Abstract

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.
