“…It has a positive effect on the growth of crops such as tomato (Peaslee and Frink, 1969), barley, and soybean (Hodson and Evans, 1995;Nolla et al, 2006), and many others (Liang et al, 2007;Nolla et al, 2012). The application of Si may reduce the severity of fungal diseases such as blast and sheath blight of rice (Farnaz et al, 2012); powdery mildew of barley, wheat, cucumber, muskmelon, and grape leaves; and vermin damage of rice by plant hopper (Crooks and Prentice, 2012;Ma et al, 2001;Menzies et al, 1992;Datnoff et al, 2001).…”

Abstract. In response to human population increase, the utilization of acid sulfate soils for rice cultivation is one option for increasing production. The main problems associated with such soils are their low pH values and their associated high content of exchangeable Al, which could be detrimental to crop growth. The application of soil amendments is one approach for mitigating this problem, and calcium silicate is an alternative soil amendment that could be used. Therefore, the main objective of this study was to ameliorate soil acidity in rice-cropped soil. The secondary objective was to study the effects of calcium silicate amendment on soil acidity, exchangeable Al, exchangeable Ca, and Si content. The soil was treated with 0, 1, 2, and 3 Mg ha −1 of calcium silicate under submerged conditions and the soil treatments were sampled every 30 days throughout an incubation period of 120 days. Application of calcium silicate induced a positive effect on soil pH and exchangeable Al; soil pH increased from 2.9 (initial) to 3.5, while exchangeable Al was reduced from 4.26 (initial) to 0.82 cmol c kg −1 . Furthermore, the exchangeable Ca and Si contents increased from 1.68 (initial) to 4.94 cmol c kg −1 and from 21.21 (initial) to 81.71 mg kg −1 , respectively. Therefore, it was noted that calcium silicate was effective at alleviating Al toxicity in acid sulfate, rice-cropped soil, yielding values below the critical level of 2 cmol c kg −1 . In addition, application of calcium silicate showed an ameliorative effect as it increased soil pH and supplied substantial amounts of Ca and Si.

“…Since then, research has extended to other grasses and grains such as barley (Hordeum vulgare L.; 7), corn (Zea mays L.; 8), oats (Avena sativa L.; 9), pasture (10) and turf grasses (11); sugarcane (Saccharum officinarum L.; 12), and wheat (Triticum aestivum L.; 13), and to dicotyledonous crops such as cucumber (Cucumis sativus L.; 14), grapes (Vitis vinifera L.; 15), pepper (Capsicum L.; 16), pumpkin (Cucurbita pepo L.; 17), soybean (Glycine max (L.) Merr. ; 18), and tomato (Solanum lycopersicum L.; 19). Beneficial effects from Si fertility have included increased stress tolerance (disease, insect, drought, salt, nutrient imbalance, low and high temperature) and yield increases with or without stress (20).…”

A 5-day method for determining the soluble silicon (Si) concentrations in nonliquid fertilizer products was developed using a sodium carbonate (Na2CO3)-ammonium nitrate (NH4NO3) extractant followed by visible spectroscopy with heteropoly blue analysis at 660 nm. The 5-Day Na2CO3-NH4NO3 Soluble Si Extraction Method can be applied to quantify the plant-available Si in solid fertilizer products at levels ranging from 0.2 to 8.4% Si with an LOD of 0.06%, and LOQ of 0.20%. This Si extraction method for fertilizers correlates well with plant uptake of Si (r2 = 0.96 for a range of solid fertilizers) and is applicable to solid Si fertilizer products including blended products and beneficial substances. Fertilizer materials can be processed as received using commercially available laboratory chemicals and materials at ambient laboratory temperatures. The single-laboratory validation of the 5-Day Na2CO3-NH4NO3 Soluble Si Extraction Method has been approved by The Association of American Plant Food Control Officials for testing nonliquid Si fertilizer products.

“…Crê-se, também, que o transporte do Si se dê principalmente através do movimento ascendente da água no interior da planta Ramos et al, 2008). Depois de absorvido o ácido monossolícico é depositado especialmente nas paredes das células da epiderme contribuindo substancialmente para fortalecer a estrutura da planta e aumentar a resistência ao acamamento e ao ataque de pragas e doenças (Nolla et al, 2006).…”

A adubação com silício pode aumentar a produtividade pelo aumento da resistência ao acamamento, ao estresse hídrico e a desidratação após a colheita. O objetivo deste trabalho foi avaliar a produtividade e a qualidade pós-colheita de Helicônia Golden Torch sob fontes e doses de silício. O delineamento experimental foi em blocos inteiramente casualizados em um esquema fatorial 3 x 4 utilizando-se três fontes de silício e quatro doses de Si. Avaliaram-se as seguintes variáveis: número de perfilhos, início de floração, comprimento da haste floral, diâmetro da haste floral, comprimento da bráctea, número de hastes florais, teor de silício nas folhas e queima da bráctea aos 5, 10 e 15 dias após a colheita. Os resultados obtidos demonstraram que a aplicação da fonte silicato de sódio foi a que melhor influenciou o crescimento da Helicônia Golden Torch. As maiores doses de silicato de sódio que influenciaram o comprimento da haste floral, o diâmetro da haste floral e o número de hastes florais foram 576, 400 e 560 mg dm . O teor de silício na folha aumentou com a aplicação de doses crescentes de silicato de cálcio. Productivity and postharvest quality of Heliconia Golden Torch under different sources and doses of silicon A B S T R A C TThe silicon fertilization can increase productivity by increasing resistance to lodgaing, to water stress and dehydration after harvest. The objective of this study was to evaluate productivity and postharvest quality of Heliconia Golden Torch under doses and sources of silicon. The experiment was conducted in randomized design in factorial 3 x 4 with four replications, utilizing three sources and four doses of silicon. The following variables were evaluated: number of tillers, the beginning of the flowering, length of flower stem, diameter of flower stem, length of bract, number of flower stem, silicon content in leaves and burning of bracts on the 5 th , 10 th and 15 th day postharvest. The results showed that the application of sodium silicate was better to influence the growth of Heliconia Golden Torch. The higher doses of sodium silicate which influenced the length of flower stem, diameter of flower stem, length of bract and the number of the flower stem were 576, 400 and 560 mg dm -3 . The burning of bract was less when sodium silicate was applied at dose of 550 mg dm -3 . Content of silicon in the leaf increased with increasing doses of application of calcium silicate. IntroduçãoA produção de flores tropicais de corte é uma atividade que vem ganhando destaque no "agrobusiness", tornandose alternativa de investimento tanto para produtores que se utilizam de altas tecnologias como extrativistas da região amazônica que trabalham com a exploração sustentável da floresta. Para sua consolidação e expansão, o setor manifesta a crescente urgência de ações articuladas aos diferentes segmentos que fazem parte da cadeia produtiva destacando-se a necessidade da redução dos custos com insumos como os fertilizantes minerais, indispensáveis no processo produtivo e que, anualmente, representam u...
