Magnesium sulfate

Magnesium sulfate is an inorganic salt with the formula MgSO 4 (H 2 O) x where 0≤x≤7 It is often encountered as the heptahydrate sulphate mineral epsomite (MgSO 4 7H 2 O) commonly called Epsom salt The overall global annual usage in the mid-1970s of the monohydrate was 2 3 million tons of which the majority was used in agriculture Get price

Sulfates

Sulfate gives a bitter or medicinal taste to water if it exceeds a concentration of 250 mg/l This may make it unpleasant to drink the water High sulfate levels may also be corrosive for plumbing particularly copper piping In areas with high sulfate levels it is common to use corrosion resistant plumbing materials such as plastic pipe Get price

Iron Nutrition Management in Plants

IRON UPTAKE BY PLANTS Plants uptake iron in its oxidized forms Fe 2 + (ferrous form) or Fe 3+ (ferric form) Plants use various iron uptake mechanisms One of these is the chelation mechanism – the plant releases compounds called siderophores which bind iron and enhance its solubility This mechanism also involves bacteria Get price

Zinc uptake from ZnSO4 (aq) and Zn

The time-resolved X-ray fluorescence showed that plants absorbed ca 10-fold more Zn from ZnSO4 (aq) than from Zn-EDTA (aq) However the uptake velocity did not influence the amount of Zn in the stem It let furthermore appear that the plants were able to reduce the absorption of Zn from Zn-EDTA (aq) earlier than ZnSO4 (aq) Get price

Sulfur assimilation

Sulfate uptake by plants Sulfate is taken up by the roots that have high affinity The maximal sulfate uptake rate is generally already reached at sulfate levels of 0 1 mM and lower The uptake of sulfate by the roots and its transport to the shoot is strictly controlled and it appears to be one of the primary regulatory sites of sulfur assimilation Get price
