Sehlopha sa manyolo

Mefuta ea menontsha e ka aroloa ka bophara ka mefuta e 'meli: menontsha ea inorganic le manyolo a tlhaho.
Manyolo a tloaelehileng a lik'hemik'hale a kenyelletsa manyolo a naetrojene ea elemental, menontsha ea phosphate le menontsha ea potash, manyolo a motsoako oa likarolo tse peli, manyolo a motsoako oa likarolo tse tharo le menontsha ea metsoako e mengata, hammoho le manyolo a motsoako oa organic-inorganic.
Manyolo a inorganic ke menontsha ea lik'hemik'hale, joalo ka naetrojene e fapaneng, phosphorus, menontsha ea potash kapa manyolo a kopaneng.Manyolo a lik'hemik'hale a atisang ho sebelisoa indastering ea ho lema a kenyelletsa: diammonium phosphate, urea, potassium sulfate, potassium chloride, le menontsha e fapaneng ea metsoako.Manyolo a sebetsang nako e telele joalo ka superphosphate le ona a ka sebelisoa sefateng sa litholoana
