| Abstract | ||||
| Wide areas of severely deteriorated lands at Quaroun Lake shoreline have been left bare since a long time , although many attempts were made to cultivate some parts but all failed. A field experiment was carried out in a private field during the season 2014-2015 at the north of Fayoum Governorate (about 200 m from Quaroun Lake, Sinours District).Nine treatments were tested including the control, shallow and deep plowing ( 20 and 60 cm ), application of 50% and 100 % of estimated gypsum requirements and their combinations. Remarkable decreases were found in the values of soil bulk density, ECe values, soluble cations and anions, soil paste pH and removal sodium efficiency ( RSE). Values of total porosity, hydraulic conductivity, field capacity, permanent wilting point, available water increased with soil deep plowing and gypsum application. Also, grain and straw yields of grown wheat crop < br />were enhanced with soil deep plowing together with gypsum application and leaching with required amounts of water in comparison with those of the control treatment . Deep plowing with the application of 100 % of estimated gypsum requirements resulted in the best improvement of both soil characteristics and plant growth among all other treatments. Results of the present experiment that was conducted in a private farm has actually encouraged farmers of the studied area to start land reclamation and cultivation of their lands that were left bare since a long time. | ||||
