Five American farmers and their fertilizer retail partners have been named as 4R Grower Advocates for 2015 by the Fertilizer Institute (TFI). The winners represent growers and retailers across the nation who are dedicated to the 4Rs of nutrient stewardship - using the right nutrient source at the right rate, the right time and in the right place.
In April 2014, Emerson Nafziger, University of Illinos, wrote on the topic on N fertilizer on soybeans, reporting that research at the University of Illinois has rarely shown a benefit in yield to applying N fertilizer during the middle part of the season. But it seems that some people, perhaps reacting to testimonials of high yields after using N fertilizer in the high-yield conditions of 2014 remain convinced that adding N fertilizer “makes high yields higher.”
Talking Stick Resort was again the site for the 24th Annual Fluid Forum held from February 15 to 17 in Scottsdale, Ariz., as researchers and ag people from the United States and overseas gathered for two days of sharing the latest in field research to improve crop yields.
Sales in Brazil of fertilizers and pesticides for next year's soy crop have stopped after the main lender for the farm sector, state-run Banco do Brasil, froze disbursement of subsidized loans, farm and industry groups said on Wednesday.
Water-borne algal blooms from farm fertilizer runoff can destroy aquatic life and clog rivers and lakes, but scientists report that they are working on a way to clean up these environmental scourges and turn them into useful products. The algae could serve as a feedstock for biofuels, and the feedstock leftovers could be recycled back into farm soil nutrients.

Early spring is the time wheat growers implement nitrogen (N) fertilization strategies. This means estimating the amount of N needed and estimating how much of the N might be lost due to excessive rainfall and saturated soils.
Starter fertilizer can be used to complement pre-plant fertilization of crops to increase yield and economic returns to production. However, its use will not be beneficial in all production conditions.
Over the last several decades there have been substantial yield improvements in soybean. Because of new varieties and new agronomic practices, the yield potential in soybean is higher now than ever before. But a lack of updated information on the nutritional needs of soybean crops may be limiting the crop's potential.
