Soil management practice affects the ability of biostimulants to improve the quality of fresh produce, bringing added value to consumers. It is hypothesised that the biostimulants effects on soil structure, nutrient content and availability, root morphology, plant physiology, and soil/plant symbiotic relationships are explanatory mechanisms (Halpern et al., 2015).This project will have 3 phases:1. Multifactorial analysis to select: a) biostimulant treatments (and modes of application), b) the salient indicators of soil health (physical, chemical and biological properties), c) target crops / produce (e.g. salad or vegetables) and d) crop quality indicators (e.g. selected nutrients, vitamins, antioxidants). 2. Evaluate the effects of biostimulant application, in terms of crop quantity and quality, using 2 complementary approaches: a) soils and fresh produce grown on the long term Saxmundham site, Rothamsted Research (Broadwalk field) and growers fields with a long and/or known history of known biostimulant application will be sampled to test the hypothesis that biostimulant treatments affect soil structure, nutrient content and availability, root morphology, plant physiology, and soil/plant symbiotic relationships, leading to differences in crop quality (levels of vitamins, nutrients and antioxidants). b) The unique Soil Health Facilities at Cranfield University will be used to control environmental variables (temperature, light, rainfall) to improve the signal to noise ratio often found from field experimental data. This will allow better understanding of how biostimulant effectiveness changes with soil management practice (e.g. biostimulant type, mode of application). 3. The students placement at Sainsburys will investigate the consumer facing impact and value from fresh produce grown on better managed soils. For example, are nutritional benefits meaningful within a consumer diet? How does nutritional content impact on product shelf life (potentially reducing food waste)? Are the benefits of using a more circular economy regarding organic resources understood and valued by growers / suppliers / retailers? What regulations apply?

土壤管理实践影响到生物刺激剂提高生鲜农产品质量的能力，为消费者带来附加值。假设生物刺激剂对土壤结构、养分含量和有效性、根形态、植物生理和土壤/植物共生关系的影响是可解释的机制(Halpern等人，2015)。该项目将有3个阶段：1.多因素分析以选择：a)生物刺激剂处理(和应用模式)，b)土壤健康的显著指标(物理、化学和生物特性)，c)目标作物/农产品(例如沙拉或蔬菜)和d)作物质量指标(例如选定的营养物质、维生素、抗氧化剂)。2.使用两种互补的方法，从作物数量和质量的角度评估生物刺激剂的应用效果：a)长期生长在萨克斯蒙德姆试验场、Rothamsted Research(布罗德沃克田地)和种植者田地上的土壤和新鲜农产品将被抽样，以检验生物刺激剂处理影响土壤结构、养分含量和有效性、根系形态、植物生理和土壤/植物共生关系，从而导致作物质量(维生素、养分和抗氧化剂水平)差异的假设。B)克兰菲尔德大学独特的土壤健康设施将被用来控制环境变量(温度、光线、降雨量)，以改善通常从田间实验数据中发现的信噪比。这将有助于更好地了解生物刺激剂的有效性如何随土壤管理实践而变化(例如，生物刺激剂的类型、使用方式)。3.Sainsburys的学生安置将调查消费者面临的来自管理更好的土壤上种植的新鲜农产品的影响和价值。例如，消费者饮食中的营养益处有意义吗？营养成分如何影响产品的保质期(潜在地减少食物浪费)？种植者/供应商/零售商是否了解和重视对有机资源使用更循环经济的好处？适用哪些规定？
