BIO SSP  is a 100% natural solid fertilizer, an important source of phosphorus for agricultural crops.

Phosphorus is one of the 17 chemical elements necessary for plant growth and reproduction, it is called an “energizer” because it helps store and transfer energy during photosynthesis. Phosphorus is an essential nutrient in plant growth and development, being part of several essential compounds such as enzymes, carbohydrates, etc. as well as a catalyst in the synthesis of the many biochemical reactions that take place in the plant. It is also part of the genetic material of all cells – DNA and RNA.

Through its content, the cationic exchange capacity of the soil is increased, which allows the soil to retain positively charged nutrients such as; calcium, potassium, magnesium and trace elements.

The application of an optimal amount of phosphorus in the crop ensures a strong development of the roots, optimal growth of the stem, the formation of flowers, an increase in the number of seeds, uniform and early ripening of the crop. Plants absorb phosphorus during the entire period of growth and development, but most intensively at the beginning of vegetation, being essential for the development of the root system. Phosphorus also gives early ripening character.

Sulfur is an essential plant nutrient. It is necessary for the production of amino acids, which make up the proteins essential for plant growth. First, sulfur, when converted by bacteria to sulfuric acid that reacts with insoluble mineral forms and oxidizes them to become nutrients available to cultivated plants, lowers soil pH, increasing plant root access to many nutrients..Secondly , sulfur plays a critical role in the formation of proteins in plant tissue and in the formation of vitamins. By mixing phosphate rock with sulfur, a better availability of phosphorus is obtained, resulting in more sustained plant growth and better quality production.

Calcium oxide (CaO) dissolves rapidly in soil, and the released calcium ions bind to soil particles and enhance flocculation, forming micro-aggregates in soils with high clay content and cation exchange capacity. It allows the neutralization of soil acidity by adjusting the pH, which helps prepare the soil to help the crop absorb nutrients in excellent conditions. Opens up the soil, allowing water to be better absorbed, helping other nutrients to be more available and reducing erosion
