Agriculture in India has shifted to intensive cropping of high yielding varieties which has led to depletion of soil nutrients. While primary nutrients (NPK) have been used sufficiently, secondary macro nutrient application has been ignored. Triguna™ can be used to improve poor soils, or to rebuild soils which have been damaged by improper nutrient management. They can make poor soils more usable, and can be used to maintain soils in peak condition. In the integrated nutrient management approach, soil conditioners are integral part of the agronomic package. Calcium is one of the secondary nutrients important for crop production and has role in improving colour, lustre and quality of fruits. Improves soil structure and water infiltration in soil and protection against pests and diseases. Improves water holding capacity. Corrects or prevents magnesium deficiency, stunted growth, and reduced yields. Promotes chlorophyll production. It increase the iron utilization in crop plants. Activator and component of many plant enzymes. Helps in the uniform maturity of crops. Formation of chlorophyll that permits photosynthesis through which plants produce starch, sugars, oils, fats, vitamins. Promotes the nodules formation in legume crops. Increases crop yields and improves produce quality.
