in comparison with Mg concentration at 3 WAT may be attributed to the antagonistic effect of K from the fertilizer source, reduced residual effect of the dolomitic limestone used to adjust substrate pH, or a dilution effect of dry mass and a

susceptibility to a pathogen may suppress diseases by four possible mechanisms ( Wolfe, 1985 ). First, a dilution effect occurs by increasing the distance between susceptible plants, thus slowing the rate of plant-to-plant spread by pathogens. Additionally, a

treatments ( Table 2 ), as reported by Elmer and Pignatello (2011) ; this may be due to the dilution effect of N in faster growing plant tissue, and not to differences in uptake of N among treatments ( Jarrell and Beverly, 1981 ). Foliar contents of Mg and

plant at the lower fertilizer rate could result in a nutrient concentrations being equal due to a dilution effect even though more N, for example, was absorbed at the higher fertilizer rates. This hypothesis could not be tested because tissue levels were
