Seedlings on old citrus soils: Effect of water, acid, alkali, and alcohol leaching of old citrus soils on growth of citrus seedlings
by James P. Martin
| Full text HTML  | PDF  
Not available – first paragraph follows: Orange, lemon, and grapefruit trees in most southern California citrus-producing areas do not grow so well when planted in soil previously cropped to citrus as when planted in a soil for the first time.

Spot-wise seeding for redwood: Artificial reforestation by seeding or planting necessary on cutover land devoid of seed trees
by Emanuel Fritz
| Full text HTML  | PDF  
Not available – first paragraph follows: Cutover redwood timber lands—those without seed trees—can not be expected to reforest naturally and need help from artificial reforestation.

Phosphate test for grain land: Bingham soil phosphate test enables accurate prediction of yield response of cereals to phosphorus fertilization
by W. E. Martin, J. R. Buchanan
| Full text HTML  | PDF  
Not available – first paragraph follows: Grain fertilizer tests with uniform fertilizers were applied in over 200 separate field tests in 40 counties during the past three seasons—covering most grain-growing areas of the state and representing a wide range of soil series.

Eradication of pocket gophers: Comparative field tests demonstrate best poisons, baits, and dosages for practical gopher control
by Milton A. Miller
| Full text HTML  | PDF  
Not available – first paragraph follows: The most effective and economical method for eradicating pocket gophers-responsible for a major share of the multimillion dollar damage inflicted annually on California agriculture by field rodents—is by poisoning.
