General Information


BLACK LABEL Zn contains Humic Acids extracted from Leonardite ore. These humic acids are then combined with liquid plant nutrients in a patented reaction process.

BLACK LABEL Zn contains nitrogen, available phosphate, and humic acids.

BLACK LABEL Zn may be placed 1 to 2 inches below seeds or directly injected into root system because the product is non-phytotoxic.

BLACK LABEL Zn is designed for use in all soil types. It should be concentrated for maximum response. Apply it as a band in the soil or inject it through drip or micro-sprinkler systems. Application rates will vary depending on the crop grown.

BLACK LABEL Zn is an effective foliar nutrient when mid or late season phosphate levels fall below optimum values. Multiple applications may be beneficial.

Applications should be made at night or early in the morning. When used as directed this product does not supply all nutrients required by plants and is to supplement a soil fertility program based on soil tests.

Purpose Statement: To aid in plant development by increasing root availability of mineral nutrients and condition soil.

CAUTION: Always check compatibility with other products prior to use. Do not mix with conventional calcium based fertilizers. Black Label is not compatible with conventional products containing the salts of heavy metals.

NOTE: For all crops, the rate of water should be sufficient for thorough coverage. Coverage is dependent on proper droplet size, which is a function of nozzle size and pressure.

Limitations, Restrictions, and Exceptions


- Use 1 to 2 gallons per acre. Under deficient conditions a second application may be required 2 weeks later. Up to 4 gallons per acre may be applied. Apply with 10 to 20 gallons of water per acre.
