Analytical and empirical relationships are established among parameters of spatial interactions among plants (Mead's coefficient of inter-plant interaction (competition), Smith's empirical law of soil heterogeneity, intra-plot correlations, and spatial autocorrelation).The significance of spatial inter-plant interactions on the statistical efficiency of field design, sample sizes, and field estimates is discussed. Besides providing insight into the complexities of inter-plant interactions, the exposition also provides procedures for removing the bias generated by these interactions, and algorithms for obtaining spatial parameters from ANOVA results.
