- •
We present a suite of methods for quantifying biochar alkalinity in four categories.
- •
Total biochar alkalinity and distribution of alkalis varied widely among biochars.
- •
Base cation concentration was a good predictor of total biochar alkalinity.
- •
Inorganic alkalis comprised >55% of lignocellulosic biochar alkalinity.
