Micronutrients: Functions, Sources and Application Methods

Plants store iron as ferritin, a protein that encapsulates ferric iron. Under aerobic soil conditions, iron is largely insoluble as a constituent of oxides and hydroxides. Ferric iron tends to be tied up in organic chelates. Hence, the concentration of free iron in the soil solution is exceedingly low in many soils. Plants have mechanisms to

The decrease in Se concentration mainly reflected a dilution effect caused by a growth response to the S fertilization. No direct relationship was apparent between forage Se and S levels. This study showed that S fertilization of S-deficient, low-Se soils to increase forage production may increase the incidence of Se deficiency in animals.

In P. strombulifera plants, H 2 O 2 concentration was significantly increased in roots of Na 2 SO 4 and Na 2 SO 4 + NaCl-treated plants at moderate salinity (−1.9 MPa) in correlation with increased lipid peroxidation in the former.

A New Process For Sulfate Removal From Industrial Waters

In bench tests using wastewater from a metallurgical plant, sulfate concentrations were as low as 190 mg/L, compared to the original concentration of 29,100 mg/L (Table 3). All of the most stringent discharge limits for this application, except TDS and SC, were met.

Nitrates - EnviroAlternatives| Live Green

When the raw water sulfates are high, nitrates in the treated water can be significantly higher that the raw water. This can be compensated for when sizing the system. It is also best to use a standard anion resin when the system is monitored and/or the sulfate concentration is low. There are selective nitrate resins on the market.
