Minerals have two main functions in the body. First of all, many minerals are responsible for building the structures in the body like bones, and teeth. Secondly, minerals help to regulate bodily processes.
Fertilizers are products of the chemical industry. Each soil need a specific fertilizer (with phosphorous, nitrogen, potassium, microelements).
NPK in the ratios the crop you want needs + microelements such as iron, zink ect. the right ratio of nitrogen, phosphate and potash.
phosphates, nitrates, potassium chloride, fertilizers with microelements, natural fertilizers Ex.: ammonium nitrate, urea, ammonium sulphate, sodium phosphate, etc.
solid and liquid, NPK or microelements, cold weather or warm weather, single element or combinations, pH levels, certified for organic use and many many more...
