This book was released on 2009 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: O uso de dejetos de suínos na cultura do milho em regiões produtoras de suínos é uma prática cada vez mais freqüente no Sul do Brasil, cujos efeitos no solo são ainda pouco avaliados pela pesquisa. Diante disso, o objetivo desse trabalho foi o de avaliar os atributos físicos e químicos do solo comparando a utilização de diferentes fontes de nutrientes e o impacto do uso de dejetos suínos na lixiviação de NO3- e metais pesados. O experimento foi desenvolvido durante o período 2007/2008, em área experimental no município de Braço do Norte, SC, que vem sendo monitorada quanto a aplicação dos dejetos, desde 2002. O delineamento empregado foi o de blocos ao acaso com sete tratamentos e três repetições. Os tratamentos foram constituídos por cama sobreposta de suínos (CS), dejeto líquido de suínos (DL) e adubação química (AQ), todos com dois níveis de adubação uma e duas vezes a recomendação de N da cultura do milho e pela testemunha (T) sem adubação. Foram realizadas avaliações na camada de 0-5 cm para os atributos físicos e os químicos foram avaliados em quatro profundidades nas camadas de 0-15, 15-30, 30-45 e 45-60 cm em seis datas durante o ciclo do milho. As adubações orgânicas promoveram alterações na maioria dos atributos analisados com pequenas diferenças entre si quanto aos atributos físicos após cinco anos de aplicação no solo. As maiores diferenças foram observadas nos atributos químicos, com os maiores valores observados na camada superficial do solo, mas diminuindo em profundidade, exceto para o Al. O P e K apresentaram valores muito altos no solo inclusive em profundidade. Os resultados indicam a ocorrência de lixiviação de NO3- e concentração de Zn, Cu e Mn no solo, porém ainda não em níveis críticos no solo.
Book Synopsis Dinâmica da matéria orgânica do solo sob os sistemas de plantio direto e convencional em diferentes rotações de cultura através de fracionamento químico by : L. da C. RIOS
Download or read book Dinâmica da matéria orgânica do solo sob os sistemas de plantio direto e convencional em diferentes rotações de cultura através de fracionamento químico written by L. da C. RIOS and published by . This book was released on 2003 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: O uso adequado do solo tem exigido uma melhor compreensão dos processos físicos, químicos e biológicos que dinamizam o seu comportamento. Os conhecimentos desses processos são enormes em condições de manejo intensivo do solo, através de sistemas convencionais alicerçados no usos de arados e grades monocultoras. Além de exigir o uso cada vez maior de insumos, esses sistemas tem sidos considerados os responsáveis pela intensa degradação do solo e redução da capacidades produtivas das culturas e pastagem. A procura e adoção de sistemas alternativos de manejo do solo tyem aumentado muito nos últimos anos. Neste sentido, os sistemas baseados no plantio direto, associados com práticas agroecológicas, como rotação de culturas, a adubação verde com leguminosas e gramíneas, entre outros, tem se mostrados como possível alternativa concreta. O presente estudo foi conduzido com finalidade de quantificar o efeito do manejo na matéria orgânica e seus componentes - substâncias húmicas - de um latossolo vermelho-escuro distrófico, em diferentes sistema de cultivo: Plantio direto (pd) e Plantio convencional (pc), com diferentes rotações de cultura, em campo experimental da Embrapa Trigo (cnpt), localizada no município de Passo fundo - RS. Foram realizados as caracterizações físicas, químicas dos solos além da extração e fracionamento químico das substâncias húmicas, quantificação de C e N totais e do estoque de carbono para todas as amostras coletadas nos perfis do experimento e no perfil de floresta. Os resultados mostram que os maiores teores de carbono total (ct) do solo foram encontrados no solo sob mata, enquanto que em solos cultivados a atividade agrícola a uma diminuição da matéria orgânica, sendo que a maior redução ocorreu em solo sob sistema de Plantio convencional (pc). O fracionamento da matéria orgânica do solo mostrou que o húmus dos solos estudados se caracteriza, principalmente, pela presença significativa de matéria orgânica não humificada, baixa proporção de ácidos fúlvico livres e ácidos húmicos, domínio da fração ácido fúlvico ligado (complexado) e na fração húmica na constituição do húmos. O estoque de carbono o sistema de plantio direto convencional apenas no horizonte Ap dos três tratamento estudados, possivelmente devido ao aumento da biomassa de plantio direto. Nos horizontes AB e BA os valores do estoque do carbono se mostraram quase que constantes em todos os tratamentos estudados.

Book Synopsis Proximal Soil Sensing by : Raphael A. Viscarra Rossel
Download or read book Proximal Soil Sensing written by Raphael A. Viscarra Rossel and published by Springer Science & Business Media. This book was released on 2010-07-25 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on developments in Proximal Soil Sensing (PSS) and high resolution digital soil mapping. PSS has become a multidisciplinary area of study that aims to develop field-based techniques for collecting information on the soil from close by, or within, the soil. Amongst others, PSS involves the use of optical, geophysical, electrochemical, mathematical and statistical methods. This volume, suitable for undergraduate course material and postgraduate research, brings together ideas and examples from those developing and using proximal sensors and high resolution digital soil maps for applications such as precision agriculture, soil contamination, archaeology, peri-urban design and high land-value applications, where there is a particular need for high spatial resolution information. The book in particular covers soil sensor sampling, proximal soil sensor development and use, sensor calibrations, prediction methods for large data sets, applications of proximal soil sensing, and high-resolution digital soil mapping. Key themes: soil sensor sampling – soil sensor calibrations – spatial prediction methods – reflectance spectroscopy – electromagnetic induction and electrical resistivity – radar and gamma radiometrics – multi-sensor platforms – high resolution digital soil mapping - applications Raphael A.

Book Synopsis Plant Nematology, 3rd Edition by : Roland N. Perry
Download or read book Plant Nematology, 3rd Edition written by Roland N. Perry and published by CABI. This book was released on 2024-07-12 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-parasitic nematodes are a major threat to crop production in all countries, and identification of nematodes and knowledge of their biology is of paramount importance. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and then builds on this foundation to detail nematode biology and pest management, including resistance, and biological and chemical control. This 3rd edition is updated to address advances in our knowledge of plant-parasitic nematodes, particularly concerning the molecular aspects of host-parasite relationships, including the application of genomics to nematode biology. Changes in control and management strategies are also covered. The influence of climate change on plant-parasitic nematodes is addressed in a new chapter on ecology. Primarily aimed at students (MSc and PhD), this book is also invaluable for researchers and lecturers in nematology, plant pathology and parasitology, advisory and quarantine services, and crop protection scientists.
