipse: 0.2 m L) surfactant application by fertigation.
