Using different bacteria but the same overall setup, the researchers later turned nitrogen gas into ammonia for fertilizer, which could offer a more sustainable approach to the energy - guzzling method used for fertilizer production today.

Food production is rising sharply, requiring more carbon - based fuels and nitrogen - based fertilizers, both of which exacerbate global warming, river and ocean pollution, and a host of other ills.

Its significance is so important today because food production for more than half of the world's people can only be guaranteed with the aid of nitrogen fertilizers.

Wang's research group designed a five - metal catalyst based on these high - entropy - alloy nanoparticles and demonstrated superior catalytic performance for selective oxidation of ammonia to nitrogen oxide, a reaction used by the chemical industry to produce nitric acid, an important chemical in the large - scale production of fertilizers and other products.

Crops that produce more nitrogen will require less fertilizer, thus lowering production costs and reducing the potential for runoff that can impact the environment, according to Subramanian.

Manmade production of ammonia and nitrate fertilizers has exploded in recent decades and now vastly exceeds the amount of atmospheric nitrogen converted into reactive nitrogen by microbial organisms around the world.

The need to address uncertainties applies to other areas the analysis as well, and we urge you to evaluate the increasing use of nitrogen fertilizers and herbicides associated with greater biofuel production.

This fast decomposition also limits the amount of nitrogen that can get absorbed by crop roots and requires farmers to apply more fertilizer to boost production.

In the chemical toxin category, perchlorate (a naturally occurring chemical, but also a man - made contaminant stemming from production of nitrate fertilizer with certain types of ore serving as the nitrogen source) and tobacco smoke (which contains hydrogen cyanide that can be converted into thiocyanate) are well - researched examples of chemical toxins that are considered goitrogenic because they can interfere with thyroid function.

An agronomist with the company reported to us that their main interest in such fertilizers was for applications in developing and / or tropical countries, where present use of nitrogen fertilizers is, in many cases, relatively inefficient (e.g., rice production).

«Farmers already manage fertilizer to avoid large nitrogen losses, but they are often reluctant to further reduce fertilizer use because they fear doing so will decrease valuable crop production,» said Phil Robertson, principal investigator and Michigan State University professor of plant, soil and microbial sciences.

95 The case for crop - based biofuels was further undermined when a team led by Paul Crutzen, a Nobel Prize — winning chemist at the Max Planck Institute for Chemistry in Germany, concluded that emissions of nitrous oxide, a potent greenhouse gas, from the synthetic nitrogen fertilizer used to grow crops such as corn and rapeseed for biofuel production can negate any net reductions of CO2 emissions from replacing fossil fuels with biofuels, thus making biofuels a threat to climate stability.

The United States Department of Agriculture (USDA) prohibits synthetic nitrogen fertilizer in organic production and encourages natural compost.

Oil is either there or it isn't — while corn production is built on a tripod of water and weather; resistance to plant disease, blight, and pests; and the availability of synthetic nitrogen fertilizers.

Most agriculture relies upon energy subsidies for transporting crops to market, running farm equipment, and the production of synthetic nitrogen fertilizer, herbicides and pesticides.

Skyrocketing fertilizer costs making up the bulk of recent increases in wheat production costs, and the cost of fertilizers is largely tied to the cost of natural gas (production of nitrogen - based fertilizers consumes a considerable amount of natural gas).

Ways to reduce fossil fuel inputs to food systems include the use of farm machinery powered by renewable electricity or farm - produced biofuels; the localization of food systems to reduce transport (perhaps entailing vertical urban agriculture); the adoption of organic and ecological production practices to reduce the need for nitrogen fertilizer, pesticides, and herbicides; and an overall reduction in the consumption of highly processed foods.

Second, the rapid and large - scale exploitation of fossil fuels [4]-- a vast stock of nonrenewable resources accumulated by Nature over hundreds of millions of years that are being drawn down in just a few centuries — and the invention of the Haber — Bosch process to use natural gas to produce nitrogen fertilizer [5,6] enabled increasingly higher levels of food and energy production.

In the U.S. too much nitrogen fertilizer is used and this is bad from the standpoint of global warming, but this is a separate issue from the production of biofuels.

Simply feeding all those people will require doubling agricultural production if their diets are improved with a bit more meat as the fish in the oceans will be long gone and that's all supposed to happen without tractors powered by fossil fuels and nitrogen fertilizers from NatGas.

Saskferco further strengthens Yara's scale and position in North America and is a perfect complement, bringing efficient production capacity from a world - class nitrogen fertilizer facility that is in close proximity to one of the key global fertilizer markets.
