“…In the third growing cycle there is once again a linear fit for the data obtained with increases of 2.39 and 5.38 mg L -1 for each unit increase in the nitrogen doses applied for the depths of 0.4 m ( Figure 4E) and 0.6 m ( Figure 4F), respectively. The results obtained corroborate those of Coelho, Andrade Neto and Barros (2014), who observed an increasing NO 3-concentration in the soil solution with the increase in the nitrogen fertilizer dose applied via fertigation in the banana crop.…”

“…These results reinforce the influence of nitrogen fertilizers on the soil solution, as observed by Coelho, Andrade Neto and Barros (2014) and Souza et al (2012). According to the analysis of dispersion of data on electrical conductivity in the soil solution (Figure 7), the best fit model was the linear one for all growing cycles and depths studied.…”

“…In the semiarid region of Brazil, with the advent of irrigation in fruit farming, using these systems in fertigation is a major means for incorporating nutrients in the soil, having as advantage reduced workforce, flexibility in application and the efficiency of its use (Cunha et al, 2014). The efficiency of fertigation involves the assessment of the irrigation system in relation to its water application efficiency and uniformity (Cunha et al, 2014), and the monitoring of the application of fertilizers; additionally, one should know the concentration of the latter from the injection moment Andrade Neto;Barros, 2014;Nesthed et al, 2013), until the condition of the nutrients SILVA, A. O. da et al in the soil , which can be done through the monitoring of the soil solution via porous cup extractors .…”

In the semiarid region of Brazil the use of irrigation systems for applying fertilizers in horticulture is the primary means for incorporating nutrients in the soil. However, this technique still requires its use in wine vines to be assessed. In view of this, this study aimed to assess nitrate and potassium concentrations in soil fertigated with nitrogen and potassium fertilizers in 3 wine grape growing cycles. A field experiment was conducted with 'Syrah' wine grapes, in Petrolina, Pernambuco, Brazil; it assessed five nitrogen doses (0, 15, 30, 60 and 120 kg ha -1 ) and five K 2 O doses (0, 15, 30, 60 and 120 kg ha -1 ) applied by drip irrigation system with two emitters per plant, with a flow rate of 4 L h -1 . The experimental design used was the factorial split-plot, making up 13 combinations arranged in 4 randomized blocks. Soil solution samples were collected weekly with the aid of porous cup extractors for all treatments and at depths of 0.4 and 0.6 m by determining nitrate and potassium concentrations and electrical conductivity. Increased levels of both nutrients in the irrigation water increased the availability of nitrate and potassium in the soil solution. The highest nitrate and potassium concentrations were found in the second growing cycle at both depths studied.Index terms: Vitis vinifera L.; soil solution; fertigation. RESUMONo Semiárido do Brasil com o advento da irrigação na fruticultura, o aproveitamento destes sistemas para o uso da fertirrigação é um dos principais meios para a incorporação de nutrientes no solo. Porém, esta técnica ainda requer avaliações sobre seu uso, manejo e sistemas de aplicação. Diante disto, esse trabalho teve como objetivo avaliar a concentração de nitrato e potássio em solo fertirrigado com fertilizantes nitrogenados e potássicos em cultivo de videira de vinho. Foi realizado um experimento de campo com videiras 'Syrah', em Petrolina-PE, sendo avaliados cinco doses de nitrogênio (0, 15, 30, 60 e 120 kg ha -1 ) e cinco doses de K 2 O (0, 15, 30, 60 e 120 kg ha -1 ), em esquema fatorial fracionado, perfazendo 13 combinações, dispostas no delineamento blocos casualizados com quatro repetições, aplicadas via fertirrigação. A irrigação foi realizada por gotejamento com dois emissores por planta com vazão de 4 L h -1 . Amostras de solução do solo foram coletas semanalmente em todos os tratamentos nas profundidades de 0,4 e 0,6 m, determinando-se a concentração de nitrato, de potássio e a condutividade elétrica. Os resultados permitiram concluir que o aumento da concentração de nitrogênio e potássio na água de irrigação aumentou a disponibilidade de nitrato e potássio na solução do solo. As maiores concentrações de nitrato e potássio foram observadas no segundo ciclo de produção da cultura da videira em ambas as profundidades estudadas.Termos para indexação: Vitis vinifera L.; solução do solo; fertirrigação.

“…Nitrate and potassium concentrations in the injection solution were 3, 10 and 15 g L -1 . These concentrations were defined on previous experiments (COELHO et al, 2014). Fertigation frequencies were 3 and 7 days, values recommended for the banana crop.…”

“…High concentrations at the emitter outlet can cause clogging, especially in periods of interruption of irrigation, which favor the deposition of salts in the emitters. High concentrations of fertilizer may also cause increase in the soil solution electrical conductivity in short periods of time (COELHO et al, 2014). Franco et al (2017) point out that further studies are needed for the dissemination of this method in the management of fertigation, with emphasis mainly on the nutritional status of plants.…”

Fertirrigation allows total control of the amount of applied fertilizers to the soil as a function of crop demand. Fertigation relies on monitoring of soil ions to obtain the sustainability of soil chemical conditions. The continuous evaluation of ions in the soil solution also contributes to the estimation of the cycling rate of chemical elements and nutrient leaching in the field. The objective of this work was (i) to evaluate nitrate, potassium, sodium and electrical conductivity in the soil solution submitted to different concentrations of injection solution and fertigation frequency during one cycle of the "Grande Naine" banana in a non-cohesive Yellow Latosol and (ii) to evaluate the effects of concentration and fertigation frequency on yields of banana crop. The experiment was carried out according to a randomized block design with six treatments and four replications in a 3 x 2 factorial scheme with three concentrations of the injection solution (3, 10 and 15 g L-1) x two fertigation frequencies (3 and 7 days). The treatments influenced the values of the ion concentration in the soil solution in the soil profile corresponding to the depths of 0-0.30 e 0.30-0.60 m. The concentration of the injection solution and the interaction frequency x concentration influenced the electrical conductivity and nitrate concentration of the soil solution. There was no significant effect of the injection solution and fertigation frequency on production variables.
