MATERIAL FOR FERTILIZATION, MOLDED BODY FOR FERTILIZATION, AND METHOD FOR FERTILIZATION

PROBLEM TO BE SOLVED: To provide a utilization of unutilized residual waste materials from forest industry, an easy and effective fertilization technique especially for the soil of sloped ground in an orchard, etc., which is hard to deeply cultivate, and a technique for promoting greening of a steep slope face, which is also applicable to stabilization of a slope face. SOLUTION: The unutilized residual waste materials, which are thinned wood, improvement- cut wood, branches and leaves, etc., from the forest industry (1a) and bark, sawdust, etc., from wood processing industry (1b), are crushed into ligneous crushed chips (P1). The residual waste materials or the crushed chips are carbonized and formed into the carbonaceous materials of granule and powder (P2). The ligneous crushed chips, the carbonaceous materials, and microorganisms 3 are mixed (P3). Substituted for or added to the microorganisms, fallen leaves, etc., carrying microorganisms or fermented compost obtained by fermenting and aging (PA1, PA2) organic waste 2 may be mixed. A columnar molded body for fertilization having a center through-hole is formed by extruding the mixed material through an extruder. Microorganisms may be filled in the center through-hole. Boreholes are formed in the soil around a fruit tree with an earth auger, and the molded body for fertilization is built up and buried in the borehole. Thus, a self-composting column which itself is gradually composted due to the activity of the microorganisms is formed in the soil.
