• 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

History and position of ALTIC

What can ALTIC offer you?

• 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•

Why fertilizing?

Soil solution

Many functions, for example:

• Component of chlorophyll• Strength of cells• Stimulating root development

Functions of nutrients

Plantroot

Nutriënts on soil (clay and organic matter)

Soil sampling and analysisSampling

Sample must be representative for:• Part of the field (not too big)• Area where the crop will grow

Sample is representative:• With a big amount of sample points• Good homogeneity of the field

Soil sampling and analysis

• Soil (laboratory/soil scan)• Plant (laboratory/sensor technology)

Different maps

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

• 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
