The Economics of Soil Testing

cullen@entomology.wisc.edu — Mon, 26 Oct 2009 20:09:51 GMT

Soil testing is the only tool we have to evaluate pH, phosphorus (P), and potassium (K) status of the soil. Knowing this information allows growers to make economically optimum applications of lime and phosphorus and potash fertilizer. In these times of economic uncertainty, managing input costs is an important component of farm sustainability.

Nutrient Management and the NRCS Conservation Stewardship Program

cullen@entomology.wisc.edu — Thu, 24 Sep 2009 20:56:04 GMT

Through this volunteer program, farmers must agree to maintain existing conservation practices and to do more conservation practices during the five years of the contract. Certain improvements to nutrient management practices related to nitrogen and phosphorus applications are valued under this system.

PSNT – does it mean anything this year?

cullen@entomology.wisc.edu — Thu, 18 Jun 2009 16:16:44 GMT

Over the past week I’ve received a few inquiries regarding the validity of the pre-sidedress nitrate test (PSNT) for corn this year considering the cool weather this spring. This is a very valid question for many in Wisconsin. To answer it, we’ll look at research results and weather summaries.

Wisconsin’s Pre-sidedress Soil Nitrate Test

cullen@entomology.wisc.edu — Thu, 11 Jun 2009 16:18:19 GMT

The large amount of rain some portions of the state have received in the spring of 2009 may have some corn growers wondering about the nitrogen (N) status of their fields. Is the N from earlier fertilizer applications still there? Are the manure-N or legume-N credits really available to this year’s corn crop?

Compaction on Crop Land

cullen@entomology.wisc.edu — Thu, 16 Apr 2009 17:48:01 GMT

Producers are concerned that compaction from heavy equipment will negatively affect soil quality factors such as bulk density, porosity, aggregation, and drainage; causing yield reduction that may persist for several years.

Consider Spring Tillage Options

cullen@entomology.wisc.edu — Thu, 02 Apr 2009 19:55:18 GMT

Many growers are now faced with the decision of tillage or no-tillage; or if tillage will be done how much will be needed. This decision is likely very specific to a particular farming operation and factors such as whether manure has or will be applied, crop rotation, soil type, and if the planter can function in high residue will need to be considered.

Frost seeding red clover into winter wheat publication

cullen@entomology.wisc.edu — Thu, 12 Feb 2009 21:01:04 GMT

The publication’s objective is to help farmers evaluate the economic potential of using red clover as a green manure cover crop, providing biologically fixed nitrogen to the following year’s corn crop. This is in addition to the soil quality, soil conservation and weed suppression benefits likely to accrue. Direct link to file >> Frost Seeding Red Clover file

What happens when a soil is completely flooded for periods of a week or more? There are a few simple guidelines that we would recommend that you follow to determine if the fields should be retested following flooding. More...

Late Summer Planting Legumes to Produce Nitrogen Credits for Next Year

cullen@entomology.wisc.edu — Wed, 06 Aug 2008 16:55:00 GMT

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. More...
