Summary of pasture biomass estimates on the rotational grazing (CS6) system 1990-2010

Pasture swards are complex systems of growing grasses and forbs, that are grazed during the growing season and occassionally cut for hay. As a result, it is difficult to characterize their productivity and this can be confounded by heifer management. In this report, we summarize the three different approaches used to develop pasture biomass estimates […] More »

Midwest Cropping Systems Effects on Soil Properties and on a Soil Quality Index

ABSTRACT Cropping systems may improve or decrease soil quality depending on the specific crop rotation, nutrient amendments, and tillage practices employed. We conducted this study to determine the effect of six cropping systems in the Wisconsin Integrated Cropping Systems Trial on soil properties after 18 years of continuous treatments. We sampled soils (0-5-cm and 5-20-cm […] More »

Management-Intensive Rotational Grazing of Dairy Heifers on WICST (1999-2000)

Management-intensive rotational grazing (MIRG) is a low input form of dairy herd management that is increasing throughout the United States. In Wisconsin, about 23 percent of dairy farmers used MIRG last year, more than triple that since 1993 (Jackson-Smith and Powell, 1999). Of the three dairy forage systems represented in the Wisconsin Integrated Cropping Systems […] More »

Comparison of WICST Forage Systems: Productivity and Profitability from 2004-2006

The dairy industry is undergoing rapid change within Wisconsin (CIAS 2005; PATS 2005). In addition to the trend of increasing animal concentration and custom feed production, other producers are looking to alternative markets such as grass-fed and organic labels to increase their profitability. Each strategy implies a somewhat different forage production approach. In this study […] More »

Rotational Grazing with Dairy Heifers on WICST: Pasture Productivity, Heifer Weight Gain And Profitability ( 2000-2006)

Profitable livestock production is the objective of all forage systems. Managed grazing continues to be an attractive option for many because of its relatively low capital investment as well as the aesthetically pleasing and appealing lifestyle it offers. Authors: Janet Hedtcke, Josh Posner More »

WICST Forage Systems Comparison: Production, Milk Models and Gross Margins

Forages play a major role in Wisconsin agriculture. Over 3 million acres of Wisconsin cropland are in alfalfa, grass and clover hay and pasture, similar to the acreage in corn production (WI Ag Stats, 2004). They play a major role in dairy and beef rations as well has horse diets, providing 50 to 100% of […] More »

Effects of Agricultural Cropping Systems on Soil Microbial Community Structure

Microorganisms of the Bacteria (no nucleus), Eucaryotes (nucleus), and Archae (an ancient anaerobic group) were sampled using molecular techniques so that unculturable microorganisms could also be assessed. The general structure of the microbial community changed with cropping system (CS3, CS5, CS6) at Arlington in one soil sampling time in 1996. The Eukaryotes dominated in relative […] More »

WICST Intensive Rotational Grazing of Dairy Heifers in 1997 and 1998

Of the three dairy systems represented in the Wisconsin Integrated Cropping Systems Trial (WICST), rotational grazing is the lowest input system. Pastures were established at the Lakeland Agricultural Complex (LAC) and the Arlington Agricultural Research Station (ARS) in 1990. Initially, species included red clover, smooth bromegrass and timothy; later, orchardgrass, perennial ryegrass and reed canarygrass […] More »
