*7.2.2 Minimize soil compaction and erosion*

Compaction caused by heavy equipment or machinery is becoming a serious problem on many agricultural lands [30]. The addition of organic mulch materials can help to ease the problem of compaction. These materials prevent compaction due to heavy implements or machinery and from wind and water erosion. It can also reduce the compaction of soil, which can negatively affect the roots of crops, thereby reducing their growth and development. Some grasses and legumes have been used as organic mulch, which serves as the best example of living mulch on the slopes and reduces soil erosion by aggregating the soil particles by binding them into a complex unit.
