How Can Termites Improve Soil Fertility?
Termites are known to have an important influence on the soil ecosystem. They modify water infiltration rates and increase the amount of organic matter in the soil, which leads to increased plant growth. In addition, they recycle nutrients from wood and other plant materials. This reduces the amount of humus that forms in the soil and reduces the risk of crop failure.
Termites can also help restore barren soils. They contribute to the regeneration of crusted soils by generating tunnels that increase the water infiltration of the soil. They also increase the macroporosity of the soil.
Termite mounds are enriched in clay, cations, and exchangeable cations. They can act as hot spots for nutrients in the ecosystem. The presence of bacteria in the termite mound soil may help to boost the health of the soil. These microorganisms can be used as biofertilizers and antimicrobials.
During rainy seasons, termites collect nutrients from the air. These nutrients become temporarily immobilized in their biomass. In dry tropical forests, they feed on aboveground litter. In African savannas, termite mounds can cover 25-75% of the total soil surface area. In agro-ecosystems, termites can consume dung, lichen, and organic amendments.
Depending on the size and shape of the mound, termites can improve soil fertility. The amount of clay present in the mound can help explain higher water retention. In addition, termite galleries can increase the depth of water infiltration.
Studies indicate that termite mounds contain large numbers of free-living bacteria. These bacteria have been found to support beneficial soil bacteria. In addition, these bacteria can be used as biofertilizers, which can enhance the growth of crops.
