Wisconsin legislation would allow lower-nutrient manure-based fertilizer
Legislation introduced in the Wisconsin Assembly would allow the sale of manure-based fertilizer with lower levels of nitrogen, phosphorus, and potassium.
Current law requires fertilizer to have a combined weight of these three active ingredients at least 24% of the total weight. If passed, this would allow more use of compost-based soil or plant additives with less N, P, and K. The bill also relaxes some labeling and field testing requirements now in place for fertilizers.
The bill was introduced by Representative Scott Krug and cosponsored in the Senate by Andre Jacque. It has been referred to the Assembly Agriculture Committee.
