The study was developed in the Integrated Agroecological System area, in Seropédica (RJ, Brazil) between June  2011 and May  2012. The applied fertilizer formulations were: Formulation 1, 100% of nitrogen dose recommended for fig tree supplied by fertilizing with castor bean cake (CB); Formulation 2, 50% of nitrogen dose supplied by DFW application and 50% of nitrogen dose supplied by CB; Formulation 3, 75% of nitrogen dose supplied by DFW application and 25% of nitrogen dose from CB; Formulation 4, 100% of nitrogen dose supplied by DFW application.Data were submitted to analysis of variance and the averages were compared by Tukey’s test at 10% probability. The results demonstrated that branches length, number of leaves per branch, number of fruits, production and yield were lower in plants submitted to Formulation 4. Contamination of fruits by thermotolerant coliforms or Salmonellasp did not occur after DFW use as fertilizer. The results showed that the use of DFW in fig tree cultivation was sufficient to provide the nutritional needs of plants, as regards macronutrients and Fe.   Keywords: fertirrigation, environmental impact, final disposal of effluents and crop nutrition.     SILVA, J.B.

EFEITOS DO USO DE ÁGUA RESIDUÁRIA DE BOVINOCULTURANO CULTIVO DA FIGUEIRA (FICUS CARICA L.)         2 RESUMO   Objetivou-se com este trabalho avaliar os efeitos do uso da água residuária de bovinocultura de leite (ARB) no crescimento, produção, padrão fitossanitário dos frutos e na concentração de nutrientes nas folhas da figueira. As formulações de adubação aplicadas foram: Adubação 1 - 100% da dose de nitrogênio fornecida pela adubação com torta de mamona (TM); Adubação 2 - 50% da dose de nitrogênio comaplicação de ARB e 50% com TM; Adubação 3 - 75% da dose de nitrogênio com aplicação de ARB e os outros 25% da dose com TM; Adubação 4 - 100% da dose de nitrogênio com aplicação da ARB. Os resultados foram submetidos à análise de variância e as médias comparadas utilizando-se o Teste de Tukey a 10% de probabilidade. Diante dos resultados verificou-se que comprimento dos ramos, o número de folhas por ramos, o número de frutos, a produção e a produtividade foram menores nas plantas submetidas à Adubação4. Não ocorreu contaminação dos frutos por coliformes termotolerantes e Salmonella sp. Diante dos resultados concluiu-se que o uso de ARB no cultivo da figueira não proporciona deficiência nutricional às plantas no que se refere aos macronutrientes (N, Ca, Mg, K e P).   Palavras-chave: fertirrigação, impacto ambiental, disposição final de efluentes, nutrição vegetal.

We investigated the prevalence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli strains in dairy farm wastewater in Chiang Mai, Thailand. We analyzed wastewater samples collected from 150 dairy farms and found that 88.7% of the farms (n = 133) were positive for ESBL-producing E. coli. Multiplex polymerase chain reaction (PCR) amplification was performed to characterize the presence of bla CTX-M, bla TEM, and blaSHV in ESBL-producing isolates. blaCTX-M was found in all isolates (n = 133), followed by blaTEM (80/133, 60.2%), whereas blaSHV was not detected in any isolate. blaCTX-M and blaTEM were present in 60.2% (80/133) of the isolates, and 39.8% (53/133) isolates carried bla CTX-M alone. Subgroup analysis showed that CTX-M-1 was the most prevalent subgroup among the isolates (129/133, 97.0%), followed by CTX-M-8 (2/133, 1.5%) and CTX-M-9 (2/133, 1.5%). The distribution of the phylogenetic groups was as follows: group A (100/133, 75.2%), followed by B1 (14/133, 10.5%), D (6/133, 4.5%), F (6/133, 4.5%), B2 (4/133, 3.0%), and E (3/133, 2.3%). Based on enterobacterial repetitive intergenic consensus PCR (ERIC-PCR) and dendrogram analysis, 24 isolates were classified into clades I (n = 21), II (n =1), and III (n =2). Minor genetic differences were found in all clade I isolates. Our data suggest that the circulating of ESBL-producing E. coli carried at least one bla gene strain distributed in dairy farm wastewater in Chiang Mai.

Waste stabilisation ponds (WSPs) have been used for the treatment of dairy farm wastewater in New Zealand since the 1970s. The conventional two pond WSP systems provide efficient removal of wastewater BOD5 and total suspended solids, but effluent concentrations of other pollutants including nutrients and faecal bacteria are now considered unsuitable for discharge to waterways. Advanced Pond Systems (APS) provide a potential solution. A pilot dairy farm APS consisting of an Anaerobic pond (the first pond of the conventional WSP system) followed by three ponds: a High Rate Pond (HRP), an Algae Settling Pond (ASP) and a Maturation Pond (which all replace the conventional WSP system facultative pond) was evaluated over a two year period. Performance was compared to that of the existing conventional dairy farm WSP system. APS system effluent quality was considerably higher than that of the conventional WSP system with respective median effluent concentrations of BOD5: 34 and 108 g m-3, TSS: 64 and 220 g m-3, NH4-N: 8 and 29 g m-3, DRP: 13 and 17 g m-3, and E. coli: 146 and 16195 MPN/100 ml. APS systems show great promise for upgrading conventional dairy farm WSPs in New Zealand.
