Empirical scientific evidence indicates that there is still room for increasing food production by improving land productivity. This study aimed at identifying the key determinants that govern farmers’ decisions to adopt multiple components of integrated soil fertility management (ISFM) in a maize mixed cropping system of the Chinyanja Triangle, Southern Africa. Revealed preferences of ISFM components were collected from 320 randomly selected households and multivariate probit (MVP) model was used to analyse the simultaneous effects on adoption based on biophysical plot and household‐level socioeconomic attributes. The results show that farmers’ choices of a set of ISFM components are determined by a mix of factors that address the trade‐offs and synergies among them. Non‐farm income, moderate land quality perception, and education influence simultaneous technology adoption, while gender and crop loss increase the likelihood of farmers’ decisions to adopt independent options. Having other sources of income supports co‐adoption of inorganic fertilizer, residue incorporation, and crop rotation. Input/output market access, access to information, financial sources, and climate variability also play pivotal role in technology adoption. These results indicate that resource availability, learning costs, finances, and risk aversion need to be considered when designing and promoting ISFM technologies as a package.

南部非洲Chinyanja Triangle同时采用土壤肥力综合管理技术

经验科学证据表明，仍有通过提高土地生产力来增加粮食产量的空间。这项研究旨在确定关键因素，这些因素决定着农民决定在南部非洲Chinyanja Triangle的玉米混合种植系统中采用综合土壤肥力管理（ISFM）的多个组成部分的决定。从320个随机选择的家庭中收集了ISFM组件的显式偏好，并使用多变量概率（MVP）模型基于生物物理图和家庭水平的社会经济属性来分析对采用的同时影响。结果表明，农民对一系列ISFM组成部分的选择是由解决这些因素之间的取舍和协同作用的因素决定的。非农业收入，对土地质量的感知中等，和教育影响同时采用技术，而性别和农作物损失增加了农民决定采用独立选择的可能性。有其他收入来源可支持同时采用无机肥料，残渣掺入和轮作。投入/产出市场准入，信息获取，资金来源和气候多变性在技术采用中也起着关键作用。这些结果表明，在设计和推广ISFM技术时，需要考虑资源可用性，学习成本，财务和风险规避。投入/产出市场准入，信息获取，资金来源和气候多变性在技术采用中也起着关键作用。这些结果表明，在设计和推广ISFM技术时，需要考虑资源可用性，学习成本，财务和风险规避。投入/产出市场准入，信息获取，资金来源和气候多变性在技术采用中也起着关键作用。这些结果表明，在设计和推广ISFM技术时，需要考虑资源可用性，学习成本，财务和风险规避。
