Drought is once again a major threat to European agriculture

,
Agricultural drought is affecting northwestern Europe, the Baltic and some eastern and southern regions of the Continent. In contrast, following heavy rains higher yields are expected in Italy, Greece and the Iberian Peninsula

Drones are the new allies of hemp farmers in the US

, ,
Processing of images captured by drones, a study from the University of Florida states, makes it possible to assess the health and growth status of plants by providing guidance on the optimal fertilizer dose
Grasslands are home to a wide variety of plant species and provide numerous ecosystem services, such as carbon sequestration, support for pollinators and grazing for livestock. But they are also some of thh most threatened ecosystems due to human activities, including land use change and intensive agricultural practices.

Study reveals how much nitrogen grasslands can tolerate

, ,
According to researchers, applying more than 80 kg of nitrogen per hectare in a year would make grasslands “functionally poor, highly unstable and vulnerable to extreme weather events”
In 50 years, wheat, corn and barley yields (photo) are 10, 4 and 13 percent lower than they would be under normal circumstances. Photo Dag Endresen Attribution 2.0 Generic CC BY 2.0 DeedPhoto Dag Endresen Attribution 2.0 Generic CC BY 2.0 Deed

Climate change has reduced grain yields by up to 13 percent in 50 years

,
Warmer and dryer weather favors water stress thus impacting the productivity of wheat, corn and barley crops, a study from the Standford University has found. New investments and more accurate predictive models are needed for the future
Using transcriptomics, researchers have found that the responses of roots to soil stress are both genetic and physical.

How plant roots respond to soil stresses

,
A research reveals how roots actively perceive the microenvironment and activate specific molecular responses. From the study, new prospects for more climate-resilient crops

US agriculture pays the price of atmosphere “thirst”

,
An American study introduces the concept of “thirst waves.” In the US they have been on the rise for at least four decades. The phenomenon occurs when evaporative demand is high and plants therefore need more water
An experiment in Wales revealed how bioplastic mulches do not negatively impact soil organic matter content and have minimal effects on the bacterial community. Photo: F.

Biodegradable mulch sheets don’t reduce soil organic content

,
According to a British study, the use of bioplastic biodegradable mulch sheets in agricultural soils increases yields and has no side effects in terms of carbon balance
In Antanarivo, Madagascar, soil extraction has been accompanied by the spread of terrace farming and resilient crops according to a study. Photo: Visiting Madagascar Attribution-ShareAlike 2.0 Generic CC BY-SA 2.0 DeedVisiting Madagascar Attribution-ShareAlike 2.0 Generic CC BY-SA 2.0 Deed

From soil extraction new opportunities for agriculture

,
The production of building materials through soil negatively impacts the landscape but also opens up new possibilities for the development of climate and flood resilient agriculture. A lesson from Madagascar
In the fields treated with three-year cropping cycle nitrogen leakage was reduced by 50 percent. Photo: Daniel Schwen Attribution-ShareAlike 4.0 International CC BY-SA 4.0 Deed

A more diversified rotation can halve nitrogen leakage in crops

,
Nitrogen leakage can be cut in half by applying a three-year crop rotation while soil health also benefits, an American research has found
