Última BIOSTIMULATION OF AGRICULTURAL BIOBEDS WITH NPK FERTILIZER ON CHLORPYRIFOS DEGRADATION TO AVOID SOIL AND WATER CONTAMINATION J. Soil Sci. Plant Nutr. Tortella,G.R; Rubilar,O; Cea,M; Wulff,C; Martínez,O; Diez,M.C. Degradation of the insecticide chlorpynfos (160 a.i mg kg-1) using a biomix of a biobed system biostimulated with inorganic fertilizer (NPK) was investigated. Three concentrations of the fertilizer (0.1%, 0.5% and 1.0% ww-1) were evaluated on chlorpynfos degradation, TCP (3, 5, 6-trichloro-2-pyrinidol) accumulation and biological activity of the biomix. The chlorpynfos was dissipated efficiently (>75%) after 40 days of incubation and no additional dissipation was obtained with increasing concentration of NPK after 20 days of incubation. TCP accumulation occuned in all evaluated NPK concentrations and its concentration increased with the increment of NPK addition raising the probability of leaching of this compound. Biological activity (FDA and... Tipo: Journal article Palavras-chave: Chlorpyrifos; Bio stimulation; NPK fertilizer; Biobed; Andisol.

Tetrachne dregei, Panicum coloratum and Eragrostis curvula are perennial forage C4 grasses, introduced from South Africa to the pampean semiarid region. This work was carried out to compare water stress tolerance; forage production and quality of T. dregei, P. coloratum and E. curvula. Studies were conducted under greenhouse and field conditions. In the greenhouse, watering was stopped after eighty one days of plant emergency in the water stress treatment. Water potential (ψ), stomatal resistance (SR) and shoot and root weights were evaluated. Under water stress, ψ diminished earlier and SR increases were higher in P. coloratum than in T. dregei and E. curvula. Plant survival in T. dregei and E. curvula was higher than that of P....
