Soil erosion and nutrient depletion have been the major challenges in Ethiopia that adversely affect soil fertility and crop productivity. With the aim of curbing land degradation problems, efforts are underway on the implementation of soil and water conservation (SWC) practices. This research investigated the effects of SWC practices on soil properties and crop productivity in …
This paper reviews Ethiopia's experience and research progress in past soil and water conservation (SWC) efforts and suggests possible solutions for improvement. Although indigenous SWC techniques date back to 400 BC, institutionalized SWC activity in Ethiopia …

The soil acidity in Ethiopia is dominated by strong acid soils (pH 4.1–5.5) . The decline in soil fertility is caused by land use type changes [ 7 ]. The loss of soil fertility in Ethiopia is related mainly to cultural practices such as low fertilizer use, removal of vegetative cover, and burning plant residues or the annual burning of ...
As soil pH ranges 6.0 to 7.5 is ideal for P Higher Mg content, particularly in the subsoil horizons of availability (Havlin et al., 1999), high concentration of Pedon-3 suggests that the dominance of Mg-bearing available P is a reflection of slightly acidic to neutral soil minerals in the weathering environment.

retaining soil fertility in Ethiopia is the failure to return crop residues and animal manure to the soil [8]. These in turn reduce Ethiopia's agricultural gross domestic product (GDP) by 7% [1]. A variety of factors cause water logging and salinity problems . which have direct relationship with acidity and physicochemical properties of soil.
Soil acidity associated with soil fertility problems are the main constraints hindering barley production in most highlands of Ethiopia. Field experiment was conducted to evaluate effects of lime and phosphorus (P) fertilizer application to acid soils on grain yield of barley and soil chemical properties during 2009 to 2013 cropping seasons at Bedi in Western Ethiopia.
History: Jimma Agricultural Research Center was established in 1967. Currently,the Center has two subcenters: Gera and Haru and three testing sites, i.e., Mettu, Mugi and Agaro. The Center is mandated to coordinate coffee research nationally. Moreover, nationally, integrated soil fertility and crop
2. Chemical Soil Degradation: •Soil acidity About 40.9 % of Ethiopia is covered by acid soils 28% by moderately acidic soils (pH 4.5 - 5.5) 13% by strongly acidic soils (pH <4.5) •Soil salinity and sodicity 11 million ha of land in Ethiopia are salt affected soils about half of these soils are saline and the remaining half are saline-sodic and sodic soils

Land degradation is a major concern in Ethiopia since it leads to declining agricultural productivity, poverty and food insecurity. Soil degradation is one of the crucial issues in mountainous areas of Ethiopia which needs efforts to reduce it. In the last two decades, various soil and water conservation interventions had been introduced in to different parts of Ethiopia.
Since then, he has been working in Ethiopian Agricultural Research Organization (EARO) at Melkassa Agricultural Research Center as a Researcher. In September 2002, he joined the school of Graduate Studies of Alemaya University for postgraduate studies in the field of Soil and Water Engineering (Irrigation Engineering).
parts of the world, especially in developing nations like Ethiopia. Even though a number of soil and water conservation methods were introduced to combat land degradation, adoption of these practices remains below expectations. This research was conducted in the Koga watershed, near Lake Tana, in the catchment of a recently constructed dam.

The study examined the impact of deforestation and subsequent cultivation on soil fertility and acidity conditions under varying soil depths. Soil profiles were opened in two adjacent land units, namely forestland and arable land and samples were collected from genetic horizons. Deterioration of soil fertility was observed after deforestation and traditional cultivation.

Soil acidity is one of the major constraints affecting crop productivity. It affects about 43% of the cultivated land in humid and sub-humid highlands of Ethiopia. To fulfill the increasing demand ...
The main soil forming factors giving rise to increase in soil acidity involve climatic factors such as rainfall, temperature, topographic and morphological features (Abebe, 2007; Brady and Weil, 2016). Nitisol/Oxisol areas are the main soil classes dominated by soil acidity. In Ethiopia, these soils are predominantly acidic
Knowledge of the geographical distribution of soils is indispensable for policy and decision makers to achieve the goal of increasing agricultural production and reduce poverty, particularly in the Global South. A study was conducted to better understand the soilscapes of the Giba catchment (900–3300 m a.s.l.; 5133 km2) in northern Ethiopia, so as to sustain soil use and management.

Introduction. The pH of agricultural soils is almost always measured in water, although 0.01 m calcium chloride is sometimes used for research purposes (e.g. Blake et al., 1999) because it simulates the soil solution better than water.UK agricultural soils usually have a pH in water of between 5 (unlimed mineral soils) and 7.5 (chalky or limestone soils).
Ethiopia is one of the most well endowed countries in Sub-Saharan Africa in terms of natural resources (Gete et al. 2006). However, natural resource degradation in Ethiopia has been going on for centuries (Hurni et al. 2010). Similarly, Berry (2003) also stated that loss of land resource productivity is an important problem in Ethiopia
Soil acidity associated to Al toxicities, soil erosion and soil nutrient depletion are the main soil related constraints to agricultural development in parts of developing countries relying on agricultural to feed their growing population [].In Ethiopia, huge surface areas of the highlands located at almost all regional states of the country are affected by soil acidity.
Soil acidity is one of the major factors limiting soil fertility and crop production in large areas of Ethiopia. A two-month incubation experiment was conducted to evaluate the effects of lime, vermicompost (VC), and chemical phosphorus (P) fertilizer on selected chemical properties of Dystric Nitisols in Ebantu District, Western Ethiopia. The treatments comprised of three rates of lime (2, 4 ...
1. Introduction. Land degradation is a major problem in Ethiopia. It has a negative impact on agricultural economy and the natural environment Taddese (2001) clearly explained that the major causes of land degradation in Ethiopia are the rapid population increase, soil erosion, deforestation, low vegetative cover and unbalanced crop and livestock production.
