“…Thus, yearly applications may not be needed and the subsequent application rates can be considerably reduced Correa-Victoria et al 2001 ). For example, Si applications in a rice-sugarcane ( Saccharum offi cinarum ) rotation in southern Florida resulted in increased yields of both rice and sugarcane that was grown immediately after rice (Alvarez and Datnoff 2001b ). Correa-Victoria et al ( 2001 ) also reported that the application of slag in Colombia increased upland rice yield by 100 % due to its residual effect.…”

“…It has been well documented that Si nutrition has a defi nite agronomic role in sugarcane crop cultivation, especially on highly weathered tropical soils such as oxisols, ultisols, entisols and histosols (organic soils) (for review, see Savant et al 1999 ;Meyer and Keeping 2001 ). Earlier fi eld trials conducted in Hawaii, Mauritius, Puerto Rico, Florida, South Africa, Brazil and Australia demonstrated that the use of silicate slag as a source of Si for sugarcane increased yield by 10-50 % on Si-low soils (Ayres 1966 ;Clements 1965 ;Fox et al 1967 ;Samuels 1969 ;Cheong and Halais 1970 ;Haysom and Chapman 1975 ;Gascho 1976 ;Elawad et al 1982 ;Anderson et al 1991 ;Alvarez and Datnoff 2001b ;Meyer and Keeping 2001 ;Berthelsen et al 2001 ). Similar results were obtained in Asia including China, Chinese Taiwan, Indonesia, Malaysia and Pakistan (Savant et al 1999 and the references therein; Wang et al 2001 ;Ashraf et al 2009 ).…”

Silicon (Si) has widely been reported to increase the growth and biomass, yield and quality of a broad range of crops including monocotyledonous crops such as rice, wheat, maize, barley, millet, sorghum and sugarcane that actively take up and accumulate high amounts of Si in their organs and some dicotyledonous crops such as cotton and some vegetable and fruit crops. The yield increment, however, may be attributable not only to the benefi cial effects of Si including growth promotion, lodging resistance and biotic and abiotic stress resistance but also to some indirect effects such as pH adjustment and acquisition of macro-and micronutrients contained in the silicate fertilizers, especially when slags or Si-containing mineral ores are used as sources of silicate fertilizer.

“…As a consequence, these materials might be more attractive to the producer for field use. CSS also has the advantage of a proven track record in slag fertilisation of rice and sugar cane crops 16, 19, 31. The effects of CSS are still biologically significant; doubling of silica reduced severe rabbit feeding damage by 50% (see Section 3.1).…”

“…The use of CSS is particularly promising as it is cheaper than calcium silicate and has a proven track record in slag fertilisation of rice and sugar cane crops 16, 19, 31. Although the majority of research on silicon fertilisation concentrates on rice and sugar cane crops, there have been some other reported benefits in wheat.…”

Boosting silica levels in wheat leaves reduces grazing by rabbits

Systemic application of sodium silicate can significantly enhance the levels of leaf silica in winter wheat (Triticum aestivum L. cv. Mercia), suggesting that this material could reduce the palatability of plants to vertebrate herbivores (e.g. rabbits, Oryctolagus cuniculus L.). A bioassay was developed using hydroponically grown wheat plants. Plants treated with sodium silicate were significantly more resistant to grazing by wild rabbits than untreated plants, with severe, potentially lethal feeding damage being reduced by over 50%. Further studies were carried out to develop more practical techniques for boosting silica levels in plants using silicon-rich 'fertilisers' including calcium silicate and calcium silicate slag (CSS). Silica levels were elevated in the plant 1.9-2.8 times over the control through the application of various silicon materials, in line with those of the hydroponic treatment. Encouragingly, levels of silica were elevated even in young wheat plants, which are most vulnerable to rabbit damage, and in a range of wheat varieties. The use of CSS is particularly promising because of its lower cost in comparison with calcium silicate, and it has a proven track record in slag fertilisation of rice and sugar cane crops. At the optimum CSS application rate of 3 g silicon L(-1) soil, wheat silica levels were approximately doubled, with no detrimental impacts on long-term growth or yield.

“…Its application is easier and cheaper. Furthermore, it is better soluble in water and it is deposited on the leaf surface where it is absorbed in a similar way as by the roots (Alvarez & Datnoff, 2001). Silicon, after being absorbed by the plant, polymerises and accumulates in the cell wall of the epidermis (Jarvis, 1987) and support tissue, strengthening significantly the structure of the plant (Plucknett, 1971) and generally influences positively the growth and development of the plant (Ma et al, 2001).…”

Effect of silicon application to Eucalyptus camaldulensis on the population of Glycaspis brimblecombei (Hemiptera: Aphalaridae)

The use of silicon in forestry has increased recently as it is directly related to improved resistance to insect pests. The red gum lerp psyllid, Glycaspis brimblecombei, occurs in all eucalypt producing regions in Brazil. Two field experiments were conducted to study the effect of silicon applied to Eucalyptus camaldulensis on the psyllid population. In the first experiment, the applications were made via soil (calcium silicate) and leaves (potassium silicate) in a nine months old E. camaldulensis plantation. In the second experiment, we evaluated silicon on seedlings, incorporating it into the substrate (soil) or applying it on leaves (foliar). Monthly, for 24 months, the number of psyllid eggs and immatures were counted on leaf samples. The plant height was measured at 9, 12, 16 and 24 months (experiment 1) and at 4, 8, 12 and 24 months (experiment 2) after application. The numbers of eggs and immatures were lower in periods of higher precipitation, indicating less psyllid attack during the rainy season. The psyllid population was lower in treatments with application of silicon both foliar and via soil compared to control. No significant differences were found in the height of E. camaldulensis plants. Efeito da aplicação de silício em Eucalyptus camaldulensis em população de Glycaspis brimblecombei (Hemiptera: Aphalaridae) Resumo-O uso do silício na área florestal tem aumentado recentemente, pois o elemento está relacionado a uma melhoria na resistência a insetos pragas. O psilídeo de concha, Glycaspis brimblecombei é encontrado em todas as regiões produtoras de eucalipto no Brasil. O efeito do silício aplicado em Eucalyptus camaldulensis, na população do psilídeo, foi estudado em dois ensaios. No primeiro experimento, as aplicações foram via solo (silicato de cálcio) e foliar (silicato de potássio) em uma plantação de nove meses. No segundo experimento, este mineral foi aplicado em mudas de eucalipto, no substrato ou sobre as folhas. Mensalmente, durante 24 meses, ovos e imaturos de G. brimblecombei foram amostrados nas folhas. A altura das plantas foi medida com 9, 12, 16 e 24 meses (experimento 1) e, aos 4, 8, 12 e 24 meses (experimento 2) após a aplicação dos tratamentos. O número de ovos e de imaturos foram menores nos períodos de maior precipitação, indicando menos ataque dos psilídeos durante a estação chuvosa. A população psilídeo foi menor nos tratamentos com aplicação de silício tanto foliar como via solo. Nenhuma diferença significativa foi encontrada na altura de plantas de E. camaldulensis.
