Webtest extracts with those of HWT boron in 100 soil samples in six states of this region. Results showed that the M-3 method extracted similar amounts of boron as the HWT method, but more boron than the M-1 method. Both methods were significantly correlated with HWT B (r = 0.82 and 0.74, respectively) (see Reference 3), so either the M-1 or M-3 http://corn.agronomy.wisc.edu/Management/pdfs/a2522.pdf
