Excess nitrogen also impacts soil invertebrates and insects

A Dutch meta-analysis of 126 studies conducted worldwide illustrates the consequences of nitrogen accumulation for soil microfauna. Effects vary across species. Climate factor

Can seed carriers help regenerate the soil?

Created by researchers at Carnegie Mellon University, seed delivery devices pave the way for soil regeneration. But some observers are skeptical

From India to Australia: the bauxite paradox

In India, the mining of bauxite, a rock needed for aluminum production, takes land away from agriculture, producing permanent soil damage. But this same resource, paradoxically, may carry with it a solution

Soil moisture is a key factor in predicting droughts and floods

According to a study from U.S., variation in soil moisture is the crucial factor in understanding extreme phenomena such as droughts and floods and Overcoming uncertainty related to climate change
NRM analyzes of thousands of soil samples taken from UK farmland have shown deficiencies in magnesium, phosphorus and potassium. PHOTO: Steven Weeks on Unsplash

UK, two thirds of soils show nutrient deficit

An analysis by the independent laboratory NRM: as a result of the degradation, wheat crops show 10% less nitrogen and 25% less phosphorus. Thousands of soil samples extracted from UK farmland
In Canadian forests, increased tree species diversity produces growth in soil carbon and nitrogen. Photo: Lawrence Hislop Attribution-NonCommercial-ShareAlike 2.0 Generic (CC BY-NC-SA 2.0)Lawrence Hislop Attribution-NonCommercial-ShareAlike 2.0 Generic (CC BY-NC-SA 2.0)

Variety of trees promotes carbon and nitrogen sequestration

An increase in the number of tree species stimulates greater carbon and nitrogen sequestration, Canadian research explains. But biodiversity is in decline. Promoting it means mitigating climate change and reducing land degradation

Flash droughts are becoming the new normal

In six decades, flash droughts have increased in 74 percent of the Planet's regions, says a Chinese study. Climate change remains the main critical factor
