“…The soil properties of the amended soils, including the pH value, conductivity, waterholding capacity, total organic carbon (TOC), total N, P and K and available N, P, K, Ca, Mg and Na, were measured before and after the planting experiment. The measurement method followed Pan et al [32,46]. They were determined according to methods of the American Society for Testing and Materials (ASTM) [47][48][49].…”

Sewage sludge (SL), Chinese medicinal herbal residues (CMHRs) and the raw materials of biochar (BC) are normally treated as wastes. However, SL, CMHRs and BC are potential candidates for soil amendments. The performances of soils amended with three different proportions (5%, 10% and 20% on a dry-weight basis) of SL-BC and SL-CMHR-BC in terms of ameliorating soil properties and attenuating antibiotics in soil–plant systems were investigated with two common crop species: carrot and lettuce. The amended soils in general showed higher nutrient levels than the control soils, and particularly for the 20% SL-CMHR-BC. The soils with 10% or 20% SL-BC or SL-CMHR-BC apparently retarded the germination performances of the two crop species, but the negative effects were not noticeable after a growing period. Six target antibiotics, amoxicillin (AMX), tetracycline (TC), sulfamethazine (SMX), norfloxacin (NOR), erythromycin (ERY) and chloramphenicol (CAP), were applied for growing the crops by using irrigation water with 3 μg L−1 (IW3) and 30 μg L−1 (IW30) of each antibiotic. The amended soils led to lower levels of antibiotics in the soils and crop tissues as compared with the control, with the 20% SL-CMHR-BC soils showing the most pronounced effect. The effects of the soil amendments on the bioconcentration factor (BCF) varied, but generally with lower values in the amended soils. Both SL-BC and SL-CMHR-BC were proven in the study as potential soil amendments for alleviating the environmental dispersal and human exposure risks of different antibiotics, and specifically 20% SL-CMHR-BC.

“…The promoting effect of N fertilization on plant growth at early growing stage weakened with decreasing N application rate. Such results showed that in soil with lower original N content, sufficient exogenous N application was able and also necessary to promote better growth performance at the early growth stage [56] because fertilization can reduce the negative influence of N deficiency stress on cucumber growth [57], whereas in soil with higher original residue N, exogenous N supply should be controlled for fear of the restrained plant growth associated with the physiological disorders in plants [58].…”

Cucumber plant growth and the fate of N in the plant-soil system are influenced by fertilization practices, the strengths of which may vary among soils. Three soils with different years of greenhouse vegetable cultivation (0, 2, and 18 years) were fertilized differently (CK, no N fertilizer applied; CF, chemical NPK fertilizers applied; RCF, reduced chemical NPK fertilizers applied, with N, P, and K reduced by 46.5%, 68.6%, and 54.7%; RCF+CM, 75% of the total N derived from chemical fertilizer and the rest from chicken manure in the case of reduced fertilization) in a pot experiment to study the changes in cucumber (Cucumis sativus L.) growth, N uptake, residue, and losses. The original N in soil was insufficient to maintain leaf growth and chlorophyll synthesis at later growth stages, even in soil with 18 years of greenhouse vegetable cultivation, where the original N content was the highest (total N 1.73 g kg−1). However, the CF treatment with excessive N fertilization inhibited leaf growth at the early growing stage and accelerated leaf senescence later, especially in soil with longer years of greenhouse vegetable cultivation. Therefore, reduced fertilizer application (RCF and RCF+CM) is appropriate to improve cucumber growth and productivity in greenhouse cultivation with different planting years. Although the same amount of N was applied, the RCF+CM treatment performed better than the RCF treatment in terms of increasing plant N uptake (by 30.5%) and soil N pool storage (by 25.0%) while decreasing N losses (by 16.6%) in soil with 0 years of greenhouse vegetable cultivation. In soil with 2 and 18 years of greenhouse vegetable cultivation, the soil itself functions much better in exogenous N retention and supply, with the N storage and losses not significantly different between the RCF and RCF+CM treatments. We conclude that reduced fertilization with the co-application of chicken manure is optimal for plant growth promotion, output-input ratio increase, soil N fertility improvement, and environmental risk mitigation.
