Recycles nitrogen
Organic farming can help reduce nitrogen pollution on a global scale because itrecycles nitrogen,thus creating far less reactive nitrogen than conventional agriculture,according to a new study from The University of Virginia and The Organic Center.

Does organic farming reduce nitrogen pollution?

New research conducted by The University of Virginia and The Organic Center concluded that organic farming not only recycles nitrogen, but it also creates less reactive nitrogen in the environment, which is critical for pollution reduction. The study looked at nitrogen pollution produced by both conventional and organic farms.

Can organic farming reduce water pollution in the Midwest?

A recent study published in Sustainable Agriculture Research has found that organic farming methods can be used to reduce water pollution in U.S waterways. The leaching of nitrate from farming soil into water drainage systems is a major source of water pollution in the upper Midwestern states.

Is organic farming better for the environment than traditional farming?

Both farm circumstances contribute to soil nitrogen loss as a result of the crop systems, but organic farming fared better in preventing nitrogen pollution, preventing three times the amount of reactive nitrogen than traditional farming methods.

Why do organic farmers have to rotate in the soil?

The legumes that organic farmers have to rotate in to help convert nitrogen into more reactive compounds in the soil end up cutting deeply into other food crops they could otherwise grow, the study notes.

Dive Brief

A new study has found that organic farming is much more efficient at recycling nitrogen than conventional farming, helping reduce global nitrogen pollution, New Hope reports.

Dive Insight

Consumers already associate organic products with environmental benefits, and view a lack of fertilizers and pesticides as one of their defining features.

How can organic farming reduce climate pollution?

Organic practices can reduce climate pollution produced directly from farming – which would be fantastic if they didn’t also require more land to produce the same amount of food. Clearing additional grasslands or forests to grow enough food to make up for that difference would release far more greenhouse gas than the practices initially reduce, …

What would happen if half of the land used to meet that spike in demand was converted from grasslands?

If half the land used to meet that spike in demand was converted from grasslands, which store carbon in plant tissues, roots, and soil, it would boost overall greenhouse-gas emissions by 21%. Among other things, organic farming avoids the use of synthetic fertilizers, pesticides, and genetically modified organisms, …

How much does organic farming increase land use?

In addition, a 2017 Nature Communications study estimated that switching to organic farming would increase land use by only 16% to 33%.

Does manure increase carbon?

Separately, the use of manure and longer crop rotations can increase the amount of carbon stored in soil .

Does synthetic fertilizer increase crop yields?

After all, the whole point of synthetic fertilizer is it boosts crop yields, by providing a “fixed” form of nitrogen that promotes plant growth.

How does nitrogen affect the environment?

As the reactive nitrogen moves through the environment , it creates a cascade of detrimental environmental impacts. Excess reactive nitrogen contributes to climate change. Fertilizer can get converted into nitrous oxide, a greenhouse gas 300 times more powerful than CO 2.

What percent of nitrogen is used in food?

The study also found that almost all of the nitrogen used to produce the food in a conventional food-based diet – 93 percent — was newly created reactive nitrogen. In comparison, for an average diet of organic foods, only 33 percent of the nitrogen used to produce the food was new reactive nitrogen. The rest of the nitrogen used …

How much less reactive nitrogen is released from organic production?

The study found that organic production releases 64 percent less new reactive nitrogen to the environment than conventional production. "Since nitrogen is an element, it cannot be created or destroyed," said Dr. Tracy Misiewicz, Associate Director of Science Programs for The Organic Center.

What percentage of nitrogen is used in organic farming?

Organic farms primarily utilize already existing reactive nitrogen: 80 to 95 percent of organic’s inputs are from recycled nitrogen sources. The study found that organic production releases 64 percent …

How is nitrogen transformed into reactive form?

More and more of the benign nitrogen on earth is getting transformed into the reactive form, primarily through the creation of synthetic fertilizer. Agriculture uses a huge amount of reactive nitrogen to grow crops, and much of that nitrogen is lost to the environment during the food production process.

What is the dead zone in the Gulf of Mexico?

Nitrogen runoff pollutes oceans, leading to oxygen loss and killing everything in giant areas called "Dead Zones.". In 2017, the dead zone in the Gulf of Mexico was the size of New Jersey – the biggest ever seen.

What are the environmental issues that affect the planet?

Climate change. Smog. Acid rain. Dead zones. The ozone hole. These are more than environmental buzz words. These are real issues affecting the planet, and nitrogen pollution plays a key role in each of them. Plants need nitrogen to grow, it is essential to life on earth and is present in all living systems.
