Resumo: | Changes in land use cause a mosaic of areas in the landscape with different uses and land cover. This condition compromises the nutrients in the soil, being relevant for food production, mainly because they can compromise losses and reduction of phosphorus (P) stocks in the system. Therefore, this work aimed to determine the phosphorus concentrations in the depths of the main classes in different uses and soil cover in the Agreste region of Pernambuco. Samples from the soil bank collected by the group of researchers from the Department of Nuclear Energy of the Federal University of Pernambuco, carried out between 2011 and 2015 were used for these studies. Thus, extractable and total phosphorus concentrations were determined in (192 samples) in 04 classes (Algisol, Litholic Neosol, Regolithic Neosol and Planosol) of soil, 04 land uses (Open Caatinga, Dense Caatinga, Agriculture and Pasture) in 04 layers (0-10, 10-20, 20-30 and 30-40 cm). To determine the extractable P, the Mehlich 1 and colorimetric reading were used. The total phosphorus was determined by sulfuric digestion to obtain the extracts and also being determined by colorimetry. The results of the concentrations found for both extractable and total P were higher for the Argisol and Planosol classes. It was observed that there were reductions in extractable P concentrations between the soil layers as the soil profile deepened. The superficial layers, between 0-20 cm, generally presented the highest concentrations of extractable and total phosphorus in agriculture. Among the four soil classes studied, the highest average values of extractable and total P stocks occurred in Litholic Neosols and Planosols, mainly due to agricultural use. P is an element of great importance for plant development. P deficiency has been a limiting factor to agricultural productivity and, especially in the Agreste region of Pernambuco, where the main soil classes under natural cover have low levels of available and total P. Finally, the sustainable management of natural ecosystems and knowledge of the dynamics of P in the soil are extremely important to increase its bioavailability in tropical soils. |

Esta condição compromete os nutrientes no solo, sendo relevantes para produção de alimentos, principalmente, porque podem comprometer perdas e redução dos estoques de fósforo (P) no sistema. Diante disso, o trabalho teve como objetivo determinar as concentrações de fósforo nas profundidades das principais classes em diferentes usos e coberturas dos solos na região do Agreste pernambucano. Sendo utilizadas para estes estudos, amostras do banco de solos coletadas pelo grupo de pesquisadores do Departamento de Energia Nuclear da Universidade Federal de Pernambuco realizada entre 2011 e 2015. Com isso, foram determinadas as concentrações de fosforo extraível e total em (192 amostras) em 04 classes (Argissolo, Neossolo litólico, Neossolo Regolítico e Planossolo) de solo, 04 usos da terra (Caatinga Aberta, Caatinga Densa, Agricultura e Pastagem) em 04 camadas (0-10, 10-20, 20-30 e 30-40 cm). Para determinação do P extraível foi utilizado o Mehlich 1 e leitura por colorimetria. O fósforo total foi determinado por digestão sulfúrica para obtenção dos extratos e também sendo determinado por colorimetria. Os resultados das concentrações encontradas tanto de P extraível quanto do total foram mais altas para a classe do Argissolo e Planossolo. Observou-se que ocorreram reduções das concentrações de P extraível entre as camadas do solo à medida que foi se aprofundando no perfil do solo. As camadas superficiais, entre 0-20 cm, apresentaram de maneira geral as maiores concentrações de fósforo extraível e total na agricultura. Dentre as quatro classes de solo estudadas, os maiores valores médios de estoques de P extraível e total ocorreram nos Neossolos litólicos e Planossolos, principalmente pelo uso na agricultura. O P é um elemento de grande importância para o desenvolvimento das plantas. A deficiência de P tem sido um fator limitante à produtividade agrícola e, sobretudo nas regiões do Agreste pernambucano, onde as principais classes de solos sob coberturas naturais apresentam baixos teores de P disponível e total. Por fim, o manejo sustentável dos ecossistemas naturais e o conhecimento da dinâmica do P no solo são de extrema importância para o aumento da sua biodisponibilidade em solos tropicais.Submitted by (ana.araujo@ufrpe.br) on 2023-06-28T16:33:41Z No. of bitstreams: 1 Igor Revelles Gomes Luna.pdf: 1023953 bytes, checksum: 0a50f81e492cb7316521ef97d1182d8c (MD5)Made available in DSpace on 2023-06-28T16:33:41Z (GMT).
