“…Te use of a combination ameliorant could be an alternative option to improve the soil fertility. In such regions of a serious problematic soil fertility issue, integrated soil fertility management was therefore suggested and has already been implemented by agricultural users in Kenya, Rwanda, Ethiopia, and Malawi [3,5,9,10].…”

The physicochemical properties of Western Ethiopian soils were negatively threatened with continuous cultivation crop lands. Soil amendments with biochar and lime facilitate and improve soil physicochemical properties directly and indirectly and enhance crop productivity. A field experiment was conducted in Gimbi District, Western Ethiopia, to examine the effects of combined coffee husk biochar (CHB) and soil test value-based lime (STV) rate application on physicochemical properties of acid soils. The trial included eight treatments, including control, 100% STV, 10 ton of CHB, and CHB + STV rates at 10 ton + 75%, 10 ton + 50%, 7.5 ton + 75%, 7.5 ton + 50%, and 5 ton + 75% ha−1on two farm fields. The fields were laid out in RCBD with three replications. The treatments had substantial effects on P<0.05) on the soil’s physicochemical characteristics. The application of biochar and lime in Farms-1 and 2 reduced soil BD from 1.21 and 1.41 g·cm−3 to 1.15 and 1.12 to 0.90 and 0.97 g·cm−3, respectively. The soil pH level was increased from 5.10 to a range of 5.58 to 6.11 in Farm-1, and in Farm-2, from 4.64 to a range of 4.64 to 6.22 levels. The application of 10 ton of CHB + 75% of STV in Farms-1 and 2 resulted in the highest SOC of 7.44% and 7.68%, respectively. The application of 10 ton of CHB + 75% of STV in Farms-1 and 2 resulted in 4.86 mg·kg−1 and 6.96 mg·kg−1 available P, respectively. Available P was positively correlated with pH (0.62), SOC (0.63), and CEC (0.66). Exchangeable acidity was decreased from 4.64 cmol(+)kg−1 to a range from 3.19 to 0.98 cmol(+)kg−1 in Farm-1 and from 5.00 cmol(+)kg−1 to a range from 3.38 to 1.10 cmol(+)kg−1 in Farm-2. Therefore, amending the strongly acidic to very strongly acidic soil with a combined CHB (7.5 to 10 ton ha−1) and STV (50 to 75% ha−1) rates had improved the soil physicochemical properties of agricultural lands. To make a firm conclusion, research on soil analysis after crop harvest and economic benefit is required.

The main chemical, physical, and biological limitations on soil production in western Ethiopia include low soil fertility, nutrient unavailability, and acidity. Therefore, the purpose of the study was to evaluate how specific physico-chemical properties of soil were influenced by the combined application of vermicompost and NPS fertilizer rates at Bako Agricultural Research Center. Four vermicompost levels (0, 2.32, 3.48, and 4.64 tons ha− 1) and four NPS fertilizer levels (0, 50, 75, and 100 kg ha− 1) were combined in a factorial manner were laid out in Randomized Complete Block Design (RCBD) with three replications. The study's findings demonstrated that while bulk density decreased below the control due to different levels of organic fertilizer application, all treatments applied increased soil moisture and total porosity relative to the control or NPS fertilizer alone. The results showed that the combination of vermicompost and NPS fertilizer rates significantly affected organic carbon, organic matter, total nitrogen, basic cations (Ca2+, Mg2+, K+), and available phosphorous. Nevertheless, the experiment indicated the integration of organic and inorganic fertilizers to enhance nutrient availability by maintaining soil fertility and health because the pH of the soil was significantly influenced by the primary effects of vermicompost levels (P ≤ 0.01).

An experiment was conducted to evaluate the response of black cumin (Nigella sativa L.) to vermicompost and nitrogen (N) fertilizer rates. Four rates of vermicompost and four rates of N were laid out in a randomized complete block design with three replications. The results showed that the interaction effects of nitrogen fertilizer and vermicompost rates significantly influenced black cumin growth, yield, and yield component parameters. The maximum seed yield (1,090 kg ha–1) was obtained from the combined application of 5 Mg ha–1 vermicompost and 60 kg ha–1 urea‐N. Therefore, it can be concluded that the combination of these treatments gives a better yield and yield components of black cumin in the study area.
