Resumo: | Soils of arid and semi-arid regions may present salt accumulation damaging to plant growth, due to either natural salinization processes or human contribution by inadequate irrigation management. At the Brazilian Northeast, climactic conditions are favorable to salt accumulation in soil. The Assu/Mossoró agricultural production center, in this region, has shown high productive potential for irrigated fruit production for exportation, but the irrigation waters may have high salt content. Without an adequate water quality control, increasing salt accumulation may happen, which could lead to soil degradation by salinization. This work aims to evaluate Assu/Mossoró, RN, agricultural production center soil degradation under irrigation with increasing electrical conductivity (CE) levels, and sodium adsorption rates (SAR), when cultivated with cantaloupe. The work was conducted in a greenhouse at the Environmental Sciences Department of Semi-Arid Rural Federal University. Four soil types, traditionally used for cantaloupe production, were used and irrigated with solutions corresponding to eight CE (CE = 100, 250, 500, 750, 1250, 1750, 2250 and 3000 μS/cm) and two SAR (SAR = 4 and 12) levels, as salinity treatments, corresponding to the irrigation waters used in the Northeast, with low sodification risk, especially in the studied area. So the experiment was a factorial arrangement of 4 x 8 x 2 (four soils, eight CE and two SAR), with three replicates, and 192 experimental units, on a randomized block design. Plant (fresh and dry matter production, and nutritional composition) and soil (CE, saturation extract pH, soluble elements, exchangeable cations, cation exchange capacity, and clay mineralogical composition) variables were evaluated. Fresh and dry cantaloupe production wasreduced with increased water salinity in two succeeding crops, leading to plant death a few days after transplanting in the second cycle. Increased water salinity enhanced Ca, Mg, Na, K and Cl plant accumulation, as well as soil pH, CE, and soluble and exchangeable Ca, Mg, Na and K contents. Saline water use increased salinity andsodicity of the four studied soils, diminishing cantaloupe growth. |

No Nordeste do Brasil, as condições climáticas são propícias ao acúmulo de sais no solo. Neste contexto, o Agropolo Assu/Mossoró tem representado forte potencial produtivo na fruticultura irrigada para exportação, entretanto, as águas usadas podem apresentar elevados teores de sais. Sem um efetivo controle da qualidade destas águas, pode estar ocorrendo um progressivo acúmulo de sais nos solos que levariam à degradação dessas áreas por salinização. Por isso, esse trabalho, objetivou avaliar a degradação de solos do Agropolo Assu/Mossoró, RN, irrigados com águas de níveis crescentes de condutividade elétrica (CE) e relação de adsorção de sódio (RAS) cultivados com melão. O trabalho foi conduzido em casa de vegetação no Departamento de Ciências Ambientais da Universidade Federal Rural do Semi-Árido. Foram utilizados 4 tipos de solos da região tradicionalmente cultivados com melão, irrigados com soluções preparadas para corresponderem a oito valores de condutividade elétrica (CE = 100, 250, 500, 750, 1250, 1750, 2250 e 3000 μS/cm), e dois de relação de absorção de sódio (RAS = 4 e 12), combinados como tratamentos de salinidade, correspondendo também à maioria das águas de irrigação usadas no Nordeste, com baixo risco de sodificação, especialmente para a região em estudo. Assim, o experimento foi num arranjo fatorial 4 x 8 x 2 (quatro solos, oito CE e duas RAS), em três repetições, contabilizando 192 unidades experimentais. O delineamento experimental foi em blocos casualizados, com uma repetição por bloco. Foram avaliadas variáveis de planta (produção de matéria fresca e seca da parte aérea, e composição nutricional das mesmas), de solo (CE,pH do extrato de saturação, elementos solúveis, cátions trocáveis, capacidade de troca de cátions) e composição química do lixiviado. A produção de matéria fresca e seca de melão foi reduzida com o aumento da salinidade da água nos dois cultivos sucessivos, causando morte das plantas no segundo cultivo poucos dias após o transplantio. O incremento da salinidade da água promoveu elevação nos conteúdos acumulados de Ca2+, Mg2+, Na+, K+ e Cl- nas planta de melão, aumentando também o pH, a CE, os teores de Ca, Mg, Na e K solúveis e trocáveis, bem como a RAS e a PST dos solos. O uso de águas salinas promoveu aumento na salinidade e sodicidade dos quatro solos estudados, dificultando o crescimento das plantas de melão.Submitted by (lucia.rodrigues@ufrpe.br) on 2016-08-11T12:53:48Z No. of bitstreams: 1 Michelangelo de Oliveira Silva.pdf: 748092 bytes, checksum: 2728461bae9fb5dfff8d5a7326c0aa0c (MD5)Made available in DSpace on 2016-08-11T12:53:48Z (GMT).
