Impact assessment of pre- and post-sown irrigation with Post Methanation distillery Effluent on soil health and crop yield
Field experiments were conducted to assess the optimum dilution of Post Methanation distillery Effluent (PME) to utilise as an organic nutrient source for growing rice and wheat crops. Dilution levels of distillery effluent significantly affected the biomass production as well as grain yield of rice and wheat crops. Levels of organic carbon and NPK were significantly higher in effluent treated ...

Animal behavior and soil nutrient redistribution in continuously stocked pensacola bahiagrass pastures managed at different intensities
Animal excreta return to pastures plays a major role in nutrient cycling. Improvement in excreta distribution may increase nutrient recovery by pasture plants. Pasture management may modify animal behavior and excreta distribution. This study evaluated the effects of management intensity on animal behavior and soil nutrient concentration in continuously stocked ‘Pensacola’ bahiagrass (Paspalum ...

New approaches are needed for another Green Revolution
Twenty-first century agriculture needs low-input advances like the System of Rice Intensification, says Norman Uphoff. According to the principle of diminishing returns, continuing to produce something in the same way, with the same inputs and technology, usually becomes less productive over time. This appears to apply to agriculture's 'Green Revolution', as yield improvement has slowed in ...

Climate change to worsen drought, diminish corn yields in Africa
Original story at MIT News Nearly 25 percent of the world’s malnourished population lives in sub-Saharan Africa, where more than 300 million people depend on corn, or maize, as their main food source. Maize is the most widely harvested agricultural product in Africa and is grown by small farmers who rely heavily on rainwater rather than irrigation. The crop is therefore extremely sensitive ...
