An ecological based sustainability assessing system for cropping system
The assessment of sustainability in cropping system is an important issue for natural resources management and environmental protection. Incorporating the geographical information system (GIS) and remote sensing (RS) technologies, an initial idea of the crop sustainability assessing system was thus proposed, based on ecosystem services value (ESV) assessing criterions. The system is basically c...
متن کاملThe Efficiency of Integrated Pre-Emergence and Post-Emergence Herbicides in Nutrient Uptake by Wheat and Nutrient Depletion by Weeds in Sesame-Wheat Cropping System in Khuzestan
In order to investigate the effect of pre-emergence and post-emergence herbicides on nutrient depletion, weed population and nutrient uptake by wheat in sesame-wheat cropping system in Khuzestan a field experiment was conducted in randomized complete block design with three replications in the research farm of Shahid Chamran University of Ahvaz in 2019-2020. Treatments included no weeding, hand...

متن کاملNitrogen mass balances in conventional, integrated and ecological cropping systems and the relationship between balance calculations and nitrogen runoff in an 8-year field experiment in Norway
For a cropping system to be sustainable, should not only the soil nitrogen (N) content be preserved but also the N runoff be minimised. Finding a simple but robust way to estimate N runoff would thus be a great advantage when evaluating cropping systems. In this study all major N flows in six different cropping systems, each covering 0.18 ha of a separately pipe drained field lysimeter, located...
