## Overview

Soil Reef 100% PURE Biochar is a premium, sustainably sourced hardwood biochar with over 82% carbon content, designed to enhance soil nutrient retention and moisture holding capacity. Best used blended with compost and aged for two weeks, it covers up to 24 sq ft per 9 lbs bag and supports healthier plant growth while reducing fertilizer runoff and water use. Perfect for gardeners and commercial applications seeking an eco-friendly soil amendment that acts like a ‘soil reef’ to foster vibrant, living soil ecosystems.

## Description

Soil Reef 100% PURE Biochar is a premium wood-based char product produced via a pyrolysis process technology. APPLICATIONS: For use as a soil amendment, it is best to inoculate or priming it, so that it is adding to the total nutrient quotient of the soil. HOW TO USE: The easiest way to inoculate is to blend Soil Reef's PURE Biochar with a quality compost in a 50/50 ratio, then let it age for at least two weeks under cover. Next, spread 1/2″ – 1″ of this mixture over the soil and till it in 5” deep. For bushes, trees or potting medium for houseplants, use about 10-20% biochar mixture for your total volume. We recommend using 5% by volume of this blended pure biochar. A one cu ft bag covers up to 48 sq ft of garden space when tilled into the first 2 inches of soil. Alternatively, use the Soil Reef's Gardeners Blend which is pre-inoculated and ready-to-use out of the bag. ENVIRONMENTAL BENEFITS: Biochar promotes absorption of fertilizer, heavy metals and other toxins to prevent soil degradation and in turn minimizes pollution to waterways and airways. IN AGRICULTURAL USE: Biochar provides a healthy living soil environment, promoting more vibrant plant growth. It holds moisture, retains nutrients and fertilizer items longer, and holds onto other items required to enhance plant growth. As a result, less watering and less fertilizer is needed in the soil. COMMERCIAL APPLICATIONS: PURE biochar is beneficial for use as an ingredient in many environmental, commercial and industrial applications. THE “SOIL REEF” CONNECTION: Biochar behaves just like a coral reef in the ocean is the basis for so much marine life and vibrance in the ocean. In a soil application, once blended, the many pores in biochar act as a healthy living soil environment. This living soil environment is the essential key to a healthier soil. We caution against the use of chemical fertilizers, which can interfere with this living soil environment.

Review: Soil Reef Biochar Soil Amendment - We are using Soil Reef Biochar to make our own custom blend compost. We mix it half and half with cow compost. Our garden is in an area that used to be a parking lot. It is full of rocks and gravel and the soil is depleted of nutrients. We believe that the biochar mixed with compost will help restore healthy microbial life to our soil. I like the fact that we can mix it with the products that we choose.
Review: whats up with the quantity - everything from 4 lbs to 30 lbs listed in the questions as what you receive. No mention of wet or dry. Product listing is 1 cubic foot, but reviews state 5 gallon buckets which is 2/3 cubic foot. Can we get a straight answer of what we're buying?

## Features

- BIOCHAR: Soil Reef PURE organic biochar is a premium quality 100% biochar sourced from feedstock that is sustainably produced from Pennsylvania forest residual Hard Wood. Soil Reef biochar is a premium biochar, with a Carbon Ratio of 82%+ and can be used in in a range of environmental, commercial, and agricultural applications
- SOIL USE: Like our Soil Reef Gardener's Blend Biochar, pure biochar holds onto nutrients in the soil. However, Soil Reef 100% PURE Biochar typically needs to be inoculated or blended before use as a soil conditioner
- HOW TO BLEND: Before use, mix Soil Reef 100% PURE Biochar with quality compost in a 50/50 ratio and let it age for at least two weeks under cover. The blend is important to provide a healthy living soil environment. This doubles the amended biochar to be applied
- HOW TO APPLY (AFTER BLENDING): Once the pure biochar has been mixed with compost and rested for at least 2 weeks, spread 1/2″ – 1″ of this mixture over your soil and till it in 5” deep. For more application detail, see product description
- TECHNICAL NOTE: Soil Reef PURE Biochar improves the soil’s ability to hold positively charged nutrients (cations) such as potassium and calcium. This process retains many plant nutrients on the soil surface, thereby preventing them from being washed away after heavy rainfall events - reducing leaching of fertilizers, agrochemicals, and nutrients
- COMMERCIAL TYPE USES: Our PURE biochar can be applied in environmental remediation, offsets, building material, “engineered” composites and filtration to name a few. These applications can get complex and may require a biochar with certain carbon properties.

## Questions & Answers

**Q: How much is in a bag**
A: 17 lbs per bag, about the equivalent of a 4-5 gallon bucket. I plan to spread this about 1/2" thick x 12" wide on my garden rows and till it in. I haven't done that part yet, but I'm expecting to get about 100 ' of row "covered". It helps to soak the biochar in compost or comfrey tea for a couple of days to inoculate it with beneficial bacteria before putting it in your soil.

**Q: Is this product good for Organic gardens ?**
A: IT IS PERFECT FOR ORGANIC GARDENS.  In fact, it is beyond what most organic gardeners do.  My soil and plant health have improved since I added this to my soil.  Not only that, but the increase in symbiotic fungi and bacteria avaliable to connect with my plants has greatly reduced their water stress so that I do not have to water as often.

**Q: I have all ready planted my garden.  Can I just put it directly around my plants?  If so, how much do you recommend to put.**
A: I would recomend you use Soil Reef Gardners Blend for this, and yes, you would work it into the root zone around your plants, careful not to damage their roots.

**Q: Do you ship to Canada?**
A: We do not ship to Canada under this offer.  We can ship truck load quantities to Canada, as its cost effective to do so.

### ⭐ whats up with the quantity
*by A***S on May 19, 2023*

everything from 4 lbs to 30 lbs listed in the questions as what you receive. No mention of wet or dry. Product listing is 1 cubic foot, but reviews state 5 gallon buckets which is 2/3 cubic foot. Can we get a straight answer of what we're buying?

### ⭐⭐ Severley underfilled- You are not getting what you pay for
*by D***A on July 25, 2021*

The quality of this biochar product is fine, so I am giving a couple of stars for that. The problem is that, while it is clearly advertised that you will get 1 Cubic Foot of the product, their bags are severely under-filled. I performed a careful measurement and it came in at less than 75% of a cubic foot. The owner of the company does respond to emails, but provides less than satisfactory responses. I was satisfied with quality of this biochar and would have been perfectly happy if he either provided me my missing 1/4 cubic foot or a 25% refund. However his response was "I recommend you buy your biochar where you get the “proper” amount." By this I guess he means from someone who is honest and who will provide full value to their customers. Bio-reef certainly does not. Fortunately there are other producers out their who are honest and provide truthful quantities of a quality product. Update written 3/1/2024. I was just researching suppliers of Biochar to see what the present options are. I found something interesting on Soilreef's website. They are pretty blatantly advertising how under-filled their shipments are. They tell you that to make a 5% biorchar/soil mix you should use one of their "1 Cubic Foot" bags in a 48 square foot area dug in 2 inches. Do the math. If you had a true cubic foot of biochar, you could make a 5% mix in 2 inches of 120 square feet! Obviously they know that if you tried doing that with one their bags, you'd barley have any biochar in your soil, let alone 5%.
