80% of farmers in the Netherlands have used GPS systems, supported by satellites provided by the Dutch government. Farmers use them to capture farmland information and conduct scientific analysis of farmland conditions. In addition, farmers also collect field information through drones and other methods. Whether it is a satellite or an unmanned aerial vehicle, through these high-tech means, the amount of information is collected and stored, and the beneficial and harmful behaviors can be distinguished, so as to give more accurate and effective advice and carry out comprehensive pest management.
In facility agriculture, the application of biological prevention and control and natural enemies is very common. The proportion of chemical pesticides used in the Netherlands is relatively small, about 10% to 20%, and the proportion of physical and biological prevention and control is basically 60% to 80%. The organic farming area in the Netherlands accounts for 7.4%, and the Netherlands can achieve a very high yield of 54.4 tons of vegetables per hectare. Many countries in the world are less than one-half of the Netherlands. This fully shows that the land productivity of the Netherlands is higher than that of most countries. This is the prominent gap between high-tech agriculture and traditional agriculture.
