In Europe, the agricultural science was evolving rapidly by 1840s, with notable progress made in Germany by Justus von Liebig in Giessen, and the establishment of agricultural experiments of Rothamsted in England in 1843 by John Bennet Lawes and Gilbert Henry. Your sample and agricultural societies were flourishing. Numerous papers and periodicals were directed to farmers. Agricultural schools, if not common, had been established in the majority of European countries.

Thus, a small minority of young farmers and landowners, had received an education in their profession, while trained farmers purpose they were available to be hired as agents of the property or the teachers. Many of the more progressive landowners employed agents to travel around their farms to urge improved methods of their tenants. As the main element, it was necessary to create agricultural extension, this germ services, they were already present in France, Germany and United States. In Latin America and the Caribbean, the majority of national agricultural extension agencies had its beginnings in the mid-1950s, having been established some few to late 1940s and others at beginning of 1960s. The experience of Asia and Oceania was analogous to that of Latin America and the Caribbean, except that the central period was around 1960. Moreover, the countries of the third world had few faculties of Agronomy or agricultural universities when they achieved independence, in almost all countries the agricultural extension was attached to the Ministry of agriculture, and not a Faculty of Agronomy as it did in the United States.
