Transfer mulch in organic greenhouses

In organic greenhouses, crop rotations are generally intensive and lack diversity, green manures are rare, and production relies heavily on external inputs. Consequently, problems like soil salinity, nutrient imbalances and crop damage from pests and diseases are common. In the Greenresilient project the use of transfer mulch is applied as an ‘innovative’ method and is tested and analysed to determine whether the practice is beneficial for soil health and biodiversity. This article explains the benefits, risks and challenges of transfer mulch, and provides recommendations for practical application
