Resumo: | Degraded pastures reduce profitability, contribute to the increase in silting up of rivers, in addition to reducing the infiltration and storage of water in the soil, and also favor emissions of greenhouse gases. Planted forests are a viable option for reversing the process in the soil: new fast-growing forest species, such as the balsa wood (Ochroma pyramidale), are indicated as a good economic alternative and with environmental gains, by the sequestration of atmospheric carbon and for the physical recovery of degraded soil. Fertilized increases in biomass production balsa wood, anticipating the shallow cut. However, there is little research that integrates aspects of nutritional management, carbon stock in the soil and least limiting water range (LLWR). The objective of this work was to evaluate how nutritional management, with increased fertilization, alters the carbon stock in the soil and whether the physical-hydro quality of the soil improves, based on the LLWR after seven years of planting. The experiment was implemented in 2011 at the Federal Institute of Education, Science and Technology of Mato Grosso (IFMT) Guarantã do Norte Advanced Campus. The carbon stock in the soil was evaluated at the initial fertilization levels, in a randomized block design with three replications for the 0-0.30 m layer, in a Yellow Red Latosol. Additionally, it was also contracted with soil data from before the experiment was implemented, in addition to an area of native forest and degraded pasture. In undisturbed samples, in the 0-0.10 m and 0.10-0.20 m layers, it was evaluated if the physical-hydric quality improved, having the LLWR as a base and compared with the degraded pasture, after seven years of planting. It is concluded, after seven years, the proper fertilization of the balsa wood increases the carbon stock in the soil in the 0-0.30 m layer by 18%. Still, it was observed that the nutritional management of the balsa wood, with increased fertilizer dose, promotes improvement in the physical-hydric quality of the soil, restricted to the planting line. |

As florestas plantadas apresentam-se como opção viável para reversão do processo no solo: novas espécies florestais de rápido crescimento, como o pau de balsa (Ochroma pyramidale), são apontadas como boa alternativa econômica e com ganhos ambientais, pelo sequestro de carbono atmosférico e pela recuperação física do solo degradado. A adubação aumenta a produção de biomassa no pau de balsa, antecipando o corte raso. No entanto, são escassas pesquisas que integrem aspectos do manejo nutricional, estoque de carbono no solo e intervalo hídrico ótimo (IHO). O objetivo deste trabalho foi avaliar como o manejo nutricional, com aumento da adubação altera o estoque de carbono no solo e se a qualidade físico-hídrica do solo melhora, tendo o IHO por base aos sete anos de plantio. O experimento foi implantado em 2011 no IFMT Campus Avançado de Guarantã do Norte. Foi avaliado o estoque de carbono no solo nos níveis de adubação inicial, em delineamento de blocos casualizados com três repetições para a camada de 0-0,30 m, em um Latossolo Vermelho-Amarelo. Adicionalmente foi contratada também com os dados do solo de antes da implantação do experimento, além de uma área de mata nativa e de pastagem degradada. Em amostras indeformadas, nas camadas de 0-0,10 m e 0,10-0,20 m, foi avaliado se a qualidade físico-hídrica melhorou, tendo o IHO por base e comparado com a pastagem degradada, aos sete anos de plantio. Conclui- se, após sete anos, a adubação adequada do pau de balsa aumenta em 18% o estoque de carbono no solo na camada de 0-0,30 m. Ainda, observou-se que o manejo nutricional do pau de balsa, com aumento da dose de adubação, promove melhoria na qualidade físico-hídrica do solo, restrita ao sulco de plantio.Universidade Federal de Mato GrossoBrasilInstituto de Ciências Agrárias e Ambientais (ICAA) – SinopUFMT CUS - SinopPrograma de Pós-Graduação em AgronomiaZolin, Cornélio Albertohttp://lattes.cnpq.br/5614300732917044Zolin, Cornélio Alberto048.905.279-74http://lattes.cnpq.br/5614300732917044Magalhães, Ciro Augusto de Souza014.349.086-90http://lattes.cnpq.br/7758770757321541048.905.279-74Freddi, Onã da Silva301.055.828-75http://lattes.cnpq.br/9642805874485976Caravina, Sandro Marcelo2023-10-09T16:16:27Z2020-03-062023-10-09T16:16:27Z2019-12-17info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisCARAVINA, Sandro Marcelo.
