Recognize the problem
Post-harvest losses are a common problem in maize production. Some farmers
are storing maize before the cobs and grains are dry enough. Then fungal
diseases germinate on the grains and destroy them.
Background
Farmers must dry or wait for their maize grains to dry in order to avoid
germination of fungal diseases in the...

FACTSHEETS FOR FARMERS
www.plantwise.orgCreated in Zambia, July 2014
Soil conservation using a magoye ripper
Recognize the problem
Frequent turning of top soil under conventional farming has made the soil loose
and therefore prone to erosion by wind and water. Soil erosion washes away
the nutrients from the organic manure and fertilizer in the soil. This causes a
plough pan that hinders plant growth, and the loss of moisture that would have...
