Container vs. field production

•

Containers

– No seed bank

– Bark substrates are free

of weeds initially

– Isolated substrate

volume

– No postemergence

herbicides

– No cultivation

•

Field crops

– Abundant seed bank

– Abundant weed seeds and

perennial propagules

– Soil is continuous

– Many postemergence

herbicides (directed apps.)

– Cultivation equipment is

common and efficient
