Maz-Zee S.A. International Penatron Soil Conditioner

(800) 775-6123

Penatron Soil Conditioner, which contains many interacting (synergistic) components, has helped increase potato yield and quality for the past 20 years in Idaho and other growing regions.

Penatron is much more than a wetting agent. Its components include enzymes and catalysts to stimulate soil microbial metabolism, natural desert plant-extract wetting agents to reduce water surface tension and cytokinins (growth hormones) to stimulate root growth for better water and nutrient uptake. It also contains colloidal minerals that provide plant nutrients, plant extracts that provide hormones and vitamins that reduce stress due to adverse-environmental growing conditions, and humic and fulvic acids to improve soil physical conditions.

Penatron reduces water use for less pumping expense, improves aeration with improved soil structure to help roots get vital oxygen, stimulates root growth to assist in water and nutrient uptake, increases the availability of soil nutrients, assists in better water infiltration to reduce runoff and erosion, stimulates soil microbial activity to build soil structure, provides essential plant nutrients and reduces clods and dirt at harvest.

Sym-Agro Employ and Myconate

Employ, a biochemical pesticide classified as a plant health regulator, is an entirely unique class of crop production technology. Employ is a highly effective and environmentally sound tool to improve yields and regulate overall plant health. HarpinAB, the active ingredient in Employ, is one of a class of proteins produced in nature by certain bacterial plant pathogens.

The harpin protein binds to a plant's early warning receptors, stimulating the plant to act. The plant responds by sending a signal throughout itself, initiating a sequence of physiological and biochemical reactions. This reaction activates both growth and stress-defense pathways within the plant. Employ can be applied through irrigation systems and is tank-mix compatible with most products.

Myconate is a water-based soil additive. Its unique mode of action is designed to stimulate the colonization of mycorrhizal fungi. Myconate contains a naturally occurring isoflavone called formononetin, a signaling molecule released by plant roots to trigger mycorrhizal spore germination and speed the development of mycorrhizal roots of crop plants.

Myconate increases growth and colonization of roots by beneficial vesicular-arbuscular mycorrhizal (VAM) fungi, which increases the ability of plants to absorb water and nutrients by increasing the effective absorbing surface area of root systems.

Great Salt Lake Minerals' Sulfate of Potash

(855) 313-3331

Sulfate of Potash, produced by Great Salt Lake Minerals Company, contains the most efficient balance of nutrients to optimize potato yields, quality and storability without a high-salt index and unwanted chloride. Sulfate of Potash is the richest source of low-chloride potassium, providing potassium content of 50 percent K2O and 17 percent sulfur as sulfate.

Research has shown that Sulfate of Potash increases specific gravity over Muriate of Potash, which contains 47 percent chloride. The high chloride level of Muriate of Potash impacts quality and storability. Because it contains only very low levels of chloride, Sulfate of Potash produces potatoes with higher specific gravity levels,, meaning more starch and less water in the harvested crop. That can lessen storage losses due to shrink significantly, and improve processing quality.

Sulfate of Potash is 17 percent sulfur, in readily available sulfate form.


Simplot Avail

(800) 331-6789

Developed in SFP laboratories, Avail has become known as "the most important fertilizer advancement in 30 years." By freeing your phosphorus fertilizer from fixation, Avail's patented technology keeps phosphorus ready and available to your crops when they need it, delivering increased fertilizer performance for optimal yield potential.

Avail phosphorus fertilizer enhancer lasts for an entire growing season, which means that from the time you put your phosphorus fertilizer in the ground, all the way to harvest, it is available to your crop-even when it is applied in the fall.

While the science behind Avail is complex, the idea is really very simple. Avail is a patented technology that surrounds phosphorus fertilizer in a water-soluble "shield." By blocking the bonds of attraction of chemical elements in the soil to the phosphorus, more is available for your crop to utilize.


Simplot NutriSphere-N

Simplot's NutriSphere-N works for you in three exclusive and important ways. First, it erases the effects of urease. Where urease typically encourages volatilization, NutriSphere-N controls urease, keeping it from robbing your nitrogen-or your yield potential.

Secondly, it calls a truce to bacterial warfare. Some soil bacteria work with enzymes to convert nitrogen fertilizer into nitrates that are prone to leaching and volatilization. Others don't. NutriSphere-N selectively inhibits unwanted chemical reactions without turning your growing fields into battle fields.

Lastly, it finds a stable relationship with the plant. Plants can do more with nitrogen in its ammonium form than they can with nitrates. It protects nitrogen in its ammonium state before it gets converted, giving the greatest return on nitrogen fertilizer investment.
