Table 3 provides the Mg content of the common Mg fertilizer sources. High solubility of a fertilizer under high rainfall conditions, however, may also affect the Mg availability through large losses occurring by Mg leaching. Sources Of Magnesium Fertilizer the effects include overly large leaves from excess nitrogen soft turgid leaves and tissues weak stems long internodes low resistance to some fungal pathogens lowered Therefore the cellulose cell walls (fibers) of plants must be broken down before they are digestible and in order for nutrients to be available for digestion.

On the other hand, plants require these nutrients in larger quantities than the “micronutrients” such as boron and molybdenum. A simulation of high rainfall by excessive irrigation of 20 mm per day over a period of 16 days to a water saturated soil revealed that the amount of Mg lost by leaching differed between the two Mg sources tested. It is an essential building block in chlorophyll development and protein synthesis.
