MULTAN (APP): Agriculture experts have advised farmers to employ proper techniques to bring saline or water logged areas under cultivation of crops to improve agriculture production. In a press statement issued here Friday, agriculture spokesman said that saline land covered by white material on surface usually contains greater quantity of soluble minerals and this drawback can be addressed simply by water application after two to three times deep ploughing. However, for this to happen, the land must be porous and ground water level should at least be six feet. The minerals, being soluble, get dissolved in water and move deep down the soil.
Such fields should be kept under crop cultivation ceaselessly to avoid chances of accumulation of minerals again. The saline land having white and black material or only black material on surface needed different kind of treatment tomake it cultivable. Such soils also contain Sodium in addition to soluble minerals, are hard to undergo ploughing and resist water absorption. Gypsum or any other compound is utilized to separate Sodium from soil.
Application of Gypsum followed by water triggers a chemical reaction and brings soluble Calcium that separates Sodium from soil and then replaces it to make soil softer.
In addition to this treatment, botanical fertilizers should also be applied and suitable crops be selected for better results.
Animals waste fertilizers or green fertilizers can be applied. For green fertilizers, farmers should grow fodder and then plough it before flower stage and bury it in the soil for
Farmers should select the crops which can demonstrate resistance against salinity at the time of germination and per acre application of seeds should 25 per cent more than the
normal for better results, the release concluded.
