The land is one resource that is often used by humans. Planting plants, building houses, and even doing activities requires land. Apart from these things, can you name the other benefits of the land? There are several ways to do soil conservation that is usually done, namely the way that is done by utilizing plants in such a way that the soil can avoid rainwater and surface runoff using hydroseeding all the efforts made for soil fertility can be done very easily. The mechanical method is the method of conservation carried out by changing the physical shape of the soil. Must have heard terracing? That is one example of mechanical conservation of soil. One of the purposes of mechanical means is to reduce the flow of water flowing on the surface of the soil so that the soil carried by water is small. Mechanical conservation can be done in three ways; A terrace or swale is a part of the soil that is made rather high by cutting the slope so that it can block or reduce surface flow. Some types of terraces are a terrace, flat terrace, bench terrace, and terrace credit.
To accommodate water flowing on the ground. The sewer is assisted by a diversion channel (divider) to divert water to the sewer. The terrace channel serves to catch water on the slopes. The sewer is planted with grass like elephant grass so that it is not easily eroded. Controlling buildings are buildings that can hold or control the rate of erosion. Controlling buildings can be dam checks, absorption wells, lakes and recharge land. The last way is by chemical means. As the name suggests, you certainly know how to do this by giving chemicals to the ground. This chemical method is carried out to compact the soil structure. The soil structure needs to be compacted because dense soils have the possibility of smaller erosion. In addition, this chemical method also balances the organic content in the soil, because soils with an organic content of less than 2% are generally sensitive to erosion. One chemical method that is often done is to add lime to acidic soils.
