Many factors are driving interest in improving soil health in potato production systems in the U.S. Pacific Northwest and beyond, including the need for enhanced sustainability and economic viability, and consumer preferences. Potato production poses a particular challenge in terms of soil health due to intensive tillage, minimal residue left on fields, short rotations, and the importance of managing soilborne pathogens. This review discusses existing soil health assessment methods and their relevance for the region and summarizes results of studies conducted in the Pacific Northwest and beyond, examining practices aimed at improving soil health and their effects on soil health, soilborne pathogens, yield and quality of potatoes, and net returns in potato production systems. These practices include reducing tillage; adjusting crop rotation length and species composition; reducing fumigation; and using cover crops, green manures, and organic amendments.

改善西北太平洋马铃薯生产中的土壤健康：综述

许多因素正在推动人们对改善美国西北太平洋及其他地区马铃薯生产系统中土壤健康的兴趣，包括对增强可持续性和经济生存能力的需求以及消费者的偏好。由于集约耕作，田地上残留的残留物很少，轮作时间短以及处理土壤传播的病原体的重要性，马铃薯的生产对土壤健康构成了特殊的挑战。这篇评论讨论了现有的土壤健康评估方法及其与该地区的相关性，并总结了在西北太平洋及其他地区进行的研究结果，研究了旨在改善土壤健康及其对土壤健康，土壤传播病原体，马铃薯产量和质量的影响的实践，和马铃薯生产系统的净回报。这些做法包括减少耕作；调整作物轮作长度和物种组成；减少熏蒸；并使用农作物，绿肥和有机改良剂。
