2.4.2. Spatial Implementation

Soil, meteorological and digital terrain maps were used for the spatial implementation of the soil biomass productivity model, i.e., to produce soil productivity maps. The developed model provides productivity indices on a scale of 1 to 100 for several combinations of climate and soil properties in the country. Basic input layers for the spatial implementation include detailed (100 m) soil type and soil property maps and climate data. Slope correction coefficients (see Appendix A Table A1) from the previous official Hungarian land evaluation model [49] were applied to produce the final productivity indices. The coefficients reflect the effect of slope angle and slope direction on productivity. The SRTM digital topographic data were used to implement the correction coefficients and to produce the final maps. Presentation of the results covers all cropland areas of the country at a 100 m resolution.
