Natalie van Hoose, Purdue University Ensuring that corn absorbs the right balance of nitrogen, phosphorus and potassium is crucial to increasing global yields, a Purdue and Kansas State University study finds. A review of data from more than 150 studies from the U.S. and other regions showed that high yields were linked to production systems in which corn plants took up key nutrients at specific ratios - nitrogen and phosphorus at a ratio of 5-to-1 and nitrogen and potassium at a ratio...

Halving the amount of nitrogen fertilizer used in certain areas of China would substantially decrease greenhouse gas emissions without affecting crop productivity and the area's natural carbon sink. This is according to a new study, published today, 1 November, in IOP Publishing's Environmental Research Letters, which showed that a 60 per cent reduction in fertilizer use would significantly reduce emissions from areas that are, anyway, "over-fertilized", such as the North China Plain and...

Modern Hybrid Corn Makes Better Use Of Nitrogen

Today's hybrid corn varieties more efficiently use nitrogen to create more grain, according to 72 years of public-sector research data reviewed by Purdue University researchers. Tony Vyn, a professor of agronomy, and doctoral student Ignacio Ciampitti looked at nitrogen use studies for corn from two periods — 1940-1990 and 1991-2011. They wanted to see whether increased yields were due to better nitrogen efficiency or whether new plants were simply given additional nitrogen to...

A new model probes to new depths in search of nitrogen Large amounts of nitrogen are stored in the soils of agricultural areas in Nebraska and Maryland, according to a new study by the U.S. Geological Survey (USGS) and the U.S. Department of Agriculture (USDA). Once in the soil, nitrogen can be converted to nitrate, which can readily move to groundwater. "We expected to find nitrogen stored in organic matter in these soils, but didn't realize how much," said Tom Nolan, USGS hydrologist, who...
