Summer is the right season for preparing autumn fertilizers. Recently, we Rech Chemical Co. Ltd receive a lot of water soluble manganese sulfate inquires from Shandong, Shanxi, Henan and other places.

It’s easy to see these places locate in Chinese typical manganese deficiency areas, central hilly region in Hubei, Hunan and others where the red soil grown from red sandstone and granite contains low manganese content; The northern plain near Shandong, Henan regions where the calcareous soil weight light with less organic matter but good soil permeability belongs to manganese deficiency soil.

Fertilizer absorption ability varies in different crops, like as wheat, to form 1 ton of dry matter, the wheat needs to absorb manganese 26g. Therefore, the fertilizer’s amount would be different, taking wheat for an example: 1. for the basal fertilization: manganese sulfate 1 kg for each 1/15 acre; 2. for seed manure: Stir manganese sulfate 4~6 grams with every kilo of seeds when treating. 3. for top dressing: In wheat seedling stage, jointing stage, flowering period or when plant appear manganese deficiency symptoms, spray with 0.1~0.2% manganese sulfate solution.
