Researchers identify a key molecule in nitrogen-fixing bacteria

Molecular biologists at the University of Massachusetts Amherst who study nitrogen-fixing bacteria in plants have discovered a "double agent" peptide in an alfalfa that may hold promise for improving crop yields without increasing fertilizer use.

The economic return to soil test information

Fall after harvest is an excellent time for soil sampling and testing. This year, with low grain prices, many producers may be looking for places to cut costs. However, cutting back on soil testing could result in lowering profits.

Having accurate soil test information is critical to making the right decisions regarding fertilizer input. Fertilizer cost has remained steady while grain prices have dropped this fall. Therefore, making good use of fertilizer input becomes critical to maximize profits.


Grassley asks for details on justification for costly NH3 rule

Senator Chuck Grassley is sending a letter to Labor Department Secretary Tom Perez about a rule governing anhydrous ammonia retailers. The letter is in response to a revised regulation where the Labor Department and OSHA re-interpreted a statute governing aspects of process safety of facilities after an ammonium nitrate explosion in West, Texas. Previously, the department’s interpretation of the same rule had exempted retail sellers of anhydrous ammonia.


CSNT shows low accuracy for evaluating corn deficiencies

A high percentage of corn fields may receive substantially more N fertilizer than is economically optimum, for which there are no obvious visual signs. Conversely, fields deficient in N have obvious visual cues, such as stunted growth and yellowing leaves. The Corn Stalk Nitrate Test (CSNT) has been used for two decades by farmers and consultants as an end-of-season tool for evaluating field-specific corn N management practices.
