Anja van der Salm, director • Jan Ties Malda, account manager • Viktoria Dorka, scientific researcher
LABORATORY RESEARCH CENTRE • Fertilizing advice • Fertiliz(er)(ing) research • Crop monitoring • Precision agriculture • Soil analyses • Plant analyses • Water analyses
www.altic.nl Location De Drieslag 30 8251 JZ DRONTEN
Historyandposition of ALTIC • Founded in 1992 as independent research center by the agricultural university Dronten and agricultural advice organizations • Knowledge development by research as supporting system for educational goals • Needs for new fertilization advices by different crops • Legislation in The Netherlands about N and P2O5 makes it necessary to evaluate the existing advices very critical • Farmers need accurate and actual supporting information to make good agricultural practice • More and more information is geo-based research and specific products
ALTIC connected with education • By government agreed teaching organization • Regularly placement students at ALTIC • ALTIC organizes trainings at colleges and universities (PTC+/CAH/WUR) • Courses for agricultural specialists, advisors and farmers • Writing educational materials about fertilization and precision agriculture
Whyfertilizing? The law of Liebig Mg Mn B Ca K N Zn Fe minimum P
Plant root Functions of nutrients Many functions, for example: • Component of chlorophyll • Strength of cells • Stimulating root development Soil solution Nutriënts on soil (clay and organic matter)
Soil sampling and analysis Sampling • Sample must berepresentativefor: • Part of the field (nottoo big) • Area where the cropwillgrow • Sample is representative: • With a big amount of sample points • Good homogeneity of the field
Sensingandlaboratory • Soil (laboratory/soil scan) • Plant (laboratory/sensor technology)

Different types of maps • Lutum (clay content in the soil) • Sand fraction • Organic matter content • Hydrological properties (water retention) • Height map with 2 cm accuracy
Management maps • Management map for variable dosage: • compost • fertilization • soil herbicides • plant/ seed distances • water dosage
Goals of ALTIC in Leonardo • Sharing knowledge, increases knowledge • Looking for possibilities for working together • Translate our experience into educational materials • The specific content belongs to the Hungarian situation and the regional possibilities • Simple tools for precision agriculture • Supported by practical advises about fertilization, crop production and optimalisation
