The invention provides a non-fertilizer-nutrient effect evaluation method. The method comprises the steps of arranging a non-fertilization region in the field to be tested, and measuring the area of the region; measuring the soil available nutrient element content and the soil available nutrient element buffer value before planting; applying no fertilizers during the whole production period, and following regular practices in other aspects; measuring nutrient element absorbing capacity of crops without fertilization during crop harvesting; analyzing and measuring the soil available nutrient element content after harvest; calculating the plough layer soil weight; calculating the soil available nutrient element sum change values; calculating non-fertilizer-nutrient effect values; performing evaluation according to the obtained non-fertilizer-nutrient effect values. According to the method, non fertilizer nutrients are regarded as a whole, actual contribution of nutrients except fertilizers to crop production is evaluated by measuring the non-fertilizer-nutrient effect values, a significant reference base is provided for fertilizer and fertilization decisions, and the method can be used for fertilization effect evaluation and soil testing recommended fertilizer amount calculation.
