WHB/4/8

Sponsored by Ashley Kalvala, Savannah Poynter of Ravenwood High School

This legislation was filed in the Agriculture category

Presented as part of the YIG Volunteer 2024 conference

1 Be it enacted by the Tennessee YMCA Youth Legislature:
2
3 Section 1: Terms in this act are defined as follows:
4 a.) Rain Garden: A rain garden is a depressed area in the landscape that collects rain water
5 designed to increase rain runoff reabsorption by the soil.
6 b.) Peak Season: Period of the year during which growing conditions, like temperature and
7 moisture, are most favorable for cultivation of crops.(July, August, and September).
8 c.) Fertilizer Runoff: the displacement of fertilizer components, via rainwater and mechanical
9 irrigation, from their intended use
10 d.) Conservative Fertilization Techniques: Using fertilizers sparingly only at the rate the plants
11 absorb it.
12 e.) Tilling: The agricultural preparation of soil by mechanical agitation of various types, such as
13 digging, stirring, and overturning which accelerates surface runoff and soil erosion.
14 f.) Groundwater: Water that exists underground in saturated zones beneath the land surface.
15
16 Section 2: Accounting for the fact that fertilizer runoff into groundwater in Tennessee is
17 significantly decreasing water quality and harming biodiversity and within the area. Fertilizer runoff
18 impairs nearly 3,000 river/stream miles and more than 15,000 acres of lakes and reservoirs in
19 Tennessee.
20
21 Section 3: Selected farms as defined in this act will be subject to implementation of runoff
22 filtration techniques such as the implementation of rain gardens, the use of conservative
23 fertilization techniques, and the minimization of tilling within the soil. Larger farms selected, which
24 have an average size of 1,421 acres, will be subject to construction of rain gardens, while smaller
25 farms, with an average size of 231 acres, will be subject to minimal till farming and conservative
26 fertilization techniques. This is due to the fact that minimal till farming and conservative
27 fertilization techniques are less efficient on a larger scale because of the effects they have on
28 yields.
29
30 Section 4: This bill will start off on a smaller scale, starting with only 6,000 farms as a trial to see
31 how effective these methods are in minimizing fertilizer pollution in the waters of Tennessee. The
32 farms selected will be farms within a close vicinity of major water sources that are suspected to
33 cause the most pollution.
34
35 Section 5: Selected farms in Tennessee will undergo the process of putting in place these solutions
36 over a three month period. Over this three month period, the rain gardens will be planted and
37
38 Section 6: The farms that are subject to these solutions will be more likely to receive loans and
39 once these techniques are implemented they will be provided with additional resources for their
40 farms.
41
42 Section 7: 200 workers will be hired to contribute to the construction of rain gardens for 2,000
43 large farms over this three month period. There will be one rain garden planted per farm. It takes
44 2 days and 4 workers to build a single rain garden.
45
46 Section 8: 4,000 farms with an average size of 231 acres will be subject to minimal till agricultural
47 practices and use of conservative fertilization techniques. Agriculture experts will be sent to these
48 farms to educate farmers on these techniques.
49
50 Section 9: This implementation will start on a small scale and after a year long period we will
51 measure its success at limiting chemical runoff from fertilizers utilized by farms across Tennessee.
52 If the implementation shows a progression in biodiversity and water quality we will ask to
53 implement these techniques on a larger scale. Implementation on a larger scale would be utilizing
54 these techniques on additional farms.
55
56 Section 10: This bill will have a cost of 5.5 million dollars to cover the costs including 2 million for
57 the construction of rain gardens, 1.5 million to pay the workers to install the rain gardens, and 2
58 million for the additional resources provided to the farms. This will be funded through the
59 Tennessee Department of Agriculture.
60
61 Section 11: All laws or parts of laws in conflict with this are hereby repealed.
62
63 Section 12: This act shall take effect March 1st 2025, to provide ample conditions for workers
64 involved in these resolves, and to ensure that farmland is ready for peak season.
