文摘

Phosphorus-containing fertilizers play an important role in tropical agriculture owing to the well documented shortage of plant-available P in soils. Traditional P fertilizer production is based on chemical processing of insoluble rock phosphate (RP), which includes an acid treatment at high temperature. Processing the RP increases fertilizer costs, making it unavailable for undercapitalized and typically family-based farmers. Biotechnological methods have been proposed as an alternative to increase phosphate availability in RP. In this study, Burkholderia silvatlantica and Herbaspirillum seropedicae were co-inoculated into an RP-enriched compost with the aim of determining the effects of this technology on the levels of phosphatase activities and release of plant-available P.
