Using a penetrometer to predict the effects of soil compaction on the growth and yield of wheat on uniform, sandy soils
Australian Journal of Agricultural Research
40(3) 497 - 508
AbstractThe relationships between soil penetration resistance and the growth and yield of wheat were examined for a range of tillage and compaction experiments conducted on earthy sands near Geraldton, W.A. Overall, a single index of penetration resistance explained around 50% of the growth and yield variation, across sites and seasons. Equations using this index showed good potential for predicting the impact of various tillage and traffic practices on wheat yield.
