Potential for Nitrogen Loss from Heavy Rainfalls |
|
|
By WCM Staff on
6/12/2008 12:33 PM
|
|
|
|
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.

Late-Planted and Replanted Corn Likely to Respond to Starter Fertilizer |
|
|
By WCM Staff on
5/8/2008 10:40 AM
|
|
|
|
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.

Project to look at nutrient stratification in Wisconsin’s agricultural soils |
|
|
By WCM Staff on
3/13/2008 2:47 PM
|
|
|
|
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.

Carbon credits available for no-till and strip-till crop production |
|
|

|
|
|
|
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.

Supplemental Nitrogen to Corn Price Ratio Table |
|
|
By WCM Staff on
12/13/2007 1:25 PM
|
|
|
|
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.

Manage traffic on wet soils to limit soil compaction |
|
|
By WCM Staff on

|
|
|
|
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?

Revised Soil Testing Basics Publication Now Available |
|
|
By WCM Staff on
10/29/2007 6:13 AM
|
|
|
|
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.

Managing Soil Compaction Following the Heavy Rains of 2007 |
|
|
By WCM Staff on
9/6/2007 3:17 PM
|
|
|
|
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.

Wisconsin’s Pre-sidedress Soil Nitrate Test |
|
|
By WCM Staff on
6/7/2007 1:10 PM
|
|
|
|
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.

Planting corn immediately after anhydrous ammonia application, am I in for trouble? |
|
|
By WCM Staff on
4/24/2007 10:51 AM
|
|
|
|
The weather conditions this spring have kept corn growers out of the field until this past week. A few growers are concerned about germination and seedling injury because they will be applying preplant anhydrous ammonia (NH3) only a few hours before planting. The questions are: what should they do to prevent or minimize injury; and what should they expect the crop to look like?

Soil Test for Professionally Managed Turf |
|
|
By WCM Staff on
4/4/2007 10:06 AM
|
|
|
|
This past year the University of Wisconsin Soil and Plant Analysis Lab-Madison introduced a new soil test package for golf courses as well as other professionally managed turf. Beginning in April 2007, the UW Soil and Plant Analysis Lab-Madison is now also offering a special nutrient management package for professionally managed turf. Samples submitted using this program are tested for pH, organic matter, Bray P and K only.
