“…These data suggest that the plant Si uptake accelerated the release of dissolved Si from both silica gels and soil. These results agree with the observation reported by Marxen et al (2016) in which the decreased Si concentrations in soil solutions would accelerate the release of Si from rice straw and soils.…”

“…It might be possible that decomposition of organic materials (MM, cacao SB and RSC) occurred slowly. Marxen et al (2016) reported that Si concentrations in soil solution increased when the organic matrix surrounding the phytoliths was decomposed and the surface of phytoliths was exposed to the soil solution. Another possibility is that the available Si in most organic materials (1.47-3.74 g Si kg -1 ) was lower compared to Si in inorganic materials (6.54-16.14 g Si kg -1 ).…”

Plants absorb silicon (Si) from soil solution in the form of monosilicic acid, also called orthosilicic acid (H 4 SiO 4 ). Application of organic and inorganic materials containing readily soluble Si can increase Si supply in the soil and its uptake by plant. The study aimed to evaluate the release of Si from organic and inorganic material sources and its uptake by rice plant. The released phosphorus (P) from those materials was also evaluated. The inorganic materials evaluated included fly ash, steel slag, silica gel and Japanese silica gel (JSG), while the organic materials consisted of rice husk ash (RHA), rice husk burnt (RHB), media of mushroom (MM), cacao shell biochar (cacao SB) and rice straw compost (RSC). The dynamics of Si and P were observed by periodical samplings at 7, 17, 24 and 34 days after transplanting (DAT). Tiller number and plant height were measured at 16, 21 and 36 DAT. The results showed that Si concentration in solution derived from inorganic material was highest for JSG followed by silica gel (1.107 and 0.806 mmol L -1 , respectively). The release of Si from organic material was higher for RHB and RHA (0.618 and 0.539 mmol L -1 , respectively). Cacao SB, silica gel, JSG and RHB significantly increased plant height at 36 DAT. Meanwhile, Si materials did not significantly affect the tiller number. Of the materials used, steel slag and JSG significantly affected Si uptake by rice plant.[Keywords: rice, silicate materials, silicon, silicon uptake] ABSTRAK Tanaman menyerap silikon dari larutan tanah dalam bentuk asam monosilikat, yang juga disebut asam ortosilikat (H 4 SiO4

“…For instance, interviewing farmers revealed that at some of the research sites the rice straw is permanently removed from the paddy fields after harvest. This finding stimulated research on importance of rice straw decomposition as source of plant-available silicon in a Vietnamese region where low concentrations of plant-available silicon in soil might limit rice yields (Marxen et al 2016;Klotzbücher et al this issue). Another example is the role of the giant earth worm in the Philippines; its existence, long claimed by farmers, was confirmed by scientific observation in the course of the project, but unlike farmers suspected, it was found not to be the reason for rice terrace damages.…”

The transdisciplinary research project LEGATO analysed the combined generation of provisioning, regulating and cultural ecosystem services in wet rice agriculture in South-East Asia and applied ecological engineering to future-proof it against global change and environmental pollution challenges. Due to its transdisciplinary character and the sheer size, a systematic stakeholder involvement was inevitable. Starting with stakeholder identification by snowballing from a limited number of contacts, we derived a multi-level stakeholder analysis and tried to involve those identified as relevant. Applying different means and aiming at different depth of involvement, the effort can be judged successful. The paper describes the methods used to identify and classify stakeholders, and key elements of the stakeholder management, guided by the BiodivERsA Stakeholder Activation Handbook. While on the local level, farmers and extension workers turned out to be influential and interested stakeholders in both countries, as well as local (PH) or provincial authorities (VN), differences were manifest on higher levels due to the divergent institutional setting. National-level agents were hard to get interested in both countries, and influential agents along the production chain, including middle men, were not really interested in collaboration.

Kandungan silika dalam jerami padi dapat mencapai 19,2% dari bahan kering (Chairunnisa et al, 2013), 15% (Sarnklong et al, 2010), 13,94% (Binod et al, 2010), 11% (Phutela, 2011), 10,7% (Marxen et al, 2016), 7,12% (Antonius, 2010. Menurut Van Soest (1983) setiap kenaikan 1% kadar silika bahan akan menurunkan kecernaan sebesar 2 -3% pada rruminansia.…”

:The basic reason for poor performance of livestock in developing countries includes Indonesia, is qualitative fluctuations in the feed. Therefore knowledge in utilizing agroindustry byproduct as feedstuff to meet the nutrient requirement of animals is important. Rice straw is a crop residue of rice production and can be used as a feed for ruminants because it is easily and cheaply available in many Asian countries. Rice straws have low nutritive value and it is generally limited by several factors such as the low nutritional quality due to high fiber content and lignification process. In Indonesia, rice straw has been widely utilized in livestock feeding systems, thus the need to improve them is imperative as they are an abundant crop residue. Much more attention has been paid to improving its feeding value in order to increase livestock productivity. Many processing methods to improve the nutritive value of rice straw have been investigated. These methods can be classified as physical, chemical or biological. Usually, processing methods improve the nutritive value of straw by increasing its digestible energy content, by increasing feed intake, or by a combination of the two. This paper aims to examine the potential of rice straw as basal feed livestock as well as efforts to improve their nutritional value.
