Summary Given certain prior information about residues from earlier applications of a quantitative factor Q to crops grown in rotation, this paper shows how relatively simple experiments can be used to provide estimates of the optimum applications of Q to successive crops; the estimates obtained allow for the presence of residues. The prior information in the particular case discussed is that if x units of the factor are applied then the residues one, two, three ...t... seasons later are rx, rpx, rp2x, ...rpt−1x..., where r and p are constants such that 0≤r〈1, 0≤p〈1.
