The technique of fertilizer consumption increases yields from agriculture, but because it involves chemicals, there are disagreements regarding how it affects the environment. Based on this, the aim of this study is to investigate the effects of fertilizer consumption on load capacity factor in Turkey through novel technique (multivariate quantile-on-quantile regression) for the period 1970–2021. In this regard, factors that have significant effects on the environment, such as trade globalization, renewable energy usage, natural resources, are also included in the empirical model to avoid omitted variable bias. In addition, real national income and the square of real national income are also included in the model to check the validity of the possible load capacity curve (LCC) hypothesis. According to the findings of the study, a U-shaped relationship between economic growth and environmental quality is valid, thus proving the existence of the LCC hypothesis. Additionally, trade globalization and fertilizer consumption appear to increase environmental damage. On the other hand, renewable energy consumption increases load capacity. In addition, Kernel-based regularized least squares technique is used for robustness control. According to the findings obtained from here, 1 % increase in fertilizer consumption reduces the load capacity factor by 0.03 %. Based on the findings, policy recommendations are made to provide subsidies or financial incentives for the use of organic fertilizers and biofertilizers. Indeed, these alternatives can increase load capacity by improving soil health and reducing chemical runoff.
