Resumo: | Although recognized, the effects of lime and gypsum applications over soil organic matter dynamics is still scarcely studied. This research was developed based in the hypothesis the lime and gypsum applications create a favorable environment for biological activity, leading to increase of carbon sequestration and crop productivity. In this way, the objectives of this study were: a) to evaluate the impact of lime and gypsum applications in the soil biological quality, soil organic carbon (SOC) stocks and crop productivity in a long-term no-till system; and b) to evaluate through a laboratory incubation experiment the effects of lime and gypsum in the SOC stocks, Ca and Mg content and soil basal respiration. The field experiment was stablished in 1998 on clay Oxisol (Typic Hapludox), in Ponta Grossa – PR Brazil in a split-plot completely randomized block design. The main plots were comprised in three liming treatments: a) Control, with no lime applications, b) Incorporated lime (IL) at the rate of 4,5 Mg ha-1 and c) Surface-applied lime (SL) at the rate of 4.5 Mg ha-1 divided in three annual applications of 1,5 Mg ha-1 from the experiment establishment. The subplots were comprised by gypsum applied on soil surface at four rates: 0, 3, 6 and 9 Mg ha-1. The soil samples were collected in 2013, fifteen years after the experiment establishment. A laboratory incubation experiment was also carried out to evaluate the effects of both practices. We collected undisturbed samples in 5x5 cm steel rings, which were maintained under 28ºC in 50% of water maximum retention. The experiment design was completely randomized plots with 2x4 factorial design. The treatments assessed were: a) application or not of 4.5 Mg ha-1 of lime; and b) gypsum rates of 0, 3, 6, and 9 Mg ha-1. Over the ring surface, we added corn and soybean residues in order to simulate no-till conditions. In the field experiment, liming provided increase of soil biological activity, SOC stocks, crop productivity, biomass-C input and soil fertility. The C-biomass input and Ca content contributed significantly for increases in SOC stocks. The soil biological activity (measured by enzyme activities) was positively influenced mainly by the labile SOC fractions. Gypsum application positively contributed to increases in SOC labile fractions and arylsulfatase activity. In the incubation experiment, the lime application significantly increased the soil basal respiration, labile SOC stocks and Ca and Mg contents. The gypsum applications significantly increased the labile SOC stocks and Ca content. We observed significant contributions of soil basal respiration and Ca content in the SOC stocks increase. We conclude the lime and gypsum consist in important strategies to promote increases in SOC stocks, governed mainly by the role of Ca as a SOC biding agent and the C-biomass input; and that the use of undisturbed samples were an efficient strategy to assess the effects of lime and gypsum in no-till system. |

LIME AND GYPSUM APPLICATIONS AS STRATEGIES TO INCREASE CARBON SEQUESTRATION IN NO-TILL SYSTEM. 2016. 76 f. Dissertação (Mestrado em Agricultura) - UNIVERSIDADE ESTADUAL DE PONTA GROSSA, Ponta Grossa, 2016.http://tede2.uepg.br/jspui/handle/prefix/2279Although recognized, the effects of lime and gypsum applications over soil organic matter dynamics is still scarcely studied.

Este trabalho foi desenvolvido baseando-se na hipótese de que as aplicações de calcário e gesso criam condições favoráveis para o aumento da atividade biológica do solo conduzindo a um incremento do sequestro de carbono e produtividade das culturas. Dessa forma, o objetivo desse trabalho foi: a) avaliar o impacto da calagem e gessagem na atividade biológica do solo, estoques de C e produtividade agronômica em uma área de plantio direto de 15 anos; e b) Avaliar através de um estudo de incubação em laboratório utilizando amostras indeformadas de solo simulando condições de plantio direto, os efeitos da adição de calcário e gesso no solo sobre os estoques de C, conteúdo de Ca e Mg e respiração basal do solo. O experimento a campo foi implantado em 1998 em um Latossolo vermelho argiloso em Ponta Grossa – PR. O delineamento experimental foi em blocos inteiros aleatorizados com parcela subdividida. Os tratamentos implementados nas parcelas foram: a) controle, sem calcário; b) calcário aplicado de forma incorporada (C-inc) na dose de 4,5 Mg ha-1; e c) calcário aplicado em superfície (C-sup) na dose de 4,5 Mg ha-1, dividido em três aplicações anuais de 1.5 Mg ha-1 a partir da instalação do experimento. Os tratamentos que compuseram as subparcelas foram quatro doses de gesso: 0, 3, 6 e 9 Mg ha-1. As amostras de solo foram coletadas em 2013, quinze anos após a implantação do experimento. Um experimento realizado em laboratório com amostras incubadas também foi realizado para estudar os efeitos das práticas. Foram coletadas amostras indeformadas em anéis cilíndricos 5 x 5 cm, mantidas a 28ºC a 50% da capacidade máxima de retenção de água. O delineamento experimental foi inteiramente aleatorizado com fatorial 2 x 4. Os tratamentos foram: a) aplicação ou não de 4,5 Mg ha-1 de calcário em superfície; e b) aplicações superficiais de gesso nas doses de 0, 3, 6 e 9 Mg ha-1. Na superfície do anel foi adicionado resíduos de palha de milho e de soja em períodos distintos para simular uma condição de plantio direto. No experimento a campo, a calagem proporcionou aumento da atividade biológica do solo, estoques de C, produtividade agronômica, aporte de C via resíduos culturais e fertilidade do solo. O aporte de C via resíduos culturais e o conteúdo de Ca+2 do solo contribuíram positivamente para o aumento dos estoques de C. A atividade biológica (medida através da atividade enzimática) foi positivamente influenciada principalmente pela atuação das frações mais lábeis do C. O gesso contribuiu positivamente para o aumento das frações mais lábeis do C e também para a atividade de arilsufatase. No experimento de incubação, a aplicação de calcário aumentou significativamente a respiração basal do solo, estoques de C e concentrações de Ca e Mg. A gessagem aumentou significativamente as frações mais lábeis do C e o conteúdo de Ca. Foram observadas influências significativas do conteúdo de Ca e da respiração basal no aumento dos estoques de C do solo. Conclui-se que a calagem e a gessagem consistem em importantes estratégias para proporcionar aumento dos estoques de C do solo governado principalmente pela atuação do Ca como ligante da matéria orgânica e pelo aporte de C via resíduos culturais e que a utilização de amostras indeformadas com aporte de resíduos em superfície consiste em uma eficiente estratégia para avaliar o efeito da aplicação de calcário e gesso em plantio direto.Made available in DSpace on 2017-07-25T19:30:54Z (GMT).
