Soil and Manure Testing

Get ready for spring manure application
By Natalie Rector
What can you do to improve manure management on your farm? It all depends on where you are currently at and how far you want to go. Read entire article from Michigan Farmer.

Test manure for nutrient content
By Natalie Rector
Fall signals a busy time to empty manure pits and clean out livestock pens. Knowing the soil test values, manure nutrient content and rate per acre of manure is important information for producers. Read entire article from Michigan Farmer.

PSNT saves money, aids environment
By Natalie Rector
People ask me how I became involved in studying manure. It all began with pre-sidedress nitrate soil testing. After the 1988 drought, farmers began asking Extension agents if the nitrogen that is applied to corn wasn’t used to the poor yields, would it be available for the ‘89 group?

Manure Testing Laboratories
Manure is an asset, not a liability. It is a source of plant nutrients, increases the soil’s water holding capacity, and improves soil tilth. Developing a plan to properly manage the time, form and placement of manure ensures. Read entire article

How to take a PSNT soil test
The Pre-Sidedress Nitrate Soil Test (PSNT) is most widely used in field corn production, but is adaptable for use in other field crops and vegetables. Read entire article

Soil Sampling for Variable Rate Fertilizer and Lime Applications
Variable rate fertilizer application has become a major component of the fertilizer industry. The technology for its development has progressed in tandem with Differential Global Positioning Systems (DGPS), the two combining to provide for accurate "on-the-go" variation in fertilizer application.

Understanding Soil Phosphorus - University of Wisconsin
This 32-page, color publication summarizes the issues associated with phosphorus and its potential for impact on the environment.

Capture Land-Applied Manure in the Root Zone
Management practices that capture land-applied manure in the root zone will increase nutrient availability, improve soil quality, and prevent manure nutrient and contaminant losses in runoff. Read entire article

Recycling Nutrients for Crops
Manure is good stuff! Manure contains nitrogen (N), phosphorus (P), potassium (K), sulfur (S), and micronutrients. Manure applications over time improve soil quality (e.g., nutrient supplying capacity and soil tilth). Taking credit for manure nutrients may reduce your fertilizer bill. Read entire article

Stop Fertilizing, But Let the Cows Graze!
Farmers who find excessive levels of nitrates in groundwater can keep on grazing their cattle without fear of further contamination from the nitrogen in cattle waste as long as they reduce or eliminate nitrogen fertilizer application for at least a few years. Read entire article
