Feed Systems and Facilitative Intercrops
Often fronted by the dual-output, seasonal intercrop, agroecology is far from limited to this form. Within the threats that constrain yields, there are some that can be overcome by the planting of a second or even a third species. Lacking a second output, this is the facilitative intercrop. There are a number of facilitative-based agrotechnologies.
In addition, there are those agrosystems where livestock, of various forms, feed. Animal forage can be considered as just another crop. However, when the animals are present, there are nuances.
Because of this, feed systems are treated as separate topic. Inclusive is a brief mention of those feed systems involving eatable insects and aquatic animals.
