Slope of The Land Toward The Hiding Horizontal
The greater the slope angle given the greater likelihood of erosion and landslides.
stability of agricultural land sloping areas and to reduce the rate of soil erosion, it would require the following steps.
1. Terracing, planting crops with system Ie terraces to prevent soil erosion.
2. Contour Finarmg, the land planted in contour lines, so that the roots can hold soil.
3. Dykes making partner (mound) to hold hasilm erosion.
4. Contour Plowing, the direction of the line plow Contur resulting horizontal grooves.
5. Contour Strip Cropping, the cultivation of land by dividing it by a narrow and elongated shape with a contour that squiggly shape. Each planted with different plant species in intermittent (intercropping).
6. Crop Rotation, the business turnover of plants so that the soil does not run out of one of the nutrients due to continued sucked by one kind of plant
7. Reforestation, replanting forests bare.
The erosion of the land will greatly affect the fertility of the soil for agriculture. The higher / greater the degree of surface soil erosion means that the infertile and unsuitable for agricultural food crops. Setting water (drainage) the land also affects the soil fertility conditions. If the water regulation ugly, then the land will be inundated parts of its surface.
Not all land on the earth's surface can be used directly by humans because there are certain constraints, such as the land covered thick ice at the poles and in the land of high mountains, arid soils with too high temperatures such lands in desert lands are not fertile, and fields consisting of rock, which are very difficult to process. Only land that is qualitatively very possible to be used in the fulfillment of human needs called the potential field.
Potential land that is in the earth's surface can be used by humans for nonagricultural among others in the form of:
1. Utilization for industrial sites.
2. Utilization for trade location.
3. Utilization for the locality.
4. Utilization of social facilities such as entertainment, infrastructure, transportation and other social facilities.
