Always check which basis a sulphur figure is quoted on. These are typical values, not guaranteed constants. Leonardite is a mined mineral and batch-to-batch variation is significant, so analysis is run per batch, on request. A certificate of analysis for the batch supplied is available on request. WHAT THE RESEARCH ON HUMIC ACID AS A CLASS SHOWS A 2024 meta-analysis (Ma, Cheng & Zhang, Agronomy 14: 2763) of humic acid amendments reported an average +12% crop yield, +27% nitrogen use efficiency and +17% nitrogen uptake. That study tested humic acid products as a class . SoilBoost EA was not among the products tested , and the authors report that effects diminish outside the pH 6 to 8 range. An earlier meta-analysis (Rose et al., 2014) of 81 studies with more than 700 observations found average shoot dry weight increases of about 22% and root dry weight increases of about 21% Sold on Chemiseed Sdn Bhd (https://chemiseed.com/products/soilboost-ea-1kg).
