Contrairement aux cultures telles que le caf , les agrumes et l'ananas, il existe peu d'informations sur l'utilisation d'engrais liquides pour les cultures c r ali res telles que le soja et le ma s, ainsi que pour les p turages. Pour combler cette lacune, une recherche a t d velopp e au Centre de recherche et de d veloppement avanc sur l'h v a et les syst mes agroforestiers de l'Institut agronomique (IAC) de l'Agence de S o Paulo pour la technologie agroalimentaire (APTA), qui est situ dans le biome du Cerrado dans la municipalit de Votuporanga, dans l' tat de S o Paulo, au Br sil. Cette recherche a donn naissance ce livre.

A differenza di colture come il caff , gli agrumi e l'ananas, ci sono poche informazioni sull'uso di fertilizzanti liquidi per il suolo per le colture da granella come la soia e il mais e per i pascoli. Per colmare questa lacuna stata sviluppata una ricerca presso il Centro di Ricerca e Sviluppo Avanzato per l'Albero della Gomma e i Sistemi Agroforestali dell'Istituto Agronomico (IAC) dell'Agenzia di San Paolo per la Tecnologia Agroalimentare (APTA), che si trova nel bioma del Cerrado nel comune di Votuporanga, Stato di San Paolo, Brasile. Da questa ricerca nato questo libro.

Nachhaltige landwirtschaftliche Produktionssysteme werden zunehmend erforscht, verbreitet und von Erzeugern in aller Welt bernommen. In diesem Buch werden die Ergebnisse von Untersuchungen vorgestellt, die in der nordwestlichen Region des Bundesstaates S o Paulo (Brasilien) durchgef hrt wurden. Dabei ging es um nachhaltige Sojaproduktionssysteme wie das System der Direktsaat auf Deckfr chten und auf Zuckerrohrstroh sowie um die Sojaproduktion in integrierten Produktionssystemen wie dem integrierten Pflanzenbau-Viehbestand und dem integrierten Pflanzenbau-Viehbestand-Wald.

Les syst mes durables de production agricole sont de plus en plus tudi s, diffus s et adopt s par les producteurs du monde entier. Cet ouvrage pr sente les r sultats de recherches men es dans la r gion nord-ouest de l' tat de S o Paulo (Br sil), portant sur des syst mes durables de production de soja, comme le syst me sans labour sur des cultures de couverture et sur la paille de canne sucre, ainsi que sur la production de soja dans des syst mes de production int gr e comme la culture- levage int gr e et la culture- levage-for t int gr e.

Os sistemas sustent veis de produ o agr cola t m sido cada vez mais estudados, divulgados e adotados por produtores de todo o mundo. Este livro apresenta resultados de pesquisas realizadas na regi o Noroeste do Estado de S o Paulo (Brasil), envolvendo sistemas sustent veis de produ o de soja, como o sistema de plantio direto sobre culturas de cobertura e sobre a palhada da cana-de-a car, e tamb m a produ o de soja em sistemas integrados de produ o, como a integra o lavoura-pecu ria e a integra o lavoura-pecu ria-floresta.

I sistemi sostenibili di produzione agricola sono sempre pi studiati, diffusi e adottati dai produttori di tutto il mondo. Questo libro presenta i risultati di ricerche condotte nella regione nord-occidentale dello Stato di San Paolo (Brasile), che hanno riguardato i sistemi di produzione sostenibile della soia, come il sistema no-tillage su colture di copertura e sulla paglia di canna da zucchero, e anche la produzione di soia in sistemi di produzione integrata come coltura-zootecnica integrata e coltura-zootecnica-foresta integrata.

Zr wnoważone systemy produkcji rolnej są coraz częściej badane, rozpowszechniane i przyjmowane przez producent w na calym świecie. Niniejsza książka przedstawia wyniki badań przeprowadzonych w p lnocno-zachodnim regionie stanu S o Paulo (Brazylia), obejmujących zr wnoważone systemy produkcji soi, takie jak system uprawy bezorkowej na roślinach okrywowych i slomie trzciny cukrowej, a także produkcję soi w zintegrowanych systemach produkcji, takich jak zintegrowana uprawa-zwierzęta i zintegrowana uprawa-zwierzęta-leśne.

In this book, we will show the results of three researches about soil chemical quality developed in the Northwest S o Paulo State, Brazil. On our first research, we evaluated the changes in soil chemical attributes in an organic agroforestry system using four cover crops and a standard treatment without cover crop. On the second research, we evaluated the changes in soil chemical attributes in an agropastoral system with use of silicate agrominerals as a soil remineralizer to replace the use of limestone, gypsum, and conventional mineral fertilizers. On the third research we evaluated the the changes in soil chemical attributes in a rubber tree cultivation with use of silicate agrominerals.

Ao contr rio de culturas como caf , citros e abacaxi, h poucas informa es sobre o uso de fertilizantes l quidos no solo para culturas produtoras de gr os, como soja e milho, e em pastagens. Para suprir essa lacuna foi desenvolvida uma pesquisa no Centro Avan ado de Pesquisa e Desenvolvimento de Seringueira e Sistemas Agroflorestais do Instituto Agron mico (IAC) da Ag ncia Paulista de Tecnologia dos Agroneg cios (APTA), que est localizado no bioma Cerrado, no munic pio de Votuporanga, Estado de S o Paulo, Brasil. Esta pesquisa deu origem a este livro.

Im Gegensatz zu Kulturen wie Kaffee, Zitrusfr chten und Ananas gibt es nur wenige Informationen ber den Einsatz von fl ssigem Bodend nger bei Getreide produzierenden Kulturen wie Sojabohnen und Mais sowie bei Weiden. Um diese L cke zu schlie en, wurde eine Forschungsarbeit am Advanced Research and Development Center for Rubber Tree and Agroforestry Systems des Agronomischen Instituts (IAC) der S o Paulo Agency for Agribusiness Technology (APTA) durchgef hrt, das im Cerrado-Biom in der Gemeinde Votuporanga im brasilianischen Bundesstaat S o Paulo liegt. Aus dieser Forschung ist das vorliegende Buch entstanden.

In Brazil the cultivation of soybean is almost all done under no-till system, and the soybean is the Brazilian culture with fastest growing in the last three decades and corresponds to 49% of the grain planted area in Brazil. The increasing productivity is associated to technological advances, the management and efficiency of producers. Cultivated especially in the Midwest and South regions, soybean has established itself as one of the leading products of domestic agriculture and trade balance. Soybean was responsible for the formation of a complex structure of production, storage, processing and marketing in all countries where it is growing on a large scale. The great demand in the international market provided rapid expansion of this crop in Brazil, which occurred by the replacement of other cultures by soybean culture, and especially by the conquest of new agricultural frontiers. In relation to nitrogen fertilization efficiency in soybean crop, there are many doubts about the subject. In some situations, as in production systems under no-till with a high amount of straw on the soil, nitrogen fertilization can reduce the problem of nitrogen deficiency and also increase soybean crop yield, however, there is a limit of dose of nitrogen to be used and the soybean grain yield increase and the soybean price must compensate the nitrogen fertilization investment. This book will present results of researches conducted in the Northwest region of S o Paulo State (Brazil), involving nitrogen fertilization in soybean under no-till system on the straw of sugarcane and on the straw of forage sorghum intercropped with Congo grass.
