TN 190-PM-5 - ECS-Plant Materials Program – Using the Appropriate Legume Inoculant for Conservation Plantings
Technical Notes: 190-PM-5 Date: July 13, 2021
Subject: ECS-Plant Materials Program – Using the Appropriate Legume Inoculant for Conservation Plantings.


 
Purpose.  To distribute technical note, Title 190, Plant Materials (PM), Technical Note 05, “Using the Appropriate Legume Inoculant for Conservation Plantings.”
 
Effective Date.  Effective upon receipt.
 
Background.  Legumes are an important component in many conservation plantings. Choosing the appropriate legume inoculant is essential to realize the benefits of including legumes in conservation seed mixes.
 

Explanation.  Vegetative conservation practices, including Conservation Cover (327), Conservation Crop Rotation (328), Cover Crop (340), Critical Area Planting (342), Wildlife Habitat Planting (420), Pasture and Hay Planting (512), and Range Planting (550), often include legumes in the seed mix to provide benefits to other species in the mix, subsequent crops, and to add species diversity. It is important to select the appropriate species of rhizobia for the species of legume being planted, as well as to inoculate and plant the legume seed properly to optimize the colonization of rhizobia on the legume roots. This document provides information on choosing and using inoculants for legume species in conservation plantings.

Distribution. This directive is available on the NRCS Electronic Directives System website at http://directives.sc.egov.usda.gov/.

Filing Instructions. The availability of this information is limited to electronic format. States are recommended to file this document or provide a link to it in their State Field Office Technical Guide (FOTG). If a paper copy is retained, file it sequentially within Title 190, Ecological Sciences, of the Technical Note binder.
