Sustainability of phosphorus fertilisation: sources and forms of phosphate

Abstract: A B S T R A C TPhosphorus (P), which originates from a non-renewable natural resource, is essential for crop productivity, food security and human health. Despite being a finite resource its use has been increasing consistently over the last few decades. The major use of the phosphate rock is the manufacture of P fertiliser, agriculture also being the main source for nonpoint source P pollution, which causes the eutrophication of water bodies. Thus, there is great need for a sustainable use of P with special a… Show more

“…As políticas sustentáveis, aplicadas ao uso do P, devem levar em consideração três aspectos básicos. O primeiro deles refere-se ao fato de que este nutriente é vital para todos os organismos, não possuindo outro elemento que possa substituí-lo (Ashley et al 2011;Desmidt et al 2015;Horta 2015). No segundo, pontua-se que as excreções animais e a erosão e lixiviação do solo representam os dois maiores fluxos de perda do P com 40% e 46% do P extraído, respectivamente (Rittmann 2011).…”

“…O fósforo (P) é um dos elementos presentes no ES pós biodigestão que mais contribui para o evento da eutrofização de rios e lagos (Klein e Agne 2012;Bali e Gueddari, 2019). Por outro lado, o nutriente é um recurso natural, não renovável, indispensável para a presença e manutenção de todas formas de vida na Terra, sendo desconhecido algum ser vivo que não o utilize em algum processo (Domingos et al 2003;Horta 2015). Portanto, é fundamental para o agronegócio, para o fornecimento de alimentos e para a saúde humana (Suh e Yee 2011).…”

“…Natural phosphate is originated from igneous or metamorphic rocks and exhibit low reactivity and low solubility in water and acid solutions. The sedimentary material exhibits high reaction with isomorphic compounds for replacement in their structures to reach greater reactivity (Soares et al, 2000;Horta, 2015). Brazilian soils have low amount of phosphorus which generally is not present in available forms.…”
