Topdressing wheat with nitrogen: Timing, application methods, sources, and rates
Now is good time for wheat producers to start planning for topdress nitrogen applications, especially for wheat fields that emerged last fall. Learn about the key elements that need to be considered when deciding on the exact fertilizer program.
Placement and rate considerations for nitrogen application with starter fertilizer
What types of considerations concerning placement and rates of starter fertilizer should producers keep in mind this spring? Read more from Dr. Ruiz Diaz, K-State's Soil Fertility Extension Specialist.
Nitrogen loss potential during the winter and early spring
When field conditions allow, fall application of nitrogen (N) is a common practice for Kansas producers. What factors determine the nitrogen loss potential over the winter and early spring months?

Several factors affect successful soybean inoculation and nodulation
If soybean plants appear nitrogen deficient despite being inoculated, this probably indicates that the inoculant failed. Learn how to assess nodulation of soybean roots in the field and what factors can cause poor nodulation.
In-furrow fertilizers for wheat
Wheat is considered a highly responsive crop to band-applied fertilizers, particularly phosphorus. Wheat plants typically show a significant increase in fall tillers and better root development with the use of starter fertilizer.

Side-dress nitrogen applications for corn: Agronomic considerations and a new crop insurance endorsement
A common concern with side-dress nitrogen applications occurs when producers are unable to apply nitrogen due to wet or poor soil conditions. To help mitigate this risk, the Risk Management Agency (RMA) announced a new crop insurance option (“endorsement”) for northeast Kansas corn farmers who split-apply nitrogen.
Topdressing wheat with nitrogen
Regardless of the crop conditions, wheat producers should start planning for any topdress nitrogen applications. However, differing yield potentials across regions should be taken into consideration when managing the nitrogen fertilizer rate. This article will discuss some of the issues to consider when making topdressing decisions.
Understanding the chemical reactions of urea in the soil
Some common nitrogen containing fertilizers used in Kansas are composed of urea. Questions are often raised about its potential for loss. Chemical reactions of urea in soil and other management factors that affect the performance of urea need to be understood for proper use.
Starter fertilizer and nitrogen placement and rate considerations for Corn
Starter fertilizer is typically considered as the placement of a small rate of fertilizer, usually nitrogen (N) and phosphorus (P), near the seed at planting time. This fertilizer is intended to "jump start" growth in the spring, and it is not unusual for a producer to see an early-season growth response to starter fertilizer application. But some producers might also consider using this opportunity to apply higher rates of fertilizer that can supply most of the N and P needs for the corn crop.
Topdressing wheat with nitrogen fertilizer
Now is a good time to start planning for topdressing nitrogen on wheat, especially with the crop's early green-up this season. Some key elements that must be considered when deciding on the program you plan to use include timing, N source, application method, and N rate.
