| Popis: | Thermochemical synthesis offers possibility of getting effective compound fertilizers from low-grade poorly enrichable mineral raw materials. Agricultural field tests demonstrated that the compound fertilizers developed are much more effective than equivalent doses of the starting components equalized in terms of nitrogen and potassium. Consequently, apatite-based compound fertilizers can be used to radically improve soil fertility (phosphoritization with simultaneous improvement of the nitrogen-potassium regime). |
