In detail this study addressed the following questions: (i) Are mineral N, P and K fertilizers absorbed by charcoal? (ii) To what degree are the absorbed or chemically bound nutrients available to plants and/or microorganisms? and, (iii) Does charcoal increase the retention of mineral N and K fertilizers?  aAmazonia  aFertilidade  aSolo  aUso da Terra  aBrasil  aCultivo1 aGARCIA, M.1 aZECH, W.  tIn: STEINER, C.
