Inhoud: The boron sorption isotherm method of soil testing may provide an estimate of the fertilizer required to bring the soil to an optimum boron level. Data from the boron isotherm experiment suggests that at low concentrations a plot of added boron vs equilibrium solution boron will be linear. The boron concentration at which this plot becomes linear will depend on the characteristics of the soil tested. The data, from this and other studies, suggest that 0.5 ppm boron in the equilibrium solution should be the approximate upper limit of boron concentration where this relationship is linear. Since boron added is linear with respect to boron in equilibrium solution, boron fertilizer required to adjust the equilibrium solution concentration can be calculated from the least squares regression equation of these two variables. This fertilizer requirement can only be determined when the optimum level of boron in equilibrium solution is known. Thus, further study is needed to establish this optimum level for all plant species.
