Deep Pipe Irrigation: an inexpensive and efficient method to irrigate crops and trees

Edward Berkelaar

 Deep pipe irrigation is fairly simple and inexpensive, does not require high quality water, and makes very efficient use of water.

Controlling Weeds in Tree Plantings

Overstory Issue 188 (about accelerated natural regeneration, or ANR) included information about weeding in forests. Here we share an excerpt on reducing competition with weeds.

Pot Drip System for Tree Irrigation

Dawn Berkelaar

A pot irrigation system was used to water newly planted mango grafts. Instead of direct watering, water was poured into four cylindrical clay pots installed around the plant.

Winged Bean Revisited

Tim Motis

Winged bean (Psophocarpus tetragonolobus), an amazingly productive and multi-purpose legume, grows as a vine typically staked on 1.5 to 2 m (5 to 6.5 ft) poles or trellises. Likely originating in the Asian tropics, it thrives in hot, humid areas and grows at elevations up to 2000 m (6562 ft).

New Advances in Rope Washer Pumps

Danny Blank

For many years, a popular demonstration on ECHO’s farm has been the rope washer pump, made from materials that are available in any country—PVC pipe, an old tire, rope, washers made from tires, and a little wood. Because it can be made on the farm it can also be repaired by those who made it.

“Cafeteria Feeding” of Chickens

George Peckham

Chickens are an important source of meat and eggs for many small-scale farmers. When only a few chickens are kept, they are usually able to meet their dietary needs with kitchen scraps and a bit of grain, and by scavenging for seeds, insects, worms, etc. However, if the flock size is increased without developing a good feeding plan, egg production usually declines.

How Will Using Agricultural Land for Biofuels Affect Smallholder Farmers in Developing Countries?

Martin Price

All of us must be wondering how smallholder farmers that we serve, as well as global consumers of food around the world, will be affected by the enormous efforts being made in both temperate and tropical countries to grow their own fuel and move toward energy independence.
