Polish growers see high OSR yields with biologicals

摘要

Growers in Poland are achieving high yields of oilseed rape and winter wheat by using biological products. David Jones meets two farmers going down this route.Polish grower Julian Grygolec is harvesting bumper oilseed rape yields of 5t/ha across his farm with a focus on using biologicalproducts and foliar feeds keep his crops well supplied with essential nutrients.The 5t/ha figure is his average yield across 150ha of rapeseed in the summer of 2022 on his fertile soils in northern Poland, using a relatively low level of nitrogen fertiliser at 180kg/ha.
