USDA Natural Resources Conservation Service wants public comments on proposed changes by February 6.

The USDA Natural Resources Conservation Service, or NRCS, in Iowa is accepting public comments until February 6 for its updated nutrient management standard, commonly referred to as the 590 standard. Landowners and operators implementing nutrient management plans or constructing animal waste storage structures must follow the 590 conservation practice standard to receive voluntary conservation program funds. The 590 standard only applies to farmers who enroll in NRCS programs involving nutrient management.

WHAT DO YOU THINK? NRCS is accepting public comments on its updated 590 standard until February 6. Landowners and farm operators implementing nutrient management plans or building animal waste storage structures must follow the "590 standard" to receive conservation program cost-share funding.

The NRCS conservation practice standards are revised every five years to account for new information and technologies. To read the updated 590 standard and provide comments, visit the NRCS website.

New additions to the 590 standard include:

* Incorporation of the 4R's nutrient decisions: apply the Right nutrient source at the Right amount at the Right time in the Right place.

* Fall applications of nutrients with high ammonium content should wait until soil temperatures are 50 degrees F and trending colder.

* Rescue nitrogen application is allowed when nitrogen is lost due to weather conditions.

* Tile inlets are added to sensitive areas to be protected when applying nutrients.

* Manure testing must be done by certified labs.
