Prescriptive–corrective nitrogen and irrigation management of fertigated and drip-irrigated vegetable crops using modeling and monitoring approaches

The combined use of fertigation and drip irrigation to frequently apply small amounts of N throughout a crop provides the technical capacity for precise N and irrigation management. A prescriptive–corrective management (PCM) package, based on modeling and monitoring approaches, was developed for combined irrigation and N management to take advantage of this technical capacity in a greenhouse-based vegetable production system. For irrigation, the...
