Yes! MightyGrow Fertilizer have been reviewed and approved by the Organic Materials and Research Institute (OMRI). Our OMRI certificates are available for download on the product pages.

Thankfully, arsenic is no longer used in commercial poultry farming. Just to be on the safe side, though, we regularly test for heavy metals. Testing is required by OMRI and other organic certifying agencies.

MightyGrow Fertilizer are NOT raw, but have been processed into a safe, stable, environmentally friendly organic fertilizer. In fact, Mighty Grow supplies fertilizer to municipalities for land remediation around creeks and streams. RAW poultry litter can pollute surface and ground water, as evidenced by environmental problems that have occurred in areas of concentrated poultry production.

No. Once Mighty Grow Fertilizer are either mixed with your soil or watered into your lawn, the minimal odor dissipates very quickly, generally overnight.

Many people have experience burning when using RAW poultry manures. MightyGrow fertilizers are made from processed manure. When used as directed, Mighty Grow will not burn your plants or your lawn. Because MightyGrow is 10x more nutrient dense than composted manures, you can use less, rather than more, to achieve great results.

No! We follow the guidelines of the National Organic Program for processing manures. Adequate heat is achieved twice during processing, completely eliminating any pathogenic bacteria.

The nitrogen in poultry litter is normally a combination of fast-release ammonia and slow-release nitrates. Our process converts much of the nitrogen into a slow-release form of nitrogen while the remainder is immediately plant available. MightyGrow Fertilizer is ready to go to work as soon as it hits the ground and will feed your soil for several months.

MightyGrow is superior to other products in several ways:

1. Some poultry litter based fertilizers are made from composted manure, which has a low nutrient analysis.
2. MightyGrow is fortified with bio-available trace minerals.
3. MightyGrow is inoculated with a proprietary blend of soil microbes that create the synergy needed for optimum soil and plant health.

The N-P-K of an organic 4-5-5 performs better than a synthetic 12-15-15! Why? Some of the nutrients in pure poultry litter fertilizer are NOT water-soluble, therefore they stay in the root zone, right where you put them. Contrast this with conventional synthetic fertilizer that can be washed away with one heavy rain. It is for this reason that many gardening experts equate the nutrient value of an organic fertilizer with three times that of synthetics.

Synthetic fertilizer feed the plant directly, often to the detriment of soil health. Further, the higher nitrogen content in synthetic fertilizer starts evaporating when the bag is opened and continues leaching out of the soil as soon as it rains. University studies all agree that synthetic nitrogen can suffer up to a 60% loss due to evaporation or leaching. The lack of any appreciable nitrogen leaching is a primary benefit to using organic fertilizer like MightyGrow Fertilizer.

No! The opposite is actually true. The quantity of MightyGrow Fertilizer needed should actually decrease over time because it builds organic matter and nutrient levels in the soil. When you use synthetic fertilizer, it’s like putting your lawn or garden on IV drugs because synthetics break down and leach nutrients from the soil. This soil sterilization creates an addiction, increasing the demand for more and more fertilizer over time.

No. MightyGrow Fertilizer only have to be applied twice a year. That is a benefit to using a slow release fertilizer.

Yes. MightyGrow Fertilizer is safe and natural, and won’t harm people, plants or pets. It is recommended that you water the lawn after applying MightyGrow Fertilizer to work it into the root zone.

We recommend that MightyGrow fertilizers are used within one year of purchase. Although the microbes in our fertilizer are in a state of suspended animation, conditions where they are stored could cause some deterioration. Store the bags in a cool, dry location out of direct sunlight and your Mighty Grow Fertilizer will be ready for you when you are ready for it.
