The most widespread practice of using natural zeolites in agriculture is their application directly to the soil, and in mixture with NPK chemical fertilizers, due to their easy industrial processing and low operating costs. However, the results of their use in crops are not observed in short time, while the reproducibility of the results is not entirely positive. The effect on crop yields depends of several variables that are beyond the control of the product. A NPK fertilizer requires water to be solubilized and make the nutrients available for plants. If zeolite particles are present, then only a part of these nutrients can be retained by them.
NEREA® technology allows the production of nanostructured zeolitic materials. Its foundation is the fact that zeolites are naturally part of the soils, so their incorporation into these does not represent ecological damage. The distinction is to introduce steadily into the zeolite particles all the nutrients. Each NEREA® particle contains homogeneously and optimally the nutrients that only plants take up modifying the architecture and morphology of their roots, or directly by the stomata and leave cells.
If the mechanical mixing of zeolite mineral particles with chemical fertilizers has represented an important contribution to agriculture, NEREA® products solve its shortcomings, and represent an innovation for agriculture and zeolite science. This work aims to demonstrate this hypothesis comparing the results of several authors who mixed Cuban natural zeolites with NPK to fertilize beans, rice, potatoes, tomatoes, and sugar cane crops, with the results obtained using NEREA® products.
