| The purpose of this study is to precise the conditions of agricultural reclamation of tepetate in the eastern part of the Mexico valley (Texcoco). The Tepetate is a compact and sterile material. The lack of nitrogen, carbon and the poor biological activity limit the possibility of plant development. But after the use of heavy machinery and terracing, it is possible, under certain conditions, to use this new soil for agriculture. From 1993 until 1996, we compared native soil and different treatments applied to the tepetate reclaimed, such as the deepness of the reclamation, the use of chemical/biological fertilisers, the mono-culture/associated cultures, the tillage practices of the new soil on 6 different terraces of 700 m2. One of our goals was to find... |

| The reclamation of volcanic indurated soils called tepetates in Mexico must control soil erosion and generate a good productivity of these new soils according to a sustainable development strategy. This paper shows the results of an european research program involving ORSTOM and the Colegio de Postgraduados en Agrociencias in the eastern part of valley of Mexico (Texcoco). Different systems of culture have been studied (mono/associated culture, with/without manure, soil/tepetate, natural/cultivated tepetate, tepetate with deep/normal subsoiling, tillage practice) during four years on 8 large terraces (700 m2). After every rain, we measured the runoff, took and dried all the sediments, sampled water and followed the vegetation cover, the soil surface... |
