Mejoradores orgánicos en la rehabilitación de un suelo salino de General Cepeda, Coah. México

Abstract

For the present investigation were collected soil samples of the ranch “El Potrero” municipality of General Cepeda Coahuila. These were put on on handles (soil columns).The fundamental objective was to determine the two efficiency organic improves (Algaenzims and Humik-900) on salinity of the soil, as technical auxiliary of rehabilitation.The dose utilised were 6,12 and 18 lt/ha of Algaenzims and 8,16 and 24 kg/ka for Humik-900 a fertilization dose (90-90-0) and an absolute witness, what provided an eigth total treat ments, in 16 

handles, these were sown with hay rye grass perennial and were watered with water of the property. The used experimental design was handle for their analysis of salinity, with monthly courts of the hay before each application of the improves, were analyzed the samples of plant fabric in their concentration of cations and their contained of phosphorus for power to interrelate them with the method of isothermal of adsorcion in filtered of soil columns. The treatments one (6 lt/ha) of Algaenzims and six (24 kg/ha) of Humik-900 presented effect the best on salinity of the soil. The application of the organic improves Algaenzims (estract of marine algae) and Humik-900 (bioactivador Humic) tend to re duce salinity of the soil depending on the employed dose and the quality on used water.
