Texture is the relative proportion of the mineral components of soil: sand, silt and clay. This serves thefood requirements not only within the country but also in other parts of the world. With that said, I highly recommend that you begin the process of amending sandy soil using well-rotted manure or compost. However, the percentage of these can vary, resulting in more compound types of soil such as loamy sand, sandy clay, silty clay, etc. Thus, sandy soils will have high infiltration rates because pore sizes are larger and there are no finer materials to block the pores. Thus iron, clay, aluminum and organic compounds accumulate in this horizon [illuviation (opposite of eluviation)]. Your email address will not be published. It is subsurface layer reflecting chemical or physical alteration of parent material. The types of soil of a place are determined by climate, landscape, and vegetation of that place. The texture of the soil often changes with depth. the parent material in sedimentary deposits. The next layer has a lesser amount of humus but more of minerals. Sand is grainy and is not very good at absorbing water, so the soil is light and drains well. This soil has very good water storage qualities and making hard for moisture and air to penetrate into it. Sandy soils are highly permeable to water while clay soils have low to very low permeability. It has good water storage capabilities and is extremely sticky.4. 4.Loamy soil This soil consists of sand, silt and clay in relatively even concentration (40-40-20% concentration respectively).
