Book excerpt: As hortas são ambientes agrícolas resultantes da interação entre ações humanas, plantas (cultivadas e espontâneas) e o ecossistema do solo. A crença de que o solo deva ser revolvido e pulverizado é difundida em todo o mundo, tanto em hortas comerciais como nas caseiras. Mesmo nas iniciativas de olericultura orgânica esta prática é generalizada. Usando parâmetros químicos (pH, teores de fósforo disponível, potássio disponível, matéria orgânica, alumínio trocável, cálcio solúvel, magnésio solúvel, carbono orgânico, nitrogênio total), físico (densidade aparente) e biológicos (diversidade de população de fauna de invertebrados do solo, estimada através dos índices de diversidade de Shannon e de Simpson, de dominância de Simpson e de uniformidade de Pielou), analisados em conjunto com a evolução da comunidade de hortaliças cultivadas e plantas espontâneas, foram identificados efeitos no solo de uma técnica peculiar de manejo que minimiza o revolvimento, aqui denominada de canteiros elevados. O sistema de preparo dos canteiros elevados consiste no acamamento ou roçada da vegetação e colocação sobre esta de diversos materiais orgânicos. Os plantios são realizados sobre este material, após períodos variáveis de repouso. Este manejo de solo permitiu a significativa elevação da fertilidade do solo simultaneamente com cultivos contínuos de hortaliças em produção convivendo com plantas espontâneas. A densidade do solo foi uma das variáveis mais sensíveis ao manejo, provavelmente devido a sua relação com a heterogeneidade espacial do solo. Todas as variáveis químicas do solo mostraram-se sensíveis ao manejo. A estimativa de diversidade de fauna de invertebrados do solo apontou para o aparecimento de taxa de invertebrados antes ausentes, indicando a possibilidade do estabelecimento de novos nichos ecológicos. A passagem de uma colônia de formigas de correição (Eciton sp) pode ter reduzido a diversidade de fauna do solo em algumas áreas, porém sua presença é indicativa da complexidade da rede trófica estabelecida. A perspectiva co-evolucionária parece ser o enfoque mais plausível para explicar algumas variações surgidas no estudo.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: O livro Sistema de plantio direto de Hortaliças: método de transição para um novo modo de produção (SPDH) apresenta o resultado do acúmulo de duas décadas de pesquisas, desde o final dos anos 1990, pelo movimento técnico, revestido de cunho político-pedagógico, na região do Contestado, em Santa Catarina. Esse movimento, com a participação direta de educadores populares, instituições públicas federais e estaduais de pesquisa, extensão e ensino do Brasil e do exterior, refundou a base teórica da implementação técnica da pedagogia de transição de um sistema de hortaliças, tradicional e falido, para uma condição agroecológica. Essas pesquisas têm como contexto a reação popular ao vigente modelo agroquímico-industrial, visando a obtenção de saúde do solo, da atmosfera, da água, da planta, do meio ambiente em geral e dos seres humanos envolvidos, tanto na produção quanto no consumo. O SPDH tem como base a articulação entre movimento, prática e ciência, tomando como método a pesquisa-ação e o princípio freiriano da ação-reflexão-ação, envolvendo os agricultores familiares. Seus resultados permitem que as famílias camponesas participem com confiança no processo de transição agroecológica. Para servir como referência teórica e didática do SPDH, o livro está dividido em cinco seções, com 20 capítulos: eixos político-pedagógico e técnico-científico; promoção da saúde do solo; promoção da saúde da planta; preparando o ambiente para o cultivo das plantas; cultivando plantas. Cada um dos capítulos abordam as questões teóricas, técnicas e as orientações práticas, com apoio de fotos e ilustrações. O livro finaliza com a apresentação de um guia prático, um verdadeiro guia de campo, sobre os aspectos relacionados à adubação das espécies cultivadas no sistema SPDH. TRECHO DO LIVRO “O Sistema de Plantio Direto de Hortaliças (SPDH) surgiu na década de 1990 e é caracterizado no seu eixo técnico-científico pela promoção da saúde da planta com base na rotação de culturas, nos adubos verdes e animais manejados no Pastoreio Racional Voisin (PRV), nas adubações conforme as taxas diárias de absorção de nutrientes ajustadas pelo estoque de nutrientes no solo, nas condições climáticas e sinais de planta, no aumento do conforto das plantas pela minimização dos estresses e na diminuição até eliminação do uso de agrotóxicos e adubos altamente solúveis. O aprimoramento do SPDH vem ocorrendo, ao longo do tempo pelo trabalho conjunto de agricultores, extensionistas e pesquisadores, combinando conhecimento popular e técnico-científico em experiências com várias espécies hortícolas, cultivadas em diversas condições ambientais. Além de melhorar a técnica e economicamente os cultivos e criações, promove autonomia e valoriza o trabalho humano, com a produção de alimentos saudáveis, combinada com paisagens composta por suas lavouras, criações, corredores ecológicos e matas”.

Book excerpt: Food legumes are important constituents of the human diet and animal feed where they are crucial to a balanced diet, supplying high quality proteins. These crops also play an important role in low-input agricultural production systems by fixing atmospheric nitrogen. Despite systematic and continuous breeding efforts through conventional methods, substantial genetic gains have not been achieved. With the rise in demand for food legumes/pulses and increased market value of these crops, research has focused on increasing production and improving the quality of pulses for both edible and industrial purposes. "Biology and Breeding of Food Legumes" covers the history, origin and evolution, botany, breeding objectives and procedures, nutritional improvement, industrial uses and post-harvest technology and also recent developments made through biotechnological intervention.

Available in PDF, EPUB and Kindle. Book excerpt: Carbon stabilization involves to capturing carbon from the atmosphere and fix it in the forms soil organic carbon stock for a long period of time, it will be present to escape as a greenhouse gas in the form of carbon dioxide. Soil carbon storage is an important ecosystem service, resulting from interactions of several ecological processes. This process is primarily mediated by plants through photosynthesis, with carbon stored in the form of soil organic carbon. Soil carbon levels have reduced over decades of conversion of pristine ecosystems into agriculture landscape, which now offers the opportunity to store carbon from air into the soil. Carbon stabilization into the agricultural soils is a novel approach of research and offers promising reduction in the atmospheric carbon dioxide levels. This book brings together all aspects of soil carbon sequestration and stabilization, with a special focus on diversity of microorganisms and management practices of soil in agricultural systems. It discusses the role of ecosystem functioning, recent and future prospects, soil microbial ecological studies, rhizosphere microflora, and organic matter in soil carbon stabilization. It also explores carbon transformation in soil, biological management and its genetics, microbial transformation of soil carbon, plant growth promoting rhizobacteria (PGPRs), and their role in sustainable agriculture. The book offers a spectrum of ideas of new technological inventions and fundamentals of soil sustainability. It will be suitable for teachers, researchers, and policymakers, undergraduate and graduate students of soil science, soil microbiology, agronomy, ecology, and environmental sciences
