odvodnných

It seems that the term "odvodnných" may be a misspelling. In Czech and Slovak, a likely intended form is "odvodněných," which relates to drainage (odvodnění) or drained conditions. If you want, I can write a concise, neutral wiki-style article about drainage of soils and related topics (definitions, methods, agricultural and environmental significance).

Alternatively, if you meant a financial or legal sense (for example relating to deductions or withholdings), I can draft an article on that meaning as well. Could you please confirm which interpretation you have in mind, or provide a brief definition of the term as you intend? Once clarified, I will produce a concise article under 300 words.
