By monitoring crops through machine learning and satellite data, Stanford scientists have found farms that till the soil less can increase yields of corn and soybeans and improve the health of the soil – a win-win for meeting growing food needs worldwide.
Research combining future climate conditions and arsenic-induced soil stresses predicts rice yields could decline about 40 percent by 2100, a loss that would impact about 2 billion people dependent on the global crop.
Scientists knew that plants wage chemical war against bacterial, viral and fungal infections. Now they’ve learned how to “vaccinate” tomato plants with a natural chemical to boost their defenses against a pest that makes leaves shrivel up and die.
Some spice processors in Bangladesh use an industrial lead chromate pigment to imbue turmeric with a bright yellow color prized for curries and other traditional dishes, elevating blood lead levels in Bangladeshis.
Overpumping in California’s Central Valley has depleted groundwater storage capacity and caused the land to sink. A new model could help zero in on where water managers can replenish aquifers by flooding fields.
Odds are rising that warm, dry conditions – the kind that can hurt crop yields, destabilize food prices and exacerbate wildfires – will strike multiple regions at once. A new Stanford study shows just how much the risk is increasing.
