potassium supplying power of selected alkaline-calcareous soils in the north-west of iran
solution potassium (so-k) and exchangeable k (ex-k) extracted by nh4oac are the major sources of potassium used by plants, but initially non-exchangeable k (nex-k) can also contribute significantly to plant uptake. perennial ryegrass (lolium perenne, cv. roper) was successively planted in ten surface soil samples with different clay mineralogical composition belonging to five soil types to dete...
متن کاملMagnesium affected soils in Colombia
Abtract The Mg +2 accumulation on the exchange complex of soils to a very high saturation levels affect their chemical, physical and biological properties. Magnesium has some capacity to develop higher exchangeable sodium levels in clays and soil materials. Colombia has a large area of these soils, located mainly in the main rivers valleys and in the Caribbean Region. In the Cauca River Valley ...
متن کاملMagnesium: The Mighty Mineral with Multifaceted Benefits
The human body requires a steady and adequate supply of essential nutrients in order to maintain balance—or homeostasis—to continue operating as a finely tuned machine. Of these required nutrients, vitamins and minerals are foundational. They are the sparkplugs that make our metabolic engines run, working as cofactors for enzymes and participating in the process of energy production. One minera...

متن کاملCorrecting Magnesium Deficiency of Limes Grown on Calcareous Soils with Magnesium Nitrate1
Marcotted 'Persian' (Tahiti*) lime trees with severe magnesium deficiency were sprayed with magnesium nitrate at 3 concentrations (1.75, 3.50, and 5.25 pounds of MgO/100 gallons of water). Three applications were made between March and September, 1967. Most of the magne sium deficiency symptoms disappeared after 2 sprays. The trees were completely green after the third spray, regardless of the ...
