Methods and Techniques of Soil Conservation
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.
13. Earthworms – Earthworms provide great benefits of farm land due to the way they burrow under the ground and provide more are for water to rest after it has infiltrated the soil. When these worms excrete egesta, this sits in the soils and gives the crops many nutrients which are absorbed via the roots of the plants. Earthworm casts contain a vast amount more nutrients than any natural soil in the world, and for that reason should be invited into the soils of farmland to help prevent erosion and will lead to larger crop yields.
14. Mineralization – To help crops reach higher yields or full potential, sometimes crushed rock or chemical supplements are added to the farmland, this helps combat mineral depletion. Normally used after flooding, it brings substantial amounts of sediment which can damage the nutrient level of the soil.

Methods of Soil Conservation
1. Contour Plowing:
- Plowing along the contour of the land helps in reducing soil erosion by preventing water from flowing downhill.
- This method helps in retaining soil moisture and nutrients.
2. Terracing:
- Terracing involves creating steps on steep slopes to reduce the speed of water runoff and prevent soil erosion.
- This method also helps in conserving water and improving soil fertility.
3. Windbreaks:
- Windbreaks are rows of trees or shrubs planted along the edges of fields to reduce the impact of wind erosion.
- They help in stabilizing the soil and preventing the loss of topsoil.
4. Crop Rotation:
- Crop rotation involves planting different crops in a specific sequence on the same piece of land.
- This method helps in maintaining soil fertility, reducing soil erosion, and controlling pests and diseases.
5. Agroforestry:
- Agroforestry involves integrating trees and shrubs into agricultural landscapes.
- Trees help in reducing soil erosion, improving soil structure, and providing additional income through the sale of timber and fruits.
6. Conservation Tillage:
- Conservation tillage involves minimizing soil disturbance during planting and cultivation.
- This method helps in reducing soil erosion, preserving soil moisture, and improving soil health.
By implementing these methods of soil conservation, we can protect our valuable soil resources, maintain soil fertility, and ensure sustainable agricultural practices for future generations.
