On December 18, 1818, the Nassau state government commissioned Wilhelm Albrecht to establish the Agricultural Association. The government also drafted the statutes and determined the group of members. The founding meeting took place in Idstein on April 18, 1820.

The purpose of the Agricultural Association was, among other things, to expand agricultural knowledge and improve agriculture, viticulture and animal husbandry. The agricultural association was divided into the departments of field and meadow cultivation, viticulture and fruit growing as well as horticulture, livestock breeding and livestock refinement.

It had been based in Wiesbaden since 1834. Its first secretary was Wilhelm Albrecht, editor of the Landwirtschaftliches Wochenblatt für das Herzogtum Nassau since 1819. The publication had been published by the Landwirtschaftlicher Verein since 1849, which changed its name to Verein Nassauischer Land- und Forstwirte in 1850. In 1835, independent district associations were established at the level of agricultural districts, which from 1849 formed the "Gesamtverein der Land- und Forstwirthe im Herzogtum Nassau". The establishment of the Chamber of Agriculture in 1896 deprived the Agricultural Association of its original mandate to a large extent. From then on, the president of the chamber and the chairman of the association were identical, and in 1897 the journal was renamed Amtsblatt der Landwirtschaftskammer und Zeitschrift des Vereins nassauischer Land- und Forstwirte.

From the 1920s onwards, efforts by other agricultural organizations to influence the Landwirtschaftlicher Verein and, above all, its assets could be observed. As a result, the articles of association were amended in 1921 and, following the sale of the Geisberg farm in 1924, the "Hof Geisberg Foundation" was established in 1926/27. In 1933, the Landwirtschaftliche Verein was dissolved in the course of the so-called Gleichschaltung.
