Abstract
- Highlights: [•] Leaching characteristics of a paddy field with straw retention were monitored in situ. [•] Nitrogen and phosphorus leaching losses under different N application rates with straw retention were evaluated. [•] The percolation rate declined with time after rice transplanting in first-order index attenuation. [•] N leaching occurred mainly at basal fertilization stage and straw incorporation reduced N leaching but stimulated P leaching. [ABSTRACT FROM AUTHOR]
