Abstract

Material indicators are important in sustainable production to decrease resource use and environmental impacts and increase economic productivity. The present research aims to calculate material indicators of chemical fertilizers in crop production systems in Iran. Material intensity and productivity for nitrogen, phosphor, and potassium were calculated from 1980 to 2016. Cereal, pulse, oilseed, tuber, and fiber were the studied crops. The mean production value in all systems was 4.40 ton.ha⁻¹, which had an increasing trend from 1980 to 2016. The mean of material intensity for the fertilizers in all production systems were 2.19, 1.04, and 0.16 kg.ton⁻¹, respectively while the mean values of the material productivity were 0.52, 1.16, 13.39 ton.kg⁻¹, respectively. The productivity of all studied fertilizers had an increasing trend while it had a decreasing trend for phosphor and potassium in recent years. The results of the present research can be used to optimize fertilizer consumption and consequently decrease production costs and environmental impacts.

伊朗种植五种主要作物的化肥消耗和生产力的长期趋势

物质指标对可持续生产很重要，可以减少资源使用和环境影响，提高经济生产力。本研究旨在计算伊朗作物生产系统中化肥的物质指标。从1980年到2016年，计算了氮、磷和钾的材料强度和生产率。谷物、豆类、油籽、块茎和纤维是研究的作物。所有系统的平均产值为4.40吨。Ha−1,1980 ~ 2016年呈增加趋势。各生产系统的肥料物质强度平均值分别为2.19、1.04和0.16 kg。的平均值分别为0.52、1.16、13.39 Ton。公斤−1,分别。近年来，各肥料的生产力均呈上升趋势，而磷和钾的生产力则呈下降趋势。本研究结果可用于优化肥料消耗，从而降低生产成本和环境影响。
