Carbonized rice hull is made from incomplete or partial burning of rice hull. It undergoes a controlled burning process where the dried rice hull is heated until they are carbonized. CRH (Carbonized Rice Hull) is a very good soil fertilizer and conditioner. CRH contains Phosphorous (P), Potassium (K), Calcium (Ca), Magnesium (Mg), and micronutrients vital to growing crops. It makes the clay soil porous because of its loose composition. It improves soil structure by increasing bulk density, water holding capacity, and aeration. CRH also harbors good bacteria and it serves as houses for microorganisms. With these benefits, CRH is a very good potting media for seed sowing and seeding propagation.
