Chemical soil properties in agroecosystem around Mt. Kilimanjaro

We assessed variation of soil chemical parameters from a total of 24 villages. Sampling plots were established across the three major agro-ecological zones, the lower, mid and upper elevation zone and between maize and agroforestry. 30cm deep pit was dug, 0.5 kg of homogenous disturbed sample was extracted and stored in labeled plastic bags. In laboratory, standard protocols were used to determine the following data; Total N, Total C and Total P, Mg, Mn, Al, Fe, Na, Ca, pH, CECeff, CECaa and CECbsat
