Samenvatting

The factors that can influence development, growth and agricultural production in quantity and quality are constantly being explored.High-value crops such as potatoes (Solanum tuberosum L.) are good candidates for the adoption of precision agriculture due to their particularly high production costs. The amount of fertilizer required fuels the permanent challenge of finding the specific fertilization optimization for each agroecosystem. Modeling provides a toolkit fordecision support. Regarding to fertilization, yield is usually related to variable rates of fertilizer, which help predict the optimal rates of fertilizer required. The producer can then see the consequences in terms of yield and income, of increasing or decreasing his inputs under different seasonal conditions. Fertilizer recommendations are made according to the type of production, the bioavailability of nutrients in the soil and, for certain crops, the textural group of the soil surface layer.
