Scientific research provides critical insights into how uranium affects agriculture. For example, Mordberg et al. found that high 238U levels in soil reduce crop yields by inhibiting corn growth and decreasing overall yields due to the toxicity of the radionuclide to root systems. Similarly, barley grown on contaminated soil exhibited a notable decline in biomass and grain production, underscoring the harmful impact of uranium on crop health. Plants accumulate uranium at different rates throughout their growth stages, with oats and barley showing the highest levels of accumulation. Kasianenko et al. further explored the movement of uranium in soil and plants, revealing that increased uranium levels in the soil negatively affect plant growth, resulting in smaller crops and cellular damage.

The chemical toxicity of DU is particularly concerning. Asic et al. highlight that DU particles, once introduced into the environment, can persist for long periods, contaminating soil and water, which are essential for agriculture. This prolonged contamination can lead to higher uranium absorption by plants and animals, disrupting food chains and harming biodiversity. DU’s dual nature as both chemically toxic and radioactive poses long-term risks to ecosystems.
