It is intended for correcting a confirmed manganese deficiency in field crops, orchards, vineyards, greenhouse production, or other large planting areas. Manganese supports chlorophyll formation, enzyme activity, and nitrogen metabolism, but excessive application can create nutrient imbalances.\u003c\/p\u003e\u003ch3\u003eApplication Options\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBroadcast: 20–60 lb per acre before or at planting.\u003c\/li\u003e\n\u003cli\u003eBand or side-dress: 10–30 lb per acre.\u003c\/li\u003e\n\u003cli\u003eFoliar: 1–3 lb per acre on actively growing plants before full leaf expansion.\u003c\/li\u003e\n\u003cli\u003eCompatible with appropriate fertigation programs when fully dissolved.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBase the rate on a current soil or tissue test, follow crop-specific guidance, and verify compatibility before tank mixing.

Soil pH strongly affects manganese availability: high-pH soils can limit uptake even when total manganese is present. Correct the underlying pH or drainage issue when appropriate and use manganese sulfate only at a rate supported by analysis and local crop guidance.\u003c\/p\u003e\u003ch3\u003eMixing and Handling\u003c\/h3\u003e\u003cp\u003eAdd the measured powder slowly to water with agitation, confirm that it dissolves, and make a small compatibility test before combining it with other inputs. Do not mix concentrates directly. Clean application equipment after use, prevent drift during foliar application, and wear the protective equipment specified on the label and SDS.\u003c\/p\u003e","brand":"Grow Organic","offers":[{"title":"Default Title","offer_id":21543452049521,"sku":"F1676","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0061\/1391\/9089\/files\/F1676_Manganese_Sulphate_edited.jpg?v=1766094761","url":"https:\/\/www.groworganic.mom\/products\/manganese-sulfate-tecmangam-powder-50-lb","provider":"Grow Organic","version":"1.0","type":"link"}
