VISO Fertilizers

Our fertilizer plant is located in Pará where we process the mineral using a calcination (thermal) process, which is an innovative and new method in Brazil. We solubilize phosphate using heat only, with no need to add water or chemical products.

Using this type of fertilizer we can provide greater care for soil health thus aiding plant development and increasing biodiversity. It also increases the diversity and density of organisms that are beneficial to the soil such as bacteria, fungi and insects which have important roles in the decomposition of organic matter, nutrient cycling and carbon fixation in the soil.
