Practical knowledge is an abstract concept, relating to how much experience a nation has in the particular field. For Theoretical levels, this is one tech every two months which means you will need two tech slots or so depending on your research modifiers. For Practical levels this can be done by building units and engaging in combat. Therefore, in order to maintain a Knowledge level of at least 20 (the maximum bonus), you will need to increase that Knowledge level by about 0.5 every month.
All Knowledge levels decrease by 2.5% every month.
