Basically, soil conservation is to ensure that soil and water resources can support life in a sustainable manner. Soil conservation can protect the soil and water resources from being damaged (if the soil has been damaged), improve the soil so that it becomes productive again (Rehabilitation) and increase the productivity of the land which from the beginning was not / less productive land (Reclamation).
Soil conservation activities include controlling erosion, flooding, regulating water use, increasing land use, increasing production and farmers' income, including increasing integrated community participation and security activities. Priority for soil conservation activities using mechanical methods (civil engineering), such as frequent terracing, control structures, sediment and erosion retaining structures and others.
Why is soil conservation necessary?
Conservation is needed to regulate drainage and prevent erosion, especially in sloping areas, to prevent poor drainage which will interfere with root development and the availability of nutrients in the soil.
What are the types of soil conservation on oil palm land?
Types of soil conservation in oil palm land include making contour terraces, individual terraces, contour forts, rorak, and trenches.
What is meant by Mechanical soil conservation?
Mechanical soil conservation is all mechanical physical treatment that is given to the soil, and the construction of buildings aimed at reducing runoff and erosion and increasing soil gradeability. This soil conservation technique is also known as civil technical method.
What is the Soil Conservation Vegetative Method?

Soil conservation The vegetative method is a method of managing sloping land using plants as a means of conservation (Seloliman, 1997). In addition to preventing or controlling the danger of erosion, this ground cover plant can also function to improve soil structure, add soil organic matter, prevent the process of leaching nutrients and reduce soil temperature fluctuations. Conservation itself means an effort to conserve the environment but still pay attention to the benefits that can be obtained at that time by maintaining the existence of each environmental component for future use. Conservation can be done in almost all fields, for example nature conservation, animal conservation, plant conservation, forest conservation, river conservation, coastal conservation etc. Vegetative soil conservation techniques include: reforestation, agroforestry including alley cropping, strip cropping, grass strips, crop residues, ground cover crops, The application of cropping patterns includes crop rotation, intercropping, and relay cropping. Reforestation is carried out on critical lands caused by erosion, landslides, and human activities such as mining, shifting cultivation, and deforestation. |
