Web-based nutrient management in organic farming (WebMan)
Project
Project code: 2818OE051
Contract period: 01.02.2019
- 31.01.2022
Budget: 238,613 Euro
Purpose of research: Applied research
Keywords: organic farming, nutrient managment, fertilizer requirements, rotation plan
An overall concept for fertilization and nutrient management at farm level will be developed in order to provide recommendations for fertilizer application in organic farms. At ZALF, in addition to the participation on the overall concept, the existing crop rotation planning tool ROTOR will be further developed, modulated with the web-based nutrient management system (adjustment of model parameters and algorithms) and cross-linked (data exchange). One development focus is the applicability of ROTOR under differentiated soil and climatic conditions. ROTOR supports the integration of legumes (symbiotic N2 fixation, N-transfer to following crops), organic and mineral fertilization into organic crop rotations and will allow an economic evaluation. ROTOR included / planned algorithms (eg, yield calculation, symbiotic N2 fixation performance, C-N, P and K balancing, weed management risks, phytosanitary restrictions, and gross margin calculation) are being supplemented or revised to broaden their applicability to relevant arable land adjusted with the project partners and integrated into a revised version of ROTOR. In addition, a) an interface to the organic farming revised BESyD will be established to facilitate the practical application of both tools; and b) partial aspects of ROTOR for crop rotation assessment will be integrated into the prototypes of the decision support system. The algorithms and parameters are continually tuned with the software developers, with the calculation model for whole farm and inter-farm level nutrient cycles as well as with the crop rotation planning tool ROTOR with the aim of the best possible compatibility. The test results are incorporated into adjustments of ROTOR. After developing the software tools, their testing in practice and the introduction of the consulting tools into practice are accompanied by workshops, recommendations for action and consultant training.
