Compositions are provided comprising pyrolysis carbon and humus containing materials to prevent wasteful water loss in turf grass applications by reducing evaporation, decreasing root zone and surface runoff, storing the water in the soil between irrigation events, and by increasing plant rooting depth enabling access to deeply held water in the soil; and methods for making and using the same.

Disclosed is a method for reducing methane emission from slurry (2) produced in a livestock farm (1). The method comprises the steps of guiding the slurry (2) from the livestock farm (1) to a dewatering unit (12) in which the slurry (2) is at least partially dewatered by extracting a watery fraction of said slurry (13), guiding the slurry from the dewatering unit (12) to a steam dryer (3), drying the slurry in the steam dryer (3), guiding the dried slurry (4) into a pyrolysis reactor (5) to produce pyrolysis gas (6) and biochar (7) through a pyrolysis process in the pyrolysis reactor (5), guiding at least a portion of the pyrolysis gas (6) to a combustion unit (8) in which the pyrolysis gas portion is combusted to raise the temperature of the combusted pyrolysis gas (9), guiding the combusted pyrolysis gas (9) to the pyrolysis reactor (5) to drive the pyrolysis process, guiding the combusted pyrolysis gas (9) from the pyrolysis reactor (5) to the steam dryer (3) to increase the temperature of steam (10) in the steam dryer (3), and heating the watery fraction of the slurry 13 to a temperature at least above 75° Celsius by means of the steam (10) from said steam dryer (3). Furthermore, a slurry treatment plant (20) for reducing methane emission from slurry (2) is disclosed.

Provided is a powder body obtained from a water-containing organic matter having a moisture content of 20% or less, a bacterial count of mesophilic aerobic bacteria of 10.sup.5/g or less, and a maximum exothermic peak by a differential thermal analysis method of 300° C. or higher.
