The waters and soils of our environment contain naturally-occurring organic matter (NOM), which helps to regulate soil fertility, pollutant toxicity, ecosystem behavior and carbon cycling. These in turn affect agricultural production, public and ecosystem health, and global climate change. However, the processes which produce NOM from plant and animal matter are poorly understood, due to the complex nature of NOM and the multitude of possible reactions in the environment. This project will combine the efforts of ecologists, geochemists and computer scientists in an attempt to model this complex system using a novel stochastic approach. In this approach, millions of individual molecules are simulated and reacted together 'in silico' to provide a computer model of the complex natural processes. The model will be developed and tested via an internet collaboration, and ultimately will be accessible to agricultural, environmental and earth scientists via a simple web browser interface.

水体和土壤中含有天然有机物质（NOM），它有助于调节土壤肥力、污染物毒性、生态系统行为和碳循环。这些反过来又影响农业生产、公众和生态系统健康以及全球气候变化。然而，由于NOM的复杂性和环境中可能发生的多种反应，人们对植物和动物物质产生NOM的过程知之甚少。这个项目将结合生态学家、地球化学家和计算机科学家的努力，试图用一种新颖的随机方法来模拟这个复杂的系统。在这种方法中，数以百万计的单个分子被模拟并在“计算机”中一起反应，以提供复杂自然过程的计算机模型。该模型将通过互联网合作开发和测试，最终农业、环境和地球科学家将通过一个简单的网络浏览器界面访问该模型。
