Topdressing wheat with nitrogen

The current status of the Kansas wheat crop is very variable. Regardless of the crop condition, now is a good time to start planning for topdress nitrogen applications. Several key elements need to be considered. Learn about those factors in this article.

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.

Nutrient availability in poultry manure

Poultry litter can provide a significant and important supply of nutrients for crop production in areas of Kansas where a supply of litter is available. Poultry litter can serve as an excellent complement to commercial nitrogen (N) fertilizers.

Calculating the value of poultry litter and proper storage considerations

The use of poultry litter can contribute to reducing the cost of fertilizer inputs for many operations, depending on the price and transportation cost of the litter. Poultry litter may represent significant savings particularly in times of high fertilizer prices.

Topdressing canola: How to maximize the benefits

To maximize the yield potential of winter canola, producers should topdress with nitrogen, sulfur, and possibly boron in the winter. Producers should make topdress applications with consideration for the environmental conditions, the nutrients needed, and the application method.

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.

Planning your wheat fertility program: Start now by soil testing

Wheat planting will be here before too long in Kansas. Now is the time to get soil sampling done to have good information to base your fertilizer inputs on. This is particularly important after drought and lower-than-expected yields for previous crops. Due to variable conditions and yield levels across the state, fertilizer needs may require adjustments based on soil tests

Soil fertility and wheat production: Profile nitrate levels and wheat yield

This article addresses the correlation between the amount of nitrate in the soil profile and wheat yield. Failure to account for the N present in the soil wastes a valuable resource. Soil sampling in the fall for nitrate can have a significant impact on N recommendations for winter wheat in Kansas soils.

K-State 2023 Fertilizer Research Report is now available online

The Kansas Agricultural Experiment Station fertilizer reports include preliminary results of research conducted on fertilizer use and management practices for crops in Kansas. This latest report includes topics of using nitrogen, phosphorus, nitrification inhibitors, and chloride application practices in alfalfa, corn, soybean, wheat, and sorghum. The report includes nutrient management methods, tillage, and cover crop best practices.

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.

Updated soil test interpretations and fertilizer recommendations for Kansas

The Agronomy Soil Fertility Working Group at K-State, led by soil fertility specialist Dorivar Ruiz Diaz, has released an updated version of the popular publication "Soil Test Interpretations and Fertilizer Recommendations in Kansas". This publication contains the most recent soil test interpretations for the major crops for the most commonly deficient plant nutrients in Kansas.
