X1, temperature; X2, water availability; X3, oxygen availability; X4, rooting condition; X5, nutrient retention; X6, nutrient availability; X7, sodicity; X8, erosion hazard; X9, flooding hazard; X10, land preparation; Y, hybrid maize yield; X1.1, temperature; X2.1, rainfall; X2.2, the wet month; X2.3, the dry month; X2.3, long growth period; X3.1, drainage; X4.1, texture; X4.2, coarse material; X4.3, effective depth; X5.1, organic C; X5.2, cation exchanges capacity; X5.3, base saturation; X6.1, total N; X6.2, P availability; X6.3, K exchangeable; X7.1, the exchange sodium percentage; X8.1, slopes; X8.2, soil erosion; X9.1, inundation height; X9.2, inundation period; X10.1, rock outcrops; X10.2, surface rock; Y.1, hybrid maize yield. The yellow color shows the loading factor value for the indicators of the latent variables above the loading factor values for other latent variable indicators (>0.5), while the red color indicates the opposite (<0.5).
