摘要

A minera??o tem promovido um grande aumento na ocorrência de áreas degradadas advindas de atividades mineradoras no Brasil. O objetivo deste trabalho foi avaliar o crescimento da candeia sob a influência da aduba??o mineral e organica quando cultivada em rejeito da minera??o de quartzito. Conduziu-se um experimento em casa de vegeta??o em delineamento experimental inteiramente casualizado com quatro repeti??es. Os tratamentos consistiram de cinco combina??es de aduba??o organica (AO) e mineral (AM) e um tratamento adicional do rejeito sem AO e AM (Controle). As combina??es foram: 0%AO/100%AM; 25%AO/75%AM; 50%AO/50%AM; 75%AO/25%AM; 100%AO/0%AM. As doses de 100% de AM e AO foram de 0,15 gde N, 0,32 gde P2O5, 0,18 g de K2O e 5 g de esterco de curral por dm3 de rejeito. A candeia respondeu positivamente à aduba??o mineral e organica com as doses recomendadas de 0,075 g N, 0,16 g P2O5 e 0,09 g K2O e 2,5 g de esterco de curral, por dm3 de rejeito da minera??o de quartzito. O acúmulo de nutrientes na espécie candeia foi na seguinte ordem na parte aérea: K > N > P > Ca > Mg >S > Mn > Fe > B > Zn > Cu.Palavras-chave: área degradada; teor adequado; estado nutricional; espécie nativa.?AbstractGrowth of Eremanthus erythropappus by mineral and organic fertilization on mining reject of quartzite. There is a large increase of degraded areas as result of mining activities in Brazil. This research aims to evaluate growth of the Eremanthus erythropappus on mining reject of quartzite, under the influence of mineral and organic fertilizer. We developed an experiment in a greenhouse, in completely randomized design with four replications. The treatments consisted of five combinations of mineral (MF) and organic (OF) fertilizer, and an additional treatment of mining reject without MF and OF (witness). The combinations were as follows: 0%OF/100%MF; 25%OF/75%MF; 50%OF/50%MF; 75%OF/25%MF; 100%OF/0% MF. Doses of 100% MF and OF were: 0,15 g of N, 0,32 g of P2O5, 0,18 g of K2O, and 5 g of bovine manure per dm3 of mining rejects. The Eremanthus erythropappus responded to mineral fertilization with recommended doses of 0,075 g N, 0,16 g P2O5 and 0,09 g K2O and 2,5 g of bovine manure per dm3 of mining reject of quartzite. The accumulation of nutrients in the species Eremanthus erythropappus on the shoot was as follows: K > N > P > Ca > Mg >S > Mn > Fe > B > Zn > Cu.Keywords: Degraded area; nutritional status; nutrients accumulation; native species.
