Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO 3. Sodium bisulfite is not a real compound, [ 2 ] but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions.
Deep soil mixing requires specialized auger mixing equipment. In order to apply this method in-situ and in deep soil, the oxidant must be pumped to the point of mixing using a kelly bar (a piece of earth drilling equipment), or appropriate piping to the place where the soil needs to be oxidized. The soil then has to be mixed by using mixing blades.
Iron minerals can active for dechlorination. These minerals use Fe 2+. Particular minerals that can be used include green rust, magnetite, pyrite, and glauconite. [6] The most reactive of the iron minerals are the iron sulfides and oxides. Pyrite, an iron sulfide, is able to dechlorinate carbon tetrachloride in suspension. [2]
The sodium adsorption ratio (SAR) is an irrigation water quality parameter used in the management of sodium-affected soils. It is an indicator of the suitability of water for use in agricultural irrigation , as determined from the concentrations of the main alkaline and earth alkaline cations present in the water.
These chemicals cleave the bonds between the cellulose and lignin components of the lignocellulose. A variety of sulfite/bisulfite salts are used, including sodium (Na +), calcium (Ca 2+), potassium (K +), magnesium (Mg 2+), and ammonium (NH 4 +). The lignin is converted to lignosulfonates, which are soluble and can be separated from the ...
The bisulfite ion (IUPAC-recommended nomenclature: hydrogensulfite) is the ion HSO − 3. Salts containing the HSO − 3 ion are also known as "sulfite lyes". [1] Sodium bisulfite is used interchangeably with sodium metabisulfite (Na 2 S 2 O 5). Sodium metabisulfite dissolves in water to give a solution of Na + HSO − 3. Na 2 S 2 O 5 + H 2 O ...
When dissolved sodium in comparison with dissolved calcium and magnesium is high in water, clay soil swells or undergoes dispersion which drastically reduces its infiltration capacity. [ 1 ] In the dispersed [ clarification needed ] soil structure , the plant roots are unable to spread deeper into the soil due to lack of moisture.
Tilling the soil, or tillage, is the breaking of soil, such as with a plough or harrow, to prepare the soil for new seeds. Tillage systems vary in intensity and disturbance. Conventional tillage is the most intense tillage system and disturbs the deepest level of soils. At least 30% of plant residue remains on the soil surface in conservation ...
