Measures of land and soil quality should also account for differences in scale, both spatial and temporal (Halvorson, Smith, and Papendick, 1997). Scale variation is important because soil quality changes over time 6.2. Winter wheat yields and soil composition. To get over the problem of Ca and Mg in most soils the American publication referred to previously suggests that, in the ideal soil, the base cations should be 80% Ca + Mg, 5% K, 1% Na while the other cations would be 8% H, 6% other (presumably mainly aluminium (Al)).The soil pH would be about 6.5 with 8% H.Soil has the ability to remove or add dissolved ions such as potassium to the water, and store the ions as mineral nutrients that can be used later as nutrition of plants. What are the two main geochemical processes in soil? Soils are important is so many ways. The bottom line is that soil is essential for life because it provides the medium for plant growth, acts a filtration system for surface water, maintains the balance of atmospheric gases, stores carbon, and is a habitat for several organisms. Here are the detailed reasons rendering the soil important. Soil stores carbon mainly in the form of organic matter, and is the second largest carbon pool on Earth, after the oceans. The more organic matter there is in soil, the better a carbon sink it can be. A well-managed soil can thus be an important buff er against cli-mate change. Diff erent types of soil have diff erent carbon storage capacities. There are some factors that affect cation exchange capacity of the soil as follows: (i) Soil pH - The cation exchange in most soils increases with soil pH. The C.E.C. of a soil is relatively lower than at high pH. In most cases, the C.E.C. is determined at a pH of 7.0.Why is soil so important? Why is soil important?

It takes hundreds of years to develop just a few millimetres of soil, yet it can be eroded at an instance in a flash flood. Therefore we are now seeing this important resource being degraded at an alarming rate. The textural class of a soil is determined by the percentage of sand, silt, and clay. Soils can be classified as one of four major textural classes: (1) sands; (2) silts; (3) loams; and (4) clays. In this fact sheet, we will discuss the importance of soil texture, different methods to determine soil texture, and the importance of texture on capacity of a soil to function must be assessed before a soil's fitness for use can be measured (Mausbach, 1997). Measures of land and soil quality should also account for differences in scale, both spatial and temporal (Halvorson, Smith, and Papendick, 1997). Scale variation is important because soil quality changes over timeFigure 3. Eroded soil muddies runoff water after a spring thunderstorm in China. Soils are at risk of erosion when directly exposed to the impacts of raindrops and runoff. Surface erosion reduces the overall ability of soil to absorb and retain water.
