ProRelease Fertilizer Benefits
Controlled Release Fertilizers (CRF) are granulated fertilizers designed to be applied directly to the root zone of the crop. Utilizing poly-sulfur coating technologies, CRFs slowly and predictably release fertilizer over time, continuously feeding for months with only a single application! This allows for unprecedented ease of use and control for professional growers.
The coated prills of ProRelease Field will not wash away under heavy rainfall and are the best option for introducing critical plant nutrients to your crop when the soil is very wet or saturated (if used as directed). Think of ProRelease Field as an excellent insurance policy against the elements, ensuring consistent nutrition in the root zone.
The use of ProRelease Field will allow prolonged feeding from a single application, reducing labor and application costs from repeated applications of water soluble or liquid products. Simply apply the fertilizer to your field, plant, and you’re done.
General Hydroponics' usage recommendations are based on the most current university research and our own internal research. Work conducted by Hawthorne R&D has laid the foundation for the use of CRF technology and they are confident that ProRelease Field’s formulation and use rates are in line with how your crops grow.
How to Use
For field grown medicinal herbs, General Hydroponics suggests evaluating rates between 110 to 130 lb N per acre for a 12 week crop planted at a density of approximately 2,000 plants/acre.*
ProRelease can be used alone or in conjunction with a liquid fertilizer or other granular fertilizers. It can be broadcast, banded in row or incorporated into the soil using either method.
For banding applications, place the band off to the side of the planted plant, preferably below the soil surface. Do not place the band immediately below a planted seed or rooted cutting. For broadcast applications, it is ideal to incorporate the product into the top 1-3 inches of soil. Spread fertilizer evenly on the surface and incorporate.
*These rates are based on published university recommendations. Rates should be adjusted based on soil needs, planting density, climate, crop, media, irrigation or rainfall amount and especially other nutrient usages.
