Nutrient uptake of catch crops under non‐limiting growth conditions

Abstract Background Catch crops enhance nutrient cycling of cropping systems. Considering possible limitations catch crop studies in field and greenhouse experiments, a new approach was chosen to combine the advantages both systems quantifying potential for retention by crops. Aims This study aimed at identifying N, P, K uptake different species grown monoculture as mixture under non‐limiting growth conditions terms water availability. Methods were cultivated semi‐controlled large containers (August November 2020). Shoot uptake, leachate accumulation, soil N min , CAL‐P, CAL‐K (0–30 cm) quantified after harvest. After washing, root parameters with scanner. Results Nutrient highest phacelia. The seven performed equally well. closely related length surface area. Conclusions Under conditions, phacelia has conserve succeeding crop; however, low C : ratio frost‐sensitive could promote losses during winter. We conclude that growing single can be effective reducing leaching cultivating when nutrients are no growth‐limiting factors.
