Plant Catalyst 

Whether you’re a small home gardener, greenhouse grower, or run a large farm that feeds the world, PlantCatalyst® will provide a boost to your yield, profits, and the sustainability of your operation. For more than 40 years, growers have been using PlantCatalyst® to reduce the use of chemical fertilizers, enhance seed germination, substantially increase yield, and maximize profits.    


PlantCatalyst®: A Natural Plant Growth Alternative

Invented more than 40 years ago by award winning chemist, Dr. John W. Willard (PhD Purdue University), PlantCatalyst® is a water additive that boosts a plant’s ability to more fully absorb and utilize nutrients.  This proprietary blend improves the uptake and assimilation of nutrients into plant cells so that they can devote more energy to growing and flourishing.

When used as directed PlantCatalyst® will help the plants better utilize the nutrients and water in the soil and/or whatever growing medium is being used.  Not typically used as a complete nutrient replacement regimen, PlantCatalyst® will allow growers to maximize their nutrient regimen and significantly reduce the need to add more fertilizers and other nutrients.  As a result, growers can significantly reduce the amount of fertilizer and other nutrients needed saving time and money, while boosting crop growth and yield.

In this way, PlantCatalyst® provides farmers and gardeners alike with a safe, natural and completely non-toxic way to increase yields while limiting the amount of nitrogen-based fertilizer needed, keeping your wallet fuller and the planet safer at the same time.

How Does PlantCatalyst® Work?

As a catalyst, PlantCatalyst® is specifically formulated to work with water to enhance a plant’s ability to utilize fertilizer and absorb nutrients more efficiently. The patented formula works to alter the molecular structure of water to create “micelles” chains that are the special ingredient for encouraging the growth of healthy, productive plants.

In fact, decades of careful research and documentation has revealed that PlantCatalyst® helps plants better absorb and utilize the micronutrients found in soil and fertilizers while improving their water intake to increase resilience during droughts.

When used regularly on your crops, PlantCatalyst® will provide:

  • Bigger, healthier, greener plants
  • Earlier, longer lasting blooms
  • Thicker, more robust root systems
  • Stronger resilience against stressful growing conditions
  • Greater yields per plant

Reviewing the Research

PlantCatalyst® has over four decades of testing in universities, laboratories, commercial greenhouses, respected, publishable journals, large, multi-thousand acre farms, and backyard gardens.

The first evidence of PlantCatalyst’s effectiveness came from greenhouse grower Dean Sime who owned a greenhouse in Rapid City, South Dakota and was a good friend of the product’s inventor, Dr. John Willard.  At the urging of Dr. Willard, Mr. Sime began adding PlantCatalyst® to the reservoirs in his greenhouse and over several years began to refine how best to use the PlantCatalyst® to enhance germination, growth and yield.

Mr. Sime’s testing has been replicated by customers and researchers thousands of times in the decades following his first trials.  Research has been conducted in small gardens, commercial farming operations, greenhouses and virtually everywhere in between.We can confidently claim that research has been conducted on more than 100,000 plants worldwide in places as diverse as Zambia, Mozambique, South Korea, Canada and, of course, the United States.

A sample of some of the more comprehensive studies conducted on PlantCatalyst® over the years follows. Actual copies of the studies themselves are available upon request.

Zambia Agriculture Research Institute (ZARI)

The Zambia Agriculture Research Institute (ZARI) is a division of the Zambia Ministry of Agriculture and one of the most respected research institutions in Africa. During the 2016/2017 and 2017/2018 growing seasons ZARI scientists conducted a number of field trials using PlantCatalyst® on maize, cotton, soybeans, tobacco and groundnuts. The goal of the trials was to test the efficacy of PlantCatalyst, explore fertilizer reduction levels vs yield, and determine how using PlantCatalyst® can affect a farmer’s revenue. ZARI scientists used several different fertilizer reduction plots and explored effects of PlantCatalyst® when added to full rate fertilizer, 2/3 rate fertilizer, 1/2 rate fertilizer and no fertilizer at all. They measured variables such as crop germination, growth rate, leaf count, fruit/pod development, yield and profit margins. They found that PlantCatalyst® performed best when fertilizer is reduced by 50% and this combination was cheaper than full rate fertilizer, even when labor was included. Using PlantCatalyst®, as compared to the “typical” fertilizer regimen, also led to greater yields and, most importantly, substantial increases in profit per hectare. A quick Powerpoint synopsis of ZARI’s findings can be found here. You can read the full 2016/2017 report here and the full 2017/2018 report here.

