This project aims to develop improved guidance to farmers on sulphur (S) management by reviewing current "Fertiliser Manual (RB209)" S recommendations for oilseed rape (OSR) and cereals, and quantifying the S supply from applications of organic materials. We will do this by:
1. Reviewing existing experimental data on S responses in OSR and cereals.
2. Determining optimum S rates from additional field experiments on OSR.
3. Characterising manure total and extractable S content.
4. Quantifing the S... more
