The constant increasing of eucalyptus forest areas in Brazil requires an accurate monitoring of water erosion. The present study aimed to evaluate soil, nutrients and organic carbon losses occasioned by water erosion in eucalyptus planted forests (EPF) at different development stages (2, 3 and 7 years old). Soil erosion sediments were measured and sampled from standard erosion plots installed on Red Argisol-RA (Ultisol) and Haplic Cambisol-HC (Inceptisol). Soil loss decreased as the age of plants increased; at the beginning of plant development, the canopy barely covered the soil surface, exposing the soil to higher erosion at young EPF plantations. Furrow planting system was used in the Red Argisol area and caused higher soil losses (1.1 to 6.2 Mg ha-1 year-1) as compared to pit planting system that was used in the Cambisol area (1.1 Mg ha-1 year-1). It is known that Cambisol is less resistant to erosion than Argisol. However, using pit system in this EPF, resulted in lower erosion and, therefore, nutrients and carbon losses than the traditional furrow system used in Argisol. Concerning the soil loss, this work points to the need of improving soil conservation practices to prevent soil erosion at the earlier stages of eucalyptus plantation. The amount of calcium and potassium were higher than magnesium in the soil sediment.The relatively high amount of carbon found in the erosion sediments raises additional concerns about the environmental sustainability and deserves future research.

The availability of single assai palm (Euterpe precatoria) seedlings with good quality is a fundamental requirement to expand the cultivation of the species. This study aimed to assess the use of fruit agro-industry residues as substrate for producing single assai seedlings. The experiment was carried out under nursery conditions, in a completely randomized design, with four replications and eight plants per plot. Fifteen treatments were evaluated: a commercial substrate, four dry and crushed agro-industrial residues (Brazil nut shell, acerola pit, assai pit and cupuassu peel) and ten combinations of these materials in the proportion of 1:1. The following variables were also measured: shoot height; stem diameter; number of leaves; shoot, root and total dry mass; and Dickson Quality Index score. The substrate formulated with Brazil nut shell + acerola pit stood out for promoting a higher growth and dry biomass, resulting in seedlings with a better quality. The pure assai pit residue was not efficient for producing seedlings, but it showed a good potential when mixed in equal proportion with other materials (e.g. Brazil nut shell and cupuassu peel). A disponibilidade de mudas de açaizeiro solteiro (Euterpe precatoria) de boa qualidade é requisito fundamental para a expansão do cultivo da espécie. Objetivou-se avaliar a utilização de resíduos de agroindústrias frutíferas como substrato para a produção de mudas de açaizeiro solteiro. O experimento foi conduzido em condições de viveiro, em delineamento inteiramente casualizado, com quatro repetições e oito plantas por parcela. Quinze tratamentos foram avaliados: um substrato comercial, quatro resíduos agroindustriais secos e triturados (casca de amêndoa de castanha-do-Brasil, caroço de acerola, caroço de açaí e casca de cupuaçu) e dez combinações desses materiais na proporção 1:1. Também foram mensuradas as seguintes variáveis: altura da parte aérea; diâmetro do colo; número de folhas; massa seca da parte aérea, raiz e total; e Índice de Qualidade de Dickson. O substrato formulado com casca de amêndoa de castanha-do-Brasil + caroço de acerola destacou-se por promover maior crescimento e biomassa seca, resultando em mudas de melhor qualidade. O resíduo de caroço de açaí puro não foi eficiente para a produção de mudas, mas apresentou bom potencial quando em mistura de igual proporção com outros materiais (p. ex. casca de amêndoa de castanha-do-Brasil e casca de cupuaçu).
