This is a presentation from Bruce French from Food Plants International. Agro-ecology or how plants grow in nature Naturally plants are not in rows! Using only one kind is not used in nature! Lots of varieties are maintained in nature! In nature the right plant grows in the right place! In nature fruit is produced in season! Nutrients are recycled in nature! Natural systems are sustainable! In nature the soil remains alive and humus rich!

Agro-ecology – means growing plants a natural way
