Agricultural practices such as soil tillage emit greenhouse gases such as CO2 and N2O. As a consequence, reducing the tillage could both reduce greenhouse emissions and improve soil quality. In Europe about 25 % of arable land is managed under reduced tillage and no tillage, mainly using herbicides to get rid of weeds. Therefore, a major drawback for(More)
This report shows that weed harrowing in organic cereal fields is an efficient alternative to herbicides since weed harrowing does not reduce yields compared to weed-free plots. Arable weeds provide resources and habitat to many organisms. However, weeds are the most important constraint to crop production. Indeed, the potential crop losses of the eight(More)
The global demand for cacao has recently increased. To meet this demand, the cultivated area has been expanded in tropical forest areas and production has intensified by replacing traditional agroforestry systems with monocultures. This has led to a loss of biodiversity in cacao-growing areas. More sustainable production systems such as agroforestry and(More)
