Popis: A greenhouse experiment was conducted to determine the effect of rice straw residue on growth and uptake of added 15N‐labeled ammonium nitrogen (NH4‐N) (3% 15N abundance at the rate of 150 kg N ha−) by rice in Crowley silt loam soil (Typic Albaqualfs). Higher rates of rice straw addition had an adverse affect on plant growth from the first to sixth week. After 6 weeks, the high rice straw treatment had a positive effect on plant growth (P
