    agriculture on the soil is erosion. Though erosion is a natural process that occurs through the movement of soil by water, wind, and gravity, intensive farming acts as a catalyst. The manner in which industrial agriculture is performed makes the farmland more susceptible to erosion. Over-plowing the land removes the protective layer of plants and decaying organic matter whose root systems hold the soil in place. Soil erosion becomes problematic as a result of the slowness of soil formation. Because

    clay are of extreme importance in soil science. Plant growth, and hence crop production, within any environmental condition is largely controlled by soil structure which results from reactions involving clay. The active clay material in .soil, particularly in combination with small amounts of organic matter, exerts a tremendous effect on soil properties. This effect may be on structure (the arrangement of soil particles), or on consistence (the response of the soil to mechanical manipulation). Where

    about experiments conducted to test the responses of plants to different soil origins and different types of competition then that which is normal for the plant. It focuses on the grass species of Bouteloua and the shrub species of Elaeagnus. The research conducted for this study found that competitive responses may be affected by factors such as soil type and in turn that plants affect the resources in their soils and in their soil community. In the studies researched not many studies viewed these effects

    The soil sample I chose for this report is a piece of land I rented two years ago. On the land, I ran three one acre inbred increases and a seven acre isolation plot for Pannar Seeds. I chose this particular field because of the degree of flatness it has in certain parts of it. In order for the yield results of the 1,250 different inbreds to be accurate, it was extremely important that the isolation plot was placed on level ground and all the same soil type. The field has a total of 114 acres it

    productivity through the rise in groundwater close to the soil surface, and also where the water table rises above the surface. The raised water table results in the soils becoming waterlogged and air spaces in the soil are filled with water, and plant roots, in effect, suffocate from the lack of oxygen, limiting plant growth in those areas. Where does it occur? Waterlogging occurs where bad irrigation methods are used and in poorly drained soils where water can't penetrate deeply. For example, there
