AMES, Iowa – The soil fertility tests farmers have used for decades to measure nitrogen levels don’t account for the vast majority of the nitrogen in soils, so Iowa State University scientists helped ...

Organic nitrogen is important for plant growth, but too much of it can cause a range of problems. Over-fertilization, improper composting, or runoff from nearby agricultural areas can all contribute ...

Nitrogen is often the most limiting nutrient in growing plants. When deficient, plant yields and quality are reduced. However, excessive nitrogen applications could cause concerns in water quality and ...

It’s never too early to prepare for a strong growing season. You don’t have to wait until spring to test your soil quality. Fall soil fertility testing to determine residual nutrients and soil ...

High input prices means farmers will want to be especially judicious about the amount of nitrogen fertilizer they apply on their corn crops this spring. One way that farmers who have regularly used ...

Following a four-year study, North Carolina researchers report that a test accurately predicts nitrogen concentrations in humid soils. Researchers hope that this test will help to reduce under- and ...

The topic of filling a vehicle's tires with nitrogen instead of just plain compressed air is not new. When this option was first available to drivers, it was met with skepticism, but then it just ...

One of the essential nutrients for vigorous crop production is nitrogen. Yet most routine tests done in commercial soil testing labs do not measure available nitrogen in the soil. Soil scientists ...

MADISON, WI, May 4, 2009--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 ...

A team from UNSW Sydney has created a miniature, highly sensitive gas sensor that can detect nitrogen dioxide (NO₂) in real-time without needing external power. This sensor, using innovative ...

Precision is key to innovations in the plastics and polymers space. The quality and consistency of polymers directly impact the functionality of these materials, whether this is in everyday items like ...
