摘要: Abstract Loss of soil‐water saturation may impair growth rainfed lowland rice by restricting nutrient uptake, including the uptake added phosphorus (P). For acidic soils, reappearance soluble aluminum (Al) following loss also restrict P uptake. The aim this study was to determine whether liming, flooding, and additions could ameliorate effects on rice. In first pot experiment, two acid soils from Cambodia [Kandic Plinthaqult (black clay soil) Plinthustalf (sandy soil)] were treated with (45 mg P kg−1 either before or after flooding for 4 weeks investigate effect effectiveness fertilizer growth. After weeks, air dried crushed then wet field capacity upland grown in them an additional 6 weeks. Addition rather than depressed subsequently planted ...
