Emitters Subsurface Distribution of Soil Moisture the Soil in Different Tissues

The climatic conditions of the main problem in increasing agricultural production and water resources are limited. These factors turning  more and more to the pressurized irrigation systems. Among these systems, subsurface drip irrigation. The design and proper management of these enterprises to reduce water loss and optimal use of water and soil nutrients, soil moisture distribution around the dropper knowing how to demand. Shape (diameter and depth of wet soil) and the wetting front in the soil on many factors including texture and layers of soil, soil homogeneity, intensity of water, soil moisture content, slope of the land and water volume depends. The study of the distribution of moisture in the loam and silt loam subsurface Emitters taken. The results showed that the moisture in the soil with loam, silty loam texture will appear later. And because of the shallow depth of the pipes in both the garden, the moisture in the soil surface appearance. According to soil texture and appearance of moisture on the soil surface is recommended depth will increase tubes.
