धान्यस्नेहक्षारलवणानां धान्यकल्पं सीताध्यक्षे वक्ष्यामः ॥ कZ_०२.१५.१२ ॥
dhānya-sneha-kṣāra-lavaṇānāṃ dhānya-kalpaṃ sītādhyakṣe vakṣyāmaḥ.
The procedures (kalpa) for grain, oils/fats, alkaline products, and salts—on the grain model—will be explained under the Superintendent of Agriculture (Sītādhyakṣa).
Because their production and primary control are tied to agriculture and state-managed cultivation/supply chains, so rules are centralized there.
A template approach: apply the same accounting/handling logic used for grain to related staples (oils, salts, alkaline products).
