​New Pra​ctices​


50.663 - Conservation cover  
  • SEG Funding
  • Definition: The establishment and maintenance of permanent vegetative cover in an agricultural setting to reduce erosion, improve water quality, and soil health.
  • Best for soil stabilization, water quality improvement, and general wildlife habitat enhancement primarily utilizing introduced grasses, forbs, and legumes
  • What SWRM is covering: 
    • 70% Cost Sharing available to prepare and install an agricultural area not to exceed 20% of the field or up to 12 acres whichever is smaller, into permanent vegetative cover with a county approved ​​ten year maintenance plan in accordance with applicable NRCS Standards
      • 50% Cost Sharing only if the soil and water resource concerns meet minimum planning criteria and the only purpose of the planting​ is to provide wildlife habitat​​
    • Eli​​gible costs: protective fencing, mulch, seed, site preparation
    • ​Ineligible costs: critical area seedings, whole-field conversion, and pasture plantings​
  • Documentation Requirements:
    • County will certify on reimbursement form that a 10-year maintenance plan is in place and all parties have agreed to the maintenance requirements for the practice. 
    • ​Nutrient Management Checklist required for reimbursement
    • County land conservation departments should keep and maintain records like seed tags, and other invoices necessary to show that the practice was seeded down and established appropriately.
    • A printout of the seed mix provided to the producer should be kept in the county record.
  • Considerations for Implementation, Monitoring, and Maintenance:
    • This practice is meant to primarily consist of introduced species of grasses, forbs, and legumes. These are typically considered “cool season” grasses.
    • Ensure that the seed mix used meets site requirements and moisture needs of the plants.
      • Utilize the NRCS Seed Mix Calculator(s) located in Section 3 of the Wisconsin eFOTG ​under Conservation Planning Tools
        • ​There are two calculators – one for custom mixes​ and the other for standard mixes (CRP etc). Refer to the “Mix Criteria” table at the bottom of the spreadsheet for minimum species, seeding rates, etc.
    • Fertilizer may be necessary for these plantings but should be done in accordance with Technical Note 6. 
      • Manure applications are prohibited on these sites.
    • Harvesting is not allowed; however grazing and haying are allowable ​maintenace methods following appropriate standards.
    • Recipient must maintain cover for 10 years.
  • Wisconsin Legislature: ATCP 50.663

  • What SWRM is covering:
    • Flat rate available to design and prepare a plan in accordance with NRCS standards that introduces diversification into a crop rotation with a county approved maintenance plan for a minimum of three​ years or the duration of cost share whichever is longer (SWRM funding is limited to four years)
  • Eligible costs: Diversified crop rotations (cover crops, small grains, perennial crops, livestock integration)
  • Ineligible costsPermanent cover or years following establishment of a perennial crop
  • Rate of Reimbursement: $10 per acre, per year
  • Documentation Requirements:
    • County will certify on reimbursement form that a maintenance plan is in place for the duration of the cost share and all parties have agreed to the maintenance requirements for the practice
    • Nutrient Management Checklist required for reimbursement as it is essential to plan, implement, and verify this practice
    • Keep a copy of records necessary to ensure the changes to the existing rotation are sufficient to improve the resource concern. Records may include SNAP+ files or database, job sheets, implementation requirement sheets, etc.
    • Changes to the rotation during the contract should be documented and verified that they still meet the standard
  • Considerations for Implementation, Monitoring, and Maintenance:
    • Utilize the 2025 NRCS Standard 328 when it becomes available (anticipate​d: October 1, 2025). The standard will be significantly updated to include greater consideration for soil loss and soil health
    • Maintenance is required for the duration of contracted plan
      • At least one planned rotation in no less than three years and no more than four years.​
    • E​​nsure that the rotation meets Tolerable Soil Loss (T), manages runoff, and implements proper nutrient management as part of a system
      • ​For examp​le, a typical corn and soybean rotation with reduced or no-till may be sufficient to meet tolerable soil loss, but not some of the other goals of the practice for which incorporating a third crop like a small grain, cover crop, or perennial cover may.
      • Changing crops alone might not be sufficient to meet resource concerns. Tillage and other management practices may be necessary depending on the goals and planning of this practice.
  • Wisconsin Legislature: ATCP 50.668​​

      • Work with your DATCP Area Engineering contact prior to contracting to make sure your project will meet the definition of hydrologic restoration​.
  • Example Scenario: 
    • ​Existing Condition/Issue: An incised stream channel through a wetland has significantly down-cut, thus disconnecting the channel from the floodplain. During high-flows, the channelized flow increases the potential for erosion, and during low-flows, the incised channel functions as a drainage ditch and drains the wetland.
    • Proposed Project/Solution: By applying a combination of practices, such as channel bed stabilization, streambank protection, wetland restoration, upland soil health practices, and others, we can increase infiltration, slow the flow of surface runoff, raise the channel bed to reconnect the channel with the floodplain and disperse the flow. To the extent possible, by stacking practices, we can return the stream/wetland complex back to a natural and self-regulating condition.

    Additional Considerations​​​


    ​CRP Eligibility

    ​By establishing long-term vegetative practices like Conservation Cover and Habitat Diversification a landowners eligibility for CRP may be impacted. These longer term vegetative practices are not meant to replace the function of CRP but may fit on the farm in areas where CRP might not. 
    ​Conservation Compliance

    ​Farmland Preservation participants are required to maintain compliance with agricultural performance standards. These new practices may be new tools to assist in not only improving the land but ensuring compliance. 
    ​​Soil Health
    ​Soil is a vital living ecosystem that sustains plants, animals, and humans. Soil health is about restoring its capacity to provide five crucial functions: regulating water, sustaining plant and animal life, cycling nutrients, providing physical stability and support, and filtering and buffering potential pollutants.

    Healthy soil systems are created by incorporating five principles: maximizing soil cover (such as cover crops and no-till), maximizing living roots in the soil (through cover crops, diverse crop rotation, and perennial crops), maximizing crop and plant diversity (with cover crops, diverse crop rotation, and perennial crops), integrating livestock (managed grazing and proper manure management), and minimizing soil disturbance (no-till, reducing chemical fertilizers, and reducing pesticides).

    Soils can be broken down into three primary properties: chemical, physical, and biological. Soil health recognizes that soil biology drives most soil functions. Incorporating the five soil health principles creates an environment for soil biology to thrive. Healthy productive soil will be home to about 7-11 billion organisms in just one gram! 

    Utilizing these new, or any, practices for soil health may require additional and careful planning and consideration to ensure successful implementation and long-term benefits.

    For additional information about the five principles of soil health please see: DATCP Home Soil Health (wi.gov)
