Conservation agriculture (CA) is promoted as a cropping system that has potential to alleviate poor crop yields in smallholder farming while protecting the environment. It involves maintenance of permanent soil cover, diverse crop rotations and/or interactions; and minimum soil disturbance. CA is associated with crop residue management challenges due to low crop biomass yields and crop-livestoc...
increased soil dryness of hillsides and lands around the gully causes the aggravation of the gully erosion which leads to the desertion of the environment. soil moisture contents are various in different soil depths, gully positions, and in various land uses. these are fundamental for ecosystem sustainability in arid and semi-arid area. therefore, understanding the behavior of soil moisture in ...

Abstract Present research has been executed in Chaharmahal va Bakhtiary Province during 5 years in order to develop and establish hillside orchards using rainwater harvesting catchments. The region receives 300 mm of rainfall annually and has a moderate soil texture. Towards this goal, in a rangeland with a slope of 20 percent, microcatchments were made with 5 different treatments inc...

As a p art of a PhD project r esearch about embeddedness in Alternative Food Networks (AFNs), this paper focuses on the promotional aspects of organic farms websites from the Madrid region. As a theoretical tool, some knowledge categories drawn ...
Understanding spatial and temporal variations in river water quality and quantitatively evaluating the trend of changes are important in order to study and efficiently manage water resources. In this study, an analysis of Water Pollution Index (WPI), Daniel Trend Test, Cluster Analysis and Discriminant Analysis are applied as an integrated approach to quantitatively explore the spatial and temp...
BACKGROUND AND OBJECTIVES: Urban farming makes a substantial influence on the household economy of the urban poor especially in developing countries. Urban soil the hot spot of urban farming is a natural sink for contaminants especially the trace elements derived mainly from anthropogenic activities. This study’s aim was to quantify the concentrations of selected trace elements...
