- Abstract:
- ... One of the goals of the Forest Service, U.S. Department of Agriculture's Forest Inventory and Analysis (FIA) program is large-area mapping. FIA scientists have tried many methods in the past, including geostatistical methods, linear modeling, nonlinear modeling, and simple choropleth and dot maps. Mapping methods that require individual model-based maps to be produced are time and labor intensive. ...

- Abstract:
- ... Forests in the Central Hardwood region are undergoing change in terms of area, volume, species composition, and forest structure. These forests are dominated by deciduous species; are increasing their average stand size, volume, and age; and, are experiencing woody plant species replacement as shade intolerant species are being replaced by more shade tolerant species. As changes progress, concerns ...

- Abstract:
- ... An inquiry into the losses of nitrogen from the urine of farm animals was thought desirable because many farmers practice storing the liquid manure in tanks until convenient to apply it to the land. The question of the efficiency of these tanks in preserving the urine has often arisen. In these investigations a study was made as to nitrogen losses from urine (a) exposed to the open air, (b) in Bun ...

- Abstract:
- ... A review of the available data indicates that, within reasonable limits at least, variations in ear characters are rather neutral in their effect upon the yield of dent corn, except when they are definitely linked with special adaptive growth characteristics of the plant. Thus, slender ears with smooth, shallow kernels tend to be produced on earlier maturing, smaller, and less rank growing plants ...

The data of this investigation of the effects of treatments of acid phosphate and limestone on pasture land were secured by ascertaining the yield and chemical analysis of the total vegetation on small areas (3/4000 acre each) of both treated and untreated parts of the same pasture field. Four fields, each located in a different county, were included in the investigation. Three of the four receive ...

And unless proper cognizance of the biology of the insect is ...

In every case where phosphate fertilizers had been applied the growth had noticeably ...

The normal absorption of soil moisture by wilted seed tubers was impeded. 3. Under drouth condition ...

This paper is a progress report of 3 years work on an experiment designed to determine the adaptability to Wisconsin dairy farms of an intensive system of pasture management involving systematic rotational grazing and annual applications of nitrogen in the form of calcium cyanamid, as well as potash and phosphate fertilizers when needed. The experiment is located on the Hoard's Dairyman Farm where ...

One pound of sodium chlorate in a gallon of water (12%) applied to 100 square feet is usually sufficient, but with unfavorable climatic and soil conditions, especially where sandstone comes close to the surface, the st ...

The acre yields of the F2 generation of 10 double crosses among selfed lines of corn were from 4.0 to 19.9 bushels, or from 5 to 24%, less than those of the F1 generation of the same crosses, with an average decrease of 12.1 (standard error = 1.5) bushels, or 15.2%. The value of such a loss would more than compensate for the cost of F1 seed even at present prices (1933). Variation in the size of t ...

- Abstract:
- ... Solutions of K salts with and without conditioner were added to four soils in sufficient solution to bring the soils approximately to field capacity. The conditioners were HPAN (hydrolized polyacrylonitrile) and IBMA (isobutylene maleic acid). The treated soils were incubated for several days, oven-dried at 68°C., and K fixation against extraction with NH₄OAc was determined. The results indicated ...

- Abstract:
- ... Various procedures were used for extraction of Al from Ohio soils representing a wide range in extractable Al. One normal NH₄OAc at pH 4.8 was selected as an extracting solution because of its superiority over Ba(OAc)₂ and BaCl₂. One normal NH₄OAc plus 0.2 N BaCl₂ was no better than NH₄OAc alone. At this pH it extracts enough Al from most soils for accurate measurement with little possibility of d ...

In the lake plain area of northwestern Ohio they are the dominant soil group. These soils have developed under conditions of poor or very poor drainage.

Tile flow was more closely related to the position of the WT in the profile than to the height of the WT ...

- ... Variation of soil properties within mapping units of Seward, Rimer, Wauseon, Rawson, Haskins, and Mermill soils in northwestern Ohio was statistically summarized. These series have sandy or loamy upper sola that overlie a fine-textured substrata. Ten randomly selected profiles within each of 22 delineations of these soils were characterized by field study. Standard deviation, standard error of the ...

- Abstract:
- ... Soils in the eastern extremity of the Prairie Peninsula have developed during most of their history under forested conditions. Biogenic opal isolated from the 50-20µ fraction of 55 profiles representing different topo- and biosequences in western Ohio indicates that most Mollisols (Brunizems) of this area have similar total opal accumulations and depth-distributions as their Alfisol (Gray-Brown Po ...

- Abstract:
- ... More than a half-million hectares of the moderately well-drained Canfield soil and its toposequence members occur in northeastern Ohio and northwestern Pennsylvania. These fragipan soils derived from low-lime glacial till are intensively used for both agricultural and urban purposes. Because this soil is being used for a long-term study of the disposition of strontium-90 under natural conditions a ...

- Abstract:
- ... Elemental and mineralogical evidence indicate that both loess and outwash deposits on relatively high Illinoian-age terraces are more intensively weathered than comparable units of lower level Wisconsin-age terraces. The Illinoian site, particularly in the outwash paleosol, has lower weight percentages of heavy minerals; lower hornblende contents; lower elemental Fe, K, and Ca contents; and more p ...

- Abstract:
- ... A large computer and multivariate statistics were used to select a minimal number of soil properties with the greatest prediction value for use in soil classification. Key communality cluster analysis and principal axis factor analysis with Varimax rotation were applied to six sets of soil data containing from 21 to 66 profile characteristics. The analyses selected from four to seven factors or di ...

- Abstract:
- ... Metabolic rates in a sewage—treatment lagoon system near Deshler, Ohio, were investigated between March 21 and June 10, 1964. The ponds were well mixed vertically, exhibiting daytime average eddy diffusivities of about 1 cm²/sec. The waters had a high titratable base, ranging from 3 to 10 meq/1 during the period of study. Low oxygen levels were encountered for only a short period in the second sta ...

- Abstract:

Experiments by the Ohio Valley Experiment Station at Point Pleasant, West Virginia were conducted over an eight-year period to test for response to nitrogen and potassium fertilizer by hurley tobacco (Nicotiana tabacum L.). Both yield and quality were affected by the level of fertilizer use, with the effects due to nitrogen more pronounced. Quality as measured by price is maximized with an average ...

Chemical, physical, mineralogical, macro- and micro-morphological data are presented for Bt and C horizons of Nappanee profiles (Aeric Ochraqualfs); three of which were sampled in the lake plain region of Ohio and the fourth on the Defiance Moraine in Michigan. Calcareous till deposits are similar across the study area: lake plain sites average 36% clay vs. 40% for the Michigan site; carbonate equ ...

- Abstract:
- ... Population studies were conducted on the eastern fence lizard in South Carolina, Texas, Ohio, and Colorado. Hatching occurs in early to middle summer and well into the fall in southern populations, but is restricted to late summer and early fall in Colorado and Ohio. The hatchlings in Texas reach a mature size in 3 months and these lizards, as well as those in South Carolina, reproduce before they ...

- Abstract:

Previous studies comparing the accumulated heat unit (AHU) method with the calendar day method for classifying corn (Zea mays L.) hybrids with respect to maturity do not clearly show the superiority of the AHU method over the calendar day method. They appear to have two limitations: (1) the range of climatic conditions under which the studies were conducted was not broad enough to elicit wide vari ...
