Coconut Research and Applications

The adoption of cover crops in commercial plantations has been shown to be an alternative to promote greater soil protection, enhancement in its structure and aggregation, optimization of accumulation and nutrient cycling to obtain greater production of biomass and higher nitrogen fixation.To determine the accumulation of micronutrients of Pueraria phaseoloides L., according to age, established as a soil cover in industrial oil palm crops, an experiment was carried out at Companhia Agroindustrial (CRAI) in the municipality of Tailândia, State of Pará, in an Oxisol.The experimental design was a randomized block with four replicates.The results allow to conclude that the accumulation of nutrients, except for Mn and Cu in the live Pueraria phaseoloides L. plant cover reduced over the years and those of B, Mn, Zn, and Cu were greater in the dead Pueraria phaseoloides L. plant cover and for Cl it was in the live Pueraria phaseoloides L. plant cover.The decreasing order of total micronutrient extraction was the following: Cl> Mn> B> Zn> Cu.
