Crescimento de leguminosas forrageiras afetado pela adição de fósforo, calagem do solo e micorrizas, em condições de casa de vegetação

Abstract: A contribuição de leguminosas forrageiras na produtividade das pastagens nativas de solos ácidos e com baixa disponibilidade de fósforo é pequena e limitada a algumas espécies. Este trabalho tem o objetivo de avaliaro efeito da acidez da adição de fósforo e da micorrização no crescimento do trevo riograndense, desmódio e cornichão. Para tanto foram instalados quatro experimentos em casa de vegetação, sendo dois em Lages (SC), com amostras de Latossolo bruno argiloso e, dois em Santa Maria (RS) com Podzólico Ve… Show more

“…Moreover, they are naturally acid soils (pH 4.4-5.1) and this feature leads to high-energy P adsorption onto soil clay minerals and oxides, as well as reduces natural soil P availability to plants (e.g., Mehlich-1 method), which often ranges from 2 mg kg -1 to 8 mg kg -1 (Oliveira et al, 2011;Rheinheimer et al, 1997).…”

“…Well managed rangelands of Pampa can reach a dry matter production around 14 Mg ha -1 year -1 (Oliveira et al, 2015); in contrast, in areas with inadequate management, the productions achieve averages between 3.7 Mg ha -1 year -1 (Soares et al, 2005) and 9.8 Mg ha -1 year -1 (Pellegrini et al, 2010). The principal causes of low productivity is high soil acidity (pH ~ 4.4) and low fertility, such as reduced available P (2.6 to 7.6 mg of P kg -1 ), especially in soils of Southern Brazil (Oliveira et al, 2011;Rheinheimer et al, 1997;Tiecher et al, 2014). In the scenario of low fertility, an increase of nutrients availability by limestone and phosphorus fertilizers are important strategies to support plant development (Gatiboni et al, 2000;Prestes et al, 2017Prestes et al, , 2016.…”
