The undesirable effects on the soil (loss of fertile top soil) have been observed mainly due to erosion by water. The soil surface with an appropriate cover helps improving the soil structure for which many agronomic soil conservation practices have been used. This paper integrates that why a simple grass cover has been recommended to cope with this inevitable issue. The grass structure, influence of the root zone, grass efficiency against runoff and soil loss, and grass application at different slope angles have been studied. This paper further review the different parameters which must be considered while protecting the soil against erosion including hill slope shapes, characteristics of different plant types, proper compaction, soil modification, and cost comparison of different soil protection techniques.
