A trial run by South East Water has used soil data to better understand timing and drivers of nitrate risk in order to inform targeted, evidence-led crop management. It says this could help reduce the amount of fertiliser wasted and leaching into waterways and groundwater, benefiting both farmers and water companies. Results showed that: Cover crops consistently showed the lowest nitrate losses Bare soils and stubbles were higher-risk, particularly during wet periods Winter wheat showed higher losses in winter, underlining the importance of autumn and early-season management Rainfall and recharge events are the main drivers of nitrate movement, not single…
