Though these organisms form only a fraction (less than one percent) of the total soil mass, but they play important role in supporting plant communities on the earth surface. The Importance of Soil texture for Agriculture Soils are often described in terms of texture and structure. Soil is the layer of the Earth's surface that has been changed by physical or biological processes. The five soil-forming factors that control the process of change are parent material, climate, topography, biota (plants and animals) and time.Soils are grouped into categories according to their observed properties. For farmers in an agroecosystem context the are 3 components to consider in terms of why soil biology is important; the natural processes themselves (soil engineering, litter transformation and micro-food web participation), the impact of management on these processes, and the combined effect of the first two on plant performance. The U.S. Department of Agriculture’s classification system consists of six categories.

If the moisture content of a soil is optimum for plant growth, plants can readily absorb soil water. The soil profile is an important tool in nutrient management. While studying the scope and importance of […] Soils science is essential to understanding the conditions that affect and support life on Earth: Without it we wouldn´t be able to grow plants, which are used as food for both humans and animals. Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil fertility. In soil science, hydrology and agricultural sciences, water content has an important role for groundwater recharge, agriculture and soil chemistry. As the soil weathers and/or organic matter decomposes, the profile of the soil changes. Soil is also responsible for maintaining natural and artificial vegetation. While there are … Environmental variables can determine the pH balance and nutrient content of soil. Clay-sized soil particles fit together in a way that creates small pores; however, overall there are more pores present. Soil supports foundations of buildings, roads and communication infrastructures. Emphasis continues to grow on the importance of soil sustainability. Soil pH Importance – Soil pH influences the solubility of various mineral elements causing their accumulation in forms more or less available for plants, as well as their leaching to deeper layers. Soil structure and texture is very important when it comes to cultivating crops.Important factors to note are: 1 . You have to know what are the differences between Soil texture and Soil structure because mis understanding of these word learners get into groggy; Simply say that Soil texture is proportion of Sand, Clay and Slit.. In each type, you just take some soil and mix it with the water or any other buffer solution offered by the soil testers and then tested. Plants are the basis of life because they are the primary producers which means, life on earth would be impossible without the soil. A proper soil test will help to determine the application of fertilizer needed to meet the crops’ requirements while also taking advantage of the nutrients already present in the soil, thus being a very cost effective tool for managing a fertilizer program. As a result, these plants produce important needs … Soil texture refers to the relative quantities of inorganic matter and this is related to soil texture, which is indicative of such macro properties as infiltration rate and water holding capacity. In an era where the population continues to grow rapidly, the agricultural sector is being put under increasing pressure to respond and produce enough food for our growing society. Soils science is essential to understanding the conditions that affect and support life on Earth: NIFA supports activities aimed at understanding and managing the impact of soils on the environment and agricultural productivity. As world population and food production demands rise, keeping our soil healthy and productive is of paramount importance. The right soil composition allows roots to perform their function properly.
