摘要: Decreases in nutrient availability after loss of soil-water saturation are significant constraints to productivity lowland rainfed rice soils. The effectiveness soil amendments like lime and straw ameliorating these poorly understood. This pot experiment was conducted Cambodia investigate changes chemical properties uptake by applying or continuously flooded intermittently soil. In soils, exchangeable Al decreased below 0.2 cmolc/kg. Liming (pH 6.5–6.8) the levels acetate extractable Fe P, plant P shoot dry matter, but had no effect on either Bray-1 Olsen values. By contrast, addition (3.5 g straw/kg soil) increased Bray-1, Olsen, uptake, matter. non-amended soils became strongly acidic water saturation: 1.0 cmolc/kg, a potentially harmful level for rice. markedly under as did With saturation, liming substantially depressed it not increase Straw only well 0.6 cmolc/kg also extractability Thus, environments, incorporation may be more effective than pH 6.8 minimising negative effects temporary availability, growth
