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. ...

... 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 ...

9. Ear-type selection and yield of dent corn

Subject:
Zea mays; dent corn; crop yield; USDA; Nebraska; Illinois; Kansas; New York; Ohio
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 ...

Abstract:
... 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 ...
