چکیده

In agricultural lands, high nutrient levels of nitrogen, phosphorus and potassium are very important due to the high need of plants. By improving the nutrient content of sodium soils, the fertility and growth of the plants improve. Accordingly, in order to investigate the effect of underground drainage on soil quality in Khuzestan region, this experiment was carried out in a completely randomized block design with four replications at three depths (0-30) and (30-60) cm in south of Khuzestan province in the Albaneem area of Shadegan city. Research on two plots of land, one with underground drainage and the other without drainage. After full operation, it was observed that the salinity (EC) at depths (0-30) and (30-60 cm) in the drainage area was less than the drainage area, so that the difference was significant at a probability level of 1% Two areas show. Nitrogen, phosphorus, potassium were not affected by underground drainage and sampling depth, and their value did not show significant differences.
