Abstract: RESUMOA fertilidade dos solos das regiões tropicais é limitada pela baixa disponibilidade de fósforo e pela indisponibilização de boa parte do mesmo fornecido na adubação. Ainda existem muitas divergências sobre a melhor forma de utilização das diversas fontes fosfatadas disponíveis no Brasil. Objetivou-se, neste experimento, avaliar a produção de soja, sob a aplicação de diferentes doses e adubos fosfatados em dois tipos de solo. O trabalho foi realizado em casa de vegetação do Departamento de Ciência do Solo… Show more

“…Phosphorus use efficiency depends on several factors, among others, soil management, the type of fertilizer (source of P, solubility, composition, and richness in P), and the application method (Resende et al 2006;Motomiya et al 2004;Zhang et al 2019). Both factors affect soil P availability and, as a result, crop yield (Montoniya et al 2004;Silva et al 2009;Sá et al 2013;Vieira et al 2013Vieira et al , 2015Valadão et al 2017). The application of P fertilizers to the soil surface is the most common practice, which has a reduced economic cost in comparison with other methods (Olibone and Rosolem 2010) but it is not always the best alternative for plant nutrition and the environment.…”

“…The P derived from fertilizers with high solubility (in water and neutral ammonium citrate), such as triple superphosphate (TSP), may be readily transformed into forms unavailable to plants, and the fertilizer efficiency may be reduced over time (SILVA et al, 2009). On the other hand, the efficiencies of water-insoluble phosphate fertilizers, such as rock phosphate (RP) and magnesium termophosphate (MTP), tend to increase over time.…”

“…Alguns fatores importantes para absorção P a serem considerados são as características morfológicas e de arquitetura da raiz (WANG et al, 2010), densidade de pelos radiculares, simbiose com fungos micorrízicos, valores de pH da rizosfera, e capacidade de emissão e tipos de exsudatos radiculares (MARSCHNER 1986;HOCKING et al, 1997). SILVA et al, 2009).…”
