B. de FARIA and published by . This book was released on 1981 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foram analisados 57 experimentos instalados em vários locais do Nordeste durante os anos de 1974 a 1979 com os seguintes objetivos: a) avaliar a influência da aplicação de fertilizantes no rendimento da cultura do milho; b) obter informações para calibração de análise de solo; c) estimar doses econômicas de adubação; d) verificar quais as características do solo que influem na produção. Apenas nitrogênio e fósforo tiveram efeitos significativos na produção do milho. Com o uso desses nutrientes foram obtidos incrementos na produtividade que variaram desde 37 ate 1,137%. Os níveis econômicos de adubacao nitrogenada variaram de 78 a 139 kg/ha de N com uma média de 109 kg/ha de N,. Obtiveram-se níveis críticos de fósforo no solo com valores médios de 8,7 ppm de P pelo extrator de Mehlich e de 7,5 ppm de P pelo extrator de Bray- 1 e ajustaram-se regressões entre o fósforo aplicado ao solo e o fosforo extraido por ambos os extratores. A analise pelo procedimento "stepwise" indicou que das onze variáveis do solo testadas, apenas a fração silte e o potássio trocável influiram na produção do milho, cuja influência foi positiva.

This book was released on 1967 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estudo realizado de calibracao de analise de solo com respostas da cultura do milho aos fertilizantes fosfatados e potassicos em experimentos de campo correlacionando-se producoes relativas de treze experimento de campo correlacionando-se producoes relativas de treze experimentos, instalados em diversas areas fisiograficas do Nordeste versus analise quimica do solo utilizando-se o metodo de extracao e determinacao da Universidade estadual da Carolina do Norte (USA). O objetivo da pesquisa foi desenvolver um metodo rapido de interpretacao e analise de solo para as "condicoes de solo-clima-planta do Nordeste", que possiblitasse chegar ate as causas que afetam a fertilidade quimica do solo, limitando a produtividade agricola e corrigindo-as.
