Land use change as the most important destructive factor in natural ecosystems is a globally problem that changes soil properties. Therefore, correct management and recognition of change aspects on each component of the ecosystem is necessary. This process causes land destruction, ecosystem instability, soil erosion, and more biological threats. Due to increasing land use conversion from rangel...
Clustering was used to divide dryland farming areas in western Iran into homogeneoussub-regions to identify dryland farming potential, considering drought impacts. Clusteringutilized eight algorithms/four indices to detect optimal number of clusters. Ward’s algorithmvalidated by Silhouette index, produced the best result by detecting 7 dryland farming clusters.Based on similar P/ETo values, fou...
Dryland cereals and legumes are important crops in farming systems across the world. Yet they are frequently neglected among the priorities for international agricultural research and development, often due to lack of information on their magnitude and extent. Given what we know about the global distribution of dryland cereals and legumes, what regions should be high priority for research and...
This review paper attempts to bring together different issues in the light of recent developments in organic farming. The after effects of green revolution have encouraged the farmers to take up organic farming. This paper has reviewed the global and Indian scenario with reference to organic farming. In India, the cultivated land under certification is 2.8 Mha only. The key issues emerging in o...
In dryland farming areas of Montana, annual precipitation is not sufficient for annual planting of cereal grains. Instead, a crop-summer fallow farming system is used to conserve soil moisture and increase available nitrogen for subsequent crop growth. Managing this summer fallow, either by mechanical means or with herbicides, is the highest variable cost associated with dryland grain productio...
