“…The soil samples were dried in a forced air laboratory oven at 45 o C until constant weight, ground, passed through a sieve with a 2 mm screen and analyzed for available P (experiment 1) and exchangeable K (experiment 2), both extracted by the Mehlich 1 method. The leaves were dried, ground and prepared for analysis of P content (experiment 1) and of K content (experiment 2) (MELO et al, 2012).…”

“…In the same way, but in a readier manner, K migration occurs, as long as the quantity added is greater than that used by the crops, because its adsorption to the functional groups of inorganic and organic reactive particles takes place with low binding energy, facilitating its migration in the soil profile (KAMINSKI et al, 2007). With the accumulation of available P and exchangeable K in soil surface layers and even in deeper layers, it is expected that part of these nutrients draws near the outside surface of the roots, especially through diffusion and, if taken up, contents of the nutrients will increase within the plant, and this may be diagnosed by the total content in the whole leaves (MELO et al, 2012;CURETTI et al, 2013). Therefore, an increase may be expected in the values of yield components, such as fruit weight, which may be reflected in an increase in fruit yield per plant and per area (NEILSEN et al, 2008;DECHEN, 2009).…”

-The aim of this study was to evaluate the response to phosphorus (P) and potassium (K) fertilization and to establish the critical levels of P and K in the soil and in the plant tissue in pear trees. Two experiments were conducted in São Joaquim (SC), Brazil. In experiment 1, the plants received annually the application of increasing rates of phosphate fertilizer (0, 40, 80, 120 and 160 kg P 2 O 5 ha -1 ), while in experiment 2, increasing rates of potassium fertilizer (0, 40, 80, 120 and 160 kg K 2 O ha -1 ) were applied annually. In the two experiments, soil was collected annually from the 0-10, 10-20 and 0-20 cm layers, and the available P (experiment 1) and exchangeable K (experiment 2) content was analyzed. Whole leaves were collected annually, which were subjected to analysis of total P (experiment 1) and total K (experiment 2) content. The number and weight of the fruits per plant and fruit yield were evaluated. Application of P on the soil planted with pear trees increased the nutrient content in the soil and, in most crop seasons, in the whole leaf, but it did not affect the yield components and fruit yield. The application of K on the soil with pear trees increased the nutrient content in the soil and, in most of the crop seasons, in the whole leaf, but the potassium content in the whole leaf decreased in the crop season with greater fruit yield. The yield components and fruit yield were not affected by K fertilization. Index terms: Pyrus communis L., sufficiency level, phosphate fertilization, potassium fertilization, yield. RESPOSTA DA PEREIRA À APLICAÇÃO DE FÓSFORO E POTÁSSIORESUMO -O trabalho objetivou avaliar a resposta à adubação com fósforo (P) e potássio (K) e estabelecer o nível crítico no solo e no tecido de P e K em pereira. Dois experimentos foram conduzidos em São Joaquim (SC). No experimento 1 as plantas receberam anualmente a aplicação de doses crescentes de fertilizante fosfatado (0; 40; 80; 120 e 160 kg de P 2 O 5 ha -1 ), enquanto no experimento 2 foram aplicadas anualmente doses crescentes de fertilizante potássico (0; 40; 80; 120 e 160 kg de K 2 O ha -1 ). Nos dois experimentos foi coletado anualmente solo nas camadas de 0-10; 10-20 e 0-20 cm, onde foi analisado o teor de P disponível (experimento 1) e K trocável (experimento 2). Anualmente foram coletadas folhas completas que foram submetidas à análise do teor total de P (experimento 1) e K (experimento 2). Avaliaram-se o número e a massa dos frutos por planta e a produção de frutos. A aplicação de P no solo cultivado com pereira incrementou o teor do nutriente no solo e, na maioria das safras, na folha completa. Porém, o incremento do teor de P disponível no solo e na folha não foi acompanhado de aumentos nos componentes de produção e na produção de frutos, impossibilitando o estabelecimento do nível crítico de P no solo e no tecido. A aplicação de K no solo aumentou o teor do nutriente no solo e, na maioria das safras, na folha completa da pereira, mas o teor de K na folha completa diminuiu na safra com maior produção d...

“…Outra parte do N derivado da mineralização pode ser volatilizada na forma de N-NH 3 (MATTOS et al, 2003). Porém, a quantidade de formas de N lixiviadas e de N-NH 3 volatilizada é dependente da composição do composto aplicado, da sua dose e de condições climáticas, como precipitações e temperatura do ar (ERHART et al, 2007).…”

RESUMO A aplicação de composto orgânico no solo pode incrementar a produção de pêssego, porém parte do N pode ser perdido por lixiviação e volatilização. O trabalho objetivou avaliar o estado nutricional das plantas, a produção de pêssego, a lixiviação de formas de N no solo e a volatilização de N-NH Palavras-chave: resíduo orgânico, N mineral, Prunus persica. ABSTRACT The application of organic compost to the soil can increase the production of peach, although part of the N may be lost by leaching and volatilization. The aim of this study was to evaluate the nutritional status, yield of peaches, leaching of N forms and volatilization of NH

“…When applied to the soil, compost may be mineralized over time by soil microorganisms in the peach orchard, which would increase the total organic C content, the microbial biomass C content, and the metabolic activity of the microorganisms (Adani, Genevini, Ricca, Tambone, & Montoneri, 2007;Baldi et al, 2010a). The application of compost may also increase the soil porosity, which would reduce the soil density (Melo, Brunetto, Basso, & Heinzen, 2012) and increase the availability of nutrients, such as N, P, K, Acta Scientiarum.

ABSTRACT. The purpose of this study was to evaluate the nutritional state, yield and composition of peaches on peach trees subjected to the application of organic compost to the soil. This experiment was . Avaliou-se o teor de nutrientes totais nas folhas, componentes de produção, produção por planta e hectare e a composição dos frutos em 2008 e 2009, logo depois da colheita e 30 dias após armazenamento. A aplicação de composto orgânico no solo, aumenta os valores de componentes de produção e a produção de pêssego por planta e hectare, nas duas maiores quantidades de composto fornecidas, o que economicamente indica a melhor dose de 72 L de composto por planta -1 . A adição de composto orgânico na superfície do solo não afeta o estado nutricional e pouco afeta a composição dos pêssegos após a colheita e depois de 30 dias do armazenamento.Palavras-chave: nutrição mineral, resíduos orgânicos, Prunus persica.
