<P>PROBLEM TO BE SOLVED: To rehabilitate a degraded land by blowing a medium- to long-term stable greening material onto a land to be planted with trees relating to an artificial humus soil mixed greening process, and to provide the artificial humus soil to be blown by a blower against the surface of the target land for promoting humification. <P>SOLUTION: Organic matter has a content of approximately 70%. An organic material such as immature bark compost, sawdust, rice straws, rice husks and dehydrated cakes is soaked for five hours or longer in an extremely strong acid solution such as a sulfuric acid solution, hydrochloric acid and acetic acid with a mol concentration of 1.0 molL<SP POS="POST">-1</SP>(pH2) to 18.0 molL<SP POS="POST">-1</SP>(pH0), or is osmosed for approximately 100 hours in smoked powdery or coarse granular smoked carbon. In addition, the bark compost serving as the immature organic material with a C/N ratio of 35 or less, a mol concentration of 1.0 molL<SP POS="POST">-1</SP>(pH2) to 18.0 molL<SP POS="POST">-1</SP>(pH0) or pH(H<SB POS="POST">2</SB>O) of 5.5-7.5 and a value of electric conductivity of 0.9 mS/cm or lower is used. <P>COPYRIGHT: (C)2012,JPO&INPIT |
