Farms are currently applying some fertiliser to help establish this year’s planting of autumn-sown crops such as wheat, rape and barley. Some of the phosphate, a bit more of the potash and more still of the Nitrogen, will washout into the groundwater casing financial loss and pollution. Over the farming year, depending on soils, between a third and half of all mineral N fertiliser is lost to groundwater. See the diagram and, in the next issue of this blog, how to avoid that loss.
