Deep incorporation of organic matter - what is actually happening down there? locations
Aims

To determine the effect of subsoil manuring on crop performance, specifically to investigate which component of subsoil manuring gives the crop a boost.

Key messages
  • In year one of this trial, there was no yield differences observed with the application of chicken manure, artificial nutrients or no nutrients
  • Cultivation with the mouldboard plough resulted in better yields compared to no cultivation or deep ripping in the first year regardless of nutrients
  • Grain protein was significantly higher in the chicken manure treatments
  • Large amounts of dry matter was produced under the manured treatments however it didn’t make any difference to yield
