A field experiment was conducted to provide a complete greenhouse gas (GHG) accounting for global warming potential (GWP), net GWP, and greenhouse gas intensity (GHGI) from no-tillage (NT) paddy fields with different amounts of oilseed rape residue mulch (0, 3000, 4000, and 6000 kg dry matter (DM) ha(-1)) during a rice-growing season after 3 years of oilseed rape-rice cultivation. Residue mulch...

The carbon (C) cycle is the basis for greenhouse gas emissions and global warming. Globally, agriculture is responsible for about 20% of the greenhouse gas emissions. However, this percentage does not take into account the large role that agriculture plays in the opposing processes of photosynthesis and respiration (Figure 1), as well as contributions to soil organic C sequestration via animal ...

Pesticides are used on a large scale for agricultural purposes. The adverse effects of pesticides on both human health and the environment are a matter of public concern. Thus both the actual state and residue levels of pesticides in agricultural products should be extensively monitored. One of the new classes of pesticide is the triazole derivatives, which are very effective fungicides. In thi...

A monoclonal antibody-based competitive antibody-coated enzyme-linked immunosorbent assay (ELISA) was developed and optimized for determining chlorpyrifos residue in agricultural products. The IC(50) and IC(10) of this ELISA were 3.3 ng/mL and 0.1 ng/mL respectively. The average recoveries in six agricultural products were between 79.5% and 118.0%, with the intra-assay coefficient of variation ...

One of the major sources of emission of green house gases (GHGs) is biomass burning. Thus the space-based observations of global distribution of fire form a key component of climate change studies. Several international programs have been established towards the goal of gaining complete information on fire activity around the world using space based observations. This study mainly highlights th...

carbon (c) and organic nitrogen (n) mineralization processes play key roles in supplying nutrient elements essential for plant growth. on the other hand, since the low organic matter content of agricultural soils of arid and semi-arid areas, microbial activities are often limited by carbon in these types of soils. enhancement of microbial activities and populations could be achieved by returnin...
