By enhancing soil structure and encouraging root development, biofertilizers can indirectly affect soil compaction. Although biofertilizers do not it self immediately reduce soil compaction, their effects on plant development and soil health can eventually result in lessened soil compaction. How biofertilizers affect soil compaction are as follows:
Improvement of soil structure: Some biofertilizers contain microorganisms that make glue- and polysaccharide-producing chemicals. These chemicals aid in the formation of aggregates by binding soil granules together. Larger pore spaces produced by soil aggregates enhance soil structure by facilitating better water uptake and root penetration. Because they resist the forces that cause soil particles to pack tightly together, well-structured soils are less likely to get compacted.
Root system development: Biofertilizers that promote plant growth, such as mycorrhizal fungi and bacteria, can improve the development and branching of roots. Compacted soil layers can be physically broken up by a larger and more developed root system, which lowers soil density and increases soil aeration.
Water infiltration: In addition to enhancing soil structure, biofertilizers can also increase water penetration. Water helps to soften compacted soil layers so that plant roots may more easily break them up when it permeates the soil more effectively.
Decomposition of organic matter: Some biofertilizers contain microbes that quicken the soil’s organic matter decomposition. As organic matter decomposes, it helps to create humus, which enhances soil structure and lessens compaction.
