How Much Lime is Required to Raise my Soil pH?
The quantity of lime required to increase soil pH varies, typically clay soil requires more lime than a sandy soil. However, as a rough estimate you should apply 0.1 kg of ground limestone to a square meter of soil for an increase in soil pH of 0.1 pH units. For example, to increase soil pH from 5.7 to 6 (a pH suitable for growing grass) would require 0.3 kg lime per square meter of soil. Note, it is important not to add too much lime at one time; generally the maximum is 0.4 kg per square meter.If you need to add more than 0.4 kg per square metre it’s best to do it over one or two years and test the soil between applications. How Do I Apply Lime to My Soil? Calculate how much lime is required for the size of area to be treated. Divide the pile into two halves. Walk across your garden from top to bottom (north to south) and using a scoop apply the lime in a semi circular casting action so that once at the bottom of the garden no lime is left and the area is evenly covered. Repeat the p
