Özet

Farming in cold climates faces familiar hurdles: low soil temperatures, poor nutrient availability, and repeated frost damage that depresses yields. One promising ally in these settings is the soil microbiome-especially psychrophilic and psychrotolerant communities that function at or below freezing. These microbes produce cold-active enzymes, antifreeze and cold-shock proteins, and extracellular polysaccharides that keep cells working in frozen soils. They help release and cycle key nutrients (P, N, K), improve seed germination, and bolster plants against cold stress. This chapter examines the physiological, genetic, and biochemical traits that let these organisms-particularly Pseudomonas, Bacillus, Arthrobacter, and Psychrobacter-perform under subzero conditions. It then turns to practice: biopriming, seed coatings, and microbial consortia designed as cold-active biofertilizers and biopesticides. Emerging tools in synthetic biology, metagenomics, and data-driven trait discovery are highlighted for engineering the next wave of inoculants tailored to cold soils. Together, these microbiome-based strategies point to farming systems that are tougher, more resource-efficient, and better adapted to a warming world’s cold regions-supporting the long-term sustainability of agriculture where low temperatures still rule.
