Soil Conservation Policies and Regulations The adoption of soil conservation practices by farmers is not always an easy endeavor. Surveys conducted show that farmers are less effectively motivated by conservation ethic to adopt soil conservation measures than by economic benefits. However, the surveys als...
engineering and tillage practices,and 32 groups for the second classes and 59 groups for the third classes were identified respectively.This study is to give an example for more research attention and discussions on soil conservation classifications in order to make the classification systems better ...
Here, we conducted a meta-analysis to evaluate crop productivity (i.e., biomass, grain, total yield) and GHGs emissions (i.e., CO 2 , N 2 O, CH 4 ) for three major soil conservation practices i.e., no-tillage, manures, and biochar. We also examined the yield potential of three...
Since 1983 the city has funded soil conservation programs in the lake's watershed. These programs are best management practices (BMPs), and include no-till planting methods, as well as the construction of conservation structures such as terraces, ponds, and grassed waterways. In 1983 the city...
Despite these positive impacts on these services, the impact of physical soil and water conservation practices on crop yield was negative mainly due to the reduction of effective cultivable area by soil/stone bunds. In contrast, most agronomic soil and water conservation practices increase crop ...

The Revised Universal Soil Loss Equation (RUSLE) is a model that predicts the long-term average annual rate of soil erosion based on factors such as rainfall, soil type, topography, crop system, and management practices. AI generated definition based on:International Soil and Water Conservation...
(IT PGRFA;www.fao.org/3/a-i0510e.pdf), or other harmonized best practices examples like the Global Genome Biodiversity Network96. As the commercial value of soil organisms is regarded to be zero in situ111, and as these are mostly ubiquitously distributed at the highest taxonomic level (...
The unit plot was used to compare soil loss data collected on plots that had different slopes, lengths, cropping and management and conservation practices (Wischmeier and Smith, 1965, 1978, p. 58). The main motivation of the early studies using the USLE were to quantify soil erosion rates ...
