The Conservation Of Nebraska's Water Resources, G. E. Condra Oct 1930

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 Jan 1930

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 …


Nebraska Facts, Walter Kollmorgen Jan 1930

Nebraska Facts, Walter Kollmorgen

Conservation and Survey Division: Faculty and Staff Publications

Nebraska Facts, compiled by Walter Kollmorgen in the 1930s for the Conservation and Survey Division of the University of Nebraska, presents a concise statistical and descriptive overview of the state of Nebraska during the early twentieth century. The publication synthesizes data on Nebraska’s geography, climate, natural resources, agriculture, industry, transportation infrastructure, public health, and education. Emphasis is placed on the state’s agricultural productivity, manufacturing capacity, and favorable economic indicators, reflecting Nebraska’s role as a leading contributor to national food production and livestock markets during this period. The work also highlights public institutions, including the capitol building and the University …

Colloidal Content And Related Soil Factors As Indicators Of Site Quality, Irvine T. Haig Jan 1929

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 Jan 1929

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: Faculty and Staff Publications

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.
