Influence of soil type on reforestation in Humboldt County
by D. W. Cooper
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Forestry is the major source of income for Humboldt County, with more than 90% of its land area in wildlands. Approximately three quarters of the wildlands are in conifer forests and one quarter in rangelands.

Summary Not Available – First paragraph follows: An economic study of young-growth timber taxation—using Mendocino County as a case area—provides factual information and analysis for the work of the Joint Timber Taxation Study Committee.

Evaluation of materials for livestock shades applicable to other open-type structures
by T. E. Bond, C. F. Kelly, W. N. Garrett, LeRoy Hahn

Summary Not Available – First paragraph follows: In animal environment investigations in the Imperial Valley the most economical means of reducing the heat stress of farm livestock during the summer months was provided by shades.

Studies on beef cattle grazing irrigated forage as part of sound pasture management
by J. L. Hull, J. H. Meyer, G. P. Lofgreen
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Sound pasture management must consider the requirements of both plants and animals and their interrelationships. One of the most important factors that can be controlled in a system of grazing management is the length of the regrowth interval of the forage between grazings. Tests recently conducted at Davis, during two pasture seasons, studied the effect of forage recovery intervals of 24, 30 and 36 days. The stocking rate was held approximately equal to obtain the same degree of grazing intensity.

Experiments show protein supplements to be of dubious value with alfalfa
by Robert D. Appleman, Donald G. Addis, S. E. Bishop
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Dairy cows fed a concentrate mixture containing 50% expeller-processed copra meal produced 0.12 pound per cow more butterfat daily than cows fed an equal amount of a high energy concentrate, lower in fat and in protein content.

Field tests for effective control of flies in farm and ranch buildings
by I. Barry Tarshis, Morton Smith
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Dibrom—in sprays or in sugar baits—gave successful fly control at a stock farm in Whittier, a cattle ranch in La Puenta, a dairy in Artesia, and a poultry ranch in Moorpark.

Field tests for control of grape leafhoppers resistant to insecticides
by F. L. Jensen, E. M. Stafford, H. Kido, C. D. Lynn
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: The grape leafhopper in San Joaquin Valley vineyards has developed resistance to DDT, to malathion, and to Sevin. Resistance problems are most severe in the Orange Cove area, and extend beyond Orosi and Dinuba in Tulare County and beyond Reedley in Fresno County.

Potential crop damage by the morning-glory leaf miner to sweet potatoes in California
by H. H. Shorey, L. D. Anderson
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Sweet potatoes typically have fewer insect pest problems than do most other vegetable crops. However, a potentially serious pest in California which occasionally reaches outbreak proportions on sweet potatoes is the morning-glory leaf miner—Bedellia somnulentella Zeller.
