The impact different farming systems have on soil nitrogen, phosphorus and potassium—Northern Region locations
Aims

Can systems performance be improved by modifying farming systems? How does increasing legume frequency or nutrient inputs impact on system nutrient balance and use?

Key messages

1. Most farming systems extract more nutrients than are supplied by common fertilisation strategies.
2. Increasing the frequency of legumes doesn’t necessarily reduce nitrogen inputs required across the crop sequence and increases export of potassium.
3. Higher fertiliser application has maintained higher soil mineral nitrogen levels but rarely increased grain yield or total system nitrogen use.
