There are a few simple guidelines that we would recommend that you follow to determine if the fields should be retested following flooding. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/636/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=636 Thu, 18 Sep 2008 17:34:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=636 The high price of nitrogen fertilizer has increased interest in planting a legume crop after wheat or canning crop harvest as a green manure to provide some nitrogen credits for next year’s crop. This practice can provide some nitrogen and organic matter as well as increase ground cover to reduce erosion from fields. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/612/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=612 Wed, 06 Aug 2008 16:55:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=612 How much nitrogen (N) loss should I expect from denitrification or leaching and what should I do about it? This article will discuss how to evaluate the potential for N loss and corrective measures that may be taken. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/565/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=565 Thu, 12 Jun 2008 18:33:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=565 Where corn planting has been delayed due to wet soils or where replanting is necessary due to poor stand establishment, use of starter fertilizer is important to increase yields and profits with these plantings. The increased probability of economic response to starter applies even on soils with excessively high P and K soil test levels. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/512/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=512 Thu, 08 May 2008 16:40:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=512 An article by Carrie Laboski, Dept. of Soil Science, UW-Madison http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/471/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=471 Tue, 25 Mar 2008 16:35:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=471 Soil samplers are needed throughout Wisconsin this spring to help answer these questions. They are requested to take part in a project to measure the extent of nutrient stratification in common agricultural soils under different tillage systems. The primary objective of the study is to assess cropland P stratification by soil group and by tillage system for the Wisconsin P Index, but information on potassium stratification will also be collected. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/466/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=466 Thu, 13 Mar 2008 20:47:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=466 The issue of reducing greenhouse gas emissions to address global warming is offering an opportunity to Wisconsin farmers. Farmers can now be paid a soil carbon offset (credit) by enrolling acres in a program that pays them to sequester carbon in crop residues by practicing no-tillage or strip-tillage. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/460/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=460 Thu, 13 Mar 2008 18:05:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=460 After consulting with WDATCP’s pesticide regulatory section, the simple answer is: no.

The Corn/Soy Expo presentation covered a number of issues and suggested several practices that are not part of Wisconsin’s nitrogen management recommendations. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/433/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=433 Wed, 13 Feb 2008 21:55:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=433 In fall 2005 UWEX began using the Maximum Return to N (MRTN) approach to make N rate suggestions for corn. Since that time, both corn and N prices have fluctuated. Currently N prices are high and may continue to move upward as we approach spring. Several of our clientele have asked for an expanded N:corn price ratio chart to reflect current and potential prices. Well, we listened and here it is. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/424/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=424 Thu, 13 Dec 2007 19:25:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=424 Soils are at or near their field capacity water content, which is the point were maximum compaction is possible. The easy, armchair quarterback advice is to stay off these wet soils, but in reality that may not happen. So how much compaction really may occur when heavy equipment is driven on wet soils? http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/393/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=393 Wed, 14 Nov 2007 21:03:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=393 The popular publication Soil Testing Basics has recently been revised by the Nutrient and Pest Management (NPM) Program. Soil Testing Basics is a useful one-page reference resource for individuals involved in nutrient management planning. This publication includes information on why, when, and how to collect soil samples, as well as information on how to complete the soil information sheet that should accompany any samples sent to a lab. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/390/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=390 Mon, 29 Oct 2007 12:13:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=390 Portions of southwestern and southern Wisconsin received in excess of twelve inches of rain in early August of 2007. These storms not only saturated soils in the regions, but in many cases floodwater deposited sediment on crop fields. This event brings into sight a potential for soil compaction from subsequent vehicular traffic used for agricultural operations. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/371/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=371 Thu, 06 Sep 2007 21:17:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=371 Some caution is needed to prevent damage to established alfalfa fields from summer manure applications. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/303/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=303 Wed, 13 Jun 2007 18:31:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=303 The pre-sidedress soil nitrate test (PSNT) is a tool available to Wisconsin corn growers for improving the efficiency of their nitrogen (N) fertilizer applications. Not to be confused with routine soil tests, soil N testing allows N fertilizer recommendations to be adjusted to field-specific conditions that can influence corn N need. http://ipcm.wisc.edu/WCMNews/tabid/53/EntryID/293/Default.aspx cullen@entomology.wisc.edu http://ipcm.wisc.edu/Default.aspx?tabid=53&EntryID=293 Thu, 07 Jun 2007 19:10:00 GMT http://ipcm.wisc.edu/DesktopModules/Blog/Trackback.aspx?id=293
