ＹＰＭＧ培地に試験区のサンプルを濃度ごとに塗布し、メロンつる割れ病病原性 フザリウムが培養された５ｍｍ平方の寒天を培地の中央に乗せ３０℃で培養する。
フザリウム菌の成長阻害度を判定するため、コロニーの直径（最長・最短）の長さ を計測した。培養期間は一週間である。
Compost (land improvement material) obtained above [hereinafter referred to as "this example". ] Was investigated after putting 10 g in 90 ml of sterilized water and shaking for 30 minutes.
As a comparative example, Super Eco Compost (hereinafter referred to as “Comparative Example”) manufactured by Minamisuhara Development Co., Ltd. obtained by mixing livestock dung and peat was used.
1. Filamentous fungi and color-resistant bacteria were counted using rose bengal agar. Radioactive bacteria and bacteria were counted using egg albumin agar. Dilution was counted by the plate method.
2, pH, EC measurement It measured using the said shaking liquid.
3. Measurement of pathogen deterrence A sample of the test group is applied to the YPMG medium for each concentration, and 5 mm square agar on which melon vine crack pathogenic fusarium is cultured is placed on the center of the medium and cultured at 30 ° C.
To determine the degree of inhibition of Fusarium growth, the length of the colony diameter (longest and shortest) was measured. The culture period is one week.

上記のことから、
微生物性・・・本実施例のものの糸状菌は１０6オーダー、細菌は１０5オーダー、放 線菌は検出されなかった。
比較例のものの糸状菌は１０3オーダー、放線菌は１０5オーダー、細 菌は１０7オーダーであった。
病原抑止力・・・本実施例のものについては、１０6希釈液までフザリウム菌の伸長 が僅かしか確認されず、フザリウム菌に対する病原抑止能力が高か った。
これは、糸状菌による抑制が大きいことに起因すると考えられる。
比較例のものについては、１０2希釈液まではフザリウム菌の伸長 が短く、１０4希釈液以上は徐々に病原抑止能力が低下していった 。
From the above,
Microbial ... filamentous fungi according to the present example 10 6 orders, bacteria 10 5 orders were detected release Senkin.
The filamentous fungus of the comparative example was on the order of 10 3 , actinomycetes on the order of 10 5 , and bacteria on the order of 10 7 .
Pathogen deterrence power: In the case of the present example, only a slight extension of Fusarium bacteria was confirmed up to 10 6 dilution, and the pathogen deterrence ability against Fusarium bacteria was high.
This is thought to be due to the great suppression by filamentous fungi.
In the comparative example, the elongation of Fusarium bacteria was short up to a dilution of 10 2 , and the ability to suppress pathogens gradually decreased at a dilution of 10 4 or more.
また、泥炭と米糠（容積比 泥炭：米糠＝７：３）を混合させて発酵させた発酵体３ｍ3を汚泥３ｍ3に混合させたところ、汚泥の悪臭を軽減することができた。 Moreover, when the fermented material 3m 3 fermented by mixing peat and rice bran (volume ratio peat: rice bran = 7: 3) was mixed with sludge 3m 3 , the malodor of the sludge could be reduced.
