VETOED: Healthy Soils Program

SB2989 is a new bill establishing a Healthy Soils Program that was enrolled to the Governor May 2022. The Healthy Soils Program requires the Department of Agriculture to offer education, technical assistance, and grants to help farmers implement healthy soils practices. $500,000 was appropriated to support this bill. 

The Healthy Soils Program shall:

  • Create a statewide soil health assessment
  • Provide education and technical assistance to farmers
  • Establish healthy soils standards based on the findings of the GHGSTF (created by Act 15) 
  • Provide financial incentives to encourage on-farm healthy soils practices

The Act was set to take effect on July 1, 2022 but was vetoed by the Governor. 

Allowing Composting in Agricultural Districts

legislature recognized the soil health, agricultural, and climate benefits of allowing composting in agricultural districts. 

This bill amended Hawaii’s definition of agriculture to now include composting, as follows:

“Composting and co-composting operations; provided that operations that process their own green waste and do not require permits from the department of health shall use the finished composting product only on the operation’s own premises to minimize the potential spread of invasive species.”

The bill was transmitted from the Hawaii legislature to the Governor May 2022. 

Farmer Apprentice Mentoring Program

SB3197 appropriates $300,000 toward a farmer mentorship program to help new farmers learn soil health best practices from mentor farmers. Since composting is considered a best practice, this program can promote composting and assist with monitoring of newly permitted operations.

This bill was enrolled to the Governor May 2022 and is expected to take effect in July 2022.
