Synopsis Moisture storage was increased 3 out of 6 years under stubble mulching and was not decreased the other 3 years. Grain yields were correlated with moisture available to the crop. Nitrate nitrogen in the soil was less under stubble mulch than under no‐residue but amounts were adequate to produce grain yields as great as possible with existing moisture supply. Fertilization with N increased the nitrate nitrogen content of the soil but had no effect on grain yields.
