Effect of soil applications of magnesium sulfate and

The effect of two different sources of magnesium fertilization, Epsom salt (MgSO4·7H2O) or dolomite (MgCO3·CaCO3), on enzymatic discoloration, phenolic, crude lipid, phospholipid and Mg content, of Katahdin potatoes was studied over a 3 yr. period. Tubers grown in soils receiving either Epsom salt, or dolomite, were compared with control tubers receiving no added magnesium. Tubers from

The Dolomite Problem Discover Magazine

1996-2-1  In general, geologists had thought that sulfate inhibits dolomite formation because negatively charged sulfate ions tend to tie up positively charged magnesium ions in water, leaving them less available for making dolomite. Magnesium is the key ingredient that distinguishes dolomite from other calcium carbonate minerals, such as limestone.

Magnesium vs Dolomite What's the difference? WikiDiff

As nouns the difference between magnesium and dolomite is that magnesium is a light, flammable, silvery metal, and a chemical element (symbol mg) with an atomic number of 12 while dolomite is (mineral) a saline evaporite consisting of a mixed calcium and magnesium carbonate, with the chemical formula ca]]mg(c[[oxygen|o 3) 2; it also exists as the rock dolostone.

Carbonate, Halide, Sulfate, and Sulfide Minerals Doner

This chapter discusses the kinds of carbonate, sulfate, and halide minerals commonly found in arid and semiarid soils. The most common Calcium (Ca) and magnesium (Mg) carbonate minerals in soil are calcite, Mg-calcite, dolomite, and occasionally aragonite. Carbonate accumulation in soil can block pores and restrict movement of water and air.

A model for calcium, magnesium and sulfate in seawater

A theoretical model has been constructed for calculating the concentrations of dissolved calcium, magnesium and sulfate in seawater over the past 550 million years (Phanerozoic time). It is demonstrated that the weathering of Ca carbonates and silicates by carbonic acid can be generally ignored in the modeling. A previous model of the carbon cycle is used to guide input to the oceans of Mg
