“…Removal efficiency (%) of Fe (II) was determined by: 8 (2) where: Q e is the quantity of metal uptake from solution by mass of adsorbent (mg g -1 ); C i and C e are the initial and equilibrium metal concentration (mg L -1 ), respectively; V t is the volume of solution in mL and M c is the dry weight of the adsorbent added (g).…”

“…Nowadays some resources are being applied such as biomass used in extraction of chitin and chitosan, in the industry of food and cosmetic, source of calcium in medicaments, soil additive, in promotion of plant growth, raw material in civil construction and as adsorbent of water pollution, as cobalt, copper, nickel, and others. [1][2][3][4][5][6] In Brazil, the crab species most abundant is Ucides cordatus, commonly known as Uçá crab. The crab shell is a very resistant material in which calcium carbonate is the main constituent and chitin associated to protein and mineral salts.…”

Recebido em 13/5/10; aceito em 12/1/11; publicado na web em 29/3/11In this study Ucides cordatus crab shells were utilized as Fe (II) sorbent as material of low cost and simple preparation. Values of pH of standard solution, biosorbent mass, particles size, contact time (t c ) and initial concentration of the standard solution were optimized. The best conditions were pH = 2.00, t c = 840 min and M c = 0.25 g. The kinetic pseudo first-order model displayed the best description of the adsorption process and the equilibrium study showed that the Langmuir model better describes the adsorption of the Fe (II). There is great affinity between the Fe (II) and the biosorbent.

“…Segundo Benchimol et al (2006), a adição da casca de caranguejo ao solo proporciona acréscimo na taxa fotossintética e na disponibilidade de N em plantas de pimenteira-do-reino, o que corrobora com um aumento de biomassa na parte aérea dessas plantas. Este aumento da taxa fotossintética com o uso de casca de caranguejo (Benchimol et al 2006), pode ter contribuído para o aumento nos teores dos compostos orgânicos estudados no presente trabalho.…”

“…Alguns trabalhos registram a importância da casca de caranguejo como excelente aditivo para reduzir a incidência de fusariose e para promover o crescimento de plantas (Benchimol et al, 2006). No entanto, os estudos relacionados com os efeitos da aplicação desses resíduos na salinização, no crescimento e em respostas bioquímicas das plantas, são escassos.…”

RESUMOOs resíduos de caranguejo apresentam potencial como adubo orgânico. Buscou-se neste trabalho, avaliar os efeitos da aplicação de resíduo de caranguejo Uçá na salinização do solo, no crescimento e nos teores de clorofila e solutos orgânicos e inorgânicos de plantas de melão. O experimento foi conduzido em casa de vegetação no período de maio a junho de 2010. Utilizaram-se oito tratamentos correspondendo às percentagens de 0, 1, 3, 5, 10, 20 e 30% de resíduo de caranguejo e um tratamento contendo adubação mineral (solução de Hoagland), todos com seis repetições. Trinta dias após o plantio foram avaliados em extrato solo : água (1:1) o pH, a condutividade elétrica (CE) e os teores de Na + e K + . Nas plantas foram avaliados a produção de massa seca da parte aérea, área foliar, massa seca da raiz e os teores foliares de clorofila e de solutos orgânicos e inorgânicos. O incremento nas concentrações de resíduos de caranguejo aumentou significativamente os valores de pH, CE, Na + e K + do solo. Foram observadas tendências quadráticas para as variáveis de crescimento e os teores de clorofila na planta. O aumento na CE e no teor de Na + contribuiu para reduzir o crescimento das plantas nos níveis mais elevados de resíduos de caranguejo. Palavras-chave: adubação, Ucides cordatus, Cucumis meloEffects of crab residue in soil salinization and development of melon ABSTRACT The residue of crab show potencial as organic fertilizer. This study evaluated the effect of applying concentrations of residue of crab Uçá in sanilization of soil, on growth, chlorophyll and organic and inorganic solutes in melon. This experiment was conducted under greenhouse conditions from May to June in 2010. Eight treatments were used corresponding to percentage of 0, 1, 3, 5, 10, 20 and 30% crab residue and a treatment containing mineral fertilizers (Hoagland solution), each with six replications. Thirty days after sowing in the soil : water (1:1) extract: pH, electrical conductivity (EC), and K + and Na + were evaluated. In plants dry mass of shoot, leaf area, root dry mass and leaf contents of chlorophyll and organic and inorganic solutes were evaluated. The increase in concentrations of crab residue significantly increases the pH, EC Na + and K + in the soil. Quadratic trends were observed for growth parameters and chlorophyll contents in the plants. The increase in the EC and the levels of Na + contributed to reduce plants growth in the higher levels of crab residue.

Production of black pepper clonal cuttings in commercial substrate with controlled-release fertilizerThe diseases caused by soil pathogens have brought severe losses to black pepper because of plant premature death. Thus, the objective of this work was to evaluate the production of black pepper (Piper nigrum) clonal cuttings in commercial substrate fertilized with five doses of controlled-release fertilizer. It was evaluated three genotypes 'Guajarina', 'Iaçará' and 'Cingapura', cultivated in plastic bags filled up with commercial substrate composed by pinus bark and vermiculite (without soil) fertilized with five doses of controlled-release fertilizer of the formula NPK 15-09-12: 0.0, 2.5, 5.0, 7.5 and 10 kg m . At 120 days after transplanting, the results showed growth differences among genotypes for all parameters, except plant height. The controlled-release fertilizer doses interfered on plants growth, but the interaction genotype x doses was observed only for leaf number, root dry matter and total dry matter. The highest values for total dry matter were recorded for cv. Guajarina, while cv. Cingapura showed the lowest value. The highest values for total dry matter of black pepper cuttings were obtained with the doses 4.4 kg m -3 for 'Guajarina'; 6.4 kg m -3for 'Iaçará' and 5.3 kg m -3 for 'Cingapura'.
