“…Farinelli & Lemos (2012), studying the effects of topdressing N fertilization on the triple hybrid corn cultivar DKB 466, obtained a mean N concentration of 28.33 g kg -1 under fertilization with 120 kg ha -1 of urea. Prior et al (2015), studying the effects of the association between swine wastewater and mineral fertilization on the corn crop and on the soil, obtained leaf N concentration of 22.66 g kg -1 under fertigation with 450 m 3 ha -1 of wastewater.…”

This study aimed to evaluate the contents of macronutrients (NPK and S) and the growth of ‘Potiguar’ corn fertigated with human urine, cassava wastewater and their associations with NPK. The experiment was set up in greenhouse located on Campus I of Universidade Federal de Campina Grande. A completely randomized experimental design was used, consisting of eight treatments, corresponding to fertigation with mineral fertilizer NPK formula; organic, composed of yellow water, cassava wastewater and human urine associated with cassava wastewater; organomineral, composed of human urine associated with phosphorus and potassium, cassava wastewater associated with nitrogen and phosphorus and human urine associated with cassava wastewater and phosphorus, with five repetitions. At 50 days after sowing (DAS), plants were evaluated for the leaf NPK and S concentrations and growth variables: number of leaves, plant height, stem diameter, leaf area, fresh and dry mass of leaves, mass of stem and shoots. Nitrogen and phosphorus concentrations and the growth variables number of leaves, plant height, fresh and dry mass of leaves, mass of stem and of shoot were influenced by fertigation with human urine, cassava wastewater concentrations and their associations with NPK. In the leaves of corn cultivar Potiguar the accumulated concentrations of N, P and K, at 50 DAS, varied in the sequence N > K > P. Human urine has potential as source of N in fertigation of corn and cassava wastewater can be used if associated with other sources of nutrients.

“…However, grain yield was influenced by SW doses because, in the treatment with highest dose of SW (T2), grain yield was 9.2% higher than that of the control treatment. This increment could be greater because Prior et al (2015) reported increase of up to 23% in yield with SW application associated with chemical fertilization (CF).…”

A B S T R A C TThis study aimed to evaluate soybean and corn yields and soil physical attributes of a Dystrophic Red Latosol fertilized with swine wastewater (SW). Therefore, a field experiment was conducted in randomized blocks to evaluate five treatments of fertilization in the 2014/2015 season (soybean in the summer and corn in the second season). The treatments were: T1 -control (fertilized exclusively with chemical fertilizers); T2 -fertilized with 1270 m 3 ha -1 of SW; T3 -fertilized with 170 m 3 ha -1 of SW; T4 -fertilized with 50 m 3 ha -1 of SW; and T5 -fertilized with 50 m 3 ha -1 of SW + chemical fertilization. Soil samplings and soil physical analyses were performed before soybean cultivation and after corn harvest. No significant alteration was observed in soil physical attributes during the evaluation period. The application of swine wastewater in the fertilization of soybean and corn, cultivated in Dystrophic Red Latosol with high clay contents, positively affected these crops, since it led to good yields in soybean (with an average of 2990.85 kg ha -1 ) and increased corn yields (with a maximum of 7126.5 kg ha -1 ). In addition, soil physical properties were not altered.Atributos físicos do solo e produtividades de soja e milho cultivadas com água residuária R E S U M O Objetivou-se avaliar as produtividades de soja, milho e os atributos físicos de um Latossolo Vermelho Distroférrico fertilizado com água residuária de suinocultura (ARS). Para isso, foi realizado um experimento a campo utilizando o delineamento em blocos casualizados. Foram avaliados cinco tratamentos de adubação na safra 2014/2015 (soja no verão e milho segunda safra). Os tratamentos foram: T1 -Controle (fertilizado exclusivamente com adubação química); T2 -Fertilizado com 1270 m 3 ha -1 de ARS; T3 -fertilizado com 170 m 3 ha -1 de ARS; T4 -Fertilizado com 50 m 3 ha -1 de ARS; e, T5 -Fertilizado com 50 m 3 ha -1 de ARS mais adubação química. Amostragens e análises físicas de solo foram realizadas antes do cultivo da soja e após a colheita do milho. Em relação aos atributos físicos do solo, não houve alterações significativas durante o período avaliado. A aplicação de água residuária de suinocultura na fertilização dos cultivos de soja e milho, cultivadas num solo Latossolo Vermelho Distroférrico com alto teor de argila, influenciaram positivamente esses cultivos, uma vez que proporcionou boas produtividades para soja (com média de 2990,85 kg ha -1 ) e incremento de produtividade para o milho (com máxima de 7126,5 kg ha -1 ). Além disso, os atributos físicos do solo não foram alterados.

“…Even many positives aspects related to SWW addition in soil are reported, its successive use can cause soil contamination because SWW carries large amounts of not balanced nutrients (Prior et al, 2015), resulting in high concentration as time passes.…”

Swine wastewater (SWW) is a residue from pig farming that presents a high load of nutrients and organic matter. The appliance of organic matter in soil alters the microbial dynamic and may suppress soilborn phytopathogens. This study aimed at evaluating the inhibition on mycelial growth of Sclerotinia sclerotiorum and Sclerotium rolfsii in vitro under SWW doses. Hereupon, three kilograms of a soil classified as red dystroferric latosol was collected and sieved. Half of it was autoclaved. SWW was incorporated at doses of 0 mL, 2.5 mL, 5 mL, 10 mL and 20 mL in both soil conditions, autoclaved and not autoclaved. Afterwards, 130 grams of each soil was separately put into Petri plates above what a thin layer (≅ 5 mL) of Water-Agar (2%) medium was carefully spread over. Above this agar layer, one disk (6 mm diameter) of pure mycelium from each fungal grown in Potato Dextrose Agar medium was individually placed on the center of each plate. Daily evaluations on mycelial growth measuring were taken and ended when mycelium in control plates (without SWW addition) reached plate borders. Results indicated that in autoclaved soil condition, the inhibition was proportional to the dose, what is to say that the higher the dose the less the mycelial growth. In not autoclaved soil there was no significant difference among treatments, suggesting stimuli on suppression effect for both pathogens caused by SWW. In addition, the confirmed potential of SWW as a suppressor of S. sclerotiorum and S. rolfsii leads to promising investigations on other phytopathogens hard to control.
