Farmer's delight soil + ars nouveau

Does anyone know if the special compost soil accelerate growth of crops like source berries? I assume mageblooms do work, since they are a more "standard" crop that has growth stages, but berries have 3 stages and revert to stage 2 when harvested instead to 0%

Also, if they do speed it up, do those growth ticks count as bone meal and not generate source, or is this process sped up in a way where agronomical source link would yield extra source still?

Thank you in advance!
