A mineração de cassiterita na mina Serra da Onça, localizada na Floresta Nacional do Jamari, Estado de Rondônia, causou profundas alterações físicas, químicas e biológicas nos solos. Em 1997, a área foi dividida em parcelas e foi dado início a um programa de recuperação, que consistiu na modelagem do terreno, construção de terraços, calagem, fertilização, plantio de leguminosas e plantio de espécies nativas. Em cada ano que se sucedeu, foram instaladas novas parcelas para serem recuperadas, às quais se aplicou o mesmo programa de recuperação, de tal modo que, no momento da amostragem, cada área recebeu uma nota de avaliação de 1 a 7 de acordo com o estádio visual de recuperação. Este trabalho teve por objetivo avaliar os atributos químicos e bioquímicos...

ABSTRACT The large production of sewage sludge (SS), especially in large urban centers, has led to the suggestion of using this waste as fertilizer in agriculture. The economic viability of this action is great and contributes to improve the environment by cycling the nutrients present in this waste, including high contents of organic matter and plant nutrients. This study evaluated the chemical and biochemical properties of Dystrophic and EutroferricLatossolos Vermelhos (Oxisols) under corn and after SS application at different rates for 16 years. The field experiment was carried out in Jaboticabal, São Paulo State, Brazil, using a randomized block design with four treatments and five replications. Treatments consisted of control - T1 (mineral...

Abstract The method used to dry plant tissue samples may modify its nutrient content, and results in incorrect diagnostic of crop nutritional status. The hypothesis was that microwave drying method does not affect the nutrient content of leaves neither the interpretation of the results, as compared to oven-drying procedure. In this study we evaluated the effect of microwave drying of eucalyptus (Corymbia Citriodora (Hook.)) and rubber trees (Hevea brasiliensis Muell. Arg.) leaves on dry matter and macronutrient content, as compared to oven drying. The study was performed in a laboratory at the Department of Soils and Fertilizers of Universidade Estadual Paulista “Julio de Mesquita Filho”, UNESP, Jaboticabal-SP-Brazil. The experiments were: one using leaf...

Several synthetic and commercial analogs of 1,4-dimethoxybenzene, a kairomone of Diabrotica speciosa, along with other compounds already shown to be attractive to other species of Diabrotica, were tested as attractant to D. speciosa. Yellow cup traps were lured with the compounds and installed in a common bean field. Assessments were conducted 24 h later. 1,4-dimethoxybenzene lured traps caught significantly more beetles than the control traps. Captures of traps lured with 1,4-dimethoxybenzene analogs did not differ from the control traps. Results showed that position and nature of the substituents on the aromatic ring played a crucial role in the activity of the natural compound. The aromatic ring was also very important to the activity of the kairomone.
