**4.4 Role of legume vegetation on enhancing soil physical properties**

Important soil physical properties are bulk density, porosity, combination stability, and texture. These properties are additionally associated with waterrelated methods including aeration, runoff, erosion, water maintaining capacity, and infiltration rate [15]. Legume vegetation have a manageable to enhance physical properties of soil by being a soil conditioner and enhancing the physical residences [16]. Leguminous cover crops have a tremendous effect on soil physical properties broadly speaking due to the manufacturing ability of large biomass which affords substrata for soil organic undertaking and soil organic matter [17]. Furthermore, leguminous cover vegetation are grown to protect the soil from loss of plant nutrients and erosion, while green manure plants are grown for the motive of improving soil bodily properties. Moreover, some plants can physically modify the types of soil profile. Legumes additionally have an effect on soil shape by means of their impact on aggregation. Leguminous cover crops can expand or keep an appropriate soil C/N ratio and increase in preserving soil organic carbon stock. Legume plants often result in higher infiltration of water, due to direct effects of the crop residue in soil formation and aggregation [18–26].
