Soil Water Infrastructure to Eliminate Off-Site Nutrient Migration and Support Farm Profitability

Ontology-Based Simulation Applied to Soil, Water, and Nutrient Management

Ontology-based simulation is an approach to modeling in which an ontology is used to represent all elements of a model. In this approach, modeling is viewed as a knowledge representation problem rather than a software engineering problem. Ontology-based techniques can be applied to describe system structure, represent equations and symbols, establish connections to external databases, manage mo...

Migration and Local Off-farm Working in Rural China

The paper analyzes the decision-making of rural Chinese households on whether to stay exclusively on farm, take local off-farm jobs or migrate. Based on a survey of rural Chinese households, we examined the determinants of job location choice of rural China. We extend the dynamic discrete choice model of Wooldridge (2002a,b) to the three-alternative setting and apply it to a five-year panel. We...

Automated configuration support for infrastructure migration to the cloud

With an increasing number of cloud computing offerings in the market, migrating an existing computational infrastructure to the cloud requires comparison of different offers in order to find the most suitable configuration. Cloud providers offer many configuration options, such as location, purchasing mode, redundancy, extra storage, etc. Often, the information about such options is not well or...

Sustainable nutrient management at field , farm and regional level : soil testing , nutrient budgets and the trade - off between lime application and greenhouse gas emissions

Pollution from agriculture has environmental consequences at local and global scales. Managing this pollution is challenging because of diffuse sources and complex relationships between aquatic and atmospheric emissions. We illustrate this for a UK county that has suffered outbreaks of microbial pollution and eutrophication. We surveyed 49 livestock farms covering 12% of total agricultural graz...

Soil and ground water salintty and their relations to physiography
