Manganese (Mn) is a hard, gray metal that is frequently used in the production of steel. Workers may be harmed from exposure to manganese through the breathing of manganese fumes or dusts. Continued exposure can damage the lungs, liver, and kidneys. Exposure to manganese dust or fumes can also lead to a neurological condition called manganism.

Of all micronutrients, manganese tends to be the most common deficiency noted in soybean production. These deficiencies, however, usually respond positively to remedial treatments of manganese (when they are timely). As with all nutrients, yield responses are only attainable when manganese is deficient and therefore limiting yield. This Crop Insights describes manganese …
