Kan. Stat. § 2-1320
In case the weed supervisor enters upon land or furnishes weed control materials pursuant to a contract or an agreement with an owner, operator or supervising agent of noxious weed infested land for the control of such noxious weeds and, as a result of such weed control methods, there are any unpaid accounts outstanding by December 31 of each year, the board of county commissioners or governing body of the city shall immediately notify or cause to be notified, such owner with an itemized statement as to the cost of material, labor and use of equipment and further stating that if the amount of such statement is not paid to the county or city treasurer wherein such real estate is located within 30 days from the date of such notice, a penalty charge of 10% of the amount remaining unpaid shall be added to the account and the total amount thereof shall become a lien upon such real estate. The unpaid balance of such account and such penalty charge shall draw interest from the date of entering into such contract at the rate prescribed for delinquent taxes pursuant to K.S.A. 79-2004, and amendments thereto. A copy of the statement, together with proof of notification, shall at the same time be filed with the register of deeds in such county and the county or city clerk, as the case may be, and if such amount is not paid within the next 30 days the county or city clerk, as the case may be, shall spread the amount of such statement upon the tax roll prepared by the clerk and such amount shall become a lien against the entire contiguous tract of land owned by such person or persons of which the portion so treated is all or a part, and shall be collected as other taxes are collected, and all moneys so collected shall be paid into the noxious weed eradication fund or, if the noxious weed program is funded primarily through the county general fund, such moneys shall be paid into the county general fund. If the noxious weed program is funded from more than one source, all moneys collected pursuant to this section shall be paid into each source in proportion to its contribution to the noxious weed program. If any land subject to a lien imposed under this section is sold or transferred, the entire remaining unpaid balance of such account plus any accrued interest and penalties shall become due and payable prior to the sale or transfer of ownership of the property, and upon collection shall be paid to the noxious weed eradication fund or, if the noxious weed program is funded primarily through the county general fund, such moneys shall be paid into the county general fund. If the noxious weed program is funded from more than one source, all moneys collected pursuant to this section shall be paid into each source in proportion to its contribution to the noxious weed program.
