Most of the soils for agriculture differ in their chemical, physical and biological properties the participation of each one of these determines the natural fertility that has the soil for the establishment of crops. The importance of understanding the electrochemical properties of soils as fertility parameters is currently unknown, where the determination of variables such as cation exchange capacity (CEC) and Point Zero (PCC) will promote the proper management and calibration of fertility plans. One of the key parameters to identify soils variable load or permanent load is the determination of the PCC, identified as the pH value in which both positive and negative charges are equal; therefore if natural state soil has a pH above the PCC w...
