Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Optimizing crop N use efficiency using polymer-coated urea and other N fertilizer sources across landscapes with claypan soils
(University of Missouri--Columbia, 2008)
Development of improved management practices to increase nitrogen use efficiency (NUE) within agricultural fields is needed to improve crop production and reduce nitrogen (N) loss. Field studies planted to maize were conducted in 2005 and 2006...
Winter rations for dairy heifers
(University of Missouri--Columbia, 1917)
The special object of these experiments is to compare the efficiency and economy of rations which are conducive to rapid growth with rations of such character as to admit of but limited growth....
Bed degradation of the lower Missouri River
(2013-06-04)
The phenomenon of bed degradation can be due to a multiplicity of causes, but ultimately reflects a change in either the sediment input or sediment transport capacity of a system. Causes for the accelerated rate of degradation of the lower Missouri...
Field pennycress management in upstate Missouri
(University of Missouri--Columbia, 2017)
increased yield in this one-year experiment. Residue and tillage management will be important in future field pennycress research. This research has identified potential seeding date, pre- and postemergence herbicide safety to field pennycress as well...
Evaluating effects of neonicotinoid seed treatments and agroecosystem land management practices on solitary bees in Midwestern agroecosystems
(University of Missouri--Columbia, 2021)
Bees are declining due to multiple factors including habitat loss and non-target exposure to pesticides resulting from agricultural intensification. Solitary bees are often overlooked as important pollinators, but they are valuable contributors...
Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)
(University of Missouri--Columbia, 2009)
A stem analysis was perform to examines the effects of thinning treatments on Melina (Gmelina arborea) wood quality and tree architecture in the North Coast of Colombia. 27 plots under forest management regimes and age ...
An experimental study of the rest period of plants : the effect of rest period breaking agencies upon hardwood cuttings
(University of Missouri--Columbia, 1916)
several years ago by Dr. W.L. Howard, then, of the Missouri Experiment Station.-- Pages 1-2....
Glyphosate resistance : pollen movement within a common ragweed (Ambrosia artemisiifolia L.) population and herbicide release from common waterhemp (Amaranthus rudis sauer) plants
(University of Missouri--Columbia, 2011)
Common ragweed and Common waterhemp are native, summer annual weeds distributed widely throughout the United States. Both weed species have developed resistance to the broad-spectrum herbicide glyphosate. Research was ...
Herbage accumulation, nutritive value and nitrogen dynamics of a tall fescue forage system with either nitrogen fertilization or intercropped sunn hemp
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Elevated temperatures and declining precipitation during the summer results in tall fescue [Schedonorus arundinaceus (Schreb.) Dumort., nom. Cons] forage systems limiting cattle...
Heterogeneity in body condition, survival, and seasonal origins among lesser snow and Ross's geese
(University of Missouri--Columbia, 2018)
condition among hunter harvested individuals and the general population of midcontinent lesser snow and Ross's geese during the spring Light Goose Conservation Order in 2015 and 2016 across Arkansas, Missouri, Nebraska, and South Dakota. I found a body...
A quarterly econometric model of the United States beef sector
(University of Missouri--Columbia, 1982)
The United States beef sector has been modeled in many studies, perhaps, because beef represents a large proportion of the consumer food dollar and agriculture’s income. The predictive performance of these models has been, however, quite...
Assessing the capacity for collaborative ecosystem stewardship on private forestland in the Missouri Ozarks
(University of Missouri--Columbia, 2007)
Missouri's forestland totals nearly 15 million acres and a vast majority of this area, roughly 82 percent, is controlled by more than 300 thousand nonindustrial private forest (NIPF) owners. Consequently, meaningful long-term stewardship...
Playa wetland plant and soil response to predicted climate and land use change in the southern Great Plains
(University of Missouri--Columbia, 2019)
, and microbial community and structure; (2) compare ecosystem response to changing climatic conditions between Northern (Nebraska) and Southern (Texas) playa soils; and (3) assess effectsof increased agricultural nitrogen inputs on playa plant communities...
A study of the relation of type and conformation to production in dairy cattle
(University of Missouri--Columbia, 1913)
The subject of dairy type and conformation is a question of vital importance to all breeders and students of dairy cattle. It is a well-known fact that from the standpoint of milk production there is no method of ascertaining ...
Methods for high-resolution soil-landscape modeling in midwest upland landscapes
(University of Missouri--Columbia, 2008)
. These methods were tested in the upland landscapes of northern Missouri. Sensors, especially DRS, successfully estimated profile clay and organic carbon. Peak functions were valuable for modeling profile clay content and covariates of clay. Coherent depth...
Factors affecting the growth of dairy animals
(University of Missouri--Columbia, 1916)
Text from introduction: All successful breeders are continually striving to improve the quality of their herds. The value of any dairy herd is determined to a great extent by the way in which the heifers within that herd ...
Developing and evaluating the effectiveness of a place based climate change education toolkit in Missouri
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Climate change is the most serious environmental issue facing humans in modern society. It is more relevant today than ever before since a massive increase in greenhouse gas...
A study of the processes of fat metabolism and methods for the determination of fat
