“…and human activities (fertilization, irrigation, and crop rotation etc.) directly, indirectly, synergistically or antagonistically affected the quality of grain production space (Leonard et al, 2020;Kurmangozhinov et al, 2020;Jin et al, 2021). Hence, it was di cult to establish a uni ed standard to evaluate the quality of grain production space (Fu and Bai, 2015).…”

“…The combination of Principal Component Analysis (PCA) with Norm Value Determination was used to obtain the pivotal constitutors (or indicators) of the soil MDS from the soil TDS (Yu et al, 2018;Tian et al, 2020). The grouping process of the PCA was referred to Jin et al (2021b). Norm Values are the comprehensive loadings of given indicators across all components, which were calculated to screen the indicators.…”

“…However, the cultivated land supplemented by land improvement has serious quality problems that are prominently manifested in the lack of high-quality farming layers [6], leading to the balance policy of arable land occupancy compensation, which equalizes the existence of "predominantly superior and compensating inferiority". The fertile farming layer, also called the high quality farming layer, is formed through long-term cultivation, and is characterized by obvious soil aggregate structure, high organic matter content and microbial activity, and strong feeding ability [7]. Timeliness indicates that newly reclaimed cultivated land cannot be replaced after many years of cultivation.…”
