Formulating N Recommendations for Corn in the Corn Belt Using Recent Data
نویسندگان
چکیده
Introduction Making N rate recommendations for corn has been one of the most economically important goals of publicly funded crop production and soil fertility personnel and programs over the past five decades. Changes in cropping systems, hybrids, tillage, and other management practices, along with opportunities in site-specific inputs and awareness of the need to minimize the amount of N that reaches surface and ground waters have combined to increase the interest to re-examine N rate recommendations, and to formulate new recommendations if current data support such changes.

A Historical Perspective on Nitrogen Fertilizer Rate Recommendations for Corn in Indiana (1953-2011)
For many years, N recommendations in the Midwest were based on achieving a specific corn yield goal (if you want so many bushels per acre, apply so much N). This began to change in 2006 when several universities in the Corn Belt adopted a substantially different N recommendation system. That system was developed from recent N trial results and took into account the relative costs of grain and N...
متن کاملPhosphorus and Potassium Placement Methods for Corn and Soybean: an Iowa Perspective
Increasing fertilizer prices and awareness of potential impacts of excessive or badly applied nutrients on water quality has renewed interest in fertilizer management strategies that reduce nutrient inputs or improve efficacy. Fertilizer recommendations for phosphorus (P) and potassium (K) in Iowa and most states of the Corn Belt are based on soil testing and maintenance of desirable soil-test ...
متن کاملImpacts of recent climate change on Wisconsin corn and soybean yield trends
The US Corn Belt supports agroecosystems that flourish in a temperate climate regime that could see significant changes in the next few decades. Because Wisconsin is situated on the northern, cooler fringes of this region, it may be the beneficiary of a warmer climate that could help support higher corn and soybean yields. Here we show that trends in precipitation and temperature during the gro...
متن کاملRecent land use change in the Western Corn Belt threatens grasslands and wetlands.
In the US Corn Belt, a recent doubling in commodity prices has created incentives for landowners to convert grassland to corn and soybean cropping. Here, we use land cover data from the National Agricultural Statistics Service Cropland Data Layer to assess grassland conversion from 2006 to 2011 in the Western Corn Belt (WCB): five states including North Dakota, South Dakota, Nebraska, Minnesota...
متن کاملRegional Approach to Making Nitrogen Fertilizer Rate Decisions for Corn
Nitrogen fertilizer is one of the largest input costs for growing corn. Across the Corn Belt, N is typically the most yield-limiting nutrient. Facing record high N fertilizer prices and potential supply problems, producers are concerned about N fertilization rates. Soil fertility researchers and extension specialists from seven states across the Corn Belt (see list in acknowledgements section) ...
