Through a number of mechanisms that improve soil structure, increase the amount of organic matter in the soil, and promote root development, biofertilizers can have a favorable impact on the soil’s ability to hold water. The ability of a soil to store water for use by plants is referred to as its water-holding capacity. Here is how biofertilizers affect the soil’s ability to retain water:
Improved soil structure is a result of some biofertilizers, including mycorrhizal fungus and phosphate-solubilizing bacteria. Larger pore spaces between soil particles are produced by soil aggregation, which facilitates water infiltration and lowers surface runoff. Soils with better agglomeration can retain water for longer periods of time, reducing runoff and water loss.
Enhancement of organic matter: Biofertilizers can help the soil’s organic matter, such as crop leftovers and root exudates, break down. The formation results from the decomposition of organic materials.
Biofertilizers, in particular mycorrhizal fungi and certain bacteria that promote plant growth, boost root growth and development. A strong root system improves the soil’s capacity to absorb and hold water, which lowers water loss through leaching and enhances plant water availability.
Enhanced nutrient uptake: Biofertilizers make it easier for plants to get nutrients, which improves their general health and growth. Healthy plants are better able to use water effectively, which minimizes water loss and maximizes crop water use.
Some biofertilizers can aid in lessening soil compaction, which enhances water infiltration and retention. Because there are fewer pore spaces in compacted soils, there is more surface runoff and less water-holding capacity.
