text: The study of agrominerals is termed agrogeology, and agrogeologists are concerned with issues such as the replenishment of soil fertility in areas where agrominerals have been depleted by unsustainable farming methods. With current farming practice, the system is expected to have high crop production with low soil quality. Over time with this type of practice, ground nutrients have been depleted which has led to an increase in chemical fertilizer usage. Chemical fertilizers have been shown to have runoff and it can contaminate groundwaters and are not economically feasible for third world countries. One of the major sources for chemical fertilizers is potash ore. The other concern with the potash ore is the supply is finite and is running out, hence the increase in pricing. Potash is one of the major sources for potassium and phosphorus and one of the original agrominerals. Finding alternative sources for these agrominerals was a concept that was created to focus on soil remediation, to increase productivity in a low-cost manner. 
  At first agrominerals were used to help recreate soil conditions for exotic plants. These were simple practices that occur on a much smaller scale. These include using perlite to enhance the aeration of the soil, using pumice to control evaporation while one can use vermiculites and zeolites to store moisture. This soil modification was the start of the agromineral concept and has evolved into looking for alternative sources to obtain the three major nutrient elements. Remineralization has been the term created for implementing rock powders into soils as a source of nutrients. This process has been implemented into bigger operations and has found great success in places like Brazil, Germany, Norway, South Africa, Sri Lanka, and Uganda.
