4. Soil Fertility Evaluation and Mapping in Sdeyni Watershed, Habru District, Northeastern Ethiopia

Author

Abstract

Soil nutrient mining, poor use of external inputs, soil erosion, are the major soil constraints affecting sustainable crop production in Ethiopia. In the study area, the soils were not characterized to provide location specific information for crop producers. Thus, this study was initiated with the objective of evaluation and mapping of soil fertility in Sdeyni Watershed. Cultivated lands in the watershed were selected and divided into eight land units (LUs). Three replicated composite soil samples were collected from the depths of 0-20 cm from each land unit comprising a total of 24 composite soil samples. Data analysis was done following one way ANOVA using R software, and mapping was performed using GIS software. The result showed that most soil properties were significantly different in the land units. Clay texture, slightly acidic soils (6.02-6.74), medium organic matter (OM) content (2.96-4.59%), low to medium total nitrogen (0.10-0.24%), medium to high available phosphorus (6.40-12.44 mg kg-1), and medium to high cation exchange capacity (11.90-27.00 cmol (+) kg-1), and moderate to high percent base saturation (41.40- 67.23%) were the observed soil fertility parameters. Soil fertility management through addition of organic and inorganic fertilizer sources should get immediate attention to maintain optimum crop production sustainably.

19. Land Use and Land Cover Dynamics and Properties of Soils under Different Land Uses in the Tejibara Watershed, Ethiopia.

Abstract

Land use changes have long been considered among many factors responsible for physical and chemical soil degradation. This study was conducted to evaluate land use and land cover (LULC) changes and their cumulative effects over 30 years (from 1989 to 2019) on the current physical and chemical properties of soils in the Tejibara watershed, Ethiopia. Image analysis and LULC classifications were performed using ERDAS IMAGINE 2014 and ArcGIS 10.4 software, respectively. For the determination of soil properties, four land use types (natural forest, eucalyptus plantation, cultivated, and grazing lands) and two soil depths (0-20 and 20-40 cm) were used. Triplicate composite soil samples were collected from each land use type and soil depths. For the determination of physical (texture and bulk density) and chemical soil properties such as electrical conductivity (EC), organic matter (OM), total nitrogen (TN), and available phosphorus (AP), standard laboratory procedures were employed. The image analysis results for all of the years studied show that cultivated lands have increased in area at the expense of forest and grazing lands. Silt content, clay content, AP, and pH were significantly affected by land use as the main effect while the interaction effects of soil depth and land use were significant for total N and OM only. The highest (10.1 mg/kg) and the lowest (4.9 mg/kg) AP contents were observed in the forest and the grazing lands, respectively. Soil total N content was highest in the forest lands (0.32%) and lowest in cultivated lands (0.06%). Concerning OM content, the highest (11.0%) and the lowest (0.8%) values were recorded in the forest and cultivated lands, respectively. Generally, this study showed that land use changes have reduced the areal coverage by forest and grazing lands and have negatively affected the soil properties. This implies that land use change without soil fertility measures that are appropriate to the area could cause enhanced land degradation and thereby reduce the productivity of the study area soils., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Sabiela Fekad Fentie et al.)
