To test your soil, you need to take a look at it and feel it. Contents:Types of Soil Structures1. Because these soils are sandy and arid in composition, the soil is mostly unusable for agriculture. Land use changes from natural ecosystems into managed ecosystems may have deleterious effects on soil structure and quality. Different soils contain different structures and each structure gives us the properties of particular soil. Elsewhere, farmers have often made use of soil depth to characterize soil types in terms of their productivity (Desbiez et al., 2004; Ndaka et al., 2015).
