Dry and barren land certainly cannot be used as a medium for farming. This is because the causes of barren and dry land do not have enough nutrients and water because nutrients and water cannot be resisted by the soil. Many factors cause the land to become dry and barren. Dry soil, of course, lacks water. If the weather and climate do not support the benefits of high rainfall, artificial watering can be done. Water can be sprinkled to make water spread evenly. One effort to prevent erosion and at the same time, an effort to preserve nutrients is to inspect plant planting schedules so that substances that are useful for soil fertility will not be absorbed by only one type of plant. This is called crop rotation with the hydroseeding costs method.
One of the efforts we can do next is to contour farming. Contour farming is an agricultural technique that implements planting based on the contour lines of soil so that the plant’s silver system will be more solid and able to hold back the soil when it rains (read: the process of rain) is heavy. Contour farming techniques or making land contours are like making land traps so that the soil will not be easily washed away by the water when heavy rain falls. In Indonesia, contour farming has been widely introduced to farmers and many farmers have implemented this system. Contour farming is mainly applied to sustainable agriculture.
It is a mound that functions to hold something, like water, in place. Making pair dikes can also be used as an effort to overcome soil erosion. Every sloping land is required to have embankments that are in the same direction and also parallel to the contour of the land. With the existence of this embankment, the falling rainwater can be accommodated and seep into the soil thereby reducing the occurrence of Run-Off or surface flow. In the embankment area that was made, it would be nice if we plant tall trunked plants such as corn so that it is not too long inundated by water.
