There are a number of factors to consider if anhydrous ammonia is applied in the fall. Some of these factors include soil texture, soil temperature, and soil moisture. Other factors are discussed in this article from Extension Agronomy.
Fall fertilizer applications hold some appeal to producers in Kansas. When applying anhydrous ammonia in the fall, there are a few factors to consider. These factors include soil temperature, texture, and moisture.
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.

For fall applications of anhydrous ammonia, there are a number of factors that must be considered, including soil texture, temperature, and soil moisture. Consider the following guidelines discussed in this article before taking to the field.
For fall applications of anhydrous ammonia there are a number of factors to consider including soil temperature, soil texture, and soil moisture. This time of year, it is important to not apply anhydrous while soil temperatures are above a certain threshold. Learn more in this article.

Fall is a good time to plan on fertilizing cool-season perennial grasses such as smooth brome. Brome requires annual fertilization for optimum production. Fertilizer should be applied by broadcasting in the fall or before spring growth begins. This article covers fertilizer application timing and rates for optimum brome production.

Soils across Kansas are still running above 50°F at the 4-inch depth. It is best to delay anhydrous ammonia applications until soil temperatures drop below this threshold. By delaying application until cold weather, over-winter losses of the applied nitrogen can be minimized. Fall applications should be avoided on sandy soils prone to leaching.

Cool-season forages require annual fertilization for optimum production. Fall is a good time to plan on fertilizing cool-season improved pasture perennial grasses such as smooth brome and tall fescue. Fertilizer should be applied by broadcasting in the fall or before spring growth begins.
