what can Ultra do for my crops?AgriGro Ultra Analysis Block 300

When Ultra® is applied as part of a good management program, this bio-stimulant keeps your plants, and the immediate soil environment, "spiked up" with the nutrition and growth supplements they require to maximize yield and minimize plant stress.


Agri-Gro Ultra® simply helps a plant to reach its genetic yield potential by boosting plant growth, increasing nutrient uptake, strengthening the plants' natural defense system and building a healthy, disease suppressive growing environment. Research has proven that crops treated with Ultra® are healthier and experience less disease pressure, have improved nutrient availability, establish larger root systems, grow stronger stalks and produce higher yields.


In a detailed University study, the ingredients in Agri-Gro Ultra® significantly increased the uptake and availability of 12 macro- and micro-nutrients while lowering the levels of sodium in the soil and plant tissue.


what's in Ultra?

Agri-Gro Ultra contains bio-stimulants, nutrients and other organic materials that not only stimulate biological life to increase nutrient availability and uptake. Containing complex carbohydrates, plant essential macro- and micro-nutrients, a proprietary blend of beneficial enzymes, amino acids and a host of naturally occurring plant and soil stimulants not found in ordinary fertilizers, Ultra has been shown to have a profound effect on both the plant and soil microbial environments.


how should I use Ultra?

Agri-Gro Ultra is a liquid concentrate and should be diluted for best results. We recommend mixing Agri-Gro Ultra in with your regular planting solution or foliar sprays. Use Agri-Gro Ultra to reduce nutrient tie-up caused by soil nutrient imbalance. Ultra can help to sustain a plant's natural System Acquired Resistance (SAR) which is often damaged by environmental conditions and chemical fertilizers. It can be applied along with your other foliar fertilizers. Agri-Gro Ultra can also be used to help stimulate microbial activity. Check with your certifier before using.


The products we offer are designed to be used together as part of a full-year nutritional program. For more information on use, application rates and timing, contact Agriculture Solutions today.
