As for the hyphen, again FAO recommended word list says:

agro- compounds closed up except before vowel, e.g. agro-ecology, agro-ecosystem, agro-industry, agroforestry, agrometeorology, agrosilvicultural, agrosilvipastoral
http://www.fao.org/docrep/004/ac339e/AC339E02.htm

This reference also adds a variation to my suggestions as "silvi" instead "silvo".
