Soil comes in various forms Soil conservation is the best way to make sure that we have the land we need to live on. Erosion is the biggest enemy of soil and land conservation. Protecting / conserving soil with grass, plants or mulch is needed. Always make sure that the soil on your property stays right where it should be! Soil pH levels change to crop growth Soil pH levels determine what plant will grow Soil pH levels can be changed by acid rain or soil contamination from acids or bases. Soil pH levels can be changed by mulch. The role of soil pH is to control nutrient availability to vegetation. There are six different macro-nutrients: Calcium Phosphorus Nitrogen Potassium Magnesium Sulfur A pH level of 7 is neutral - for most plant is pH neutral soil is perfect. When you hear about alkaline soils, the pH level is 7.7 up to 9. Soil below a pH level of 6.5 is called acid or sour. Calcium, magnesium and potassium are usually made available to plants via cation exchange surfaces of organic material and clay soil surface particles - it is necessary for the estimation of soils to consider the dependencies between soil structure, hydraulic properties and the cation exchange as well as transport processes. Acidification increases the initial availability of these cations. Residual soil moisture concentrations of nutrient cations can fall to low levels after initial nutrient uptake. Soil pH levels don't directly show if nutrient are available - complex combination of soil types, soil moisture regimes and meteorological factors play a significant role. The important observation is that pH is the regulatory mechanism to plant nutrient uptake, and that the theoretical concentration of soil nutrients is meaningless until pH levels are in the optimum range for uptake. We can raise soil pH with lime and liming soil. To lower the pH of an alkaline soil we can add sulfur, iron sulfate or aluminium sulfate. Another way is to apply urea, urea phosphate, ammonium nitrate, ammonium phosphates, ammonium sulfate and monopotassium phosphate to reduce soil pH. Soil is made up of something called parent material - the basic stuff needed to make soil. Changes in temperature help to make soil. When it is hot, rocks can get bigger, they expand in size. When it turns cold, rocks shrink. Often rocks cannot handle this shrinking and expanding, they crack and break up into small pieces that break into even smaller pieces. together with other particles they turn into soil. Rain and ice can also get into rocks and break them apart. Ice in a rock crack is very powerful - it can break a rock easily. In Nature, water seeps gently into the ground as vegetation breaks the fall. Soil acts like a sponge and feeds wells, feeds small creeks, building rivers. ![]() But scraping off the natural protection of our earth, changed water seepage very much. Faster water runoff, more erosion, and more floods are the answer to men's destructive behavior. "Responsibility is born when the love for others grows stronger than the love for yourself." Peter Bonenberger A good soil has different levels. They're named O, A, B, and C. O is the top level. It's about an inch thick made up of dead stuff that breaks down and keeps the soil "O"-so healthy. The A horizon is topsoil that's alive with roots, tiny microstuff like bacteria and fungi, and all kinds of critters. Number three is horizon B. Plants and animals have a tough time getting through B, because usually it's very hard. Level C has less living stuff in it than O, A, and B. C is parent material that's made up of the rock and soil that formed the three layers above it. Soils comes in many colors: black, red, yellow, white, brown, and gray. When water gets into the soil, it pours into pores. Pores are spaces in the soil that come in different sizes. The bigger the pore, the more water it holds. Air gets down into the soil through the same pores that let in and hold water. Most of all plants need soil, soil is for them the way to eat and drink. Soil has a lot of the things that plants need to satisfy their appetites. Plants need nutrients - many different ones. Roots drain water from the soil. That keeps the soil from staying too wet. Root stabilize the soil, can hold it together. Roots help make soil splitting rocks into pieces that later become soil. When it comes to making more soil - a lot of time is needed. It can take 100 years to form one-inch of soil. We need to protect our soil cover, we need to protect our forests, our grass covered prairies when we want to protecting our food supplies. Conservation of soil in the agricultural sector is essential since soil is necessary for the growth of plants and crops. Loss of top soil through erosion and a rise in salinity due to overuse of chemical fertilizers and pesticides has made matters serious. Shelter belts of trees and bushes along the edge of agricultural fields slow down the wind speed = wind erosion and reduce evaporation. Planting of trees, grass, and bushes breaks the force of rain and helps to keep soil in place. Contour farming can be use in hilly areas and in lowland areas for paddy fields. Farmers recognize the efficiency of contour-based systems for conserving soil and water for many centuries.
If you are a responsible human,soil conservation is one of your tasks. Simple things contribute to soil conservation: We all can make a difference! For more information send us an email ask for advice.. |
