The introduction of soybeans to the southern and eastern parts of Paraguay in the early 1970s, followed by wheat in the mid-1970s, using conventional mechanised soil preparation practices with disc ploughs and harrows, initiated a process of widespread soil degradation and erosion. The technique of no-tillage was first used in Paraguay in the late 1970s. Following a slow start, its adoption by Paraguayan farmers gathered momentum increasing from 20,000 ha in 1991/92 to an impressive 250,000 ha in 1995/96, accounting for about 19% of the land cultivated mechanically.
