Lincoln's Water Supply Problem
The Conservation Of Nebraska's Water Resources, G. E. Condra
The Conservation Of Nebraska's Water Resources, G. E. Condra
George E. Condra Publications
Oxygen is the first immediate necessity of life and water is second. Both directly and indirectly and more than soil, water is our most basic resource. It is the universal solvent and without it there would be no life, and, of course, no agriculture and industry.

The Effect Of Soil Moisture On The Establishment Of Spruce Reproduction In British Columbia, Percy Munson Barr
The Effect Of Soil Moisture On The Establishment Of Spruce Reproduction In British Columbia, Percy Munson Barr
Yale School of the Environment Bulletin Series
Most of the field work has been conducted at the Aleza Lake Forest Experiment Station, in the valley of the Upper Fraser River, near the city of Prince George [British Columbia].
I. A series of twelve permanent plots (numbers 1 to 12) was established for the purpose of studying the occurrence of natural reproduction on various types of seed bed, under different densities of overwood and on northern and southern aspects. 2. A second series of four plots (numbers 17 to 20) was laid out in logged-off land for the purpose of studying the survival and growth of advance reproduction …

Colloidal Content And Related Soil Factors As Indicators Of Site Quality, Irvine T. Haig
Colloidal Content And Related Soil Factors As Indicators Of Site Quality, Irvine T. Haig
Yale School of the Environment Bulletin Series
This paper presents a study of the correlation between soil colloidal content and soil productiveness and hence a measure of the value of colloidal content in determining site quality. The character of this investigation also permitted incidental observation and comment on the relative value of organic matter, soil acidity, and soil type and class as similar measures. The findings are directly applicable to the forest soils of southern Connecticut and, more particularly, to such of these soils as occur commonly in the vicinity of New Haven. Since these soils are typical of the brown, weakly podsolized forest soils of southern …
Some Aspects Of Soil Moisture In The Forest, Ian J. Craib
Some Aspects Of Soil Moisture In The Forest, Ian J. Craib
Yale School of the Environment Bulletin Series
By determining the moisture content of carefully selected soil samples taken at various depths down to three feet, the moisture content of soils in the forest and in the open have been compared. The soils investigated were similar in their mechanical properties. Part I is an investigation of the effect of forest cover on the amount of water in the soil over the growing season and its availability. Part II is an investigation of the effect of root competition on the available water supply of forest soils.
Tree Planting In Nebraska
Conservation and Survey Division
Introduction. This bulletin is planned to further the planting of trees and ornamental shrubbery in Nebraska. It is the result of cooperation between State, Federal, and University departments, and many State organizations.
The tree-planting campaign of this year (1928) is to begin early in the season and culminate in the American Forest Week (last week in April). It is a State and National movement, a welfare project worthy of the support of every citizen. The cooperation of all Nebraskans is invited.
