While there are several types of salts in the soil, salts that have higher solubility in water are dissolved and removed from the soil,  But salts with low solubility in soil, sediment layers hard to cause clogging in the soil or in their coverage. Among the salts in soils of the arid and semi-arid areas, three compounds of calcium carbonate (with solubility of 0.013 gr/lit), magnesium carbonate (with solubility of 1.9 gr/lit) and calcium sulfate (with solubility of 2.5 gr/lit) salts, usually are found in these areas and have low solubility. Among the mentioned compounds, magnesium carbonate accumulation in soil is very low, while calcium carbonate and calcium sulfate salts concentration are found higher and can cause clogging by the sequential deposition. The amount of calcium carbonate in the soils of arid regions may reach up to 80 percent of soil weight. It provides the conditions for rapid deposition and a layer of rigid form and clogging the system (FAO, 1973). <br />This experiment was conducted in order to analyze the application of sugarcane bagasse in controlling the clogging of the agricultural sub-surface drain envelopes.
