Lecture: Where the hidden half of the crop meets the hidden half of the soil

Depth and architecture of root systems play a prominent role in crop productivity especially under conditions of low water and nutrient availability. The subsoil often contains high amounts of nutrients that may potentially serve for nutrient uptake by crops including finite resources such as phosphorus that have to be used in moderation to delay their exhaustion. This contribution deals with an overview on our recent research on developing cropping systems that enable better use of water and nutrients from the subsoil. The overall aim is to create and manage large sized biopores in order to enable better access to deeper soil layers, to enhance water and nutrient uptake via biopores formed by roots and earthworms and to deliver also above ground ecological services.
