• A stochastic model of dispersion of cattle excreta in pasture was reported in the previous paper. However, limited information is available on the effects of patchily aggregated return of cattle excreta in pasture on herbage yield. Two problems related to these effects are considered in this paper: (1) How do patchily aggregated excreta depress herbage yield in comparison with evenly scattered excreta? (2) How does the number of patches or lumps of excreta per unit area affect herbage yield? The data obtained may afford useful information for the planning of large scale experiments to evaluate the effect of cattle excreta on pasture fertility.
