Caracterización de materiales con uso potencial como sustratos en sistemas de cultivo sin suelo

Abstract: A pesar de su baja capacidad de retención de agua y de cationes, la cascarilla de arroz es el sustrato más utilizado en cultivos sin suelo (CSS) en Colombia; sin embargo, su disponibilidad ha venido disminuyendo debido a la diversificación de su uso. Con el fin de proponer materiales alternativos, se realizó la caracterización de las propiedades químicas y físicas más relevantes en once sustratos orgánicos y siete minerales, para conocer su viabilidad de uso, inocuidad y estabilidad. Los resultados indican que… Show more

“…10,15,[20][21][22] The EC value is the minimum with the value of 21.9 μs/cm for TT1 and it is the maximum for TT8 with the value of 950 μs/cm (see Figure 1c). The EC values are among 20 and 1600 μs/cm for perlite, 15,[20][21][22] 70 and 100 μs/cm for Vermiculite, 10,15 40 μs/cm for rock wool, 15 70 and 700 μs/cm for pumice, 10,23 100 μs/cm for zeolite. 10 In this study, the ECs of perlite and pumice are among the values calculated in the scientific literature.…”
