Pivot Bio rakes in $430M round D as modified microbes prove their worth in agriculture



Pivot Bio makes fertilizer — but not directly. Its modified microorganisms are added to soil and they product nitrogen that would otherwise have had to be trucked in and dumped there. This biotech-powered approach can save farmers money and time and ultimately may be easier on the environment — a huge opportunity that investors have plowed $430 million into in the company’s latest funding round.

Nitrogen is among the nutrients crops need to survive and thrive, and it’s only by dumping fertilizer on the soil and mixing it in that farmers can keep growing at today’s rates. But in some ways we’re still doing what our forebears did generations ago.

“Fertilizer changed agriculture — it’s what made so much of the last century possible. But it’s not a perfect way to get nutrients to crops,” said Karsten Temme, CEO and co-founder of Pivot Bio. He pointed out the simple fact that distributing fertilizer over a thousand — let alone ten thousand or more — acres of farmland is an immense mechanical and logistical challenge, involving many people, heavy machinery, and valuable time.

Not to mention the risk that a heavy rain might carry off a lot of the fertilizer before it’s absorbed and used, and the huge contributions of greenhouse gases the fertilizing process produces. (The microbe approach seems to be considerably better for the environment.)

Yet the reason we do this in the first place is essentially to imitate the work of microbes that live in the soil (Read more...)
