Vetch termination: impact on the following wheat crop locations
Aims

To compare the effects of (i) five different vetch termination timings, and (ii) five different end-uses of vetch on stored soil water and mineral N, and the yield of a subsequent wheat crop.

Key messages

Early termination of vetch resulted in higher soil N and soil water at sowing the following year compared with later termination timings of vetch. Wheat yield in the year following vetch was highest for the earlier termination timings of the vetch. Brown manure vetch had higher soil N and soil water compared to vetch taken through to harvest.
