21. Indigenous Crops
The growth of indigenous crops is a good way to conserve soil, as the plants have a natural need for the nutrients in the soil in your area, they help to prevent soil erosion. If you grow nonindigenous crops a recommended tip is to plant indigenous crops around them, in order toAnswer:hope it helped just write little..... i wrote in detail.....follow me and mark me as brainliest
Explanation:
Soil Conservation is the name given to a handful of techniques aimed at preserving the soil.
Soil erosion removes the topsoil that is necessary for organic matter, nutrients, micro-organisms that are required for plants to grow and shine. Soil conservation is one such step that protects the soil from being washed away. There are several ways to conserve soil that can be done through agricultural practices or measures you take at home.
Many different techniques have been invented throughout the years with the aim of preserving the nutrient level of the soil and preventing erosion.
1. Contour Plowing
Originating in ancient Phoenicia, Contour Plowing involves plowing grooves into the desired farmland, then planting the crop furrows in the grooves and following the contours. It a very effective way for farmland on slopes to prevent runoff improve crop yields.
2. Terrace Farming
Terracing is a method of carving multiple, flat leveled areas into hills. Steps are formed by the terraces which are surrounded by a mud wall to prevent runoff and hold the soil nutrients in the beds.
More commonly found in lesser developed nations due to the difficulty of using mechanized farming equipment in the terraces. Very popular in Asia for planting rice.
3. Keyline Design
A more enhanced version of Contour Plowing, maximum water retention is achieved by taking into account all the watershed properties when making the contour lines.
4. Perimeter Runoff Control
This is the practice of planting trees, shrubs, and ground cover around the perimeter of your farmland which impedes surface flows and keeps nutrients in the farmed soil. Using the grass way is a specialized way of handling perimeter runoff that uses surface friction to channel and dissipate runoff.
5. Windbreaks
Rows of tall trees are used in dense patterns around the farmland and prevent wind erosion. Evergreen trees can provide year-round protection but deciduous trees can be adequate as long as foliage is apparent during the seasons when the soil is bare.
