TerraBlaster
TerraBlaster is a California agtech startup building a rugged, tractor-mounted soil sensor that reads nitrogen, phosphorus, potassium, pH and other nutrients in real time using Laser-Induced Breakdown Spectroscopy (LIBS) - the same laser technique NASA uses on Mars rovers, licensed from St. Louis deep-tech firm Impossible Sensing. Led by CEO Jorge Heraud, who previously co-founded Blue River Technology (acquired by John Deere for $305M), the company aims to replace slow, sparse lab soil sampling with instant, plant-level nutrient maps so farmers can apply exactly the right amount of fertilizer - cutting waste, boosting yields, and protecting waterways.
Pivot Bio
Pivot Bio engineers nitrogen-fixing microbes that live on crop roots and feed corn, wheat, sorghum and small grains directly, replacing a portion of synthetic fertilizer with a biological alternative that does not volatilize into the atmosphere or leach into groundwater.
