Resumo: The aim of this study was to evaluate the efficiency of the porous ceramic cup extractors, associated with ion meters, for the determination of nutrients availability for bell pepper and melon crops in substrate. Substrate solution was acquired using aqueous extract 1:1.5 (v/v) and also the porous ceramic cup extractor. Electrical conductivity (EC), pH and macronutrient contents were determined for the substrate solution through analytical method. The concentrations of NO3- and K+ in the solutions obtained with porous ceramic cup extractors, and the N and K contents in the diagnostic leaf for nutritional evaluation were also determined. The concentrations of NO3- and K+ using the porous ceramic cup extractors have strong correlation (r=0.96 and 0.92, respectively) with the ones obtained using the standard method, as well as a moderate correlation (r=0.65) and a strong one (r=0.71) with contents of N and K, respectively, in the melon diagnostic leaf; and a weak correlation (r=0.36 and 0.26, respectively) in the bell pepper diagnostic leaf. The use of porous ceramic cup extractors for obtaining the substrate solution and the determination of the N-NO3- and K+ contents by means of specific ion meters are a fast method of evaluating nutrients availability in soilless cultures.

A solução de substrato foi obtida utilizando o extrator aquoso 1:1,5 (v/v) e o extrator de cápsula porosa. A condutividade elétrica (CE), o pH e a concentração dos macronutrientes na solução do substrato foram determinados por meio do método analítico. Além disso, foram determinadas as concentrações de NO3‑ e K+ nas soluções obtidas com os extratores de cápsula porosa, bem como as concentrações de N e K na folha diagnose do estado nutricional. As concentrações de NO3- e K+ obtidas por extratores de cápsula porosa apresentam forte correlação (r=0,96 e 0,92, respectivamente) com as obtidas pelo método padrão, bem como correlação moderada (r=0,65) e forte (r=0,71) com as concentrações de N e K, respectivamente, na folha diagnose do estado nutricional do melão e, correlação fraca (r=0,36 e 0,26, respectivamente) na folha diagnose do estado nutricional do pimentão. A utilização de extratores de cápsula porosa para a obtenção da solução do substrato e, a determinação das concentrações de N-NO3- e K+ por medidores de íons específicos, é um método rápido para avaliar a disponibilidade de nutrientes em cultivos sem solo.  Universidade Federal Rural do Semi-Árido2021-12-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1034710.1590/1983-21252022v35n112rcREVISTA CAATINGA; Vol. 35 No. 1 (2022); 117-126Revista Caatinga; v. 35 n. 1 (2022); 117-1261983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/10347/10823Copyright (c) 2021 Revista Caatingainfo:eu-repo/semantics/openAccessWamser, Anderson FernandoCecílio Filho, Arthur BernardesNascimento, Camila SenoNascimento, Carolina SenoCortez, Juan Waldir MendozaNowaki, Rodrigo Hiyoshi Dalmazzo2023-07-03T18:25:56Zoai:ojs.periodicos.ufersa.edu.br:article/10347Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:56.285260Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
