Harp-N-Tek™ Enhanced Fertilizer Blends Improve Nutrient Uptake
It’s the exclusive Harpin Protein that makes Harp-N-Tek™ Enhanced Fertilizer blends supercharge the nutrient uptake in citrus, vegetables, tree fruit, and turf. Harpin Protein has been combined with traditional nutrient and micronutrient formulations, and the result is a new dimension in performance.
Harp-N-Tek turns on the plant’s growth and stress-defense systems, which enhances the plant’s ability to absorb and translocate the nutrients made immediately available in the formulation. More nutrient uptake is better because it means more vigorous cellular activity, growth, fruiting, and stress tolerance.
Harp-N-Tek Enhanced Fertilizer is available in three high-quality formulations.
Harp-N-Tek™ 18-18-18 is a balanced blend of fertilizer plus micronutrients designed to boost nutrient uptake in vegetable and fruit crops, including strawberries, tomatoes, peppers, lettuce, squash, melons, and peaches. Growers find that when they make Harp-N-Tek a part of their crop’s fertility program they get more marketable produce, fewer culls.
Harp-N-Tek™ 15-0-40 CitrusSet helps trees set, size, and retain a better crop, whether it’s oranges, grapefruit, lemons or limes. Use Harp-N-Tek 15-0-40 CitrusSet at early pre-bloom to increase vigor and set the crop. Use it post-bloom to improve sizing of the crop. Use it late summer to help the tree handle seasonal or crop management stresses and retain more citrus to harvest.
Harp-N-Tek™ 11-41-08 is a special formulation for turf that enhances nutrient uptake for stronger root systems, tillering, vigor, and growback.
