This Small Business Innovation Research (SBIR) Phase I project seeks to develop novel soil organic matter (SOM) amendment techniques focused on improving nutrient supply to crops, sustaining agriculture, and providing long-term, deep soil carbon sequestration to help combat climate change. New methods of developing persistent organic matter amendments in soil are urgently needed in the US and globally. The result of this work will be to introduce new soil fertility and carbon storage services that permanently sequester carbon in agricultural soils at an unprecedented rate. The approach is synergistic with other economic co-benefits, such as increasing crop yields, reducing fertilizer loads, reducing atmospheric carbon dioxide (CO2) concentrations as related to farming, and expanding biorefineries and forest management capabilities. These high-quality agricultural soil amendment services may eventually have a positive impact on the global environment. This project seeks to develop a novel, soil organic matter amendment technique. The research and development will enable acquisition of critical benchmarking and verification data. Critical prototyping, initial verification, and benchmarking in a representative agricultural soil will be conducted so that the technique can then later be extended to other farms. This proposal seeks to: 1) demonstrate viable integration into operations on commercial farms, 2) demonstrate that the method is scalable to fields and acre-scale applications, and 3) perform initial stability tests to verify the carbon is chemically stabilized using in situ CO2 gas analyzers, 4) track carbon content changes, 5) perform laboratory experiments compared against controls to verify it is not vulnerable to oxygen exposure from root intrusion, and 4) validate soil fertility improvements including changes in soil properties like soil water-holding capacity, cation exchange capacity, and base saturation. The project will use field- and lab-incubated biweekly CO2 loss rates to estimate the mean residence time (MRT) of carbon and compare treatment plots against controls. The results will be validated with random field locations and control plots of land.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该小企业创新研究 (SBIR) 第一阶段项目旨在开发新型土壤有机质 (SOM) 改良技术，重点是改善农作物的养分供应、维持农业并提供长期、深层的土壤固碳以帮助应对气候变化。美国和全球迫切需要开发土壤中持久性有机物改良剂的新方法。这项工作的结果将是引入新的土壤肥力和碳储存服务，以前所未有的速度在农业土壤中永久封存碳。该方法与其他经济协同效益具有协同效应，例如提高作物产量、减少化肥负荷、降低与农业相关的大气二氧化碳 (CO2) 浓度，以及扩大生物精炼厂和森林管理能力。这些高质量的农业土壤改良服务最终可能对全球环境产生积极影响。该项目旨在开发一种新颖的土壤有机质改良技术。研究和开发将能够获取关键的基准测试和验证数据。 将在具有代表性的农业土壤中进行关键原型设计、初步验证和基准测试，以便随后将该技术推广到其他农场。 该提案旨在：1) 证明可行地融入商业农场的运营，2) 证明该方法可扩展到田地和英亩规模的应用，以及 3) 进行初始稳定性测试，以验证使用原位二氧化碳对碳进行化学稳定。气体分析仪，4) 跟踪碳含量变化，5) 与对照进行实验室实验比较，以验证其不易受到根部侵入引起的氧气暴露的影响，4) 验证土壤肥力的改善，包括土壤持水性等土壤特性的变化容量、阳离子交换容量和碱饱和度。该项目将使用现场和实验室孵化的每两周二氧化碳损失率来估计碳的平均停留时间（MRT），并将处理区与对照区进行比较。 结果将通过随机实地位置和控制土地进行验证。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
