Effects of Nitrogen Application Rate Reduction Combined with Biochar Amendment on Apple Yield and Quality, Photosynthetic Carbon Allocation, and Soil Carbon Retention
To investigate the combined effects of a reduced nitrogen application rate and biochar amendment on fruit yield and quality, photosynthetic carbon allocation, and soil carbon retention in apple orchards, a two-year field experiment was conducted using Malus domestica Borkh. cv. ‘Red Fuji’/M9T337. Six treatments were es...
