A new tool to assess nitrogen and phosphorus flow in agriculture

MITERRA-EUROPE is a new tool that models the amount of nitrogen and phosphorus, among other key pollutants, used in agriculture across all 27 Member States at regional, country and EU-27 levels. It can be used to calculate the effects of different strategies to minimise excess pollution. Many regions in the EU-27 use more nitrogen and phosphorus in agriculture than is required. The main sources ...

Nitrogen applied

Combating soil erosion is a primary concern for agricultural producers in the United States, and many have incorporated conservation tillage systems in their effort to maintain a profitable crop output. Cover crops are an important tool in this cycle, and while it is known that using nitrogen fertilizers can increase these crops biomass, the resulting levels of nitrogen for the following cash ...

Soil nitrogen test measures microbial nitrogen

Contrary to the prevailing view, cereal crops derive the majority of their nitrogen from the soil, not fertilizer. Soils differ considerably in microbial activities that determine nitrogen-supplying power, and these differences must be taken into account if nitrogen fertilizers are to be used efficiently. The Illinois Soil Nitrogen Test (ISNT) was developed for this purpose, and involves ...

Dangerous nitrogen pollution could be halved

The most important fertilizer for producing food is, at the same time, one of the most important risks for human health: nitrogen. Chemical compounds containing reactive nitrogen are major drivers of air and water pollution worldwide, and hence of diseases like asthma or cancer. If no action is taken, nitrogen pollution could rise by 20 percent by 2050 in a middle-of-the-road scenario, according ...

Nitrogen recommendations based on crop reflectance

Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

Agricultural Bacteria: Blowing in the Wind

It was all too evident during the Dust Bowl what a disastrous impact wind can have on dry, unprotected topsoil. Now a new study has uncovered a less obvious, but still troubling, effect of wind: Not only can it carry away soil particles, but also the beneficial microbes that help build soil, detoxify contaminants, and recycle nutrients. Using a powerful DNA sequencing technique, called ...

Nitrogen Management Studied in Greenhouse Pepper Production

As consumer demand for year-round fresh produce increases, vegetable and fruit producers are facing significant environmental and sustainability issues, and are being challenged to examine traditional production practices in order to improve product quality while limiting environmental impact. A recent focus on both the positive and negative effects of nitrogen applications has researchers across ...

Less nitrogen could increase profit & sustainability

More fertilizer doesn't always mean more profit. That's one conclusion from a 10-year study conducted by Agricultural Research Service (ARS) scientists at the agency’s Soil Plant Nutrient Research Unit in Fort Collins, Colo., and colleagues at Colorado State University. From 1998 to 2008, the researchers evaluated and compared potential management strategies for reducing nitrogen and nitrate ...

Straw residue helps keep nitrogen on the farm

Scientists are exploring ways to reduce non-point pollution from agriculture. A new study finds that using straw residue in conjunction with legume cover crops reduces leaching of nitrogen into waterways, but may lower economic return. Agriculture is the largest source of nitrogen non-point pollution to waterways in the United States, flowing into streams and rivers via erosion from farmlands, or ...

In-crop nitrogen key to summer sorghum yields

With the summer cropping season on our doorstep, growers are weighing up their planting options against the market, seasonal conditions and gross margin calculations. For many the summer cropping rotation will include sorghum and maximising crop yield and profitability will be a key driver of all pre-plant and in-crop agronomic decisions. Recent research funded by the GRDC, Queensland Alliance ...

Forest fires help power the nitrogen cycle

When fire burns down a forest, nitrate levels go up, and the effects are persistent, according to recent research from University of Montana scientists. They found that charcoal deposited during fire events has the potential to stimulate the conversion of ammonia to nitrates, an important step in the nitrogen cycle. Led by Patrick Ball, the research team found that a type of bacteria that ...

Irish agriculture faces emissions dilemma

Ireland is facing a classic conflict, pitching economic growth targets against the need for action on climate change. On one hand, Ireland’s planners want to see significant growth in its food and agriculture industry – a sector that is one of the main pillars of the country’s economy, accounting for about 8% of gross domestic product. On the other hand, the country − ...

Diversifying crops `could green African agriculture`

The biodiversity of crop fields could be key to a greener revolution in Africa, where ecosystems are degrading and crop yields are stagnating, says a study conducted in Malawi. African farmers could halve their fertiliser use and still get the same yields, the study found, with less year-to-year variation in yields and with as much as 70 per cent more protein in grains — by simply rotating ...

New strategy aims to reduce agricultural ammonia

As concerns about air pollution from large dairies and other concentrated animal feeding operations (CAFOs) continue to mount, scientists are reporting a practice that could cut emissions of an exceptionally abundant agricultural gas—ammonia—by up to 30%. In the May-June 2011 issue of the Journal of Environmental Quality, a team led by Mark Powell, a soil scientist with the USDA ...

Nitrogen fertilizer works way into sea and destroys marine habitats - EC

Substantial increases in the flow of nitrogen into the sea have raised concerns about marine pollution. New research shows that commercial fishing is playing an important, but now declining, role in transferring this nitrogen back onto land. Enormous amounts of nitrogen fertilizer are applied to agricultural land to increase crop productivity. However, the use of such fertilisers can be damaging ...
