Summary of the 8th and 9th seasons of WICST including on-farm and on-station satellite trials. This issue includes several reports on soil biodiversity.

The Dynamics of Root Growth under Different Management Systems

The research quantified the dynamics of root development for corn. The line intersect technique was utilized in order to estimate the root length and the health status of roots at different nodes. Intact rooting systems were sampled from plants at different dates. However, simple measurements with this technique do not yield an overall [...] More »

Krusenbaum Farm Project Update

This case study documents the start-up of a successful alternative dairy farm in Wisconsin. Initially the vision was to establish a 97-hectare biodynamic farm with dairy and cash cropping. Low milk prices throughout most of 1991 and the heavy workload associated with conventional dairying forced the farm family to look for alternative strategies. [...] More »

Chemlite: Corn Response to Commercial Fertilizer in Cropping System Three at Lakeland, 1997

During the first several growing seasons of the WICST project, corn yield in Cropping System Three was less than expected. Satellite studies were initiated in 1994 at both locations to determine if supplemental nutrients, applied as starter, side dress N or a combination could increase yield. Results through 1996 are reported in the [...] More »

Weed Seed Bank Changes on WICST: 1990 to 1998

Crop management systems influence various aspects of the soil, not the least of which are weeds. The rotation, tillage system, intensity of herbicide use, and integration (or lack there of) of herbicides with other control practices will certainly affect the weed seed bank. While this principle is well recognized, seed bank data to [...] More »

WICST Educational Outreach at Arlington 1997 and 1998

There was a continuation of activities that had been started in previous years. These included tours for 4th grade elementary students, and an UW Soil Science class, and the Prairies Jubilee and DeForest Middle School Science Field Days. In the winter, a presentation on WICST was made to farm students enrolled in the [...] More »

WICST Educational Outreach at Lakeland 1997 and 1998

If everyone who reads this outreach report would ask themselves, “What can I do to support the sustainable future of our food production system?” and then use the following questions as a guide, we all can make a difference in the future. When you need to make a decision that could make a difference [...] More »

WICST Communications Activities 1997 – 1998

This has been a year of reaping what was sowed in previous years. Despite much reduced hours devoted to communications, we seem to have hit our stride in many ways. The WICST newsletters were unusually well received, and our mailing list grew substantially from individuals asking to get on it. A number [...] More »

Krusenbaum Dairy Herd Health and Production Report, 1997 and 1998

This report summarizes major production and health results of the Krusenbaum dairy herd for calendar years 1997 and 1998. The report is based upon Dairy Herd Improvement (DHI) records from AgSource and upon field investigation reports from the UW School of Veterinary Medicine Author: Ken Nordlund, DMV More »

The Effects of Crop Rotations on the Nitrogen Availability to a Subsequent Corn Crop

The primary goals of any cropping system are to optimize plant-available nitrogen (N), maintain profitability by reducing input costs, and conserve a precious resource base by minimizing pollution from nitrate-nitrogen (NO3-N). Nitrogen is an essential plant macronutrient and the major growth-limiting factor in most US agricultural soils. In the United States, NO3-N is [...] More »

1992-1998 Economic Analysis of the Wisconsin Integrated Cropping Systems Trial

The 1998 economic analysis for the Wisconsin Cropping Systems Trials marks a new approach to evaluating the systems. In the past, the economic analysis has been compiled by different economists and agronomists that evaluated the data a year at a time. This year’s evaluation uses a more consistent process over 1992-1998 for Cropping [...] More »
