Calcite formation in soils can cause problems with infiltration and permeability. This problem can be exacerbated by a variety of factors, including poor irrigation water quality and prolonged periods of drought or abnormally dry weather conditions.
A common test to determine whether a soil contains calcium carbonate is a “Fizz” test. During this test, a dilute hydrochloric acid solution is poured onto a soil sample. If it “fizzes” and a gas is given off, calcium carbonate is present. This test can be used to determine if the entire soil is calcareous or if there is a layer of calcium carbonate at a certain depth in a non-calcareous soil, when a soil core is tested.
What can you do to combat this calcium carbonate layer if it is detected?
Blast is a unique acid formulation combined with Synergy Technology that safely dissolves carbonate build-up in the soil, rapidly opens soil pores for better infiltration and percolation of water, and frees up calcium, magnesium and other bound nutrients. It is available in both a sprayable and injectable formulation.
