Recovery and management of saline soils cultivated under cover

The soils cultivated under cover deteriorate due to irrigation with saline waters, excessive fertilization, limited drainage and absence of leaching of salts by rain. The objectives of the work were to forecast leaching water depth, recover a salinized soil by hydro improvement method, maintain the...

description The soils cultivated under cover deteriorate due to irrigation with saline waters, excessive fertilization, limited drainage and absence of leaching of salts by rain. The objectives of the work were to forecast leaching water depth, recover a salinized soil by hydro improvement method, maintain the tolerable soil salinity by the lettuce crop applying the leaching requirement and evaluate the saline dynamics of the soil cultivated and irrigated with the Balansal model. In a greenhouse drain tubes were buried at 50 cm spaced every 2 m and 0.2 m3 tanks were installed at the discharge. The leaching water depth was predicted using 6 mathematical models and into basins of 10 m2, the initial and residual electrical conductivities of the soil and drained water were measured after applying 3 water depths, totalling 320 mm. The main results were: the predicted leaching water depth averaged 320 mm; the average initial soil salinity of 4.69 dS.m-1 was reduced to 0.81 dS.m-1 after the last leach; the salts decrease of the first leaching with respect to the initial salinity was 74.1%, that of the second leaching was 31% and that of the third leaching was 3.7%; the salinity of the drained water was 0.97 dS.m-1; 0.91 dS.m-1 and 0.88 dS.m-1 after each leach, respectively. With the application of a leaching requirement of 15%, the soil salinity was maintained at 0.87 dS.m-1 and the Balansal model predicted with good adjustment the saline dynamics of the soil during the crop cycle.
