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 run off 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 run off 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. The Keyline refers to topographic feature linked to water flow. This allows the water run off to run directly into an existing water channel, and prevent soil erosion caused by the water.
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 prevents 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.
6. Cover Crops/ Crop Rotation – Cover crops such as turnips and radishes are rotated with cash crops in order to blanket the soil all year- round and produces green manure the replenishes nitrogen and other critical nutrients. Using cover crops can also suppress weeds.
7. Soil Conservation Farming – A mixture of farming methods intending the mimic the biology of virgin land. These practices can be used to prevent erosion and even restore damaged soil and encourage plant growth. Eliminating the use of nitrogen fertilizer and fungicides can increase yields and protect crops from drought and flooding.
8. Agrostological Measures – Planting grass in heavily eroded areas is called an agrostological measure. Ley farming practices cultivating grass in rotation with regular crops to increase the nutrient level in the soils. When the grass is harvested it can be used as fodder for cattle. For heavily eroded soil it is recommended to grown grass for many years to let the soils naturally repair themselves.
9. No till farming – This is the method of growing crops year round without changing the topography of the soil by tilling or contouring. This technique increases the amount of water that penetrates the soil and can increase organic matter of the soil which leads to larger yields.
10. Green Manures – Green manures are a few different crops that can be grown, not for produce or food usage, but grown in order to fertilize the farm land on which it grows. This method can improve the soil structure and suppresses the growth of weeds.
11. Salinity Management – When water evaporates from the soil, it leaves behind its salt. This can lead to damage of the soil and nutrient loss. Using humic acids can prevent this or growing crops like saltbush can rejuvenate the soils and replace lost nutrients. High levels of salt in the soil can often be caused by changes made to the water table by damming and other causes.
12. Stream Bank Protection – During floods, stream banks can often cave in. Preventing this by constructing walls along the banks or plant useful tree species will prevent this in the future and prevent soil loss down the stream.
