“…However, Soil chemical degradation such as (soil acidity, salinity and sodicity, low levels of fertilizers), pesticides and improved seeds, moisture stress, are some of the major crop production constraints in Ethiopia (Taffesse et al, 2011). Acid soil infertility is a major limitation to crop production on highly weathered and leached soils in the tropical and temperate regions of the world (Uexküll and Mutert, 1995), particularly in tsegede highlands (Kidanemariam et al, 2013). In addition to this, the fertilizer use focus was only on N and P fertilizers in the form of diammonium phosphate (DAP) and urea for all cultivated crops in all agro ecologies and on all soil types for the last several years.…”

“…Among the key strategies that were identified to help increase agricultural production and productivity in the Growth and Transformation Program one (GTP1) period was the soil fertility mapping of the country's agricultural lands. In Tsegede highlands four soil nutrients {Nitrogen (N), phosphorus (P), Sulfur (S) and Boron (B)} are found to be deficient in the soils (MOA and ATA, 2014), and characterized by low pH level and high Exchangeable Aluminum (Kidanemariam et al, 2013) and (MOA and ATA, 2014). About 30% of the highly weathered soils of Ethiopia have been reported to be acidic (Mamo et al, 1988) and more than 81% of the Tsegede highlands are under strong acid (Kidanemariam et al, 2013).…”

A field experiment was carried out during 2012/2013 on acidic soil of Tsegede highlands, Northern Ethiopia to evaluate wheat crop response to different Fertilizers and Liming with four treatments: (1) (No fertilizer), (2) 64 kg/ha Nitrogen+ 150 kg/ha Minjingu organic hyper phosphate fertilizer, (3) 64 kg/ha Nitrogen and 20 kg/ha Phosphorus, and (4) 64 kg/ha Nitrogen and 20 kg/ha Phosphorus + 4.17 t/ha lime were arranged in Randomized Complete Block Design (RCBD) deign with three replications. Soil samples were collected before planting and analyzed for selected physicochemical properties, which revealed that textural class was sandy loam and the pH, Exchangeable aluminum and Exchangeable Acid as very strong acid and toxic for plant growth. The total percentage of organic matter, Nitrogen and Cation Exchange capacity (CEC) were as high; while very low in available phosphorus. Results indicated soil that received 64 kg/ha Nitrogen from urea+150 kg/ha Minjingu organic hyper phosphate, 64 kg/ha Nitrogen and 20 Phosphorus and 64 kg/ha Nitrogen and 20 kg/ha Phosphorus + 4.17 t/ha lime gave additional grain yield increment by about 191, 211 and 413% over the control, respectively. While the straw yield improved by 226, 248 and 422% respectively. The highest yield was recorded on soils with 64 kg/ha Nitrogen and 20 kg/ha Phosphorus along with lime followed by the 64 kg/ha Nitrogen and 20 kg/ha Phosphorus, and soil with application of 64 kg/ha Nitrogen from urea+150 kg/ha Minjingu organic hyper phosphate. The recorded plant height was significantly affected only at 64 kg/ha Nitrogen and 20 kg/ha Phosphorus + 4.17 t/ha lime (21.2%) over the control. Hence uncontrolled land encroachment in the low land areas can minimize to make these farmlands productive. The rate of these fertilizers and marginal rate of return was not studied.

“…Under acidic soil conditions there has been a gradual depletion of soil bases (such as Ca, Mg and K) and soil acidity developed. Soil acidity mainly at soil pH < 5.5 affects the growth of crops due to high concentration of aluminum (Al) and manganese (Mn), and deficiency of P, nitrogen (N), sulfur (S) and other nutrients (Abreha, 2013).…”

). Integrated reclamation approach centring limefertilizer and soil nutrients interaction is vital to establish cost effective and sustainable nutrient management of this soil. 50% FYM + 50% NP + 50% lime treatment gave significant yield and yield component of teff at Nedjo testing site, this result showed that proper knowledge and enhanced use of integrated soil fertility management technologies such as combined use of organic and inorganic fertilizers in the presence of a soil-conditioner lime are vital in improving and sustaining crop production. From an experiment conducted to evaluate the effectiveness of limes produced at different locations in Ethiopia no statistical yield difference was observed, and this implies that both lime produced at Senkele (Oromia region) and Dejen (Amhara region) can successfully answer their regional lime needs. When Senkele lime, Dejen lime and Ca(OH)2 from Ghion gas factory were compared with Awash calcite and Awash dolomite, these two Awash products were greatly preferred. The reason might be mainly from the material they are processed and as well the technology under which they were crushed.

The soil acidity level is a key soil characteristic that determines soil nutrient availability, soil microbial activities, and crop growth. This study was carried out to predict the extent and severity of soil acidity based on 109,704 soil pH samples collected from soil laboratories and compiled from various studies. Rainfall, altitude, slope gradient, soil, and land cover were considered to generate multivariate interpolated soil pH surface. The performance of the co-kriging model was found to be satisfactory with a standard error of 0.77, root mean square error of 0.51, and R 2 of 0.74. The model estimates showed that 47% of the Country's total area and 45% of the rainfed areas are acidic (pH < 6.5). Out of the total area of the Country, 3.7% (42,264 km 2 ) is found to be extreme to strong acidic (pH < 5.5), 20.7% (236,724 km 2 ) is moderate acidic (5.6 < pH < 6.0), and 22.5% (257,290 km 2 ) is slight acidic (6.0 < pH < 6.5), whereas the respective coverage in the rainfed agricultural areas is found to be 12% (80,732 km 2 ), 18% (120,500 km 2 ), and 14.6% (97,202 km 2 ). As informed by the model results, integrated acid soil management efforts should be given a priority to severe soil acidity areas of western, central, northwestern, and southern parts of the Country. Thus, appropriate integrated land management techniques that enable to reduce soil acidity and halt land degradation should be initiated, informed by the map produced. Regularly updating the extent and distribution of surface and sub-surface soil acidity is recommended in future studies.
