Soil acidity is one of
chemical soil degradation problems which affect productivity of the soil
in Ethiopian highlands. The purpose of this research was to identify the
status of soil acidity and determine the amount of lime requirement for
neutralization to increase plant nutrient availability in Welmera woreda,
Oromia region. More specifically the study pointed out statistically,
the nutrient availability before and after liming acidic soil using
paired t-test. The results indicated that the soil of study area was
strongly acidic (pH < 5.3) and exchangeable acidity was from 2.86±0.01 -
3.55±0.07 cmol/Kg. The soil showed low concentration of plant nutrients
(AP, TN, K,Ca,Mg) and high in micronutrients (Cu, Fe, Mn, Zn) contents.
After 90 days liming in greenhouse incubation of the soils, the results
showed effective neutralization of the soil, which indicated it was
properly limed and the effects of soil acidity on nutrient availability
was clearly observed. The concentration of all anions(AP,TN, and OC),
cations (Na+, K+, Ca+2 and Mg+2) and micronutrients were found to be
significantly different except TN and OC, between the soil samples for
before and after liming. After limed acidic soils, anion and cations are
improved their availability for plant while micronutrients are decreased
from toxicity to normal condition. How to cite this article: Dinkecha K, Tsegaye D (2018 Effects of Liming on Physicochemical Properties and Nutrient Availability of Acidic Soils in Welmera Woreda, Central Highlands of Ethiopia. Acad. Res. J. Agri. Sci. Res. 6(1): 20-28
