Summary: | ABSTRACT Golden mussel is an invasive species in South America that causes environmental and economic damage due to the formation of large colonies without natural predators. This study aimed to test the agricultural use of golden mussel shell as a limestone substitute, as the shell is rich in calcium carbonate. The experiment was carried out in pots, with eight treatments (sandy soil; clay soil; sandy soil + 1.0 Mg ha−1 of limestone; clay soil + 1.0 Mg ha−1 of limestone; sandy soil + 1.0 Mg ha−1 of fresh shell; clay soil + 1.0 Mg ha−1 of fresh shell; sandy soil + 1.0 Mg ha−1 of calcined shell; clay soil + 1.0 Mg ha−1 of calcined shell), in addition to the application of the following fresh and calcined shell doses: 0, 1.0, 1.5 and 2.0 Mg ha−1. Rice was cultivated in all treatments, and the soil fertility and rice shoot and root dry masses were evaluated. The shell provided good chemical conditions to the soils and raised their pH and phosphorus and calcium contents. The agricultural use of golden mussel shell showed to be efficient for soil correction and can be considered an alternative to limestone.
RESUMO O mexilhão-dourado é uma espécie invasora na América do Sul que causa prejuízos ambientais e econômicos, devido à formação de grandes colônias sem predadores naturais. Objetivou-se testar o uso agrícola de carapaça de mexilhão-dourado como substituto ao calcário, já que é rica em carbonato de cálcio. O experimento foi conduzido em vasos, com oito tratamentos (solo arenoso; solo argiloso; solo arenoso + 1,0 Mg ha−1 de calcário; solo argiloso + 1,0 Mg ha−1 de calcário; solo arenoso + 1,0 Mg ha−1 de carapaça in natura; solo argiloso + 1,0 Mg ha−1 de carapaça in natura; solo arenoso + 1,0 Mg ha−1 de carapaça calcinada; solo argiloso + 1,0 Mg ha−1 de carapaça calcinada), além da aplicação das seguintes doses de carapaça in natura e calcinada: 0; 1,0; 1,5; e 2,0 Mg ha−1. Cultivou-se arroz em todos os tratamentos e foram avaliadas a fertilidade do solo e a massa seca da parte aérea e das raízes do arroz. A carapaça proporcionou boas condições químicas aos solos, elevou o seu pH e os teores de fósforo e cálcio. A utilização agrícola da carapaça de mexilhão-dourado foi eficiente para a correção do solo e pode ser considerada uma alternativa ao calcário. |
