Soil is one of the three major natural resources, alongside air and water. It is one of the marvelous products of nature and without which there would be no life. Soil is made up in part of finely ground rock particles grouped according to size as sand and silt in addition to clay, organic material such as decomposed plant matter. There are basically three types of soil, each one has its features and nature. These are; Clay soil (Alkaline) particles are very small and compact. Gardens with these types of soil particles don't work well because the air has a hard time getting to the roots. Sandy soil particles arelarge. The water and nutrients (particularly nitrogen) quickly drain away from the plant root zone. Silt soil is made up of fine particles. Like clay the soil holds water but have good aeration around the root In this research we have studies and examined the plant growth inspecific area. The plant did not grow in that area. We analyzed the soil to understand the reasons. The results of the test show that the soil is Alkaline. It is a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer
