Chelated Manganese EDTA Fertilizer 13% Mn

Manganese deficiency and iron deficiency look almost the same, so test before you treat. Greenway Biotech Chelated Manganese EDTA is a water-soluble powder guaranteeing 13% manganese, all of it held by EDTA, for preventing and correcting a confirmed manganese shortage.

The manufacturer’s directions for this 13% manganese EDTA run 4 to 12 lb per acre on vegetable and field crops and 4 to 15 lb on trees and vines, broadcast or metered through drip, sprinkler or furrow irrigation. They also cover individual trees by trunk diameter, buffered foliar sprays and professional turf use. Growers can also weigh it into hydroponic recipes.

Deficiency is most common on high-pH, sandy, peat and organic soils, and in cold, wet or dry spells. Too much manganese can bring on iron deficiency, so start at the low end. It supplies manganese only and does not lower pH. Packaged in Madera, California in 1, 2, 5 and 25 lb sizes.
