Our products are phosphorous free, and always have been.


What is it?

SuperRootsTurf is a liquid combination of predictable release macro/micro nutrients, fulvic acid-carbon amendment with plant sourced microbes* (our SoilSeeds product) and endo-mycorrhizae* for on-the-seed application at seeding or at aeration and over-seeding of greens, tees and ornamental grasses.

The benefits…

SuperRootsTurf is specially designed for grasses at seeding. Years of scientific research by the mycorrhizae manufacturer and Plant Essentials’ field experience have shown SuperRootsTurf will hasten the early establishment of grasses with 4 species of endo-mycorrhizae at the manufacturers' recommended rate of 90,000 propagules per acre, along with the other ingredients will jump-start germination and support healthy growth through the early grow-in period. The fulvic acid component will increase the availability of nutrients to the new seedlings and the live microbes will break down those nutrients and existing soil organic matter for rapid root uptake. As a side benefit, the microbes will aid in the reduction of thatch on established turf.

No-clog application…

This clean liquid suspension allows for trouble-free application with hand gun or spray boom methods without nozzle clogging. Maximum benefit will be achieved when applied at 8 oz. 1000 sq. ft., applying more gives no additional benefit.

Right on the seed…

Since mycorrhizal spores are immobile, application to the soil before seeding or directly after seeding is essential for colonization and hyphal growth (threadlike filaments of beneficial fungal mycelia) to occur.

Hydroseeding applications…

Hydroseed germination and establishment results would be greatly enhanced with SuperRootsTurf blended right in the mix with no concerns about damaging the seed.

*The fulvic acid and endo-mycorrhizal components are either USDA organic compliant or OMRI listed, SuperRootsTurf itself is not.

Benefits of endo-mycorrhizae at seeding 

Our own SuperRootsTurf Grow-in Trial 2014

The purpose: 

To compare the seed germination, root development and top growth between SuperRootsTurf (with endo-mycorrhizae) and 16-16-16, the industry standard at seeding. To mimic field conditions, all the test pots were stressed by extended over-watering and drought. Test results from Mycorrhizal Applications Forest Grove, ORE.


The Trial Details

The trial began on 2-7-14 and ended on 4-11-14, the day these samples were harvested.



Soil - GCSA sand from T.E. Walrath. 

Perennial Ryegrass seed from County Green Turf Farm - sown at 10# 1000 / ft2 February 7, 2014.

16-16-16 and SuperRootsTurf, applied at seeding 2/7/14.

Grow lights on during normal daylight hours, off at night.

Temperature at a constant 62 degrees. 

Harvested 4/11/14

Watered by hand as needed

Watered by hand as needed


First visible blades 2/11, 3 days - 8 hours after seeding, on both SuperRootsTurf pots.

16-16-16 pots on 2/11, no visible blades.


16-16-16 on 2-11



2/20 seed germination comparisons






First mowing

1st mowing 2/28 - Note deeper color, seedling density, and a 2/3 reduction in clipping yield for the SuperRootsTurf pots.


Second mowing

                                                                                                                                                                                                                                        2nd cutting 3-10  The reduced clipping yield from the SuperRootsTurf pots was due to the lower nitrogen analysis of 5% and the reallocation of nutrients to root production, not top growth.  SuperRootsTurf sod shows the increased seed germination and extensive root growth that held the exact shape as it was pulled where the 16-16-16 pulled apart easily.


Samples harvested 4/11/14 

16-16-16 @ 5# 1000 ft2


The low density and shorter roots was the result of the increased nutrients stimulating excessive top growth, not root expansion. This sample separated easily when pulled.

16-16-16 & SRT@8oz 1000 ft2 combination


Even though the density of the root system planted with both products was greatly improved, it did not compare to the results of SuperRootsTurf alone.

SRT 16oz-1000 ft2 (double the recommended, label rate)


SRT 8oz- 1000 ft2 (recommended rate)



The increased density and length of the root system of this SuperRootsTurf, label rate sample was the result of the complex nutrient load and the symbiotic relationship between the roots and the endo-mycorrhizae in SuperRootsTurf.


Note the lack of roots in the sand, they were "glued" together by the mycorrhizae and stayed intact when vigorously shaken.

The results speak for themselves:

  •  25% faster germination (3+ days for SuperRootsTurf, 4+ days for 16-16-16) with a significant increase in the number of germinated seeds.
  •  25% quicker blade emergence.
  •  More than 50% increase in visible root mass.
  •  Increased chlorophyll production evidenced by deeper green blade color.
  •  66% less clipping yield due to the reallocation of plant resources to root development, not top  growth which would result in reduced initial mowing and damage would lead to reduced water requirement when field planted.

SuperRootsTurf contains no phosphorus however it "mined" the nutrient from the planting media (sand, in this case) due to the fulvic acids in the product breaking down the molecular size of the nutrient, hastening the uptake by the roots (osmosis). The test showed the addition of 16-16-16 reduced the root mass significantly and hindered the movement of micro-nutrients to the blade viewed by the diminished color in the pots with 16-16-16.  

Plant Essentials is more than pleased with the results of these tests, and is confident SuperRootsTurf will perform equally as well in the field when applied at seeding as directed on the label. Applying more than the label rate (8 oz. 1000/ft2) will not increase performance.
