Soil And Irrigation

Horticulture Innovation Lab research related to irrigation practices and soil health examine constraints to irrigation adoption, effects of conservation agriculture practices on horticultural crops, low-cost methods to improve soil health, and farmer-led irrigation processes to make irrigation more widely available for smallholder vegetable farmers.

Projects

Promoting technology for horticulture production as adaptation to climate change in Guatemala

Led by Rolando Cifuentes, Universidad del Valle de Guatemala (UVG)

For highland farmers who face elevated risks due to climate change, this project identifies the most effective protective structures, irrigation technologies, practices to improve soil health, and postharvest management practices to ensure the production of high-quality, safe, and nutritious produce.

Developing innovative horticulture technologies for small-scale women farmers in Uganda

Developing innovative horticulture technologies for improved income and livelihoods among women small-scale producers in Uganda

Led by Robert Kajobe, Muni University

Through identification of practices to reduce pre- and post-harvest losses, along with effective marketing and market access strategies of vegetables, this project will improve household nutrition, increase sales, and elevate the household income status of women small-scale vegetable producers.

Improving soil health for increased yields, profitability and enhanced nutrition in Nepal and Bangladesh

In Nepal, a lack of crop rotation has exacerbated soilborne diseases, leading to decreased farm profitability and discouraging younger generations from farming. Learn how Dr. Ram B. Khadka and Dr. Ranjana Rawal are addressing these issues through anaerobic soil disinfestation (ASD) trials and capacity strengthening of the farmers in the form of mother and baby trials.
