Elementos esenciales (N, P, K), pH y CE del horizonte C en el suelo del campus La María, cantón Mocache

In this research, 20 soil samples were extracted from different cultivated sites, according to their georeferencing and use on an agricultural or livestock basis, the variables evaluated are the content of Nitrogen (N), Potassium (P), Phosphorus (K), pH and conductivity (CE) on horizon C of the "La María" Campus of the State Technical University of Quevedo, applying a Completely Random Design (DCA) with 3 treatments and three repetitions. The statistical differences were shown with a Test of Tukey (P- 0.05) error. The results were analyzed according to the agricultural use area of the established crop, in sites cultivated with African palm, (T3) Savoygrass (T20) presented percentage values of 8,55 to 19,92 ppm NH4+ , in addition to crops in Savoy grass (T7) citrus (T18) obtained P values of 2,12 to 8,46 ppm, while banana cultivation (T1) and National Cocoa in Agronomy (T12) express K values of 58,50 to 507,00 ppm, in addition to Savoy grass (T17) banana (T1) sites contained in pH H2O, showed values from 5,67 to 7,57 strong acid to moderately alkaline with an average of x =6.93 neutral, following in pH CaCL the cultivation of soursop (T10) maize (T2) achieved values from 6.93 to 5.77 neutral and moderately acidic with an average in x =6.26 slightly acidic, the EC continuing the culture the culture Bananas (T8) Bananas in Agronomy (T13) achieved results of 26,37 to 71,87 s/cm with averages of x = 45.65 µs/cm. Keywords: soil, horizon, crops, georeferencing, samples, variables, macro elements.
