ZeoliteNa2Al2Si3O10·2H2O Nanoporous CAS Number : 1318-02-1
Enhances fast and sustained growth Reduces irrigation by up to 35% Holds nitrogen and other nutrients in the growth zone Increases infiltration and porosity Increases aeration
The ability of BRZ™ to hold ammonium and its high potash content, low sodium content, and ability to hold water make BRZ™ an excellent soil amendment for golf courses, sport fields, parks, common areas, lawns, gardens, all sandy soils, and agricultural applications.
Soil salinity problems are generally in semiarid or arid areas where there is not enough meteoric water to leach salts from the root zone of the plants.
Saline-sodic soils behave differently than sodic soils and have different reclamation procedures.
A saline soil is one in which there is an excess of soluble salts of calcium, magnesium, potassium, and sodium. They are generally sulfates, bicarbonates, or chlorides.
Saline soils are a result of irrigating with high salinity water, a lowering water table that fails to leach the salts, surface migration of salts through a combination of capillary action and osmotic pressure from underlying saline deposits or soils, and evaporation of saline water bodies.
When the concentration of salts in the soil solution equals or exceeds the osmotic concentration in the plant cells, water uptake is stopped and water moves out of the cells to create plasmolysis or “burning.”
Plants are more sensitive to high salinity during their germination and seedling stages than during later stages when they develop some immunity.
Soil salinity measures all the ions in the soil (not just sodium), and it is measured by electrical conductivity (EC). The more the ions, the higher the salinity. It is measured in millimhos (mmhos) per centimeter or milliequivalents (meq) per centimeter. Some laboratories report it as milliequivalents per liter (me/l). Cations are measured as milligrams in the laboratory and converted to milliequivalents to put the cations on an equal basis. The EC values in mmhos/cm or ms/cm are interpreted as follows:
Below 2 No salinity problem2-4 Restricts growth of sensitive crops4-8 Restricts growth of many crops8-16 Restricts growth of all but salt tolerant cropsAbove 16 Only a few very tolerant crops make satisfactory yields.
Saline soils may be reclaimed by providing good percolation, drainage, and good quality water to leach the salts.
