By Kyle Broderick

The Plant and Pest Diagnostic Clinic will be working at partial capacity October 12-19 due to my wedding out of state. Plant samples may still be submitted, but turnaround time will be delayed. All samples submitted to the clinic during this time will be stored under refrigerated conditions to maintain quality. I will return to the office October 19. Thanks in advance for your patience.

The following diseases were reported in samples submitted to the UNL Plant and Pest Diagnostic Lab September 27 to October 5, 2017

Video: No-Till vs Tillage: Why Neighboring Fields Are World Apart

“No-till means no yield.”

“No-till soils get too hard.”

But here’s the real story — straight from two fields, same soil, same region, totally different outcomes.

Ray Archuleta of Kiss the Ground and Common Ground Film lays it out simply:

Tillage is intrusive.

No-till can compact — but only when it’s missing living roots.

Cover crops are the difference-maker.

In one field:

No-till + covers ? dark soil, aggregates, biology, higher organic matter, fewer weeds.

In the other:

Heavy tillage + no covers ? starving soil, low diversity, more weeds, fragile structure.

The truth about compaction?

Living plants fix it.

Living roots leak carbon, build aggregates, feed microbes, and rebuild structure — something steel never can.
