Effects of restoration age on water conservation function and soil fertility quality of restored woodlands in phosphate mined-out areas

Soil and water conservation (SWC) is being advocated as an integral part of agricultural land management as it not only controls/minimizes soil erosion but also restores/rehabilitates the degraded lands. The purpose of this study was to evaluate the impact of soil and water conservation practices in improving soil fertility in the agricultural landscapes of the Damota area, southern Ethiopia. Forty-eight soil samples (both disturbed and core samples) were collected from the conserved and adjacent nonconserved plots. The significance analysis test was performed using analysis of variance. The result of the study showed that higher mean values of soil physicochemical properties were observed in the conserved plot than its nonconserved counterpart. The mean differences of organic carbon, total nitrogen, cation exchange capacity, and exchangeable K+ and Ca2+ between conserved and nonconserved plots were statistically significant at the P < 0.01 level. Besides, available phosphorous and bulk density were significant at P < 0.05 , but the effect of SWC practices was not found significant on soil texture, soil pH, and exchangeable Na+ and Mg2+ content of the soil in the Damota area. Community-based soil and water conservation practices have improved the soil fertility in agricultural landscapes, although significant results have been observed in some fertility indicators. Therefore, strengthening the implementation of conservation measures by participating in all stakeholders is recommended. Supporting physical structures by agronomic and vegetative measures and continued maintenance can bring better results.

The evaluation on the implementation effect of the standard not only constitutes an important basis for promoting the implementation and the quality of the standard, but also provides an important technical basis for implementing national water conservation actions and achieving the dual control targets for water consumption and intensity. This article analyzes and evaluates the implementation effect of the National Standard GB/T18916.1-2012 Norm of Water Intake-Part 1: Fossil Fired Power Production from three aspects including the Standard’s technical indexes, implementation effect and implementation benefits, and provides a foundation and reference to study and conduct evaluations on the implementation effect of the national standard for the norm of water intake.

Abstract The chapter highlights the potential benefits associated with the use of insect-rearing residues as biofertilizers while exploring the mechanisms by which chitin in insect frass might control common crop pathogens. The potential benefits for soil fertility derived from the use of insect frass, comparison of quality of insect-derived biofertilizers and common organic and inorganic fertilizers and insect frass and plant health improvement are discussed. While more research is essential to understand the true value of insect-derived biofertilizers for plant and soil health, preliminary findings suggest there are significant opportunities for beneficial impacts in agriculture and horticulture to be realized.
