Filter Cake Biochar as a Soil Conditioner Cultivated with Native Cerrado Species: Effect on Soil Chemical and Microbiological Properties

The objective of this study was to evaluate the effect filter cake biochar on chemical and microbiological attributes a dystrophic red-yellow latosol cultivated with macaúba (Acrocomia aculeata), araçá (Psidium firmum) cajuzinho do cerrado (Anacardium humile), species native Cerrado. Thus, responses soil were evaluated 120 days after transplanting seedlings using four doses (1%, 2%, 4% 8% v/v) two control treatments (one correction fertilization other no fertilization). pH, contents calcium, magnesium, phosphorus, potassium, CTC, total microbial organic carbon nitrogen, C:N ratio. For soils three Cerrado species, 1% dose mineral that best conditioned during cultivation period promoted better response soil.
