Calcium Fertilizer – this product contains calcium which is an essential macro nutrient for plants. It is also used for soil conditioning, both to reduce acidity and to make heavy clay soils more workable. In Kenya most soils are excessively acid, due to leaching of forest soils by heavy rainfall and also due in many cases to continued use of nitrogenous fertilizers, most of which are acidifying. If lime is not used to correct this we will suffer reduced yields and continuing food insecurity. Field trials in various parts of the country have shown the benefit to be obtained from increased yields of most crops by the application of lime to the soil without use of additional fertilizers.
