Abstract:
... In the United States, current crop production often favors simplified rotations of maize and soybeans in conjunction with a heavy reliance on synthetic inputs that consequently degrade environmental health and increase production costs, without necessarily improving yields. While often stigmatized as underperforming compared to conventional systems, “sustainable intensification” of cropping system ...

Abstract:
... There is growing evidence for a positive non-linear response in N₂O emissions where increasing N fertilizer rates critically exceed crop requirements from a range of cropping systems. However, the majority of these studies have been conducted in temperate regions, and it remains unclear if the non-linear response hypothesis can be transferred to tropical regions due to their inherently lower carbo ...

Abstract:
... Nitrous oxide (N2O) is the most important greenhouse gas produced by agricultural soils and is a byproduct of microbial nitrification and denitrification processes. The N2O emission rates depend on soil, climatic and management factors. The objectives of this study were i) to evaluate N2O emissions during a barley crop period and its subsequent barley-maize interperiod, under two management system ...

calcium; carbon sequestration; carbon sinks; carbonates; corn; crop rotation; cropland; intensive cropping; magnesium; river deltas; semiarid zones; soil organic carbon; soil profiles; soil salinization; wheat; China; Yellow River
Abstract:
... There is evidence of higher levels of pedogenic carbonate (PIC) than soil organic carbon (SOC) in cropland, and a positive relationship between PIC and SOC in salt-affected soils of arid and semi-arid regions. This study is designed to test the hypothesis that PIC is influenced by intensive cropping and salinization in semi-humid regions, in which soil carbonate (SIC) often exceeds SOC. We select ...

5. How do agricultural practices affect the movement behaviour of European brown hares (Lepus europaeus)?

Abstract:
... Agricultural landscapes are spatially and temporally dynamic habitats that force wildlife to interact with different management practices, such as harvests and mowing events which cause sudden changes in resource availability. Animals may avoid agricultural management events and the changed habitat, to search for undisturbed areas or they might use and explore such areas due to beneficial changes ...

Abstract:
... Fall armyworm (FAW), one of the most important pests of maize in Latin America, suddenly appeared in Africa in 2016 and spread rapidly. Estimates of crop losses due to FAW are essential in order to compare the impact of these losses with the cost of controlling FAW and advise appropriate technology dissemination and policy. In this study, therefore, crop losses due to FAW in 2017 and 2018 were est ...

Abstract:
... Drip irrigation under plastic film mulching with applications of the N-fertilizer is an excellent agricultural strategy, resulting in saving irrigation water, improving N use efficiency, and increasing crop yield. However, the film residue and nitrate-nitrogen (NO₃-N) losses are the leading cause of non-point pollution in agricultural fields. To promote the development of sustainable agriculture, ...
