The tree that can triple crop yields!

In Malawi, Africa, maize yields were observed to have increased up to 280 percent in the zone under the Acacia tree canopy compared with the zone outside the tree canopy.

What makes this particular acacia tree so ideal is “reverse leaf phenology.” This quality drives the tree to go dormant and shed its nitrogen-rich leaves during the early rainy season—when seeds are being planted and need the nitrogen—and then to re-grow its leaves when the dry season begins and crops are dormant.

This makes it highly compatible with food crops because it does not compete with them for light—only the bare branches of the tree’s canopy spread overhead while crops grow to maturity. Their leaves and pods provide a crucial source of fodder in the dry season for livestock when other plants have dried up.”
