Researchers in the U.S. launch five-year soil health survey

,
Four U.S. universities are launching a massive soil analysis project. The initiative aims to counter land degradation which is estimated to cost $67 bn a year in America

A new project will monitor global nitrogen emissions from fertilizers

,
The Global Research Alliance initiative aims to increase the availability of data on the impact of fertilizers on the Planet. And to better assess the effectiveness of mitigation practices

Can soil fungi counteract climate change?

,
Fungi appear to accelerate plant growth by promoting CO2 removal. A Texas company wants to explore this potential in the market for emission credits

Loss of urban biodiversity is a threat to human health

,
Loss of microbial biodiversity in degraded soils, which is particularly prevalent in cities, promotes the spread of bacterial pathogens and antibiotic resistance, says an international study. Restoring green spaces, by contrast, creates a biological barrier to their spread

Soil transplanting allows regeneration of degraded lands

,
Transferring a healthy soil mass to a degraded area can ensure rapid restoration, explain researchers at the Netherlands Institute of Ecology. An important finding in the global scenario. But more studies are needed
In the U.S., the area affected by wildfires each year has more than tripled in the past 40 years. Photo: Eric Coulter Bureau of Land Management California Public Domain Mark 1.0Eric Coulter Bureau of Land Management California Public Domain Mark 1.0

Soil analysis can help prevent wildfires

,
Wildfires can be predicted through soil moisture assessment. But data collection in the field is not always easy. A group of US researchers is trying to solve the problem

In Canada, science and traditional practices help protect soil health

,
A University of Saskatchewan project aims to create soil health workshops with Native communities and farmers. By encouraging input reduction and diversification of crops and landscapes
Peptides produced by bacteria can target plant pathogens without harming the soil's useful microbiome. Photo: Pxhere CC0 Public Domain Free for personal and commercial use No attribution requiredPxhere CC0 Public Domain Free for personal and commercial use No attribution required

Dutch researchers bet on bacteria to reduce pesticide use

,
Researchers at the University of Wageningen in the Netherlands will study the potential of bacteria to fight plant pests without damaging the soil ecosystem. Crucial is the action of peptides, biodegradable proteins produced by the microorganisms

Central Asia will keep on suffering from agricultural drought for a long time

,
Chinese researchers believe that soil drought linked to climate change can no longer be offset by weather cycles. A challenge for the region's crops and economy
At current rates of extraction, phosphorus production is expected to reach its peak around 2050. Photo: Mick Crawley Attribution-ShareAlike 2.0 Generic (CC BY-SA 2.0)Mick Crawley Attribution-ShareAlike 2.0 Generic (CC BY-SA 2.0)

Global agriculture must reduce its dependence on phosphorus

,
Half of the available phosphorus in the soil comes from mineral fertilizers. Europe, Asia and North America show the highest concentrations. French researchers, "We need to accelerate the agroecological transition in rich countries by allocating the remaining resources to the global South"
