Maize under sown with rye grass, monitoring nitrogen in the soil and potential nitrate leaching

Understanding whether we are over or under applying nitrogen fertiliser. What is our N budget based on? The trial set out to explore this question

These are a great tool for monitoring elements in the ground water. They can be buried up to 1m deep and stay in situ for a whole season allowing for regular assessments of nitrate in the soil profile

This Trial is ongoing and expected to conclude in Spring 2027.
