Marine bacteria may serve as a natural soil fertiliser

,
A Japanese study tested the effectiveness of purple non-sulphur bacteria in providing nutrients to plants. Thanks to their enzymes, these microorganisms take nitrogen from the atmosphere and then incorporate it into proteins

Second edition of the General States of the Soil at Ecomondo in Rimini. Dozens of experts attended to discuss the best strategies capable of bringing organic carbon back into degraded soils and reducing CO2 in the atmosphere
Secondo la FAO la domanda globale di pellicole in plastica per uso agricolo raggiungerà quota 9,5 milioni di tonnellate nel 2030 contro i 6,1 milioni del 2018. Foto: Florian Gerlach Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0)

Polyethylene mulches leave behind ‘negative effects for decades’

,
L’ampio utilizzo delle pellicole da pacciamatura nelle colture di fragole si traduce nella dispersione di micro e macro frammenti di plastica nel suolo. Un fenomeno, rivela uno studio californiano, i cui effetti possono manifestarsi per decenni

Toilets may provide an alternative to chemical fertilizers

,
By recycling human manure it is possible to produce natural fertilizers that provide identical yields as chemical equivalents, a German research has found. No risk of drug contamination, the authors explain. But further studies are needed

Plastic, glass, metals: the “enemies” that dirty the compost

,
The alarm emerges from a series of video interviews with managers of composting plants carried out by the italian Biorepack consortium. Too high percentages of "foreign fractions" (up to 12%) make it more difficult and expensive to make compost. On the other hand, compostable, flexible and rigid bioplastics were promoted with flying colors: "very useful for increasing quantity and quality of the final product"

Soil and compost management can help Europe achieve climate neutrality

,
In Europe, 31.7 percent of total organic carbon stocks are found in agricultural soil. Some good practices, such as the use of compost, can increase carbon sequestration while encouraging yields, says a report by EU Parliament
