" On Summoner's Rift, the drop rate for souls from small minions is 33%. However, the probability adjusts dynamically. If you are above or below your expected quota of soul drops from small minions, the probability lowers or rises by a small amount until you are back at your quota of drops "

10 minutes: 108 (caster + melee) + 6 (cannon) = ~36 + 6 = 42 souls

20 minutes: 238 + 12 = ~79 + 12 = 91 souls

30 minutes: 351 + 19 = ~123 + 19 = 142 souls

Without counting the souls from champs and pets.
