Organic fertilizer can be used to increase crop yield in plants grown in rotation

A study published in the journal Biological Agriculture & Horticulture assessed soil nitrogen oxidation through field incubation, and analyzed the rate of nitrogen release by commercial fertilizers compared with farmyard manure compost. For the study, a three-year organic crop rotation was set up in a field with sandy loam, with a cover crop of rye and vetch for green manure. […]

Natural weed control: Organic farmers use woodchip mulch to control weeds, increase crop yields

Woodchip mulching can suppress weed growths under field conditions, according to a study published in Agronomy Journal. Using a 16-year field trial of woodchip mulching, researchers demonstrated that not only does it diminish the development of weeds, it also does not affect the yield of the crops when it is used. Mulch – a general term for anything […]

Scientists find a way to increase soybean yield through biological fixation, could remove the need for nitrogen fertilizers

Nitrogen fertilizers are a double-edged sword for soybean farmers. While they’re vital for large crops, they’re also expensive and potential pollutants. Thankfully, Brazilian researchers found a different way to boost yields by increasing the number of nitrogen-fixing bacteria in the plant’s roots, according to a ScienceDaily report. Nitrogen is essential to the production of protein. Soybeans […]
