| 英文摘要 | A field experiment was conducted to study the outcome of N using isotope-labeled urea with a peanut cropping system in a Udic Ferrosol on a 7% slope at the Ecological Experimental Station of Red Soil, Chinese Academy of Sciences. The micro-plots were designed in two sets with three replicates and four N treatments. An iron frame with its edge 10 cm above the ground was used to control soil erosion and runoff in set A, but in set B the upper edge of the frame was level with the ground. Randomly positioned N-15 fertilized micro-plots were established along the contour. At harvest on August 13, 2002, which was four months after urea application, the peanuts had absorbed 30.6%-38.0% of the urea, transpired 13.1%-22.4% to the atmosphere, lost 6.4%-8.4% through soil erosion and surface runoff, and maintained 40.7%-48.9% in the 0-60 cm soil layer with 0.5%-5.0% below 60 cm. |
