Soil aggregation: Some biofertilizers contain microorganisms that make glue- and polysaccharide-like compounds that adhere to surfaces. These chemicals aid in the formation of aggregates by binding soil granules together. Larger pore pores produced by soils aggregates enable water to permeate and be retained in the soils as opposed to simply evaporating off the surface. Water is retained better thanks to the improved soil structure.
Mycorrhizal association and root growth: Some biofertilizers, such as mycorrhizal fungi, develop symbiotic connections with plant roots. This connection results in a broad and well-established root system. The surface area via which plants may collect water from the soil is increased by a deeper root system, enhancing overall water uptake and retention.
Some biofertilizers contain microorganisms that hasten the decomposition of organic matter in the soils, which is enhanced. As organic material decomposes, it helps to create humus, a stable part of soils organic matter. By enhancing the soil’s ability to store water and lowering water drainage, humus aids in soil moisture retention.
Drought tolerance: A plant’s capacity to withstand drought stress can be improved by using specific biofertilizers. They accomplish this by increasing the plant’s water-use effectiveness and modifying its physiology to make it more resilient to water scarcity. Biofertilizers indirectly increase soil water retention during times of water constraint by assisting plants in better water management.
