METALS


Biochar Now has commissioned extensive third party test for its biochar. Below is a table of several metals including some that are highly toxic. Due to its cation exchange capacity, the biochar removal results are often exceptional.

Interestingly, once toxic substances are attracted and bonded to the biochar walls, they are considered to be encapsulated and will not leave on their own. Even plant roots will not take up the bound toxins.

NUTRIENTS


Nutrients are an important adsorptive category for biochar. At times, the data is important for nutrient availability (eg for plants) and other times it’s important for nutrient removal (eg field runoffs and waterways). In both cases BN biochar is an excellent performer. As a side note, it is helpful to know that porous bags with nutrient-laden biochar can be recovered and used in gardens and ag fields for improved plant growth.

SOLIDS


When BN biochar is loaded in porous bags and placed in a nutrient polluted lake, pond or river, the natural currents will flow the water through the bag and biochar. The nutrients are attracted by the biochar but solids, such as those listed below, not attracted. However, they will be physically filtered due to the jagged exterior of biochar. (See figure 3).

The physical removal of algae blooms (turbidity) and clay (solids) by biochar is very effective. (See Table 3 below).

WATER SEQUESTRATION


Water holding is a very important property of BN biochar because of drought conditions in California and other states. The biochar holds 5.6 times its weight in water and is always root-available. Evaporation is negligible due to the long, narrow pores with very small openings at the ends as seen in Figure 3 above.

Water holding capacity = 5.6 x the weight of biochar
