Bulletin No. 340 - Adult Honey Bee Losses In Utah As Related To Arsenic Poisoning, G. F. Knowlton, A. P. Sturtevant, C. J. Sorenson

UAES Bulletins

During 1947 the 55,000 colonies of honey bees in Utah produced approximately $545,000 worth of marketable honey and beeswax. In addition they pollinated most of the fruit, alfalfa seed, various vegetable and other seed crops. By 1949 the price of honey had declined to where the crop of honey and beeswax was worth $253,000, produced by 49,000 colonies of bees. The value of bees in Utah as pollinating agents to fruit and seed crops greatly exceeds the income received by beekeepers from bee products sold. Because agriculture receives such great benefit from bees, it seems reasonable that farmers who are …

Bulletin No. 338 - Nutrient Deficiencies In Utah Orchards, D. W. Thorne, F. B. Wann

UAES Bulletins

When farm products are sold, some of the essential part of the soil are also marketed. If this process is continued, the soil may be eventually impoverished to the point where it cannot support high crop yields. In addition to direct soil depletion, unbalanced soil management practices may produce soil conditions that prevent or limit the uptake of certain elements by plants even though there may be enough total supply of the elements present to last hundreds or even thousands of years.

Both processes have been going on in many Utah orchards. Sale of fruit has gradually depleted the soil. …

Bulletin No. 345 - Effectiveness Of Gravity Drains And Experimental Pumping For Drainage Delta Area, Utah, O. W. Israelsen, D. F. Peterson Jr., R. C. Reeve

UAES Bulletins

Cooperatie investigations on drainage and reclamation of salted soils in the Delta Area, Utah, were undertaken by the Utah Agricultural Experiment Station, the U. S. Regional Salinity Laboratory, and Millard County Drainage Districts under a memorandum of understanding effective January 1, 1946.

This investigation comprises project 250 of the Utah Agricultural Experiment Station, R. H. Walker, director; and project 50-46-1 of the U. S. Regional Salinity Laboratory, H. E. Hayward, director.

The objectives of the investigations covered by the memorandum of understanding were:

1. To study the effectiveness of present methods of drainage; tile and open drains.

2. To determine …

Bulletin No. 342 - The Nutritive Content Of The Grazing Sheep's Diet On Summer And Winter Ranges Of Utah, C. Wayne Cook, Lorin E. Harris

UAES Bulletins

Approximately two million sheep graze the native ranges of Utah each year. These animals are on the range most of the year and their food supply must come from range plants as they are normally selected. The nutritive value of range forage is often borderline or deficient in essential nutrients, yet, sufficiently adequate to prevent obvious physiological disorders. These mild deficiencies may affect the productive efficiency of the animal even though no symptoms are apparent.
