Evaluating soil nitrate dynamics in an intercropping dripped ecosystem using HYDRUS-2D

The competition mechanisms between crop species for water and nutrients, especially nitrate (NO3-N), in intercropping ecosystems are still poorly understood. Therefore, an experiment involving high (300 kg ha−1 for corn and 250 kg ha−1 for tomato), medium (210 kg ha−1 for corn and 175 kg ha−1 for tomato), and low (150 kg ha−1 for corn and 125 kg ha−1 for tomato) N-fertilizer applications (HF, MF, LF, respectively) was conducted in the corn and...
