ABSTRACT
Maceiras or fields of maceira constitute a form of agriculture unique in the world, and can even be said to be indigenous to Minho, north of Portugal. This form of agriculture, widely used on the coasts of these two countries, was invented; it is said, in the 18th century by the Benedictine monks of the abbey of Tibaes. The principal function of the boat was similar to that of an ox cart, plow or other agricultural equipment, but the boat also served to transport goods, foods, people and livestock within the Ria de Aveiro. One of the interesting and important features of the agriculture of the Channel Islands, and particularly of the agriculture of Jersey before 1900, was the use of seaweed as fertilizer. A habitual feature of the agricultural scene, seaweed was the cause of much litigation and legislation in Jersey, largely because of its supreme value when applied to the sandy soils that cover most of the island.
