Although nitrogen is one of the most essential nutrients for plants, it’s also among the most expensive inputs on no-tillers’ ledgers and the subject of long-running debates on what form is most efficient and cost-effective. But John Kempf says many of these questions can be answered by understanding the rhizophagy cycle and using that knowledge to manage nutrients in a way that improves crop health and profits while increasing resilience to weather stress.

The founder of Advancing Eco Agriculture will discuss how plants absorb and utilize different forms of nitrogen, how some forms of nitrogen increase a plant’s water requirements, how to greatly increase nitrogen use efficiency and reduce application rates. He’ll also describe how plants absorb microbes directly from the soil, how to get the greatest benefit from seed treatments, and how to use other nutrients to get the same growth energy that nitrogen delivers — but with much higher quality.
