Factors Affecting Irrigation Water Use In Southwest Missouri And Soil Microbial Response To Irrigation And Crop Residue, Shirley M. Dobbs
Factors Affecting Irrigation Water Use In Southwest Missouri And Soil Microbial Response To Irrigation And Crop Residue, Shirley M. Dobbs
MSU Graduate Theses
Sustainable use of water resources in Southwest Missouri requires a better understanding of factors that influence groundwater use by crop producers. The objective of this study was to assess the influence of weather patterns and edaphic factors on water used for agricultural irrigation. Groundwater withdrawal data from 14 high-use agricultural irrigation wells were monitored between 2009 and 2016 as part of the Southwest Missouri Irrigation Project. Stepwise and linear regression was used to assess the relationship of weather and edaphic factors in response to annual water use from each well. Precipitation volume, number of precipitation events, average maximum and minimum …
Effects Of Irrigation On Forage Growth Rates On Rotational Grazing Dairies, Zachary Davis
Effects Of Irrigation On Forage Growth Rates On Rotational Grazing Dairies, Zachary Davis
MSU Graduate Theses
The amount and timing of rainfall in Missouri can be very irregular. This causes issues for producers of agronomic products in the state who rely on forages for income. The most sensible approach to the problem is the use of irrigation. But there is little useful information to reference when implementing this management decision. By studying three different styles of irrigation (center pivot, spider, and k-line) on 4 species of forages native to Missouri (alfalfa, crabgrass, perennial ryegrass, and tall fescue/clover), this study provides valuable insight as to the cost and benefit of irrigation. The main goal is to produce …
