Time of Lime Application on Performance of Food Barely in Acidic Soil, Gummer District, Southern Highland Ethiopia
Abstract: Soil acidity is the main bottleneck to crop production, causing reduced yields in highlands areas with heavy rainfall. Lime application is the most common method of restoring soil acidity and can increase soil pH, improve nutrient availability for plants, and alter physical, chemical, and biological properties of soils. However, the lime application time varies greatly along the boundary and deviates from the time recommended by different researchers. The experiment was …
