Abstract
Corn productivity indices (CSR2T) for representative soils in the Southern Highland Zone of Tanzania were
developed. The approaches used were derived from Iowa State University’s CSR2. Consistent with ISU, index points were
applied to the pedon based on the USDA Soil Taxonomy subgroup, family particle size class, and available water holding
capacity, solum depth and resilience to degradation characterizations. Additional index points were applied based on field
conditions especially slope, erosion history and flooding or ponding risk in order to determine the inherent productivity
potential of the soils in the work sites. The results were used to develop the Corn Suitability Rating in Tanzania (CSR2T) for
the soil settings of Southern Highlands. Sites’ characterization results were linked with the maize field experimental results
from 2003 to 2016 to determine the inherent corn productivity indices for the sites. The soils were found to have CSR2T values
of 72, 56, 62 and 48 for Uyole, Mbimba, Inyala and Seatondale farms, respectively. The soils of Seatondale were observed to
be more limited by water holding capacity. However, generally the study soils are observed to have good pedogenic potential
for corn productivity and very minimal pedogenic limitations for corn productivity. The most serious limitation seems to be
low water holding capacity
