Nutrient saturation of crop monocultures and agroforestry indicated by nutrient response efficiency

Marcus Schmidt; Marife D. Corre; Bomin Kim; et al. Nutrient Cycling in Agroecosystems 2020. doi:10.1007/s10705-020-10113-6

Other claims from this paper (10)

Intervention effect Crop yield, plant-available nutrients and NRE were comparable between alley-cropping agroforestry and cropland monocultures.
Observation Trees in agroforestry had high nutrient response efficiency.
Association Trees in agroforestry contributed to nutrient retention of the agroforestry system as a whole.
Association The NRE of crops had a unimodal relationship with plant-available nutrients.
Observation NRE values of crops were beyond optimum in both agroforestry and monoculture, indicating nutrient saturation.
Intervention effect A 50% reduction of plant-available N would decrease crop yield by 17%.
Intervention effect A 50% reduction of plant-available N would increase N response efficiency by 67%.
Intervention effect A similar reduction of plant-available P would increase P response efficiency by 83%.
Recommendation Fertilizer inputs can be reduced or optimized without sacrificing crop yield or profit.
Association Optimized fertilization is expected to have beneficial effects on nutrient retention and redistribution.
