Effect of biochar, farmyard manure, and lime on soil properties, and on growth and nutrient uptake of wheat on acidic soils in Southern Ethiopia

State of the art of biochar in Ethiopia. A review

“… Biochar source Usage % of improvement References P. hysterophorus weed Increase soil moisture 21.6 % [ 94 ] Maize cob biochar mixed with NPS fertilizer Studying Growth and yield of maize crop 16.8 % [ 97 ] parthenium hysterophorus Adsorption of Cr(VI) combined with magnetite 17.3–98.1 % [ 102 ] Coffee husk Phosphate removal 20–30 % [ 101 ] Parthenium biochar Study the changes in the physicochemical properties and agronomic performance of wheat on acidic soil Acidic soil was improved and good results were observed. [ 103 ] Eucalyptus wood Water treatment combined with Teff straw and sand 92–99 % (solid and suspended solids removal) 79–83 % (alkalinity removal) [ 100 ] Coffee husk Nutrient uptake of coffee growth 43–46 % depending on pot size [ 96 ] Biochar, farmyard manure and lime Chemical property of soil and wheat attribute Biochar greatly changes soil chemical property and wheat attribute [ 104 ] biochar and deficit irrigation enhanced growth woody species seedlings 44 [ 99 ] Coffee husk biochar and bone char Phosphorus adsorption-desorption capacity of soil and crop yield Biochar and bone char increases the soil phosphorus adsorption desorption and crop yield …”

Response of Garlic (Allium sativum L.) Yield to Combined Biochar, Lime, and Inorganic‐Fertilizer Rates in the Case of Gimbi District, Western Ethiopia

“…The T6 ha −1 recorded the lowest HI% (0.50%), while T1, T7, and T8 all achieved the highest HI% (0.83%). The benefits of integrated fertilizers, particularly by the organic input and lime combined with mineral fertilizers were identified by many scholars [74][75][76].…”
