Independent trials conducted by ADAS have shown that a balanced autumn Bionature liquid fertiliser regime can double OSR root length. Charlotte Cunningham reports. Results from 2019 crops showed that Bionature’s Delta liquid nitrogen applied at the recommended rate, achieved 104% increase in specific root length, when compared to the non-treated control. According to Mark Carter, Bionature UK director, getting OSR established and away rapidly is important in counteracting various pests and diseases. “Early root development is key to rapid emergence and this is stimulated by readily available nitrogen, so the plant can develop an efficient root system. “Autumn applied Delta liquid fertiliser has a positive charge, which means it sticks to the soil, as well as penetrating it, leading to an increase in nitrogen use efficiency. It also means less nitrogen will be lost through leaching,” adds Mark. Bionature Delta fertiliser is a stabilised nitrogen fertiliser with potassium for improved rooting, stress tolerance, crop quality and yield production. Significant difference North Lincs farmer, Colin Chappell, grew 9ha of oilseed rape this year on heavy clay land and has seen good results with Delta. “We had a much straighter, longer tap root on treated crops than the untreated section of the…
