Soil Amendments for Healthier Soils

Dr. Thomas L. Thompson

This article is from ECHO Asia Note # 36.

Soil chemical, physical, and biological properties range from those highly favorable to plant growth to those highly unfavorable to plant growth. It is rare—especially in the tropics—to find a soil in its natural state in which all properties are highly favorable to plant growth. Nevertheless, as long as there is sufficient soil depth to provide an adequately deep and well-drained root zone, proper amendment and management of soil properties can result in almost any soil becoming suitable for plant growth. Even naturally infertile soils and soils with very low water-holding capacity can produce extraordinarily high crop yields with proper management and inputs. 

The Value of a Seed: Growing a Network of Community Level Seed Banks in Asia

Patrick Trail

As an organization that seeks to equip people with agricultural resources and skills, we often find ourselves coming back to the seed. Again and again we witness the value saving open-pollinated seeds, shedding light on locally adapted and underutilized plants of merit, and researching innovative low-cost seed storage technologies. These activities form the foundation of ECHO’s ability to empower others in their endeavors to improve food and agricultural systems around the world.

Building on a longstanding history of seed bank operations, first in Florida, and now Asia and Africa, ECHO continues to expand its capacity for placing seeds into the hands of those in need. In 2009, with the establishment of Asia’s Regional Impact Center and Seed Bank, the first step was taken in an ongoing process to house seeds of regional merit and local importance on location. To date, ECHO’s first regional seedbank strives to meet a growing demand for locally-adapted, open-pollinated seed from within our network, and its success attests to the wisdom of its establishment. Distributing over 4,600 trial seed packets in 2017, from a selection of 175 different varieties, the Asia Seed Bank serviced network partners in 29 countries, with seeds grown and produced right here in SE Asia!
