Ethiopia is the most soil fertility-degraded part of the world, caused by continuous cultivation of monocrops, insufficient organic matter application, and integrated soil fertility management (ISFM). The main objective of this study was to examine the adoption level and factors influencing ISFM in Siyadeberna Wayu Woreda, Amhara National Regional State, Ethiopia. A cross-sectional survey research design was used. A questionnaire and direct observations were used to collect data from 147 randomly selected households. Based on the objectives, the data was analysed using multiple regression models, binary logistic regression models, and descriptive statistics. Findings revealed that 32 (21.8%) of households were adopters of ISFM and 115 (78.2%) were non-adopters of ISFM. The most commonly used ISFM components on farmland were chemical fertiliser alone (65.3%), organic soil fertility improvement alone (0.7%), organic plus inorganic fertiliser (34%), and chemical fertiliser plus organic soil fertility improvement plus improved seed varieties (21.8%). The binary logistic regression analysis shows that education, distance of farmland from households, experimentation on ISFM practices done by farmers, observation of experimentation on the farmer training centre, trend of manure used for farmland, labour, and the frequency of DA support were statistically significant influences on the adoption of ISFM. The perception of farmers towards organic soil fertility improvement technologies was high. Adoption decisions on organic soil fertility improvement technologies by households were crop rotation by legumes (95.9%), animal manure (70.7%), composting (63.9%), farmyard manure (32.7%), green manure (10.9%), bio-fertiliser (10.9%), and agroforestry trees (6.1%), respectively, which were highly decided to adopt in the future. Therefore, as a recommendation, farmers should encourage increased training in animal manure use for farmland management, and the culture of cucumber storage should change with biogas production.
