Product Description

Product name: Manganese Sulphate Monohydrate 31.8%min powder form
Chemical formula: MnSO4H2O
CAS: 10034-96-5
Molecular weight: 169.019
Product performance: Manganese is the forming element of some enzymes participates in animal's metabolism of protein, carbohydrate as well as lipid. Manganese is also a anticipant informing of skeleton. When lack of this element, animals will occur slowly growth, thick and their skeletons are misshapen, enginery is abnormal and newborns animal will be ataxic.
Description: It is mainly used as nutritional additives in animal feed and fertilizer in agriculture. It is also used in synthetic fiber industry, preservative, material of printing and dyeing and be used in medical for fungicide and emetic, and in electroplate, water purifiction etc.

    This review paper critically assesses the literature on soil-microbe-plant interactions influencing availability of

micronutrients in the rhizosphere. The emphasis is placed on Zn and Mn, but Fe is also covered to some extent.

Micronutrient availability in the rhizosphere is controlled by soil and plant properties, and interactions of roots

with microorganisms and the surrounding soil. Plants exude a variety of organic compounds (carboxylate

anions, phenolics, carbohydrates, amino acids, enzymes, etc.) and inorganic ions (protons, phosphate, etc.) to

change chemistry and biology of the rhizosphere and increase micronutrient availability. Increased availability

may result from solubilization and mobilization by short-chain organic acid anions, amino acids and other

low-molecular-weight organic compounds. Acidification of the rhizosphere soil increases mobilization of

micronutrients (eg. for Zn, 100-fold increase in solubility for each unit of pH decrease).

For diffusion-supplied micronutrients, the uptake rate is governed by the soil nutrient supply. Fertilisation with

micronutrients (more so in case of Zn than Fe) can be effective in increasing the concentration of micronutrients

at the soil-root interface. In addition, micronutrient-efficient crops and genotypes can increase an available

nutrient fraction and hence increase micronutrient uptake.

Our understanding of the physiological processes governing exudation and the soil-plant-microbe interactions in

the rhizosphere is currently inadequate, especially in terms of spatial and temporal variability in root exudation

as well as the fate and effectiveness of organic and inorganic compounds in increasing availability of soil

micronutrients and undesirable trace elements. The interactions between microorganisms and plants at the soilroot

interface are particularly important as well obscure.
