उत्तर
Humus is colloidal in nature, meaning it consists of fine particles suspended in the soil. This colloidal structure allows humus to hold and retain mineral ions through chemical bonding, creating a nutrient reservoir. Plants can gradually extract these nutrients, and humus releases them slowly, providing a steady supply of minerals to plant roots.
