Book excerpt: A zona da mata esta situada no dominio morfologico da Mata Atlantica, na regiao sudeste de Minas Gerais, Brasil, Este dominio acompanha a costa brasileira de norte a sul e esta entre os cinco dos 25 "pontos quentes" da biodiversidade, que ssao as areas de maior biodiversidade vegetal e animal e mais ameaçadas do planeta. Originalmente a Zona da Mata era coberta por florestas, restando atualmente cerca de 7.5% da cobertura original. Os agroecosistemas que se instalaram na regiao apresentam produtividade decrescente devido a intensificaçao do uso do solo, utilizando muitas vezes manejo inadequado. Em 1993, agricultores e pesquisadores, buscando alternativas agricolas mais sustentaveis iniciaram a implementaçao (ou melhoria) de sistemas agroflorestais com café (cultura de maior valor economico) na regiao, acompanhando a vocaçao natural daquele ambiente, originalmente florestado. Os principais objetivos da implantaçao de sistemas agroflorestais foiram: 1) regeneraçao e conservaçao dos solos; 2) diminuiçao do uso de insumos externos na agricultura; 3) aumento ou manuntençao dos niveis de produçao; e 4) melhoria da produtividade. E condiçao necessaria para atingir esses objetivos, a melhor compreensao da ciclagem de nutrientes no solo. O presente trabalho objetivou contribuir para melhorar a compreensao desse aspecto, com enfase no fosforo (p), por se tratasr de um nutriente essencial de baixa disponibilidade na maioria dos ecossitemas e que nos solos tropicais, altamente intemperizados , se constitui no principal limitsante da produçao agricola, A deficiencia em P e causada principalmente pela forte absorçao do H2PO, pelos (hidr)roxidos de aluminio (Al) e ferro (Fe), os quais indisponibilizam grande parte do P total para as plantas cultivadas. A principal estrategia para lidar com o problema da fixaçao de P no tropicos tem sido a adiçao de fertilizantes. Entretanto, e sabido que as reservas minerais de P, necessarias para a produçao de fertilizantes, são limitadas e tem previsao de se esgotar em torno de 100 anos, mantido o atual crescimento do uso de P. Nesse contexto, e necessario o desenvolvimento de estrategias sustentaveis de uso tanto do fertilizante fosfatado aplicado, como do P nativo do solo.Uma dessas estrategias consiste de sistemas agroflorestais.e; c) a raizofera destas arvores podem apresentar caracteristicas distintas, devido a liberaçao de diferentes exsudados, tais como acidos organicos e fosfatases.

Book excerpt: Great attention has been paid to reduce the use of conventional chemical fertilizers harming living beings through food chain supplements from the soil environment. Therefore, it is necessary to develop alternative sustainable fertilizers to enhance soil sustainability and agriculture productivity. Biofertilizers are the substance that contains microorganisms (bacteria, algae, and fungi) living or latent cells that can enrich the soil quality with nitrogen, phosphorous, potassium, organic matter, etc. They are a cost-effective, biodegradable, and renewable source of plant nutrients/supplements to improve the soil-health properties. Biofertilizers emerge as an attractive alternative to chemical fertilizers, and as a promising cost-effective technology for eco-friendly agriculture and a sustainable environment that holds microorganisms which enhance the soil nutrients' solubility leading a raise in its fertility, stimulates crop growth and healthy food safety. This book provides in-depth knowledge about history and fundamentals to advances biofertilizers, including latest reviews, challenges, and future perspectives. It covers fabrication approaches, and various types of biofertilizers and their applications in agriculture, environment, forestry and industrial sectors. Also, organic farming, quality control, quality assurance, food safety and case-studies of biofertilizers are briefly discussed. Biofertilizers' physical properties, affecting factors, impact, and industry profiles in the market are well addressed. This book is an essential guide for farmers, agrochemists, environmental engineers, scientists, students, and faculty who would like to understand the science behind the sustainable fertilizers, soil chemistry and agroecology.
