Crop Nutrition

Farmers have the big responsibility of nourishing a growing population. Prince helps by having the largest range of manganese-based products for crop nutrition.


Manganese plays a key role in several crop physiological processes, particularly in photosynthesis. Manganese plant deficiency is a widespread problem most often occurring in sandy soils, organic soils with pH above 6, and heavily weathered tropical soils.
