Researchers found that models using soil moisture explain 30-120% more year-to-year variation in yield than those relying on rainfall, revealing a critical link between temperature and water supply for crops. Extreme heat is less damaging to crop yields than previously estimated, while drought and flooding sensitivity increases.

Crop disruption from war in Ukraine could increase global carbon emissions, food prices

A new study predicts that the disruption of crop production in Ukraine due to the Russian invasion will lead to increased global carbon emissions and food prices. However, other countries are stepping up their production to compensate for the loss, which may alleviate food insecurity but with significant environmental impacts.

Agricultural organic amendments may hold the key to conserve soil productivity while alleviate non-point source pollution of intensified hillslope cropping

Crop residue and pig manure slow down nitrogen release compared to synthetic fertilizer, reducing nitrogen loss through synchronized nutrient release and crop demand. Substituting up to 40% synthetic nitrogen with organic amendments can maintain high crop yield and significantly reduce nitrogen loss from sloping cropland.

Weedy rice has become herbicide resistant through rapid evolution

Scientists found that weedy rice has developed herbicide resistance through gene flow from crop rice, with most fields showing resistant plants within 20 years of herbicide-resistant rice cultivation. This rapid evolution is due to the close proximity of weedy and crop rice in the same fields, allowing for pollen transfer and outcrossing.
