متن کاملIndirect N 2 O Emissions from Agriculture
Agricultural perturbations to the global nitrogen cycle, directly and indirectly, lead to enhanced biogenic production of nitrous oxide (N2O). Direct pathways include microbial nitrification and denitrification of fertiliser and manure nitrogen that remains in agricultural soils or animal waste management systems. Indirect pathways involve nitrogen that is removed from agricultural soils and an...
متن کاملAccounting for soil biotic effects on soil health and crop productivity in the design of crop rotations.
There is an urgent need for novel agronomic improvements capable of boosting crop yields while alleviating environmental impacts. One such approach is the use of optimized crop rotations. However, a set of measurements that can serve as guiding principles for the design of crop rotations is lacking. Crop rotations take advantage of niche complementarity, enabling the optimization of nutrient us...
متن کاملImpacts of chemical crop protection applications on related CO(2) emissions and CO(2) assimilation of crops.
BACKGROUND A major global challenge is to provide agricultural production systems that are able to sustain growing demands for food, feed, fibre and renewable raw materials without exacerbating climate change. Detailed and reliable data on the CO(2) balance of different agricultural management activities and inputs as a basis to quantify carbon footprints of agriculture are still lacking. This ...
متن کاملMethane production through anaerobic digestion of various energy crops grown in sustainable crop rotations.
Biogas production is of major importance for the sustainable use of agrarian biomass as renewable energy source. Economic biogas production depends on high biogas yields. The project aimed at optimising anaerobic digestion of energy crops. The following aspects were investigated: suitability of different crop species and varieties, optimum time of harvesting, specific methane yield and methane ...
