In the present study, a horizontal subsurface flow constructed wetland (HSF-CW) with a surface area of 240 m2 and HRT of 2 days, was used in the post treatment of a facultative aerated pond. Application rates of 175 kg BOD5 ha? 1 day? 1 and 408 kg COD ha? 1 day? 1 can be considered admissible for HSF-CW operation following a facultative aerated pond. The system presented values for COD, BOD5 and TSS removal of 88%, 98.8% and 99.3%, respectively. The system supported operation at a solids application rate of 23.3 g TSS m? 2 day? 1 for two years without clogging. The species grown in the CW (Brachiaria ruziziensis) presented a biomass produtivity of between 1.86 and 2.55 kg m? 2 y? 1 , providing CO2 biofixation of between 3.10 and 3.98 kg m? 2 y? 1 . The present study, conducted over two years, indicates that the HSF-CW model employed, and the operational parameters proposed, can be used in post treatment for a pond system that is not operating satisfactorily. |

The ?B? value, the 15N abundance of plants depending completely on biological nitrogen fixation (BNF) for growth, is required for quantifying BNF using the 15N natural abundance technique. This study aimed to investigate how common bean (Phaseolus vulgaris L.) cultivars with different growth patterns could affect the ?B? value calculated for the plant shoot. Two experiments were conducted in N-free solution. Experiment I had a factorial design with three cultivars and two rhizobium inoculants. Plants were harvested at pre-flowering stage. Experiment II was also factorial with two cultivars and two times of sampling: full flowering and mid-pod filling. Total N and δ15N analyses of different plant parts were carried out to estimate the ?B? value. There were differences between cultivars for N accumulation and 15N abundance, but no difference between rhizobium inoculants. Results revealed differences in ?B? value between cultivars of small and large seeds, the growth stage being also relevant. The ?B? values of −2.08 and −1.34? could be used for BNF estimates in small-seeded cultivars at full flowering and mid-pod filling stages, respectively, while such values should change, respectively, to −1.73 and −1.03? for large-seed cultivars. The mean ?B? value in shoots was −1.90 and −1.20? at full flowering and mid-pod filling stages, respectively. There are variations in ?B? value between cultivars of different cycle length and seed sizes, which are associated with plant architecture, thus a ?B? for each growth stage of common bean plants is required.
