Algorithms drive irrigation in smart agriculture

,
In an attempt to make irrigation more efficient, Stanford University has developed a new and more accurate system for calculating evapotranspiration. Measurement is shortened by 100 times
Nitrogen, contained particularly in fertilizers, produces variable effects on plants and soil microfauna. Photo: Michael Trolove Attribution-ShareAlike 2.0 Generic (CC BY-SA 2.0)Michael Trolove Attribution-ShareAlike 2.0 Generic (CC BY-SA 2.0)

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

Canadian researchers start a soil carbon measurement project

,
An annual project in the state of Saskatchewan will collect data on soil carbon occurrence. The goal is to assess soil effects and generate measurable and verifiable emission credits
The decline in pollinating insects has negative effects on the availability and price of healthy foods such as nuts, legumes, fruit and vegetables, causing an increase in premature deaths. PHOTO: Pixabay

500,000 deaths a year linked to the decline in pollinators

,
The "prudential" estimate is contained in a new international study published in Environmental Health Perspectives. Premature deaths are thought to be caused by decreasing availability and rising prices of healthful foods, which are in turn linked to the global decline of bee and pollinators
Between 2010 and 2018, commitments made by companies to tackle deforestation in the Brazilian Amazon ensured the protection of about 7,000 square kilometers of forest. But it could have been 24,000.

Cattle-related deforestation in the Amazon could have been halved

,
If anti-deforestation agreements had been fully implemented, 24 thousand km2 of land could have been saved in the Amazon compared to the 7 thousand actually protected between 2010 and 2018, according to a study from U.S.

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
The application of statistical models in combination with spectroscopy makes it possible to assess the concentration of different elements in the soil. Photo: Marco Verch Attribution 2.0 Generic (CC BY 2.0)Marco Verch Attribution 2.0 Generic (CC BY 2.0)

Spectroscopy offers new opportunities for soil analysis

,
A research from the University of Katowice opens new perspectives in the field of soil analysis. Through spectroscopy, researchers were able to determine the presence and concentration of key elements in soil
Biochar is especially useful in limiting the effects of soil salinization. A phenomenon which is prevalent in Bangladesh where about one-third of agricultural land is in coastal areas.

Biochar provides relief for saline soils in Bangladesh

,
Biochar promotes tomato crop yields in salt-affected soils, a research conducted in Bangladesh has found. Effects on carbon sequestration are also positive

“China must change direction in its anti-desertification strategy”

,
The actions promoted in China in the 21st century have reportedly produced limited benefits, a recent study finds. Among other things, Beijing's "Grain for Green" plan has decreased the incomes of farmers and herders. Other natural factors have mainly weighed on land regeneration

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
