Post-Harvest Foliar Nutrients

Post Harvest Foliar Nutrients Zinc Boron

As harvest season comes to an end, many growers and PCA’s are preparing post-harvest nutrient applications.  Now is one of the most important times to address the nutritional needs of plants- so that next year’s bloom and crop has everything it needs from the very start.

The important nutrients for this time of year are Phosphorous, Potassium, Zinc, and Boron.  Nutrient Technologies, Inc. has 2 products that are important components for most post-harvest applications: Tech-SprayTM Hi-K and Tech-GroTM B-17 Boric Acid SprayTM.

Tech-SprayTM Hi-K 0-26-28 is a water-soluble liquid concentrate that is a combination of Phosphate and Potash derived only from phosphate sources.  Many growers find the inclusion of Phosphate with their Potassium source to be ideal.  Phosphorous is essential for fall root development and an important energy source as trees come out of dormancy next season.  Potassium is very active in plant-water relations and aids in drought and freeze resistance.

Tech-GroTM B-17 Boric Acid SprayTM has been shown to supply the most effective, safest form of Boron for plants.  Including Boron in post-harvest programs has many benefits, particularly in spring health of floral parts including pollen tubules.

Zinc is another important nutrient to apply post-harvest, especially in deciduous trees.  Depending on your specific needs, we have 3 zinc containing products that are often recommended: Tech-Flo® Beta, Tech-Flo® CVN Zinc 10%, or Tech-Flo® Zeta Zinc 22%. Ask your PCA or review our product guide to determine the best products to include in your post-harvest program.  You can also download our free mobile app for instant nutrient help in the field.

Don’t forget- what you apply now will determine your bud break and fruit set next spring.
