Considerations for Use of Enhanced Efficiency Nitrogen Fertilizers

Many formulations of urea fertilizers or chemicals to treat urea are on the market today. Only a few are effective at protecting the fertilizer from quickly losing N.

Pinto Bean Response to Phosphorus Starter Fertilizer in East-central North Dakota

This is a production reference to highlight pinto bean fertilizer research.

Pinto bean response to starter and foliar fertilizer

A study to examine the performance of pinto bean with selected treatments of phosphorus (P), zinc (Zn), and sulfur (S) starter and post-applied fertilizer.

Site-specific Farming: Active Optical Sensor Algorithms for Corn Yield Prediction and a Corn Side-dress Nitrogen Rate Aid

Research from 2011 to 2013 has resulted in a data base that supports the use of active-optical sensors to direct side-dress N rate in corn. Previously, rates were determined using a grower's best guess.

Site-specific Farming: Active-Optical Ground-Based Sensor Algorithms as Tools for Determining Need in Spring Wheat

Up until now, there has been no scientific method to determine whether or not a late-season N application would be helpful to increase protein or not. The information in this publication will help growers/crop consultants make this…

Site-specific Farming: Active-Optical Ground-Based Sensor Algorithms as Tools for Determining Top-Dress N rate

Although some states have algorithms for directing top-dress wheat N rates, until now North Dakota did not have any. These algorithms will assist growers in determining whether or not in-season N rates are necessary and help them determine…

Site-specific Farming: Developing Zone Soil Sampling Maps

This circular, although originally published in 2008 is still relevant and useful as is. Although almost half of the ND farmers utilize some site-specific technology, the other half would also benefit from its use.

Site-specific Farming: What is Site-specific Farming?

This circular, although originally published in 2008 is still relevant and useful as its. Although almost half of ND farmers utilize some site-specific technology, the other half would also benefit from its use.

Soil Fertility Considerations for Buckwheat in North Dakota

Buckwheat is grown every year in North Dakota and is an important specialty crop grown for grain in conventional and organic farming systems. It's ability to cycle phosphorus from slowly available to more available forms is referred to in…
