Tra i bioprodotti, i teli pacciamanti sono tra quelli i cui vantaggi sono più tangibili: diversamente da quelli prodotti in plastica fossile, a fine coltura si possono incorporare nel terreno con una semplice trinciatura e non hanno costi di lavaggio, rimozione e smaltimento.

‘Biodegradable plastics do not impact ecosystems’

,
A study in US shows how bioplastics can degrade in an acceptable timeframe and without harming the environment as long as they are disposed of properly

Ultrasound device measures the impact of drought on plants

,
A new device developed by a team of Lithuanian and Spanish researchers allows detection of the alteration produced by drought on certain key parameters of the plant's physiological state
Among weather events, in the Netherlands, drought reduced yield by 24% compared to the average, rain during sowing lowered it by 18%. Photo: Paul van de Velde Attribution 2.0 Generic CC BY 2.0 DeedPaul van de Velde Attribution 2.0 Generic CC BY 2.0 Deed

Two Dutch studies reveal the impact of weather on crop yields

,
The reduction in crop yields following extreme weather events such as drought and heavy rain has been accurately quantified for the first time. Depending on the type of crop and the phenomenon, the decrease ranges between 13 and 36%.
In acidic soils such as red clay soils, the use of rock dust for CO2 capture produces disappointing results.

Rock dust helps capture CO2 but not in acidic soils

,
The dispersion of rock dust in the soil is generally an effective way of storing carbon. But in acidic soils, according to an Australian study, this mechanism does not work

Desertification halves soil functionality in Brazil

,
The calculation is contained in research conducted by two universities in the country, which analysed degraded areas in the north-east of Brazil. A confirmation of the impact of desertification on the soil's ability to sequester carbon

EU proposes three agricultural strategies for ecosystem restoration

,
The European Environment Agency suggests approaches to protect ecosystems and biodiversity: sustainable soil and water management, reconstruction of agricultural landscapes, maintenance and restoration of semi-natural habitats

Climate change may decrease methane sequestration in the Amazon by 70%

,
A study reveals how methane uptake by forest soil in the Amazon decreases sharply under hot and dry conditions. While production of the same gas increases following heavy rains
