Strongly Acid Soil Must Be Limed For Corn, Harold Miller
Strongly Acid Soil Must Be Limed For Corn, Harold Miller
Agronomy Notes
The necessity of liming strongly acid soils that will be planted in corn is well illustrated in a demonstration conducted by Harold Vaught, Area Extension Agent in Adair County.
A field that was well fertilized with nitrogen, phosphorus, and potassium produced low corn yields in 1966. Analysis of a soil sample from the field showed that it was strongly acid soil. (Similar conditions have been reported by many farmers throughout the state in recent years.) Since this field was to be planted in corn again in 1967, a liming demonstration was planned .
Investigation Of Nitrogen Fixation By Three Species Of Lichen, Dortha Maloy Robinson
Investigation Of Nitrogen Fixation By Three Species Of Lichen, Dortha Maloy Robinson
Theses and Dissertations
One species of lichen from each of three different families (Collema wyomingensis , Caloplaca elegans (Link)T. Fries, and Parmelia molliuscula Ach.) was studied to determine whether or not these lichens can fix atmospheric nitrogen. Samples of these three lichens were collected in the early spring of 1967. Samples of each species were placed in 20-ml glass tubes which contained 5 ml of glass wool saturated with 0.5 M nitrogen-free Hoaglands nutrient solution. These tubes were sealed by heat onto a gas manifold system and evacuated. An N15- enriched atmosphere (22 atoms % N15) was introduced into the tubes from the …
Forage Yield And Chemical Composition Of An Orchardgrass-Bromegrass Pasture Mixture As Influenced By Clipping Frequency, Nitrogen Fertilization And Irrigation Regime, Vinayak G. Gawai
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The influence of agronomic practices on forage production and chemical composition of an orchardgrass-bromegrass pasture mixture was studied at the Greenville Farm, Logan, Utah, during 1960-1964. The soil is a well drained Millville Silt loam that has about a one percent slope and occurs on an alluvial fan. It is high in potash, phosphorus and calcium and is alkaline having a pH of 7.9 to 8.2.
Analysis of the clipping frequency showed that the yield of forage from four harvests was greater than from five harvests. This difference was greater on plots receiving high rates of nitrogen fertilization, and frequent …
