Improving soil quality and plant productivity is still challenging in sustainable agriculture. The purpose of this research was to obtain sustainable crop management in effort to improve soil quality and increase maize production through the evaluation of the functioning of liquid bio-ameliorant in reduction of chemical fertilizer utilization. Factorial experimental design with three treatment factors and three replications applied and Duncan multiple range test was used to analysis the effect of treatment on all parameters evaluated.The treatment consists of two levels of planting space and three levels of liquid bio-ameliorant and nitrogen fertilizer in each. The result shown in soil quality parameters such as microbial density was increased approximately 28% and soil chemical properties was indicated improved in combining liquid bio-ameliorant and reducing nitrogen fertilizer application. In the same line, a significant improvement of biological yield was found in plant height, number of plant leaves, biomass weight, and content of plant nutrient parameters. The highest production of 9.00 ton/ha as the result of application 300 ml/l bio-liquid ameliorant + urea 240kg/ha. Based on the result achieved the great potential of liquid bio-ameliorant to reduce chemical fertilizer and useful to sustain crop production and improve soil quality.
