“…It is shown by a long-term trial conducted at Rothamsted Experimental Station that the annual straw exports from wheat fields reduce the amount of phytolith input to the soil, which decreases the bio-available Si in soils. A significant correlation between Si concentration in straw and yield is also shown 7 . In a long-term trial with rice conducted at four experimental stations located in northern Japan, it was shown that the plant-available Si in the surface soil with continuous rice straw application was 1.25 times higher than without the application 10 .…”

We conducted a 12-year field experiment to study the combined effects of rice straw compost and chemical fertilizer application on a double rice cropping system in the Mekong Delta, Vietnam and established 7 treatments using a randomized block design with 3 replications. We calculated the yields of treatments relative to those of conventionally fertilized plots (i.e. with no added rice straw compost), and analyzed their annual trends. In the plots with rice straw compost, we observed a positive trend over 12 continuous wet cropping seasons. In comparison with conventional fertilization, the application of rice straw compost with reduced chemical fertilizer can maintain rice productivity over a longer period. We analyzed the nutrient status of the rice straw at harvest over 4 cropping seasons and observed that the Si concentration of the rice straw in conventionally fertilized plots was significantly lower than that in the plots where rice straw compost was applied. The N, P and Mg concentrations of the rice straw increased with the fertilizer application rate, while the concentrations of K, Ca, Mn, Fe, Zn, and Cu did not differ significantly among treatments. Our results suggest that continuous removal of rice straw may reduce the Si availability in soil, thereby decreasing rice productivity. In addition, we verified that rice straw compost can be an effective source of silicon for paddy rice.

“…In soil, Si compounds mainly present as SiO 2 , about 50-70 % of the soil mass, and in various aluminosilicate forms (Sommer et al, 2006). Although Si is abundant in soil, but most of its sources are not available for plant uptake due to low solubility of Si compounds in soil (Guntzer et al, 2012;Rizwan et al, 2012;Peera et al, 2016).…”

AbstrakSilika (Si) AbstractSilicon (Si) is the second most abundant in the soil varies from 50 to 400 g Si per kg of soil. Silicon has positive influence on the plant resistance to various abiotic and biotic stressors such as salinity, drought, heavy metal toxicities and diseases. Although Si is abundant in soil, most of its sources are not available for plant uptake due to low solubility of Si compounds in soil. To improve plant-available Si in the soil, silicate solubilizing bacteria (SSB) are potentially important in solubilizing insoluble forms of silicate. The objectives of this study were to determine: (i) silicate solubilizing activity of Burkholderia cenocepacia KTG, Aeromonas punctata RJM3020, and B. vietnamiensis ZEO3 on magnesium trisilicate and quartz, (ii) biochemical characteristics of SSB, and (iii) solubilization of silicate, Ca, and Mg from quarts by SSB activity. A laboratory study was conducted at Microbiology and Environment Laboratory, the Indonesian Research Institute for Biotechnology and Bioindustry, Bogor, in 2016. All SSB were grown on Bunt and Rovira media containing 0.25% magnesium trisilicate or quartz as substrate, respectively. Silica solubilizing activities by SSB were determined by using inductively coupled plasma-atomic emission spectrometry while organic acid concentration in the culture were measured by using highperformance liquid chromatography (HPLC

“…Also Guntzer et al (2012b), in their long-term experiments conducted at Rothamsted, demonstrated that liming significantly increases the amounts of the available forms of silicon in the soil. By comparison, Kim et al (2010) showed that long-term mineral and organic fertilization in the absence of liming did not affect the available silicon content of a sandy soil over a 56-year period.…”
