Dairy grazing : growth of pasture plants
"This publication replaces Chapter 3, Growth of Forage Plants, in MU Extension publication M168, Dairy Grazing Manual. Original author: Greg J. Bishop-Hurley, University of Missouri."--Page 4."Understanding how plants function (physiology) and their form and structure (morphology) is important when managing grazing animals because both physiological and morphological changes affect plant survival and the quantity and quality of forage. An awareness of how plants respond physiologically and morphologically to their environment provides the basis for understanding how plants react to external factors such as high and low temperatures, drought, light and grazing. This publication presents an overview of basic plant physiology and morphology, and discusses the impact of form and function of plants on grazing management. For more information on the topics discussed in this publication, see the sources listed under Additional reading."--First page.Revised by Robert L.

Agroforestry and grass buffer effects on water quality on grazed pasture watersheds
Paper presented at the 11th North American Agroforesty Conference, which was held May 31-June 3, 2009 in Columbia, Missouri.In Gold, M.A. and M.M. Hall, eds. Agroforestry Comes of Age: Putting Science into Practice. Proceedings, 11th North American Agroforestry Conference, Columbia, Mo., May 31-June 3, 2009.Conservation practices including agroforestry and grass buffers are believed to reduce non point source pollution (NPSP) from grazed pasture watersheds. Agroforestry, a land management practice that intersperses agricultural crops with trees, recently received increased attention in the temperate zone due to its environmental and economic benefits. However, studies are limited that examined buffer effects on water quality on grazed pasture watersheds. Six small watersheds, two with agroforestry buffers, two with grass buffers, and two control watershdeds were used to test the hypothesis that agroforestry and grass buffers reduce NPSP from grazed pasture watersheds. Vegetation in grass buffer and pasture areas include red clover (Trifolium pretense L.) and lespedeza (Kummerowia stipulacea Maxim.) planted into fescue (Festuca arundinacea Schreb.). Eastern cottonwood trees (Populus deltoids Bortr. ex Marsh.) were planted into fescue in agroforestry buffers. Soils at the site are mostly Menfro silt loam (fine-silty, mixed, superactive, mesic Typic Hapludalfs). Watersheds were instrumented with two-foot H flumes, water samplers, and flow measuring devices in 2001. Composite water samples were analyzed for sediment, and total nitrogen after each runoff event to compare treatment differences. Watersheds with agroforerstry and grass buffers had significantly lower runoff volumes as compared to the control watersheds. The loss of sediment, and total nitrogen were smaller for the buffer watersheds. The results of the study suggest that establishment of groforestry and grass buffers help reduce NPSP pollution from grazed pasture watersheds. It is anticipated as trees grow and roots occupy more soil volume, the reduction in N in runoff should increase on the agroforestry watershed.Ranjith P. Udawatta (1, 2), Harold E.

Forage crop irrigation systems and economics (2013)
"Agriculture."Irrigation presents an opportunity for Missouri forage producers to mitigate production risk from drought. This guide explores three areas to consider before choosing a forage irrigation system: expected forage response, equipment options and the economics of irrigating forage.New 11/13/Web
Agroforestry and grass buffer influences on water infiltration for a grazed pasture system
Paper presented at the 11th North American Agroforesty Conference, which was held May 31-June 3, 2009 in Columbia, Missouri.In Gold, M.A. and M.M. Hall, eds. Agroforestry Comes of Age: Putting Science into Practice. Proceedings, 11th North American Agroforestry Conference, Columbia, Mo., May 31-June 3, 2009.Agroforestry and grass buffers are often adopted as an alternative resource management system in agriculture for environmental and economic benefits. The objective of the study was to compare agroforestry (AgB) and grass buffer (GB) systems under rotationally grazed (RG) and continuously grazed (CG) pasture systems on water infiltration measured using ponded infiltration and tension infiltration methods. Buffer areas were fenced which prevented cattle grazing in buffer areas. Soils at the site are Menfro silt loam (fine-silty, mixed, superactive, mesic Typic Hapludalfs). Infiltration rates were measured using ponded ring infiltration units in 2007 and 2008 for the four treatments with six replicates. Infiltration rate as a function of tension (at 50-, 100-, and 150-mm) was also measured using a tension infiltrometer in 2007. Water infiltration parameters were estimated using Green-Ampt and Parlange infiltration equations. Quasi-steady state infiltration rates (qs) and field-saturated hydraulic conductivity (Kfs) for the buffers were about 30 and 40 times higher compared to pasture treatments, respectively. Green-Ampt and Parlange models appeared to fit measured data with r2 values ranging between 0.91 to 0.98. The infiltration rate in 2007 for the GB treatment was the highest (221.4 mm h-1) and for the CG treatment was the lowest (3.73 mm h-1). Estimated sorptivity (S) and saturated hydraulic conductivity (Ks) parameters were higher for buffers compared to the pasture treatments. Grazing reduced infiltration rates for the pasture (CG and RG) treatments. Results show that the buffer areas have higher infiltration rates which imply lower runoff compared to pasture areas.Sandeep Kumar (1), Stephen H. Anderson (1), Ranjith P.

Missouri's ultimate feed alternative : ammoniated tall fescue (2009)
"Reviewed February 2009."To stretch short feed supplies, livestock producers could ammoniate low-quality tall fescue hay. Ammoniated hay is hay placed under a tarp and treated with a maximum of 60 pounds of anhydrous ammonia per ton of hay. After three weeks, the ammonia treatment is complete, and the hay is fairly good quality. It is also affordable in drought years, when hay and feed are limited. Tall fescue hay should cost about 12 per bale
