When no-tillers are looking to boost crop yields, it’s tempting to search for the “latest and greatest” product to find the solution. But sometimes farming from a job isn’t the answer. There could be some elusive reasons yields aren’t hitting expectations.

Micronutrients — such as boron, cobalt, copper, iron and molybdenum — only make up about 2% of a typical crop fertility program. But failing to manage them properly can hurt yield potential in a big way. Micros activate enzymes that speed up the engine of nutrient uptake and cycling, control disease, injuries and more, which helps plants meet their full potential. 

Every micronutrient has a specific role it plays in the rhizosphere, whether it’s coming from residue, cover crops, an application or through natural processes. Here’s a rundown of the key micronutrients and what they do for your crops.

The Architect — Silica 

Jim Hoorman, a retired NRCS educator, cover crop expert and owner of Hoorman Soil Health Services in Jenera, Ohio, says this nutrient gets very little mention, but it plays a key role in plant tissues in a way that provides strength, prevents…
