Silt increase soil fertility due to its highly rich carbon, nutrients and animal excreta content. However, the shift away from traditional practices towards chemical fertilizers has meant that many farmers no longer use silt as a type of organic manure. The resulting increase in siltation in tanks and lakes thus reduced their water-holding capacities. However, with MJSA, both the purpose is being served. On one hand, the restoration works would increase the water holding capacities while on the other the silt being drawn out is benefiting the agricultural community at a larger level.
Silty and sandy soils are most prone to water erosion, particularly in areas with a high rainfall and where the ground slopes. Fields very susceptible to erosion commonly have shallow channels or rills, or even larger deeper gullies, after heavy rain. Surface water runoff happens when the intensity of rainfall is so great that all the water cannot soak into the soil. Livestock management can also affect the amount of soil erosion and runoff in grassland. Grazing with large numbers of stock in wet conditions can cause serious poaching of the soil and compaction in the topsoil which can lead to an increased risk of runoff.
Encyclopedic entry. Silt is a solid, dust-like sediment that water, ice, and wind transport and deposit. Silt is made up of rock and mineral particles that are larger than clay but smaller than sand.
Silty soil is usually more fertile than other types of soil, meaning it is good for growing crops. Silt promotes water retention and air circulation. Too much clay can make soil too stiff for plants to thrive. When there aren’t enough trees, rocks, or other materials to prevent erosion, silt can accumulate quickly.
