Nitrogen Transformations in Soils, Agricultural Plants and the Atmosphere, and nitrogen oxides (NO.) and nitrous oxide (N.O) is observed. When these forms of nitrogen occur at very high concentrations, they may be harmful to the environment (e.g. to cause the acidification of soils, an eutrophication, global warming, toxicity to plants, animals and for people). The monito

Agricultural Bioenergy Production,ntribution of bioenergy has decreased and been replaced by fossil fuels. However, these fossil resources will eventually become exhausted and their use is causing social and environmental problems. Hence in many regions the use of bioenergy is promoted by law. The role of agriculture in the producti

Direct Seeded Rice in South Asia,f rice is water, capital and energy intensive. This system leads to structural deterioration of the soil. Furthermore, aeration stress due to hard pan formation during the rice season modifies wheat yields. Technical training is required to grow mat type nursery and operating of transplanter put mec
