中文摘要 過量使用化學肥料會導致土壤酸化並增加溫室氣體之排放,相反的,農地施用有機質肥料不但可以將農業廢棄物再利用,也可以提升土壤品質。本研究將兩種雞糞製成之有機質肥料(G508G509)以一倍或是兩倍的氮素推薦量用於田間土壤,並種植三種作物,試驗結果顯示,由於G508並未經過堆肥化之過程,因此比G509有較高的氮素含量,因此導致G509處理下之總無機態氮釋放量低於G508處理。與化學肥料處理比較,失用兩種有機質肥料皆可以提升土壤之pH、有機質、有效性磷及交換性鉀鈣鎂濃度,在G508X2的處理下,作物之產量甚至高於化學肥料處理組。透過本研究可以發現,儘管G508G509皆使用雞糞進行製作,但兩者的養分釋放行為及對土壤與作物生長之影響並不相同。
英文摘要 (1) Background: Excessive use of chemical fertilizers accelerates soil acidification and increases greenhouse gas emissions. In this context, the farmland application of organic fertilizers not only reuses agricultural waste but also improves soil quality. (2) Methods: Two organic fertilizers made from chicken manure—G508 and G509—were field applied, implementing once or twice (denoted by X1 and X2, respectively) the recommended amount of nitrogen for three crops. In addition, an incubation experiment was conducted to assess the mineralization of the organic fertilizers. (3) Results: G508 did not undergo a composting process and, thus, had a higher content of nitrogen compared to G509. Therefore, although the soil properties improved under G509, the total mineral nitrogen released was lower than G508. Compared to chemical fertilizer treatment, the application of G508 and G509 increased the soil’s pH value, concentrations of organic matter, available phosphorus, and exchangeable concentrations of potassium, calcium, and magnesium. In addition, the crop yield under G508X2 treatment was even higher than that under chemical fertilizer treatment.
(4) Conclusions: Although G508 and G509 were both processed using chicken manure, they exhibited different nutrient-release behaviors during mineralization and also had different influences on the soil properties and growth of the three crops.
發表成果與本中心研究主題相關性 本研究之主題與農業廢棄物再利用相關,雞糞之處理是現階段農業廢棄物所面臨之問題之一,使用雞糞以不同製程製成的有機質肥料,其在養分釋放行為上的差異,會影響到土壤性質及作物之生長表現,本研究之結果可以供農民選擇有機質肥料之參考。
