Inspired by an extension event survey comment, Dr. Bijesh Maharjan, associate professor and extension specialist at the University of Nebraska-Lincoln Panhandle Research, Extension and Education Center, conceptualized the soil health cycle (SHC) as an iterative soil health management cycle to achieve agricultural sustainability.

Alfalfa is a tough perennial with established rooting depths down eight feet or more. Depending on deep soil profile moisture, some varieties can extend spring dormancy and survive up to 45 days without rainfall. However, forage yields drop dramatically, since alfalfa requires about six inches of root available water to produce one ton of forage per acre.

An often asked question is, "how much manure do I need?". The answer is not as simple as the question. It depends on the crop you are growing and the expected yield, existing soil nutrients, knowing your goals, the type of manure you wish to use, and any other fertilizer nutrients you expect to apply.

This Nebraska Extension article highlights the impact of factors such as plant genetics and improved production practices to fertilizer consumption in Nebraska over numerous decades.
