A lot of anhydrous ammonia is going on this spring, and in many fields the hope is to plant as soon as practicable after NH3 application. This brings up the question about potential for NH3 damage to seeds and seedlings.
Genetic modification of maize over the last century has led to desirable shoot characteristics and increased yield - and that likely contributed to the evolution of root systems that are more efficient in acquiring nutrients, such as nitrogen, from the soil, according to a new study.
An international team of researchers, including three from the U.S. Department of Energy’s Brookhaven National Laboratory, has tracked nitrogen as soil bacteria pull it from the air and release it as plant-friendly ammonium.
Terra Nitrogen Company, L.P. announced the completion of the planned turnaround of an ammonia and UAN plant representing approximately one-half of the production capacity at its Verdigris, Okla., nitrogen complex.
On March 6, 2015, revised guidelines for fertilizing corn grown on irrigated sandy soils were released by the University of Minnesota. Minnesota has about 500,000 acres of irrigated sandy soils. Corn is grown on about half of these acres in any one year. With the use of irrigation and fertilizer, sandy soils are very productive.
EuroChem Group AG, Maire Tecnimont and SACE jointly announced the signing of a Memorandum of Understanding in relation to the construction of five ammonia-urea plants to be commissioned in Russia, the United States and Kazakhstan over the next 10 years.
Recently, a group of scientists, industry representatives, farmers and government and non-government organization members met to discuss managing nitrogen on farms with the goal of “Mo Fo Lo Po:” more food, low pollution.

The use of starter fertilizer placement on the seed (known as in-furrow placement) is commonplace in many areas of Minnesota. I commonly receive questions on the value of in-furrow starter fertilizer when corn prices are low. The application of liquid fertilizer with the planter presents additional costs which may or may not be warranted depending on the year and where a field is located within Minnesota.

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.
