Water and sand: is groundwater-based farming in Jordan's desert sustainable? por Naber, M.A., Molle, Francois

“…This paper is based on field work in two locations of Azraq groundwater basin [around the Azraq oasis and in the northern part (Mafraq)], and first presents farm typologies which show the variability of farm gross margins and the contrast between the two zones. While Mafraq stands for capital-intensive fruit-tree cultivation on legal land/wells, Azraq's agriculture is largely based on olive cultivation and wells that are either illegal or granted permits with higher block tariffs, and has a return that is only one tenth of Mafraq's. …”

Land use effects on soil fertility and nutrient cycling in the Peruvian High-Andean puna grasslands por Rolando, J.L., Dubeux, J.C., Ramírez, D., Ruíz Moreno, M., Turin, C., Mares, V., Sollenberger, L., Quiróz, R.

“…Comparisons were made between native grasslands and two alternative farming systems; the first was a system in which native grassland was replaced by an annual cash crop, maca (Lepidium meyenii Walp.), followed by a long fallow and the second was a long-standing perennial cultivated pasture. There was greater N mineralization, extractable Bray-1 P, and K+ in recently converted maca soils relative to adjacent native grassland soils most likely caused by tillage-induced nutrient mineralization and by incorporation of manure and native grassland residue during the first year of land preparation prior to planting maca. …”
