Clay application rates and degree of clay incorporation 2009 Trial details Method Trial results Climate Trial report and links

Plain text source: 
To demonstrate what clay rate is required for claying to be successful and to look at how this is affected by the degree of clay incorporation... Key messages - As the clay rate increased with shallow incorporation using offset discs the yield benefit tends to decline (Table 1), with essentially no difference in yields at the two highest rates of 360 and 450 t clay/ha... - Trial confirms expectation that the degree of incorporation needs to be commensurate with the rate of clay applied - determining this relationship based on the clay content of the subsoil being spread and the level of incorporation to be used is likely to be the key to more reliable claying success...
