Quality management

At Hartog, quality is a high priorty; quality is guaranteed through full process monitoring - from sowing to distribution. Many more companies in the agricultural sector find Hartog a reliable partner in controlled production.

Controlled Cultivation

Hartog works closely with carefully selected contract growers - mostly farmers who grow the heavy, calcareous clay soil of the polders around the IJsselmeer. They only grow the varieties selected by Hartog.

At Hartog we harvest our own crops. Thus we can mow at the right time and we are less dependent on the weather forecast for example.

Hartog dries the crops in large, computer-controlled dryers with a combined capacity of 90 tons of water evaporation per hour. This fast drying process ensures each product stays fresh and the taste and smell of the countryside is preserved. The temperature at which we treat our products means that they are free from pathogens such as Paratuberculosis and Salmonella.


Hartog is closely involved with its suppliers and its customers. Our product also requires a good knowledge of the user such as cattle, horse and goat farmers. We pay close attention to the local situation of each individual customer. We not only focus on our direct customers but also to the distributors who have to sell our products in a competitive market.

We are convinced that our policy regarding the quality will lead to a quality that largely gives the assurance that our products and services meet the requirements of laws and regulations relating to the safety of humans, animals and the environment.
