NPK Liquid Fertilizer to Stimulate Plant Growth

Our agronomists have studied the application of phosphorus more than any other nutrient. This key nutrient plays a role in almost every developmental process, and is particularly important in initial growth and fruit production. To optimize initial growth and stimulate the production of high-quality fruits, we developed our premier phosphorus fertilizer, that is partnered with nitrogen, potassium, and micronutrients for maximum performance, PrG.

PrG uses a blend of phosphate, nitrogen, potash, and iron to maximize crop response at critical growth stages. The combination of quick-release phosphates with slow-release, carbon-protected, polymer phosphates, promotes exceptional growth early on, and plants continue flourishing through reproductive stages.

Phosphorus is required for all stages of a tree or vine’s development, and PrG provides the nutrition needed for stable growth, budding, and fruit set. The nitrogen, potassium, and iron work synergistically with phosphorus to increase efficiency and nutrient uptake as the tree develops. This results in better nutrient uptake and distribution at fruiting.
PrG, through proprietary manufacturing technology, contains both ortho-phosphate and carbon-protected polymer phosphate to provide readily available and controlled-release phosphorus with minimal danger of tie-up in the soil. PrG’s phosphates are protected by Flavonol Polymer Technology. This technology allows for sustained nutrient extraction throughout the plant’s growth.

Our 9-24-3 fertilizer protects from leaf burn by using a gentler formula. Commodity fertilizer can put fruit trees and vines at risk of injury due to over-exposure to nutrients. PrG’s unique combination of long phosphorus chains and quick-release phosphate, lowers nutrient exposure while supplying a longer-lasting source of nutrition.

Flexible application also helps to protect plants and reduce manpower. PrG can be safely applied via broadcast, topdress, sidedress, as a foliar, or through fertigation. It can also be effectively mixed with other fertilizers, as well as pesticides and fungicides. This means you can give your orchard or vineyard optimal nutrition without requiring more time or energy.

Pro-Germinator is an 9-24-3 fertilizer designed to stimulate steady crop growth from seedling to reproductive phase. It is derived from ammonium nitrate, ammonium sulfate, urea, superphosphoric acid, potassium polyphosphate, and ferrous sulfate. The optimal use of Pro-Germinator depends on your crops, application, climate, soil, and other conditions. Talk to an agronomist to maximize the benefits of Pro-Germinator.

Have us design a custom nutrition plan for you

An AgroLiquid nutrition plan is dependent on your location, climate, soil conditions, and goals with your crop. All of our tailored programs start with reviewing your soil samples with one of our expert agronomists. After our analysis, our team will provide you with a couple options that will help you meet your goals on a budget that won’t break the bank.

AgroLiquid Scientific Advancements

Phosphorus is involved in almost every plant process, and it is especially important during active growth periods, such as fruiting. A steady supply of phosphorus helps to improve the quality of fruit and gives trees the nutrients they need through every growth phase. PrG is comprised of long-chain phosphorus to support a slow, steady release across the growth cycle, as well as phosphorus that can be immediately used. Combined with nitrogen, potassium and iron, this promotes optimal nutrient utilization.

Flavonol Polymer Technology

This bonds with your nutrients and creates a protective layer that makes up to 80% more of your nutrients available to plants. It sounds like magic, but it’s just science.
