Soil fertility and maximising growth in the coming weeks
About this episode
William Burchill, Lecturer in Soil Science in UCC, joins Stuart Childs on this week’s Dairy Edge podcast to discuss lower than normal growth rates in 2024 and advice on what to do over the next number of weeks to maximise growth.
William first outlines the factors that drive mineralisation with oxygen, wet and dry cycles and soil temperature all contributing to this process.
He discusses the importance of soil fertility in mineralisation and how pH is the gatekeeper for soil biology, which may have a role in alleviating some of the compaction that may have occurred early in the year but it is also the gatekeeper for mineralisation too, so the importance of lime can’t be stated enough with respect to grass swards but even more so with grass clover.
William finishes by explaining the rates of nitrogen for the autumn and the timing of them as well as discussing the role of organic nutrients such as slurry which has to be used by the end of September and soiled water in keeping adequate nitrogen available to deliver growth in the latter part of the autumn.
