Fertilizers: Balancing Food Growth and the Environment

Fertilizers supply essential nutrients like nitrogen, phosphorus, and potassium to crops.
Synthetic fertilizers revolutionized farming by boosting yields to feed billions.
Excess fertilizer can wash into rivers, causing algae blooms and dead zones.
Nitrogen fertilizers release nitrous oxide, a powerful greenhouse gas.
Soil chemistry determines how effectively plants absorb added nutrients.
Precision agriculture uses chemistry and data to apply just the right amount.
Organic fertilizers, like compost and manure, release nutrients more slowly and naturally.
Controlled-release fertilizers use coatings to minimize waste and runoff.
Chemistry helps recycle nutrients from food and animal waste back into farmlands.
Balancing fertilizer use is key to feeding people while protecting the planet.
