Principles of Tillage to Boost Yields by S P Farm Adviser
Hardy W Campbell of the Southern Pacific urges soil preparation and timely cultivation to raise yields under irrigation and in dry farming. He cites wheat trials, orchard trials, and a 4000 acre California peach yard to argue for even irrigation, fine root beds, and a granular mulch to maintain soil moisture and air. Campbell promotes soil fertility through proper tillage and offers SP Bulletins No 10 and 12 for farmers seeking guidance.
