Tb28: Weight, Nutrient Element And Productivity Studies Of Seedlings And Saplings Of Eight Tree Species In Natural Ecosystems, Harold E. Young, Paul M. Carpenter Nov 1967

Tb28: Weight, Nutrient Element And Productivity Studies Of Seedlings And Saplings Of Eight Tree Species In Natural Ecosystems, Harold E. Young, Paul M. Carpenter

Technical Bulletins

The objective of this study was to obtain weight and nutrient element information on complete trees ranging from 1 to 35 ft in height above ground for the same eight species (red spruce, balsam fir, white pine, hemlock, northern white cedar, white birch, red maple and aspen) as a downward extension in size classes.


B655: Maine Egg Marketing: A Structural Study, Chung-Jeh Yeh Nov 1967

B655: Maine Egg Marketing: A Structural Study, Chung-Jeh Yeh

Bulletins

This study, from 1967, was designed to provide basic information concerning the movement of table eggs through the major marketing firms located in Maine. The primary purpose of the report was to aid in better understanding the structure of the present egg marketing systems in Maine in order that: (1) efficient alternatives to the present egg marketing systems could be developed, and (2) Maine's competitive position in out-of-state markets could be improved.


Tb27: Fresh And Dry Weight, Nutrient Elements And Pulping Characteristics Of Northern White Cedar, Thuja Occidentalis, Richard F. Dyer Aug 1967

Tb27: Fresh And Dry Weight, Nutrient Elements And Pulping Characteristics Of Northern White Cedar, Thuja Occidentalis, Richard F. Dyer

Technical Bulletins

Northern white cedar was selected as an eighth species for complete tree investigation of weight, nutrient elements and pulping characteristics because it comprises approximately 13% of the total softwood growing stock in Maine, but only amounts to about 2% of the total softwood timber cut for all purposes. It is hoped that the information in this bulletin will provide basic information permitting northern white cedar to become a more meaningful segment of the Maine forest economy.


B646: Aerial Photographic Methods Of Potato Disease Detection, F. E. Manzer, George R. Cooper Mar 1967

B646: Aerial Photographic Methods Of Potato Disease Detection, F. E. Manzer, George R. Cooper

Bulletins

Aerial photography was shown to be a valuable tool for the detection of late blight and other diseases and disorders of potato. Aero infrared and Ektachrome Aero Infrared films were used to demonstrate that potato foliage, normally highly reflective to near-infrared radiation, loses this property when in an unhealthy condition. The 10 in reflectivity seems to vary in proportion to the magnitude of the vine damage. Vine damage resulting from infection by the late blight fungus can be detected on either of the infrared film before visual plant symptoms develop.


Tb26: Native Bees Associated With The Low-Bush Blueberry In Maine And Eastern Canada, L. W. Boulanger, G. W. Wood, E. A. Osgood, C. O. Dirks Feb 1967

Tb26: Native Bees Associated With The Low-Bush Blueberry In Maine And Eastern Canada, L. W. Boulanger, G. W. Wood, E. A. Osgood, C. O. Dirks

Technical Bulletins

Native bees are particularly important pollinators of lowbush blueberry. Changes in certain cultural practices since the 1930s, however, have caused substantial reductions in the native bee populations. Recent observations, however, have shown that adjustments in these practices can have a beneficial effect on native bees with accompanying increases in their numbers. Collections of native Apoidea were made in various areas of Maine and eastern Canada from 1961 through 1965 to determine the species present and their relative abundance in blueberry fields. Of the 89 species collected, 59 were taken on lowbush blueberry blossoms, and 10 in close association with lowbush …


Tb25: The Effect Of Stand Factors On The Productivity Of Wheeled Skidders In Eastern Maine, Ernest B. Harvey Iii, Thomas J. Corcoran Jan 1967

Tb25: The Effect Of Stand Factors On The Productivity Of Wheeled Skidders In Eastern Maine, Ernest B. Harvey Iii, Thomas J. Corcoran

Technical Bulletins

The objective of this study was to determine what forest stand factors, as they constitute a set of operating conditions, affect skidder and skidder crew productivity and the degree of their effect.


Account Book, Cecil Pierce, 1967-1991, Cecil Pierce Jan 1967

Account Book, Cecil Pierce, 1967-1991, Cecil Pierce

History of Maine Fisheries

Account book of Cecil Pierce, a lobster fisherman out of Southport (Me.). Records sales of lobsters and shrimp caught, including dollar amount received but not weight or quantities, and expenses paid for bait, license fees, supplies, utilities, boat maintenance and other items. Last page of book records expenses for “new house,” dated late 1970s. Pierce was credited for inventing one of the first plastic vents on lobster traps that enables smaller lobsters (“snappers” or “shorts”) to escape the traps unharmed, thus encouraging conservation of the species.
