UK Farmers Battle Scorching Heat with Apple 'Sunscreen'

Farmers across parts of England are using a clay-based substance, mixed with water, to protect apples from severe heat damage. This horticultural kaolin clay solution forms a white film on the fruit, reflecting UV radiation and reducing surface temperatures, effectively acting as a sunscreen. Without this protection, apples can 'boil in their own juice' at temperatures above 30 degrees Celsius, rendering them unsaleable.

This protective measure comes as England faces drought conditions, declared across half of the country. The extreme heat has stressed apple trees, leading to reduced yields. Farmers are also struggling with livestock, forced to feed cows their winter hay supply as grass fails to grow.

The UK has already experienced record-breaking temperatures this summer, with highs reaching 35.1C in May and 38C in June. This has prompted an amber heat warning across southern England and the East Midlands, with London expecting temperatures around 33C. The Environment Agency highlighted that water is being used faster than it can be replenished.

Concerns are mounting over potential food shortages if the warm and dry conditions persist. Crop yields for oats and wheat have been poor, and farmers warn that without irrigation, which is often not financially viable, many more crops could be lost. Heat stress is already estimated to cost UK agriculture £205 million annually.
