Good afternoon John. My records indicate that I sent you heavy metal and fecal coliform data on March 10,
2017. I have included recent fecal coliform results with this email as I have them in hand. I should have the
heavy metal results well before September 10 and will send them once they arrive. Included with this email is
my annual report, fecal coliform, inert material and my temperature log for the year.

On July 31, 2017, I conducted the Man Made Inert Analysis on screened compost from Windrow # 24. I collected 6 samples from random
locations within the screened compost pile. The dried samples were mix and weighted. The sample was then passed through a one-quarter
inch screen. The material remaining on the screen was inspected and any man made material was collected and weighted. The weight of the
foreign material was divided by the weight of the total compost sample and multiplied by 100:

Dry Compost weight; 17.6 pounds
Foreign Matter weight: .0287 pounds
.0287 divided by 17.6 = .0017 pounds
.0017 times 100 = .17

Subject:Guilford College Compost # 41-25; inert man made
On March 17, 2017, I conducted the Man Made Inert Analysis on screened compost from Windrow # 22. I collected 6 samples from various
locations within the screened compost pile. The dried samples were mix and weighted. The sample was then passed through a one-quarter
inch screen. The material remaining on the screen was inspected and any man made material was collected and weighted. The weight of the
foreign material was divided by the weight of the total compost sample and multiplied by 100.

Dry Compost weight; 9.8 pounds
Foreign Matter weight: .003 pounds
.003 divided by 9.8 = .0003 pounds
.0003 times 100 = .03

Insufficient information is available regarding the first year availability of nutrients in this material. The nutrient availability reported here is therefore the TOTAL nutrients in the material.
Samples submitted prior to 2016 reported an estimated value rather than total nutrient levels. Please contact me if you have any questions.

Reprogramming of the laboratory-information-management system that makes this report possible is being funded
through a grant from the North Carolina Tobacco Trust Fund Commission.
Thank you for using agronomic services to manage nutrients and safeguard environmental quality.

* The electrical conductivity is high in this sample. If using this material in a container substrate mix, take this property into consideration. High EC can indicate good fertilizer value. High
EC can also lead to root damage especially when the media is allowed to dry out. *
