大規模トマト施設生産から排出されるトマト残渣量の推定とその堆肥化物の諸性質

It was estimated 11.6 kg・m^2 of leaves and 8.7kg・m^2 of fruits were released from the year-round tomato production at the rate of 40kg・m^2. Even though there will be some difference among the tomato varieties, one third of assimilate was discarded as the wastes by production, which was consisted of 60% of leaves and 40% of fruits. Compost of 0.75m^3 (308kg wet matter) was produced within this term (ten weeks), whose volume and weight were reduced by the half and 17% of initial amount, respectively. Temperature at the center of the secondary compost synchronized with air temperature with almost half-day delay, which meant the compost temperature was little increased by secondary fermentation. Inhibitory factor in germination have not been recognized on the every tested composts from tomato residues (tomato compost). Because tomato compost resembled to commercial bark compost in the water holding characteristics and mineral contents, the application of this compost was assumed as soil conditioner or medium for hydroponics. It is estimated that 49gN1・m^2 and 5.5kg CO_2・m^2 were released from tomato composting process on a year-round production. Simultaneously, 21g P・m^2 was also generated as am anure from this process.
