Describe Some Methods Used to Protecting Land From Soil Degradation
Rotating crops inappropriately allowing the overgrazing of land frequent tilling and poorly organizing farmland can all lead to land degradation. The burning of forest results in soil erosion and gradual degradation of soil.
Soil Types How To Make The Most Of Them In 2022 Types Of Soil Soil Peat Soil
Rocks are piled up to slow down.
. All these have thus aggravated the problem of land degradation. They filter our water. Instead of applying chemical fertilizer for supplementing the nitrogen content of the soil we can use the natural process that involves the use of nitrogen-fixing bacteria in the legume root nodules.
Recharge of aquifers control and storage of water. The bare ground between plants is covered with a layer of organic matter like straw. Degradation of land can be controlled by adopting following measures.
These actions prevent optimal soil structure and health by reducing vegetation and not giviing soil the proper nutrients. Prevention of erosion in the first place by careful selection of land use practices. Agriculture Soil Degradation The Conscious Challenge.
Flood control by government initiatives. Due to the fact that some land has only had minor disturbances and other land has. Contour ploughing cultivation against the direction of the wind.
Stones grass soil are used to build barriers along contours. There are differences among these biological practices in relation to their mechanisms of restoration of agricultural land. In addition to this the use of organic forms of fertilizers such as cow dung.
How Is Land Degradation Prevented. Use of Early Maturing Varieties. Agriculture technologies for preventing soil degradation.
This type of farming is usually practiced across the hill side and is useful in collecting and diverting the run off to avoid erosion. And give ways of conserving and protecting the soil for future generations. You can do this successfully by planting three trees for every one that is cut down for the forestry industry.
Some methods normally adopted for soil conservation are listed below. Installing drainage systems to wash salts down the soil profile this method is expensive and complicated. The best possible way to help prevent environmental degradation is to give back to the environment.
Organic farming or green manures. Compaction sealing increased surface runoff and soil erosion decrease water infiltration for the recomposition of aquifers. Crop rotations agro-forestry reduced tillage cover crops vegetative filter strips residue canopy cover management and no-till are important among these Lamb Erskine Parrotta 2005.
Use of salt tolerant plants halophytes as bioremediants. It helps to retain soil moisture. Some common methods of soil conservation are explained below.
Strip cultivation cultivation in strips. The conversion of natural ecosystems to pasture land doesnt damage the land initially as much as crop production but this change in usage can lead to high rates of erosion and loss of topsoil and nutrients. Explain with causes and control measures Land degradation is defined as the reduction or loss of the biological or economic productivity and complexity of rainfed cropland irrigated cropland or range pasture forest or woodlands resulting from natural processes land uses or other human activities.
Armoring of channels with rocks tyres concrete timber etc to prevent bank erosion. Overgrazing can reduce ground cover enabling erosion and compaction of the land by wind and rain. Terracing and Contour Bunding.
When it comes to the planets trees you can never have enough. Control of Land Degradation. Our soils support 95 percent of all food production and by 2060 our soils will be asked to give us as much food as we have consumed in the last 500 years.
This lesson you should be. Wind breaks in land. By restoring forests and grass cover soil erosion and flood can be checked.
Objectives identify the factors causing soil degradation. Leaching out saline soils by applying water to contaminated soils to wash salts beyond the root zone. Land conservation is the process of protecting natural land and returning developed land to its natural state.
Ploughing into clod sizes too big to be eroded or ploughing into ridges. Ploughing the Land in Right Direction. 1 2 describe the advocacies of the organizations involving soil At the end of this lesson 2 3 involving soil conservation.
Water purification assimilation and recycling of pollutants. The use of wind breaks to modify wind action. Trenches are made in front of the barriers to collect water.
Agriculture Soil Degradation. Soil erosion and infertility are caused by a number of negative farming practices. Reclamation of bad lands.
They are one of our most cost-effective reservoirs for sequestering carbon. This usually checks or reduces the velocity of run off so that soil support vegetation. Like trees at borders.
Some methods used to restore saline soils are. These include slash-and-burn farming methods which destroy natural vegetation and inevitably strip entire ecosystems of fertile soil as well as other unsustainable farming methods that use improper chemicals additives and even irrigation materials to cause irreconcilable soil damage.
