“…Owing to the use of soil NR from the fertilizer applied in previous years, more nitrate-N remained in soil and even more NR at high N rates with increasing time. In the North China Plain, the SNR in the 0-90 cm soil layer was 41.5 and 131.5 kg N ha −1 y −1 under application of 400 and 550 kg N ha −1 , respectively (Hartmann et al, 2014).…”

Nitrogen Fertilization Strategies for Organic Wheat Production: Crop Yield and Nitrate Leaching

Nitrogen fertility management represents a crucial aspect for common wheat (Triticum aestivum L.) production, particularly when we deal with organic agriculture. Th is study was conducted to determine the eff ect of fi ve N fertilization strategies on yield, grain protein content, and N leaching risk. In a 3-yr fi eld experiment, a faba bean/wheat temporary intercropping (TIC) and four fertilization treatments with extra-farm N sources were compared. Extra-farm N sources were represented by blood meal (BM) and roasted leather (RL) (broadcast all-at-once at seeding or split into one-half at seeding and one-half at tillering in a side-dressing application). Unfertilized and mineral fertilized controls were included. Th e eff ect of the legume on TIC wheat N uptake was always positive while dry weight accumulation and yield were generally poorly aff ected. Regardless of the broadcasting method, BM treatments generally showed a slightly higher yield and grain protein content compared to wheat fertilized with roasted leather (this was also confi rmed by fertilizer release effi ciency). Th e risk of N leaching was maximum at the onset of drainage (i.e., during the fi rst phase of crop growth), so using organic fertilizers at preseeding stage appeared to be a very risky practice, especially if quick-N-releasing ones are used. Splitting the organic fertilizer rate avoided a large amount of mineralized N to be leached in the watershed during the critical stage of drainage onset. Th e TIC was the best option in terms of environmental preservation, and assured a constantly higher grain protein content compared to the other organic fertilization treatments.
