WebImproved soil structure Earthworm casts cement soil particles together in water-stable aggregates. These are able to store moisture without dispersing. Research has shown that earthworms which leave their casts on the soil surface rebuild topsoil. In favourable conditions they can bring up about 50 t/ha annually, enough to form a layer 5 mm deep. WebJan 12, 2024 · Soil is also greatly affected by rainfall. If it is too wet or too dry, nutrients in the soil can run off and not make it to the plants’ roots, leading to poor growth and overall health. Additionally, as mentioned previously, overwatering or too much rain can also lead to bacteria, fungus, and mold growth in the soil.

WebShrinking and swelling soils. Shrink–swell is the volume change that occurs as a result of changes in the moisture content of clay-rich soils. Swelling pressures can cause heave, or lifting of structures, whilst shrinkage can cause settlement or subsidence, which may be differential. This shrink–swell behaviour is the most damaging ... WebSoil is the loose surface material that covers most land. It consists of inorganic particles and organic matter. Soil provides the structural support to plants used in agriculture and is also their source of water and nutrients. Soils vary greatly in their chemical and physical properties. Processes such as leaching, weathering and microbial ...
WebSep 6, 2016 · Soil temperature is the function of heat flux in the soil as well as heat exchanges between the soil and atmosphere Elias et al. 5 It is also defined as the function of the internal energy of the soil (Ghali 2003). The transfer of heat in the soil Zhao et al. 6 and the latent heat exchanges at the surface Nwankwo et al. 7 are the primary causes of … Web14.1 Wind Erosion. Wind erosion is a serious environmental problem. It is in no way less severe than water erosion. High velocity winds strike the bare lands (having no cover), with increasing force. Fine, loose and light soil particles blown from the land surface are taken miles and miles away and thereby, causing a great damage to the crop ...
