ABSTRACT
The present study analyzes the chemical configuration of a complex NPK fertilizer (approximate grade 10-21-5) that integrates a dual phosphorus release strategy through the combination of polyphosphate and orthophosphate salts. This formulation not only guarantees immediate nutrient availability but also establishes a macromolecular reservoir that resists soil fixation, while enabling the stable coexistence of steroidal phytohormones and essential micronutrients.
INTRODUCTION
The efficiency of phosphate fertilization is one of the greatest challenges in agricultural chemistry due to the high rate of phosphorus insolubilization in the presence of metallic cations. The NPK formula with brassinosteroids, developed by Formulaciones Químicas S.A., addresses this issue through a molecular design that optimizes systemic mobility and nutrient longevity in the rhizosphere.
The stability of a phosphated multimineral concentrate is justified by fundamental properties of coordination compounds and other physical properties. In contrast, the structural efficiency of the mixture is justified through the use of complementary growth hormones and large molecules that constitute long-term nutrients, resistant and compatible with other nutrients such as potassium and nitrogen.
