Improved sugar beet harvester: Gives high quality performance but more development required
by John B. Powers
Not available – first paragraph follows: A sugar beet harvester developed at Davis and tested in dry, peat-loam soil at Clarksburg, October 16, 1947, gave 93.7% root recovery and only 6.8% dirt pickup.

Effect of molybdenum: On livestock in permanent pastures
by H. S. Cameron , H. Goss
Not available – first paragraph follows: The development of permanent pasture in certain areas of the state has been accompanied by a somewhat obscure disease affecting the young stock grazing on pastures, “up to the hocks in feed, but starving to death.” Based on investigational work in England on a comparable condition there is a probability that the element molybdenum may be an important factor in causing the disease.

Sheep production: Program recommended
by R. F. Miller

Since sheep fit well into grain farming rotation to restore soil fertility, they can be used profitably on the worn out grain land which has been over-farmed in California.

by Coit A. Suneson , John W. Oswald
