Beyond the harvest: England’s potato growers face a critical winter water test

The recent drought update highlights the urgent need for England’s potato industry to focus on replenishing irrigation reservoirs, as many are only 0-20% full. A temporary regulatory measure allows some growers to refill outside typical periods but requires compliance with environmental protections. The situation emphasizes the importance of water management for future production, stressing that separate assessments of past yields and future resource availability are crucial for planning.

Assessing the autumn potato crop: Germany’s harvest outlook depends on both production volume and marketable quality

Germany anticipates a significantly reduced potato harvest of about 10.4 million tonnes in 2026, down from 13.9 million tonnes in 2025. Weather factors and decreased planting area have influenced this decline. Industry representatives emphasize that while production is lower, it does not necessarily mean supply shortages due to existing demand, storage conditions, and market specifics. Further assessments will clarify how the crop meets market needs throughout the season.

More than calories: Can an iron-rich potato change a family’s health?

Peru is moving two conventionally bred, iron-rich potato varieties into certified seed production after decades of research. The science is promising: a controlled trial found that meals made from an iron-biofortified potato delivered substantially more absorbed iron than a conventional comparison. Yet breeding is only the beginning. Seed availability, farmer confidence, culinary acceptance, affordability and public-health coordination will determine whether a better tuber becomes measurably better nutrition for Andean families.

Beyond the congress hall: Will Kenya 2026 leave a lasting potato legacy?

From 26 to 30 October, the World Potato Congress will meet in Kenya—the first edition held in sub-Saharan Africa. Delegates from 62 countries are already registered, but the event’s significance extends beyond attendance figures. Its lasting value will depend on whether global science, investment and technology connect with farmers’ everyday constraints, and whether African growers, researchers, young people and businesses help set the agenda rather than merely host it there.

Salt in the root zone: An emerging test for global potato production

Soil salinity is quietly reducing potato performance in irrigated and coastal production regions, often before obvious symptoms appear. New research suggests that zinc and phosphorus may help certain potato genotypes withstand salt stress, but it is not yet a field-ready prescription. The larger lesson is practical: test water and soil, understand where salts accumulate, protect drainage and match varieties and nutrients to the root-zone problem before yields begin to disappear.

Less nitrogen, but the same crop?

A Prince Edward Island field study found that reducing potato nitrogen applications by 25% preserved marketable yield while some combinations of rotation and enhanced-efficiency fertiliser sharply lowered nitrous oxide emissions. The result is promising, but it is not a universal recommendation to cut rates. It demonstrates why nitrogen decisions should reflect soil supply, rotation history, weather, variety and requirements—and why measuring the crop matters more than following a habitual number.

How cold chain logistics helps reduce waste in fresh and frozen potato distribution

Potatoes are vital to global food supply, yet significant amounts spoil before reaching consumers due to inadequate cold chain logistics. Effective temperature and humidity control from harvest to storage is crucial to minimize degradation and sprouting. Cold storage and consistent monitoring throughout transportation prevent quality loss. Implementing efficient cold chain practices reduces waste, benefiting both profitability and sustainability, while enhancing potato supply chain resilience for manufacturers and distributors.

What the canopy cannot tell us: Heat damage hidden inside the potato ridge

Recent potato losses in East Asia due to extreme heat highlight significant production risks. South Korean grower Lee Sang-hyuk discovered that potatoes, seemingly healthy above ground, were damaged beneath the surface during a heatwave. The temperatures disrupt tuber formation, impacting yield and quality. The findings emphasize that managing soil temperature and moisture is crucial, as traditional measurements may not reflect the conditions tubers experience, leading to hidden crop losses.

Holding the ground: Why soil retention is becoming a potato production priority

Potato production faces significant soil loss due to runoff, wind, and harvesting, which impacts fertility and future yields. A 2025 incident in Somerset highlighted this issue when a grower faced over £40,000 in costs due to soil erosion. Effective soil management strategies include understanding field conditions and using cover crops, but growers often underestimate these losses, which diminish soil quality and agricultural sustainability. Soil retention must be prioritized alongside crop production.

Same variety, different crop: Why seed-tuber age deserves more attention

Physiological age significantly affects seed tuber performance, but current measurement methods for growers are inadequate. Although seed tubers may appear similar, their internal developmental conditions can lead to varying crop outcomes. A 2026 scientific review highlights the lack of fast, reliable tests and suggests that physiological readiness should complement traditional seed quality assessments. The industry must better understand and manage the biological condition of seed for optimal growth.
