Biological Nitrogen Fixation for Increased Crop Productivity, Enhanced Human Health and Sustained Soil Fertility
نویسنده
چکیده
FAOSTAT 2002 Nitrogen is, with water, the greatest global constraints to agricultural productivity. Sustainable cropping systems throughout history have relied on combining cereals with nitrogen-fixing legumes. However, over last fifty years, cereals have dominated global agriculture, while legume cultivation areas and productivity have stagnated or even declined. Global agriculture is now at a crossroads as a consequence of climatic changes, increased population pressure and detrimental impacts on the environment.

It is important to develop integrated crop production strategies that enhance the productive ability of crops in a sustainable manner for the developing nations worldwide. Intensive farming practice of high yielding crop production is mainly dependent on chemical inputs as fertilizer, pesticide and weedicides. However, excessive use of chemical inputs has negative impact on environment in the f...

The use of renewable resources and inputs is one of the fundamental principles of sustainable agriculture that enables maximum crop productivity and minimal environmental risk. Nutrient management may be achieved by the involvement of organic sources, bio-fertilizers, and micro-nutrients. Indiscriminate use of chemical fertilizers to achieve high yield and to compensate for lack of nutrients an...

Given the limited resources of fossil energy, and the environmental risks of excess fertilizer on crops, it is time to reappraise the potential role of food legume biological nitrogen fixation (BNF) as sources of nitrogen for cropping systems in China. 150 soil samples across 17 provinces and 2 municipalities of China were collected and analyzed. A distribution map of the soil fertilities and t...

For 5 yr we monitored the fertility of a volcanic-ash derived Inceptisol at a site in the humid tropics of Costa Rica. After forest felling and burning, we established four treatments in a randomized block design with six blocks: a sequence of monocultures (two crops of maize [Zea mays] followed by cassava [Manihot esculenta], then the tree species Cordia alliodora), successional vegetation, a ...
