The present trial was carried with the aim to evaluate the effect of a soils bioenhancer and organic fertilizers on the physical and chemical component of quality soil in onion in Majes Irrigation. The trial was carried out in a plot under spray irrigation and splot under drip irrigation, in both plot was stablished the sources and levels from organic fertilizer (Chicken manure and seabird guano) compared against chemical fertilization. A completely random block design was used with 9 treatments and 3 repetitions for each plot, after that it was made a combined analysis to both plots. Effective deep roots and average infiltration speed were evaluated like physical indices of quality soils. The electric conductivity, pH, CaCO3 (%), organic matter (%) phosphorus (ppm), potassium (ppm), cation exchange capacity and exchangeable cations (Ca, Mg, Na y K), were evaluated like chemical indices ...
