Results of modelling studies for the evaluation of water quality impacts of agricultural conservation practices depend heavily on the numerical procedure used to represent the practices. Herein, a method for the representation of several agricultural conservation practices with the Soil and Water Assessment Tool (SWAT) is developed and evaluated. The representation procedure entails identifying...

From the first awareness of agricultural sources of water pollution in the US in the 1960s, we finally see in the 1990s a commitment at the national level for agricultural non-point source (NPS) pollution control. This has been occasioned by a growing awareness that, with point sources of some pollutants largely controlled by waste-water treatment, greater attention must be paid to NPS pollutio...

Appropriate agricultural practices for carbon sequestration and emission mitigation have a significant influence on global climate change. However, various agricultural practices on farmland carbon sequestration usually have a major impact on greenhouse gas (GHG) emissions. It is very important to accurately quantify the effect of agricultural practices. This study developed a platform-the Deni...

the study was carried out among potato farmers in ardabil plain, to investigate their attitude towards sustainable agricultural practices. it was comprised of a stratified sample of 140 farmers from two townships (ardabil and naming) who were operating in 24000 hectares of potato farms. descriptive survey research was employed in the study. data were gathered using a questionnaire and through i...

The wide range of plant and animal species that live on the planet – referred to as biodiversity – is now being threatened by intensive agriculture. A growing human population, however, also entails growing needs, which, in turn, requires current agricultural practices to maximize the use of available land while minimizing damage to the environment and biodiversity. Genetically modified (GM) cr...

Background: Conventional cattle ranching and agricultural practices have severely degraded and fragmented tropical forests in Latin America. This trend has resulted in the loss of a range of ecosystem services upon which humans depend, especially those that support agricultural production, such as biodiversity, the provision of water and soil fertility. Consequently, conventional cattle ranchin...

The main purpose of the present study was to assess the ecological capability of agricultural soils using geographic information system (GIS). This research was conducted during 2014 in Hamedan Province, Iran. A cross-sectional study was conducted mapping the 10 factors of soil characteristics (texture, depth, erosion, and aggregation, percentage of slope, direction of slope, height, soil salin...
