Using Humic Acid in the Compost Pile
by Haydn Gunningham
(Perth - Western Australia)
It appears that the humic acids available in Australia are of poor quality as the process of extraction from Leonardite (ie brown coal) tends to de-nature the biology of the humates. Therefore, instead of using the humic acid as a food source for brewing compost “tea”, it has been suggested that I use it to moisten my compost pile. I am using a 26% liquid concentrate and dilute this concentrate in water by 100:1.
Question 1: Would you please advise if I should (or can) use a stronger mix say, 20:1 and if so would this benefit the compost?
Question 2: Would you pls ask your "Tribe" members if they know of a good quality source of humic acid is available in Australia?
