Machinery for soil drainage: Comparative analyses made of production volumes of various earthmoving machinery used for preparing land for drainage
by P. Boving
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Production rates—affecting hourly costs—of earthmoving equipment vary with a given piece of work and the type of machine used.

Zinc deficiency in the avocado: Application of zinc chelates to soils may solve the zinc problem in trees on land too steep for spray rig operation
by E. F. Wallihan, T. W. Embleton, Wilma Printy
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Zinc deficiency of avocado trees—a problem common in California orchards—has retarding effects on tree growth, fruit production and in some varieties causes the fruit to be more round than is characteristic for the variety, which reduces the market value.

Fertilizers for timber trees: Exploratory greenhouse investigations show varying responses of timber trees to soils and to applications of fertilizers
by Edward C. Stone
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Preliminary studies on the efficacy of fertilizer applications to forest soils indicate that redwood, Douglas fir, and ponderosa pine respond differently to the fertility level of the soil—as judged by response of agricultural crops—and to the application of fertilizers.

Maleic hydrazide tested on ivy: Growth inhibitor applied by foliar sprays maintained ground and fence covers of ivy for an entire summer without pruning
by C. P. North, G. F. Ryan, A. Wallace

Summary Not Available – First paragraph follows: Cover plants, such as ivies, honeysuckle, and Star Jasmine, may be controlled readily by maleic hydrazide—MH—applied as a spray to new growth.

Potato fertilization and internal black spot in Santa Maria Valley: Fertilization studies show potash deficiency to be closely linked with the incidence of internal disorder of potatoes
by John W. Oswald, O. A. Lorenz, T. Bowman, Marvin Snyder, Harwood Hall
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: The potato defect—internal black spot—involving the variety Netted Gem in the Santa Maria Valley is of considerable economic importance.

Potato fertilization and internal black spot in Santa Maria Valley: Deficiency of important nutrient found to exist in soils of many potato fields during survey and fertilizer experiments
by O. A. Lorenz, F. H. Takatori, Marvin Snyder, Harwood Hall, Herman Timm
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Fertilizer experiments in six potato fields and a nutrient survey of some 25 additional potato fields in the Santa Maria Valley showed that over half the fields were receiving insufficient quantities of potash fertilizers.

Meat in retail grocery stores: Availability of fresh meats, frozen meats, and cold cuts in stores surveyed influenced by store size, ownership, location
by Jessie V. Coles, Marilyn Dunsing
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: The following article is the last of a series of reports of a survey of characteristics of and services offered by retail grocery stores in five counties in California made cooperatively by the Department of Home Economics, University of California, and the United States Department of Agriculture under the authority of the Research and Marketing Act as part of Western Regional Research Project WM-26.

Vinegar fly control treatments: Effectiveness of insecticide formulations and of inert dust diluents assayed in laboratory studies using fruit crop pest
by Walter Ebeling
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Thirty-six insecticides, used both as emulsifiable concentrates and wettable powders—when both were available—and 19 types of inert dust diluents were included in laboratory studies on their immediate and residual effectiveness in the control of vinegar flies—Drosophila melanogaster Meigen.
