“…However, Santos et al (2005), in a study with sodic soil treated with 0 and 20 t ha -1 of organic material (urban garbage compound), did not observe a significant effect on EP of the herbaceous cotton cultivar CNPA-7H, indicating that the type of organic matter and/or genotypes from the same species may have different behaviors. mitigate the effects of salts, stimulating seed osmotic adjustment, or this agricultural input may favor the reallocation of reserves from the cotyledons to the other organs, reducing the adverse effects of salinity on the emergence of seedlings (CAMPOS et al, 2009 ns, **, and * indicate, respectively, non-significant, significant at p < 0.01, and p < 0.05;DFdegrees of freedom; CV -coefficient of variation.…”

“…Many studies have been conducted on minimizing the impacts caused by excesses of soluble salts and exchangeable sodium in the soil. Vital et al (2005), evaluating the application of four levels of gypsum (0, 50, 100, and 200% of the gypsum necessary) in a salinesodic soil, concluded that increasing gypsum lowered pH and ESP. Sousa et al (2012) stated that the application of calcium sulfate, elemental sulfur, or sulfuric acid followed by washing decreased the salinity and sodicity of a saline-sodic soil.…”

The prevailing climate of the semiarid region in the northeastern region of Brazil along with inadequate irrigation management, have caused the formation of halomorphic soils, which have hampered agricultural production and environmental sustainability of this region. Therefore, this study aimed to evaluate the emergence and initial growth of the cotton cultivar 'BRS Topázio' cultivated in soil with different levels of exchangeable sodium percentage (ESP) and concentrations of organic matter (OM) in a greenhouse from April to June 2014. The experiment was set in a randomized block design in a 5 × 4 factorial scheme, with three replicates, and the treatments consisted of five ESP levels (13.6, 22.4, 30.1, 39.0, and 48.0) and four OM concentrations (0, 5, 10, and 15% based on soil volume). Soils with an ESP ranging from 13.6 to 48.0 did not interfere with the emergence and number of leaves of cotton at 10 days after seeding (DAS). At 44 DAS, in the period preceding the flowering stage, ESPs ranging from 27 to 30 promoted greater plant height, stem diameter, and fresh and dry matter of shoot. Increasing OM increased the emergence percentage and emergence speed index and, at 44 DAS, increased plant height, stem diameter, and shoot fresh and dry matter. Increasing OM mitigated the effect of the exchangeable sodium up to an ESP of 30 on the number of leaves, plant height, stem diameter, and leaf area at 10 DAS, and up to mean ESPs of 28.5 and 34.0 for the number of leaves and leaf area, respectively, at 44 DAS. Key words: Gossypium hirsutum L. Sodicity. Cattle manure. ResumoAs condições de clima prevalecentes na região semiárida do nordeste Brasileiro, associado ao manejo inadequado da irrigação tem ocasionado a formação de solos halomórficos, promovendo assim, impactos negativos sobre a produção agrícola e a sustentabilidade ambiental desta região. Deste modo, objetivouse com este trabalho avaliar a emergência e o crescimento inicial do algodoeiro cv. BRS Topázio

“…A maior eficiência do composto à base de caulim, na última lavagem, deve-se provavelmente à sua baixa CTC em comparação com a vermiculita (Tabela 1), a qual poderia reter maior quantidade deste cátion no solo, diminuindo sua lixiviação (McBRIDE, 1995). Por outro lado, a elevação dos teores de sódio no lixiviado, pela aplicação do gesso é decorrente principalmente do deslocamento do sódio do complexo de troca pelo cálcio liberado pelo corretivo (VITAL et al, 2005). Neste processo, o sódio é deslocado para a solução do solo para reagir com os ânions sulfatos, formado sulfato de sódio o qual é removido após a aplicação de uma lâmina de água (SOUSA et al, 2012).…”

RESUMO:O presente trabalho teve objetivo de avaliar o efeito do gesso agrícola e doses de rejeitos de vermiculita e de caulim, sobre os atributos químicos de um solo salino-sódico e o crescimento do maracujazeiro amarelo. O experimento foi instalado num esquema fatorial 2 x 2 x 5, sendo dois tipos de compostos (composto de caulim e composto de vermiculita) presença e ausência de gesso agrícola e cinco doses de cada composto (0, 15, 30, 45 e 60% v/v) com três repetições, totalizando 60 vasos com capacidade para 9 L. O uso de compostos à base de rejeitos de caulim e de vermiculita, associados ou não ao gesso agrícola, contribui para diminuir a salinidade e a sodicidade do solo. A máxima produção de matéria seca do maracujazeiro foi obtida com a aplicação de 36,9 e 50,2% dos compostos à base de vermiculita e de caulim respectivamente, independentemente da aplicação de gesso agrícola.Palavras-chave: salinidade do solo, corretivos, gesso agrícola. Gypsum and rejects on the salinized soil and growth of yellow passion fruitABSTRACT: This study aimed to evaluate the effect of doses of gypsum and vermiculite tailings and kaolin on the chemical attributes of a saline-sodic soil and growing passion fruit. The experiment was arranged in a factorial 2 x 2 x 5, two types of compounds (compound composed of kaolin and vermiculite) presence and absence of gypsum and five doses of each compound (0, 15, 30, 45 and 60% v/v) with three replications, totaling 60 vessels with a capacity of 9L. The use of compounds based tailings kaolin and vermiculite, associated or not with gypsum, helping to reduce salinity and sodicity. The maximum dry matter production of passion fruit was obtained with the application of 36.9 and 50.2% of compounds based on vermiculite and kaolin respectively, regardless of the application of gypsum.

“…Porém, o período de chuvas nesta região é curto (quatro a cinco meses) e desuniforme, sendo necessária a irrigação (GHEYI et al, 1991;VITAL et al, 2005). Essa prática tem contribuído ao longo do tempo para a propagação de áreas com restrições ambientais tais como afetadas por sais ou da água de irrigação (SOUSA, 2007).…”
