USO DE ACONDICIONADORES ORGÁNICOS Y BIOPOLÍMEROS PARA BIORREMEDIACIÓN DE SUELOS SALINOS-SÓDICOS DE LA LLANURA DE CORO, FALCÓN, VENEZUELA* Use of organic conditioner and biopolymers in biorremedy of saline-sodic soils of Coro plain, Falcon, Venezuela

To evaluate the effect of organic and biopolymers conditioners on chemical and biological properties a soil sodium-salt from Cebollal of Coro, six treatments were considered: without application of conditioner (T1), cactus data (Stenocereus griseus (Haworth) Buxb) extract (T2), Spain Tuna (Opuntia ficus-indica) extract (T3), vermicompost (T4), biopolymers biosol (T5) and desalt (T6). Conditioners were applied to the soil in liquid form at a concentration of 20 g L- 1 , and the soil was incubated for 45 days with measurements of basal respiration, pH, electrical conductivity, exchangeable cations and exchangeable sodium percentage at 7, 15, 30 and 45 days. The results showed a decrease in the values of electrical conductivity and exchangeable sodium in relation to baseline values on the ground. Also, it found that basal respiration
