Go to Step 4, If it is slightly sticky, slightly hard to squeeze and forms a medium (2-5cm) ribbon, it is a type of CLAY LOAM. Soil Consistence: Soil consistence is the resistance of a soil to deformation or rupture and is determined by the cohesive and adhesive properties of the soil mass. Slightly Sticky – soil adheres to both fingers but comes off of one rather cleanly Sticky – soil adheres to both fingers and tends to stretch somewhat then pull apart . However, you can amend or alter the soil to produce a richer soil … The black soil is very retentive of moisture. Silt has a much smoother texture than sand, but retains some of clays characteristics in its ability to mold. Angular and subangular: Blocky peds are imperfect cubes, 5–50 mm, angular have sharp edges, subangular have rounded edges. Suitable Crops: It is suitable for growing groundnuts, pulses, millet… Clay soil is defined as soil that comprised of very fine mineral particles and not much organic material.
