      Background and Objective: Detailed characterization of bio-physical resources in agricultural landscapes and documenting locally used soil fertility management practices is required for developing site-specific management scenarios in the study area. In view of this, a study was conducted to characterize the landscape features and related biophysical settings and to identify the local soil. Soil Porosity and Permeability • Porosity is the total amount of pore space in the soil (30 to 60%) – Affects the storage of air and water – Affects the rate of movement of air and water • Permeability is the ease in which water, air, and plant roots move through the soil – Ease of air, water and root movement – Affects rate of water intake and drainage.

      Vertisols are among the most common, high‐potential soils in the central highlands of Ethiopia, where over 88% of human and 77% of the livestock population are located. Productivity from these soils is constrained by severe waterlogging due to their physical properties and intensive rainfall in summer. Soil - Soil - Soil classification: The two principal systems of soil classification in use today are the soil order system of the U.S. Soil Taxonomy and the soil group system, published as the World Reference Base for Soil Resources, developed by the Food and Agriculture Organization (FAO) of the United Nations. Both of these systems are morphogenetic, in that they use structural properties as.

        Low agricultural productivity caused by soil degradation is a serious problem in the Ethiopian Highlands. Here, we report how differences in soil fertility management between farming systems, based either on enset (Ensete ventricosum) or on teff (Eragrostis tef) as the major crops, affect the extent of nutrient stocks, balances and ecosystem sustainability.

on Management of Vertisols in Sub-Saharan Africa.

In Ethiopia, Vertisols are widely and intensively utilized soil types covering 11% or million hectares (ha) of the total land mass and is the fourth important major soil group.

3 More than half (million ha) of the Vertisols are found in the central highlands with altitude of more than meters above sea level (masl). Generally. SOIL NUTRIENTS, SOURCES AND UPTAKE Essential Plant Nutrients All green plants have the ability to manufacture their own food by using energy derived from the sun to combine chemical elements, taken up in the inorganic ion form, into a multitude of organic compounds.

Seventeen elements are considered essential for plant growth. From the present study, it can be concluded that the soil analysis data of wheat fields in central highland Vertisols of Ethiopia showed deficiency in the levels of N, P, S, Zn, Mo and B.

Moreover, the plant analysis data from the same sites indicated that wheat plants were deficient in N, P, Zn and K. Vertisols, because of their high water-holding capacity, are suited to dryland crop production in semi-arid environments with uncertain and heavy rainfall, Selected physical and chemical properties of Vertisols that affect their' management for crop production are discussed.

Due to their high clay content. In order to improve wheat yields, field experiments were established in the and cropping seasons on two rainfed locations in central highland Vertisols in Ethiopia to determine the response of bread wheat (Triticum aestivum L.) to phosphorus (P) and potassium (K) fertilization along with other limiting nutrients.

soil quality of Vertisols, compared with prevailing traditional farming practices. Initiated inthe improved system consisted of integrated land management to conserve soil and water, with excess rainwater being removed in a controlled manner. This was combined with improved crop rotation (legume based) and integrated nutrient management.

Understanding Soil Nutrients / 35 The Plant and Soil Ecosystem Plants depend on soil for air, water, nutrients, and mechanical support. In order to accomplish this, a soil should be maintained in as healthy a condition as possible. Keep in mind that soil fertility is a delicate bal-ance of the physical, biological, and chemical properties.

Ethiopia - Ethiopia - Soils: The soils of Ethiopia can be classified into five principal types. The first type is composed of euritic nitosols and andosols and is found on portions of the Western and Eastern highlands.

These soils are formed from volcanic material and, with proper management, have medium to high potential for rain-fed agriculture. Soil is a major source of nutrients for plant growth. Nutrients supplied by the soil are called mineral nutrients. The non-mineral nutrients such as carbon (C), hydrogen (H) and oxygen (O) come from air and water during photosynthesis.

Soil mineral nutrients are separated into two groups the macro and micronutrients. IFPRI (International Food and Policy Research Institute). Fertilizer and Soil Fertility Potential in Ethiopia.
