CPTM director John Carter said the use of lime in agriculture has been practiced since the 1970s. He said lime reduces the soil acidity and enables plants to absorb the nutrients, adding that the fertilizer application alone cannot improve crop yields in Zambia because the soils are acidic.
Commonwealth Partnership for Technology Management (CPTM) says lime application could increase Zambia’s crop yields from 1.5 tonnes per hectare to 10 tonnes. Lime is a mineral rich in calcium oxides and hydroxides
CPTM is a non-profit organisation established in 1995 to help Commonwealth countries become leading agents in economic advancement. The organization has since partnered with Global Grains, which focuses on improving food security in Zambia through the development of small-scale farming, to conduct trials in Mkushi on how the industrial mineral could improve maize yields.
