Soil erosion is a major environmental issue because it can lead to water pollution. It has a huge effect on your soil's capacity to store nutrients. Agricultural soil scientists develop methods that will improve the use of soil and increase the production of food and fiber crops. By adjusting your soils pH, texture and fertility to your liking plants, you can create the good soil. Emphasis continues to grow on the importance of soil sustainability. Soil texture and agricultural contaminants. When soil erosion is severe, soil erodes faster than it can be renewed. Monitoring of soil health. The texture of a soil determines soil characteristics that affect plant growth. Soil structure affects the rate that water and air can move through the soil, root penetration, and the availability of nutrients to plants. As well it governs water flows. topography and soil, abiotic factors affecting crop growth, development and productivity The abiotic factors that affect plant growth and development include topography, soil, and climatic factors. Soil texture refers to the relative percentage of sand, silt and clay in a soil. It is also one of the most important factors in determining crop yields. They are the nonliving components of the environment which, along with the biotic or living factors, determine the extent in which the genetically-dictated characters are expressed in the plant. Soil Porosity and Permeability • Porosity is the total amount of pore space in the soil (30 to 60%) – Affects the storage of air and water – Affects the rate of movement of air and water • Permeability is the ease in which water, air, and plant roots move through the soil – Ease of air, water and root movement – Affects rate of water intake and drainage Soil texture class is a result commonly reported by soil testing labs and displayed on soils maps. Soil texture describes the proportion of the soil particles and the fineness or coarseness of a soil. Policymakers and national institutions responsible for the environment need tools and methods to check the effects of agricultural practices. Soil texture is an important part of understandng your soil. Correcting soil pH to a more favourable pH range will increase the availability of essential nutrients. Texture is an important soil characteristic because it will partly determine water intake rates (absorption), water storage in the soil, and the ease of tillage operation, aeration status etc. Natural soils are comprised of soil particles of varying sizes. smallest size soil particle. Most agriculture activities, especially on sloping landscapes, increase the potential for soil erosion. Your plants will find what your pH of soils should be. Evaluation of a good soil depends on what is being done with it and where it is located. When it comes to the end, making a good soil is more important for the crop production. 2. Three of these characteristics are water-holding capacity, permeability, and soil workability. You can not change your soil texture but happily organic matter can help with any difficulties. But did you know that soil erosion also can seriously impair crop productivity?
