Carbon Loss Proportional to Tillage Intensity

Soil scientist Don Reicosky says the more soil you disturb in tillage, the more CO2 is released. In addition, he says tillage is detrimental to fungi-to-bacteria ratios that are vital to carbon and nitrogen storage.

Terminating a Verbal Farm Land Lease

Some farm leases are not written, but are verbal or "handshake" agreements. Because nothing is in writing, the parties may have different recollections of their agreement, making lease disputes more difficult to resolve. The most common legal issue associated with verbal farm leases is how a lease may legally be terminated. Find out more about how to handle this sticky situation in this article from University of Nebraska Extension.

Site-Specific Estimation of Corn Yield Response to Nitrogen Fertilizer

Site-specific yield estimation is important for efficient management of agricultural inputs and explaining spatial yield variability. However, the causes of yield variability may differ due to interactions among weather, crop management, and site characteristics such as soil type and topography, according to the University of Minnesota.

Soil Pore Structure May be Key to Carbon Storage

Scientists have traditionally believed soil aggregates — clusters of soil particles — were the principal locations for stable carbon storage. Recent research from Michigan State University, however, shows that most stable carbon appears to be the result of microbes producing organic compounds that are then adsorbed onto soil mineral particles.

Managing Weeds in a No-Till System

A primary principle in no-till farming is that tillage dramatically disturbs the soil, decreasing water infiltration capacity and increasing the likelihood of erosion, and yet many farmers continue to use tillage to deal with weeds that would otherwise hamper crop production in their fields. A no-till system offers techniques for killing weeds which do not destroy the structure of the soil the way tillage does.
