Reduced vegetative cover negatively affects soil health, because vegetation maintains soil structure, contributes to soil organic matter, and prevents erosion. Yan et al. Farmers are responsible for maintaining a majority of the cropland vegetation in arable regions of the world. Vegetation (or the lack of it) is a key factor affecting weather patterns and micro-climates.

[ 36 ] studied the environmental impacts of shelter forests, and suggested that suitable tree species and plant density need to be considered. Soil moisture under vegetation cover was higher than that of bare soil at GPG (p > 0.05) (Fig 2, Table 1).

Vegetation is a general term for the plant life of a region; it refers to the ground cover provided by plants, and is, by far, the most abundant biotic element of the biosphere. This might be explained by the fact that bare soils tend to dry out faster due to the higher solar energy they receive. Gravimetric water content of the soil was affected by soil texture, vegetation cover, and irrigation treatment . These studies illustrated that vegetation can consume amounts of soil moisture and cause soil drying. 2.3.2 Soil pH. The following factors are affected by vegetation: Figure C. Bradford pear orchard. Soil moisture not only can affect root-feeding herbivores directly through physiology but can also affect them through changes in pH. Sandy soils hold about 101.6 mm (4 in) of available water within the depth of root penetration about 1.22 m (48 in), loams and clay loams 152.4 to 177.8 mm (6 to7 in), and clays about 203.2 m (8 in). Many scholars have proposed the principle of moderate VC for the management of sandy land. Differences in the ability of different soil types to store water do exist. Through evaporation, transpiration, and the uptake and storage of carbon, healthy soils and appropriate vegetation moderate the climate of the world and provide a breathable atmosphere. In order to investigate the factors affecting soil moisture, various environmental data were collected from a humid forest hillslope in this study. In February and June, prior to the initiation of summer wet and dry irrigation treatments, there were no differences in soil moisture between irrigation treatments (p > 0.1). How does this relate to agriculture? soil moisture dynamics with depth are different in behavior. Effect of Soil texture on water Storage and Water Movement. This phenomenon is also suggested by other dryland studies . For example, soil moisture content could change the concentration of minerals or substances in the water and cause shifts in pH as soil wets and dries. The distribution of soil moisture along a hillslope is related to the spatial distribution of the soil properties, the topography, the soil depth, and the vegetation.
