Silicon nutrition

Silicon in grass. Plant nutrition studies 1
Grasses need silicon. In this desk study the literature about effects of silicon on growth, development, productivity and resistance to diseases, insects and abiotic stress have been opened up. An overview with crucial data of some tens of experiments and a comprehensive list of references with hyperlinks are included as well. Since most aspects of silicon nutrition of grasses are only roughly examined, the report contains recommendations for field-testing of silicon application in the culture or management of ornamental, seed and turf grass. Silicon in grass is available in a Dutch version.

Expected publication date of English version: December 2008.
