Application of local resource-based amelioration technology on the chemical properties of Inceptisols in monoculture and polyculture cultivation systems

Abstract The impact of using chemical fertilizers in the cultivation system changes soil’s physicochemical characteristics. Local resources-based amelioration technology can be used as a solution to increase soil fertility and plant productivity. This study aimed measure properties Inceptisols monoculture polyculture systems. A randomized block design was this research with eight treatments three replications. Treatments were carried out equivalent doses: control; bamboo biochar (BB)+ Tithonia green fertilizer(TGF)+manure+compost; BB+TGF+manure; BB+TGF+compost; BB+manure+compost; TGF+manure+compost; conventional technique Ministry Agriculture recommendation (MAR). results showed that addition ameliorant tended have higher pH than control. highest organic-C obtained TGF+manure+compost, which 0.39; 0.49; 0.47 more elevated compared control, technique, MAR. Meanwhile, found BB+TGF+manure almost same BB+manure+compost, but by 1.15, 1.01, 1.01 conventional, available-P for all treatments, while system, MAR values others.
