Studies on the prevention of salinization of peat soils Ali Rıza DEMIRKIRAN Kahramanmaras Sutcu Imam University, Agricultural Faculty, Soil Science, Kahramanmaras, Turkey, 46100 Contact e-mail: ademirkiran@ksu.edu.tr, ademirkiran2000@yahoo.ca The addition of organic matter, such as peat, intends to optimize the production of plants, including crops, flowers, and young tree saplings and to maintaining soil fertility. It is also important to prevent soil salinization and high soil pH levels in the soil. Peat organic matters have been used as nutrient sources since ancient times; and the use of organic matter also contributes to good soil till and structure, but many peat soils have salts and it can cause salinization. Different materials and methods can be used to minimize the risk of salinization. Our invention seeks to provide a multi-step process in which the quality of peats and their effifcient application to farmland is maximized, so that peat organic matter will be provide as much benefit as can reasonably be achieved for the farmland. 10
Evaluating the ability of hyper accumulator plants for the reclamation of salt affected soils A. M. EL-GHAMRY*, A. A. MOSA, A., G. A. K. REHAM Soils Dept., Faculty of Agriculture, Mansoura University, Egypt Reclamation of salt affected soils requires huge amounts of water for alleviation of soil salinity, but the problem is the supplies of good-quality water are falling short of demand for intensive irrigated agriculture in many arid and semi-arid regions. The judicious selection of salt tolerant plants, which are able to grow successfully on saline soils to remove enough amounts of salts to reduce salinity may improve or bring easily such soils under cultivation, among these plants kochia and barnyard grass could be ideal plants. For this purpose two pot experiments were conducted at the experimental greenhouse of the Faculty of Agriculture, Mansoura University, Egypt, to estimate the ability of kochia (Kochia scoparia) and barnyard grass (Echinochloa crusgalli) on salt affected soils reclamation. Soil salinity was decreased after cultivation of kochia and barnyard grass under both clayey and sandy soil conditions, and kochia was more efficient in decreasing soil salinity as compared with barnyard grass. Soluble cations (Na + , K + , Ca ++ , and Mg ++ ), and anions (CO 3 - , Cl - , and SO 4 = ) were decreased after cultivation of kochia and barnyard grass under clayey and sandy soils, whereas (HCO 3 - ) anions were increased. Nutrients concentration in kochia and barnyard grass were varied according to soil salinity in both soil types, and it is cleared that concentrations of N, P, K, Ca and Mg were decreased, whereas Na was increased.
