Most ranches on high ground are very steep. Therefore, it is necessary to use a sustainable method for proper soil conservation. One of the already known agroforestry methods is. Planting plants instead of the embankment The technology involves the use of an array consisting of perennials or shrubs, fast-growing pea plants such as acacia and hemp, or some narrow-leaved grass with multiple stems, such as vetiver, planted along the level of sloping areas. This long plant, consisting of this and other similar plants, will effectively prevent soil erosion. And within the plots that are between the rows of 4-10 meters in the fields that agriculture can grow crops The width between the rows depends on the slope. The higher the slope of the fields, the narrowing of the plots between the rows is narrower.
Restrictions on the use of row crops, such as the common bean basket plants, are often difficult to locate and or produce seeds or other parts of the tree species that are adequate for row planting and maintenance. degree Another obstacle is the time and labor required to maintain the plants in level rows, such as occasional weeding, level row crop pruning. Planting new plants
The same applies to restrictions found from farmed agriculture using level rows composed of legumes. Or vetiver grass alone would use valuable space per production Which does not want the area to be wasted in vain Although these rows are useful and highly valuable in soil conservation. But there is one exception: The production of fresh leaves used to feed livestock from legumes and certain grasses during the rainy season, such as Napier grass.
Another useful reason to use agroforestry is the use of a row of legumes, namely, legume cultivation is a hybrid crop that provides low shade and yields food yields such as papaya, pineapple, rattan, jasmine. Wood and tea within that level A lot of these plants Is valuable for Local farmer It is also quite easy to provide and when the row is planted at level There are two benefits: For soil conservation And also produce produce that can be eaten and sold In order to conserve the soil to fill the space between local grasses, such as broom grass, which local flowering grass that the villagers prefer to collect for sale to the broom factory is one suitable type to plant. In level row for soil conservation
Overall, the narrow-leaved grass Legumes and legumes with multiple stems are best preserved on top of the soil, especially on the steepest slopes. And increased production volume