American Journal of Plant Nutrition and Fertilization Technology

In a three year study conducted in greenhouse and laboratory settings, Dr. R. Neil Reese sought to examine the effect PlantCatalyst® can have on reducing nutrients without sacrificing yield. Dr. Reese examined the effects of PlantCatalyst® in a greenhouse setting over three successive grow cycles and also conducted controlled germination trials in laboratory grow boxes. Dr. Reese found that adding PlantCatalyst® to the nutrient regimen enhances plant strength out of germination, speeds up growth, and significantly increases yield. He studied lettuce, tomatoes, bell peppers and jalapeño peppers and adding PlantCatalyst® increased yield on lettuce by 13%, tomatoes by 24%, bell peppers by 46% and jalapeños by 52%. Dr. Reeses’ findings were published in the July 2016 issue of the peer reviewed scientific journal American Journal of Plant Nutrition and Fertilization Technology. You can read the full publication here.

Mozambique field trials

A central part of our PlantCatalyst® expansion plans involves working with international development agencies to help small holder farmers increase profits and yield. Mozambique is one of the poorest nations in the world and we’ve partnered with a number of international agencies to test the viability of using PlantCatalyst® in Mozambique.

The trials below were conducted by partners ETG Worldwide, administering a grant from the United Kingdom’s Department for International Development, and international development non-profit Food for the Hungry. In both trials, farmers used handheld sprayers to apply the PlantCatalyst® to their crops on a weekly or bi-weekly basis. All of the plots using PlantCatalyst® substantially outperformed the control plots with PC treated crops showing better germination rates, faster growth, more leaves/pods/fruits per plant, and far greater yields than the control crops.

iDE Zambia small farmer field trials, 2016/2017 growing season

During the 2016/2017 the international development non-profit iDE, conducted a series of research projects in Zambia to determine the feasibility and effectiveness of using PlantCatalyst® to help Zambian farmers increase profit per hectare.  iDE tested a number of plots in the Southern, Central and Lusaka provinces in Zambia on the two most prominent crops in those regions, soya beans and cowpeas.  The farmers used handheld sprayers to apply the PlantCatalyst® to their crops on a weekly basis and the treated fields received no more than 50% of the typical fertilizer regimen vs full fertilizer for the control crops.  All of the plots using PlantCatalyst® substantially outperformed those using full rate fertilizer with PC treated crops showing better germination rates, faster growth, more leaves/pods/fruits per plant, and far greater yields than the control crops.  All of this despite the fact that the PC treated crops had only HALF of the fertilizer!  In conclusion they found that PlantCatalyst® is cheaper than fertilizer which reduces up front costs for farmers and leads to greater yields on the back end which means farmers using PlantCatalyst® could expect to see an increase in profit per hectare simply by using PlantCatalyst.

Dr. Al Knauf, Former Adjunct Professor, Texas Woman’s University

Some of the most comprehensive studies on the PlantCatalyst® were performed by Dr. Al Knauf, A Biology Professor at Texas Women’s University. Dr. Knauf conducted both laboratory and field trials over a period of several years and his research was instrumental in determining how best to dilute and use PlantCatalyst. Dr. Knauf found that PlantCatalyst® plays a role in enhancing germination, increasing growth, and maximizing yield.

University of Wisconsin Department of Soil Science, Madison, WI


Dr. Keith Kelling conducted field trials over several years during the mid-1990’s involving a number of crops including corn, potatoes and others. Dr. Kelling’s research is the earliest known exploration of the PlantCatalyst’s effect on increasing nutrient absorption and its corresponding impact on increased yield. While later research shows that Dr. Kelling was using too much fertilizer and undiluted PlantCatalyst, he was still able to demonstrate the efficacy of the PlantCatalyst® product and provided a strong foundation for further research and exploration.

Strikland Regis Greenhouse, Apopka, FL

This 1994 research took place in greenhouses and was fully filmed. Throughout the study, the plants treated with PlantCatalyst® showed increases in yield and root growth compared to a control group, even when using just half of the regular fertilizer amount.


Vandusen Botanical Garden, Vancouver, British Columbia

African Daisies were split into two groups, one of which was given 20-20-20 fertilizer, and one given 80% of the same fertilizer with an ounce of PlantCatalyst®. The treated plants had bigger, earlier booms than the control group.

Pacific Northwest Garden Supply, Maple Ridge, British Columbia

This test involved 22 sweet cayenne pepper seedlings that were split between a control group and a group treated with ½ ounce of PlantCatalyst® once a week. At the end of the study, the treated plants produced an average of eight ounces of peppers and were 38 inches tall, while the average untreated plants produced an average of 1.75 ounces of peppers and were 29 inches tall.

The Impact of PlantCatalyst® on Cannabis

64 plants (34 treated with 15 mL of PlantCatalyst® diluted in one liter water, 34 treated with only water) were studied through nine weeks of growth. At the end of the study, the largest plants treated with PlantCatalyst® were one third bigger than the largest control plants.
