Soil diversity is crucial for maintenance of sustainable ecosystems. Soil varies on a continuum from microbial habitats to fields, regions, continents and the globe. This project will take a unifying approach to derive a general spatial scaling theory that will allow us to estimate the likely behaviour of soil properties at all scales. Understanding the scaling behaviour of soil means one can be certain about describing the changes in relationships between soil properties and processes. It will enhance the ability to monitor soil property changes through time, essential for gauging effects of climate change and achieving food security.

土壤多样性对于维持可持续生态系统至关重要。土壤在从微生物栖息地到田地，区域，大陆和地球的连续体中变化。该项目将采用一种统一的方法来得出一般的空间缩放理论，该理论将使我们能够估算所有尺度上土壤特性的可能行为。了解土壤的缩放行为意味着人们可以确定地描述土壤特性与过程之间关系的变化。它将增强随着时间的推移监测土壤财产变化的能力，这对于衡量气候变化的影响并实现粮食安全至关重要。
