Tilling Your Cover or Complex Ley; Relative Merits of Strategies

NIAB Seminar Tent

As part of their long-term soil improvement, many farmers have successfully integrated winter cover crops into their rotation. Some have the long term aim to minimise or even eliminate exposure of bare soil at any time throughout the year. Others have taken this theme a step further and have introduced longer term use of cover crops into the spring or even summer; while a growing minority are introducing leys into the rotation with a two to three year life expectancy, before returning to arable cropping.
But the question remains; what is the best strategy when preparing the soil for return to arable, and how is this is impacted both now and in the future by loss of chemistry?
