Nitrate in the groundwater poses a challenge on intensive arable farmland. A simple new table-based tool helps extension services in the Niederbipp-Gäu-Olten Nitrate Project calculate the nitrogen requirement of arable crops with greater precision and ease.
Camera-guided spot-spraying enables a targeted application of plant protection products (PPPs) on individual plants. Field trials confirm that this can result in PPP savings and a significant reduction in runoff and drift.
How reliable are modern methods of measuring nitrogen fertilisation in vegetable production? Field trials show that established methods are still more effective – and reveal scope for reduced fertilisation without yield loss.
