Lime And Managing Soil Health
Liming to maintain good soil pH levels and avoiding yield losses is just as important as applying fertiliser for maximising yields. If growers let soil pH levels in the topsoil run-down (pH in CaCl2 < 5.0) they are at risk of creating soil acidity issues at depth which are harder and more expensive to treat. In general, not enough lime has been applied frequently enough to address acidification occurring within the whole soil profile, so soil test to depth and calculate lime requirements for 0-10cm, 10-20cm and 20-30cm, not just the top 10cm of soil.
