Mekong fertilizer with soil improvement alum

In alkaline soil contains many Fe, Al, sulfur (S) in different forms, including forms toxic to plants such as sulfide, sulfite, sulfate ... Thus the alkaline soil should not be applied to sulfur-containing fertilizers.

     Symptoms of poisoning alum iron rice: purple leaves, the leaves appear brown spots dotted tiny iron alum root, if slightly, the roots of rice will be slightly yellow and white. But seriously, there will be golden brown. If more severe, the entire roots will turn black and floppy, short roots and root hairs have fallen off smoking. When determining the field leaks alum should take measures such as discharge and handling of water, phosphate fertilizer, lime, fertilizer products that contain calcium.

     With traditional farming methods beat grooves to drain rice fields and associated alkaline phosphate fertilizer lining, lime, fertilizer products that contain calcium are correct measures and very effective. However, in order to discharge alum good economic drain system should be designed as follows: A trench drain alum with a depth of about 1 to 1.2 m wide by 1.5 - 2 m and is connected to economic power. This ditch also work to help the transportation division, seed, harvest the product is very convenient.

     At the same time, to exploit the acidic paddy soil to be effective, need to incorporate measures such as:

    - The system of canals for sure, you or a discharge of acidic water at the right time.

    - Increased use of fertilizer, organic fertilizer, high volume distribution containing CaO, MgO.

    - Cultivation of resistant varieties of alum as: OM3536, OM2395, MTL392, MTL500, HD 1, U.S. $ 95-20 ...

     On the other hand, to improve soil acidity can use organic fertilizers, most of multi-element distribution, in order to raise pH, acidity decreased rapidly and provides calcium for plants and other ingredients which are divided Fertilizer can be combined with the toxic iron, aluminum making them become inactive, no longer harmful.

     Currently on the market specialized products for the alkaline soil CORPORATION AGRICULTURAL MEKONG that her children can be found in most of the agents as: Meko-Sica with the content of CaO, MgO high-feature " HIGH SPEED LOW Phen, Organic Decontamination powerful, balanced diet "from 20-25kg/1000m2 doses, fields can be applied heavier than alum 30-40kg/1000m2, use fertilizer before sowing or completion of a liner 1, phase 2, or can be used as soil acidity or leaks of organic MEKONG exclusively used for rice-A01,-A04 MEKONG for all crops.

     I wish you to be effective in cultivating their land!
