Kan. Stat. § 2-1332
In the event the weed supervisor enters or causes entry upon land to control any noxious weed infestation, after service of legal notice, such supervisor shall immediately, after completion of the control operation, notify or cause to be notified, by certified mail, the owner of such land with an itemized statement of the costs of treatment. Such costs of treatment shall include the total cost of chemical materials, labor and use of equipment. Such statement shall include a penalty charge of 10% of the total amount of treatment costs. The unpaid balance of any such treatment costs including such penalty charge shall draw interest from the date of treatment at the rate prescribed for delinquent taxes pursuant to K.S.A. 79-2004, and amendments thereto. A copy of such statement, together with proof of notification, shall at the same time be filed with the register of deeds in such county and the county clerk, and if such amount is not paid within 30 days from the date of mailing of such notice, the county clerk shall record the amount of such statement upon the tax roll prepared by such county 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, except that not more than 25% of the cost of treating the portion of the entire contiguous tract of land so treated, as described and defined in the legal notice as provided in K.S.A. 2-1331, and amendments thereto, shall be recorded on the tax rolls against such land in any one year. The board of county commissioners may, after discussion with the landowner in question, develop a payment plan for the payment of the full amount of the lien over time. If, for any reason, the landowner should fail to fulfill the terms of such agreement, the board of county commissioners may collect the remainder of the amount owed as provided in K.S.A. 2-1320, and amendments thereto. All moneys collected through a payment plan shall be deposited with the county treasurer for credit to the county 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.
