  1. The following soil characteristics were measured at the National Soil Fertility and Vegetable Nutrition Laboratory: texture (sand, clay and silt), pH, organic matter (% Walkley–Black), total nitrogen (%), phosphorus (Olsen ppm), and cation exchange capacity (CEC). We sampled 12 plots in total, sample size N = 3 per treatment combination
