“…In the context of oil plantation management, the stratification of soil diversity was necessary to facilitate the best practice maintenance since it correlated to efficient investment for fertilization cost (Rhebergen et al 2020). The identical cluster indicated similar soil properties in the site (Moharana et al 2020). Thus, it could be managed using equal treatment.…”

“…CaO amounts necessary to increase the pH value from a suboptimal range (lime supply statuses A and B) to the optimum pH range (lime supply status C), as recommended by the VDLUFA approach (CaOVDLUFA, see Figure 3), in comparison to the CaO amounts predicted by the stepless approach (CaOModel). Regarding the lime supply status C, the task was to relate the lime recommendation linearly to the pH, decreasing from the lowest CaO amount recommended in lime supply status B to zero as recommended if the pH achieves lime supply status D. Therefore, the upper pH limits of the lime supply statuses B (pHmax_B) and C (pHmax_C) were applied according to Equations ( 4) and (5). The minimum CaO demand (CaOmin_B) of lime supply level B, which refers to its maximum pH (pHmax_B), can be calculated from Equations (2), ( 7) and (8).…”

“…Therefore, it can be economically and environmentally inefficient [1]. Sitespecific management, as an intrinsic part of precision agriculture, contributes to increasing yield, reducing inputs, and minimizing environmental impact [2][3][4][5][6][7]. However, the benefits of site-specific management strategies are strongly dependent on the quality of the variability prediction.…”

“…Generally, MZ delineation approaches can be categorized based on the provided data and information from different sources [2]. These methods are generally based on farmers' knowledge [20], soil physical and chemical attributes [21][22][23][24], geomorphology [25], yield [26][27][28][29][30][31], electrical conductivity (EC) [32,33] and RS [17,34,35] data, and also hybrid models that combine information from different data sources [36][37][38][39][40][41][42][43][44][45][46][47].…”
