Soil erosion risk assessment is an essential foundation for the planning and implementation of soil and water conservation projects. The commonality among existing studies is that they considered different indicators e. It is widely accepted that the vegetation and distribution of rainfall differs according to the different slope aspects such as sunny slope and shady slope and these attributes will accordingly influence the soil erosion. Thus, existing studies neglecting this indicator cannot reflect the soil erosion well.
Soil conservation is an important part of conservation cropping systems. There are many benefits for producers who choose to employ soil conservation practices on-farm. Many soils in Alabama have low levels of soil organic matter due to the warm climate, coarse-textured soils and intensive farming practices historically used in the state. Rebuilding soil health is important! Soil is a natural resource we must work to conserve for future generations.
Soil Conservation is a combination of practices used to protect the soil from degradation. First and foremost, soil conservation involves treating the soil as a living ecosystem. This means returning organic matter to the soil on a continual basis. Soil conservation can be compared to preventive maintenance on a car. Changing the oil and filter, and checking the hoses and spark plugs regularly will prevent major repairs or engine failure later. Similarly, practicing conservation now will preserve the quality of the soil for continued use.
Creating garden beds and landscapes that have active underground ecosystem of earthworms and microorganisms that keep plants healthy can be achieved using composted soil with organic materials that include micronutrients and minerals. Applying compost also provides an aerated, non-compacted base for plant roots to thrive and to absorb water and nutrients, which is key in ensuring plant health. Healthy plants mean better wildlife habitat. Conventional lawns and many ornamental exotic plants require an exorbitant amount of clean water to stay green. Choosing native plants that are adapted to regional rainfall and soil moisture content is a great way to conserve this precious resource. You can also collect water in rain barrels for use in the garden. In suburban and urban areas, much of the water that hits the landscape washes away down the storm drains, often carrying pollutants and soil with it.
PDF | Conservation of soil and water resources is important for sustainability of agriculture and environment. Soil and water resources are.
Soil conservation is the prevention of loss of the top most layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification , salinization or other chemical soil contamination. Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas. A sequel to the deforestation is typically large scale erosion , loss of soil nutrients and sometimes total desertification.
Limited natural resources are available on the planet under immense pressure due to the ever-increasing population and changing climate.
Soil and Water Conservation within the Watershed Management approach. Soil and water conservation are those activities at the local level which maintain or enhance the productive capacity of the land including soil, water and vegetation in areas prone to degradation through. These activities are to be selected and implemented according to the respective local conditions; i. Soil and water conservation is an integral part of Watershed Management. Although Watershed Management was formerly considered to be nearly synonymous with soil and water conservation, it goes far beyond it today, comprising a variety of further activities that attempt to improve the living conditions of the people living within the respective watershed e. Introducing soil and water conservation in the Gina River catchment may further the sustainable utilisation of natural resources for the benefit of local people as the overall goal of Watershed Management.
Though soil and water conservation SWC technologies have been adopted in Geshy subcatchment, their effects on soil quality were limitedly studied. The studied soils are characterized by low bulk density, slightly acidic with clay and clay loam texture. P at the bottom slope classes and terrace positions could be attributed to the erosion reduction and deposition effects of SWC measures. P deficient.
