K-Forte – Mineral Fertiliser


At times of stress, before flowering, and peak fruit/crop growth, the need for Potassium and Phosphorus increases.

Most crops suffer from Potassium and Phosphorous deficiencies during these stages despite high soil levels. Foliar applications become the only feasible approach to bypass the soil’s ‘lockup’. The choice of the foliar material, their formulation, timing, and rate of application are essential for a proper response.

The choice of the foliar material, their formulation, timing, and rate of application are essential for a proper response.
