Answer 2

It is rich in nutrients, which is important for fertility

• Humus is the most important component of the soil. Consists of partially decomposed organic matter.
• It makes the soil porous, increasing its ability to retain air and water.
• Humus is rich in nutrients that promote plant growth.
• lSoils that have a high guck content, have an abundant living natural exertion to convert factory remainders, splint waste, beast soil and colorful biomass into stable guck
• Humus gives the soil the capability to absorb and retain humidity. similar soils don't dry out and bear significantly lower irrigation.
• Humus provides a force for the factory nutrients available in the soil for balanced factory growth.
• Humus plays a part in supporting soil bacteria, similar as Rhizo bacteria, important for all legume nodulation and other well- known bacteria, similar as the phosphate solubilizing bacteria
• An exudate from bacterial exertion results in polysaccharides( a sticky substance) being released, which helps bind the small soil patches into a nutty scruple structure to a depth of 30 cm or further
• Humus also supports the each-important mycorrhizal fungi, which form a symbiosis with numerous shops and are an important factor in the soil food web.
