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.

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?

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.

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.

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

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.

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.

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.
