Potassium, Calcium,Magnesium- How They Relate to Plant Growth
dolomite, calcite and calcium feldspars. Upon their disintegration and decomposition, calcium is released. Calcium is an extremely important mineral in plant nutrition. Many soils, particularly in humid regions, contain this element in amounts so small that plant growth is limited. Turf-grasses as a group are able to tolerate low levels of calcium; however, abnormal growth has been observed
