Chromatography of Pfeiffer in the evaluation of the residual effect in the soil of fertilization with vegetal ashes in experimental agricultural system

Abstract

The development of soil quality study technology such as Pfeiffer's Chromatography becomes very useful for agroecosystems managed according to agroecological principles, because it is easy to understand, low cost and address aspects related to the movement of soil life . The objective of the proposal was to evaluate the use of soil Chromatography of Pfeiffer as an indicator of the residual effect of a fertilization with ashes. The work was carried out in the municipality of Solânea-PB, in an experimental subsystem with Noni (Morinda Citrifolia) planting,located in the agricultural sector located in the first floor of the Center for Human, Social and Agrarian Sciences, Federal University of Paraíba (UFPB. Five samples composed of the respective treatments corresponding to the fertilization with plant ashes, from 0 to 15 cm were collected in the field and taken to the Agroecology Laboratory (ASDA) to perform the Chromatography practice.
