Input stock and usage

Input stock records identify an agricultural input, its lot number, unit, quantity on hand and expiry date. Usage records carry a quantity and application date, linked to both an input lot and a field task. That link lets the stock controller answer which approved work consumed a lot and gives the manager a way to compare field work with remaining stock.

When a grower records feeding or another input-consuming activity, the task context matters. A quantity entered against the wrong task can make both the cycle history and the lot balance misleading. Work through the task first, then choose the specific lot used. The operating team should retain the same unit in the lot and use records rather than silently converting between measures.

• Maintain lots. Record the input name, lot number, unit, on-hand quantity and expiry.
• Link use. Attach each applied quantity to a field task and the actual stock lot.
• Reconcile. Compare consumption against the available quantity before the next task uses the lot.

The approval of field work is an important checkpoint for input usage. The manager reviews the task, field and cycle; the stock controller checks lot identity, expiry and quantity. A dated usage record then becomes evidence of consumption against that task.

Decide how units are written and who may correct a lot’s on-hand quantity. Agree how operators identify the lot at the point of application, especially if the same input name appears on several stock rows. Define whether use is recorded at the time of application or during an end-of-day review. Both approaches need the actual applied date and task link.

The team should also decide how to handle a partially used lot near expiry. The stock controller can view lots by expiry date, but a date on a record is not a substitute for physical stock checks. Reconcile imported starting quantities before opening input use to the team.

A manager approves a feeding task for a growing crop cycle. The stock controller finds a lot with the expected input name and a usable expiry date, then confirms that the planned quantity fits the recorded balance in the same unit. After application, the grower gives the controller the task and lot used. The controller records the input use with the applied date and quantity and checks the remaining stock. A manager can later follow the task back to the cycle and field.

Rehearse a second application that would exceed the remaining lot quantity. The controller should resolve the stock discrepancy or select a different verified lot before recording consumption. Keep the first application’s task and lot link intact so the history remains understandable.

• Expired input lots — Check lots whose expiry date has arrived before another use.
• Approved and active field work — Locate work that may need an input record.
• Field work board — Find the assigned task behind an application.
