Our long term experience in the ~23.5 ha research field since 2001 shows that decision support requires complex databases from each management zone within that field (eg. soil physical and chemical parameters, technological, phenological and meteorological data). In the absence of PA sustainable biomass production cannot be achieved. The size of management zones will be ever smaller. Consequently, the on the go and remote sensing data collection should be preferred.  The paper presents the results of ECa and near-surface hyperspectral measurements. For the increase in accuracy of yield prediction of DS models the energy input-output analysis in the management zones can also be used.
