1980-2014: U.S. Corn Production More than Doubles; While Fertilizer Use Remains Almost Level
The Fertilizer Institute (TFI) announced today that between 1980 and 2014, U.S. farmers more than doubled corn production using just under six percent more fertilizer nutrients than were used in 1980. The announcement is based on fertilizer application rate data released today by the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS). Specifically, ...

Fertilizer placement affects nutrient leaching patterns
Controlled-release fertilizers (CRFs) are a widely used method of delivering nutrients to nursery container crops. The fertilizers contain encapsulated solid mineral nutrients that dissolve slowly in water, and are then released into substrates over an extended period of time. Although the use of CRFs is an accepted practice, growers and researchers are always looking for ways to decrease ...

Nitrogen mysteries in urban grasslands
Areas of turf-forming species created and maintained by humans for aesthetic and recreational (not grazing) purposes, i.e. “urban grasslands” are an extremely common, but poorly studied ecosystem type. There are over 150,000 km2of urban grasslands in the U.S. and many receive high rates of fertilizer, creating concerns about nutrient runoff to streams, lakes, and estuaries and emissions of ...

Iron deficiency in soil threatens soybean production
An expansion of soybean production into areas where soybean has seldom, if ever, been grown can be problematic for some farmers. Soils having high pH values and large amounts of calcium and/or magnesium carbonate are notoriously iron deficient. Iron deficient soils in the North Central United States are estimated to reduce soy bean production by 12.5 million bushels every year. John Wiersma, a ...

Urgent Action Needed to Address Africa’s Soil Health Issues, Say Experts
One of the best prospects for feeding Africa’s rapidly growing population is to increase the sustainable use of fertilizers, a high-level panel of experts is expected to say today at an international meeting of the World Food Prize. Despite 10-year-old commitments to expand the use of fertilizer in African agriculture, the continent still averages around one-tenth of fertilizer use per ...

Many Countries Reaching Diminishing Returns in Fertilizer Use
By Lester R. Brown When German chemist Justus von Liebig demonstrated in 1847 that the major nutrients that plants removed from the soil could be applied in mineral form, he set the stage for the development of the fertilizer industry and a huge jump in world food production a century later. Growth in food production during the nineteenth century came primarily from expanding cultivated area. It ...

The Inaugural High-Level Plant Nutrition Forum Calls for a New Agenda for Plant Nutrition
As the world rushes towards a population of 10 billion people by 2050 while simultaneously facing the perils of climate change, global agricultural systems must evolve to ensure our sustainable future. On November 18th and 19th, the International Fertilizer Association (IFA) convened leading experts from diverse sectors including the research and farming community, international organizations ...
