The liquid biofertilizers have been used with relative success in the recovery of banana planta- tions that have low productivity, after long time cultivation. However, there is little information available relat- ed to cultural practices that aim to increase the life of bananeiral. The objective of the present study was to compare areas degraded plantations that have received the application of biofertilizer for a period of two and five years and the area where the culture did not receive this type of application. The study was conducted in year of 2011 in the municipality of Chapada do Apodi Quixeré - CE. It was evaluated the effects of time of ap- plication on soil chemical attribute, biometric measurements of the plant, dry mass production, extraction and export of N, P and K, and the contribution of plant biomass. The experimental design was completely random- ized with three replications. The biofertilizer increased the content of organic matter, exchangeable Ca and K in all soil depths. The levels of disposable P and exchangeable Mg were higher only in the surface layer. The bio- fertilizer contributed to the increase of pH, the CE and Na soil. Plants that received application of the product were higher, with greater weight and number of leaves. The area received more application time showed higher productivity, accumulated 20% more dry mass, extracted more N, P and K soil, more nutrients exported through harvesting and landed larger amount of plant biomass.
