Potassium deficiency in agricultural soils is a largely unrecognised but potentially significant threat to global food security if not addressed, say researchers.

Fish exposed to some pesticides at extremely low concentrations for a brief period of time can demonstrate lasting behavioral changes, with the impact extending to offspring that were never exposed firsthand, a recent study found.

New research led by the University of Liverpool highlights issues relating to restoration and reforestation projects across Africa.

Increasing access to water in extremely arid parts of sub-Saharan Africa can help nomadic livestock farmers in the short term. 

Soil moisture can determine how quickly a wildfire spreads, how fast a hill turns into a mudslide and, perhaps most importantly, how productive our food systems are.

Researchers led by University of Tsukuba, based on the internal nitrogen status of a leguminous plant, have discovered peptide factors that function in the shoot and root systems to transport iron into the root nodules colonized by nitrogen-fixing bacteria.

One of the iconic features of drylands is the striking appearance of islands of plants surrounded by bare soil.

A new computational framework developed in collaboration with Oak Ridge National Laboratory scientist Jiafu Mao provides a detailed assessment of ammonia emissions from global croplands and identifies practices that could curb release of the gas.

Using CRISPR technology, researchers succeed in growing tomatoes that consume less water without compromising yield.

Climate change poses a threat to yields and food security worldwide, with plant diseases as one of the main risks.
