California Proposition 65 WARNING: This product can expose you to chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm; for more information, visit www.P65Warnings.ca.gov.

Visible yellowing can resemble iron or magnesium deficiency, disease, or root stress, so confirm the problem before applying. Soil pH affects manganese availability and may need correction as part of the fertility plan. For liquid applications, dissolve the measured product with agitation, make a compatibility test before tank mixing, and follow crop-specific directions. Avoid inhaling the fine powder, prevent foliar drift, clean equipment after use, and store the sealed bag in a cool, dry location.

The bulk package is suited to repeated treatments and larger production areas where testing supports manganese use.

How Manganese Sulfate 31% Powder (50 lb) fits a fertility plan

• Supplies manganese for fertility programs where soil, water, tissue testing, or a well-supported diagnosis indicates a need.
• A nutrient-specific amendment allows more precise correction than adding another broad, complete fertilizer.
• The package size and dry or liquid format shown in the title can be matched to the application equipment and growing area.

Application guidance: Confirm that manganese availability is actually limiting before application; pH, root health, salinity, and overwatering can produce similar symptoms. Follow the label rate and placement method, measure carefully, and avoid repeated applications without retesting. Nutrient excess can interfere with uptake of other elements.

Compare related secondary and micronutrient fertilizers when building a complete program.
