Which is a result of loss of top soil? check all that apply. 1 loss in soil fertility 2 loss in water 3 poor crop production 4 hardened soil surface 5 deposition of aggregate

The topsoil refers to the uppermost layer of the soil, in which all the plants develop. Topsoil is essential as it comprises all the nutrients, which the plants require in order to live. However, almost half of the planet has become devoid of the topsoil in the past 150 years.  

Soil erosion can be considered as a gradual process, which takes place spontaneously, however, it can also take place at an alarming rate, resulting in an extreme loss of topsoil. In supplementation to erosion, the quality of the soil can also be influenced by other features of agriculture. These comprise loss of soil composition, compaction, soil salinity, and nutrient degradation.  

Thus, the correct answers are options 1 and 3, that is, loss in soil fertility and poor crop production.
