该研究于2014年在位于ANRS北威洛区Gidan区的Abuhoy Gara流域进行。研究的目的是研究农民对土壤肥力评估的看法，并将其与研究人员使用的土壤肥力标准进行比较。为了解决这个问题，半结构化的访谈进行了60户深入了解土壤肥力管理的做法，当地的方法来评估一个领域的肥力状况，并在土壤肥力的趋势。33名农民被要求确定肥沃和贫瘠的土地。记录了这些田地在访谈中提到的指标方面的特点，并采集了土壤样本，在实验室进行理化分析。收集的数据按海拔、坡度和田地类型分组。研究发现，农民用来评估和监测土壤肥力的指标共有六项（土壤颜色、质地、土壤深度、地形、土壤排水和离家距离），分为三类：作物产量、土壤肥力和土壤退化。总体结果表明，农民对农田土壤肥力状况的评估与其中一些指标，特别是土壤颜色和质地，有很好的一致性，这些指标得到了更详细的检查。土壤理化分析结果与农户对土壤肥力的评价也有较好的一致性。与管理得当的土壤相比，不适当耕作下的土壤属性总体上呈现出肥力流失的趋势。土壤管理方式对土壤肥力指标有重大影响。为了实现土壤质量的可持续变化，研究活动必须遵循科学和参与性方法。因此，为了设计更适当的研究并促进与农民的明确沟通，研究人员需要认识到农民对土壤肥力评估的知识和看法。因为，由于它们包括了影响植物生长的所有土壤因素，农民对土壤肥力的看法被认为是比研究人员更长期的日常密切的实际经验发现。
The study was conducted at the Abuhoy Gara Catchment, which is located in the Gidan District of North Wello Zone in the ANRS in year 2014. The aim of the study was to study farmers’ perceptions about assessment of soil fertility and comparing them with the criteria of soil fertility used by researchers. To address this issue, semi-structured interviews were conducted in 60 households to gain insight into soil fertility management practices, local methods used to assess the fertility status of a field, and perceived trends in soil fertility. Thirty-three farmers were then asked to identify fertile and infertile fields. Characteristics of these fields in terms of the indicators mentioned in the interviews were recorded, and soil samples were taken for physicochemical analysis in a laboratory. The collected data were grouped according to altitude, slope and type of field. A total of six indicators (soil color, texture, soil depth, topography, soil drainage, and distance from home) were found to be used by farmers to evaluate and monitor soil fertility, which were classified into three categories: Crop production, soil fertility and soil degradation). The overall result showed that there was good agreement between farmers’ assessment of the soil fertility status of a field and a number of these indicators, particularly soil color and texture, which were examined in more detail. The soil physicochemical analysis also corresponded well with farmers’ assessment of soil fertility. The soil attributes under improper cultivated land showed an overall change towards the direction of loss of its fertility compared to the condition of the soils under proper management. The manner in which soils are managed has a major impact on soil fertility indicators. In order to bring sustainable change in soil quality, research activities must follow scientific and participatory approaches. Therefore, to design more appropriate research and to facilitate clear communication with farmers, researchers need to recognize farmers’ knowledge, perceptions about assessments of soil fertility. Because, as they included all soil factors affecting plant growth, farmers’ perceptions of soil fertility were found to be more long term day-to- day close practical experience finding than those of researchers.
