What is the right amount of nitrogen in agriculture? Not enough contributes to hunger, too much damages the environment

Nitrogen is essential in crop production, but it comes with a caveat: Use too much of it, and you risk polluting the environment; use too little, and you risk limiting your crop yield. This was also the focus of an article that appeared in the journal Nutrient Cycling in Agrosystems. The paper, led by researchers from […]

Nitrogen use in global agriculture varies widely, affecting the food supply

An article in the journal Nutrient Cycling in Agroecosystems discussed the efficient use of nitrogen in agricultural production systems. The authors used selected papers from the 19th Nitrogen Workshop held in Sweden in 2016. Nitrogen is an essential input in crop production, and its economic significance has been established for over a century. There are two main […]

Effects of nitrogen, phosphorus and potassium on the nutrition of field fava beans (Vicia faba L.)

The health of the soil upon which crops are planted can directly affect the health of the crops themselves. But the extent to which certain soil minerals can affect nutrients that aid in plant growth isn’t so clear-cut. Now a research study looks into identifying the actual effects of specific minerals, namely nitrogen (N), phosphorus […]

Big Ag is using more synthetic fertilizers, and the nitrogen is causing dead zones and algal blooms in our waterways

With more nitrogen flooding our waterways, creating algal blooms and dead zones, scientists have warned that the use of synthetic fertilizers should be significantly reduced. In a seminar room at New York University in January, nitrogen experts from around the world painted a picture of how a nitrogen-soaked planet would appear. The group conducted the […]

Cover crops found to reduce weed infestations, need for tillage while returning nutrients to the soil

A study that was published in the journal Agriculture, Ecosystems & Environment found that utilizing cover crops could help in reducing the need for tillage, increasing soil fertility, maintaining yield, and managing weed growth problems. (Source: Science.news) A three-year experiment in Switzerland had researchers studying eight cover crop treatments, which were cultivated for a short two-month […]
