Fertiliser bag weight: how to save it on your phone, bag by bag
Quick answer
You can save each fertiliser bag weight on an Android phone by weighing the bag on a stamped Bluetooth scale that sends the reading to an app. The app keeps bills and report history [1], so nobody copies the display onto a slip and types it in later.
On 11 November 2026 the Union Cabinet approved Nutrient Based Subsidy rates for phosphatic and potassic (P&K) fertilisers for rabi 2026-27, covering 1 October 2026 to 31 March 2027 [4, 5]. The release put the tentative budget requirement at about ₹62,370.02 crore, against ₹37,952.29 crore for rabi 2025-26 [4]. Moneycontrol reported on 11 November 2026 that the Centre would keep di-ammonium phosphate (DAP) at ₹1,350 a bag [5], the price per 50 kg bag that the government supported for kharif 2026 [6].
How do you save a fertiliser bag weight on your phone?
On an HSCo PLCHQBT platform scale the steps are these.
- Switch the scale on with the platform empty and press ZERO [1].
- Open the HSCo BT Bluetooth Smart Weighing Scale app on the Android phone and connect it to the scale [1]. Test the connection with the phone where you will stand while weighing.
- If you use a pallet or crate, put it on the empty platform and press TARE [1]. Keep the same pallet or crate on the platform for the whole lot. Each reading then includes the bag’s own sack.
- Place one bag flat in the middle of the platform and wait until the reading stops changing.
- Record the reading in the app. It goes into the report history [1].
- When the lot is done, open the report history and look for bags that read light. Each reading includes the sack, so a light reading tells you which bags to raise with the supplier, not exactly how much fertiliser is missing.
What does a short fertiliser bag cost?
At ₹1,350 for a 50 kg bag of DAP [5, 6], every kilogram is worth ₹27. A shortfall of a few hundred grams is hard to see on one bag. On a lot of 200 bags with a nominal net content of 10 tonnes, 200 g short a bag adds up to 40 kg.
Value of the shortfall = grams short per bag × number of bags ÷ 1,000 × ₹27 per kg
| Short per bag | Short on 200 bags | Value at ₹27 a kg |
|---|---|---|
| 100 g | 20 kg | ₹540 |
| 200 g | 40 kg | ₹1,080 |
| 500 g | 100 kg | ₹2,700 |
A lot that is 40 kg short is four-fifths of a bag short. The bag-by-bag readings, which include each sack, show which bags to raise with the supplier first.
Why not copy the weight from the display by hand?
Suppose a bag reads 49.85 kg and the slip says 48.95 kg. The register now shows that bag 900 g lighter than it was, worth ₹24.30 at ₹27 a kg. Once the next bag is on the scale, the display reading is gone.
For a register where nobody can type a weight at all, HSCo licenses a customised Android app, HSCo Scale. Every stored weight in it comes from the scale, and a wrong entry is cancelled with a reason and stays visible [7]. It runs with HSCo Bluetooth platform and bench scales of about 30 kg to 3 tonnes [7].
Does a scale that sends weights to a phone still need stamping?
Yes. Under section 24 of the Legal Metrology Act, 2009, anyone who uses a weighing scale in a transaction must have it verified before putting it into use [10]. The PLCHQBT comes stamped by the Legal Metrology department [1], and every new HSCo scale ships with one year of stamping, with the renewal date on its certificate [8].
Which HSCo Bluetooth scale suits a fertiliser godown?
All three scales below send weights over Bluetooth to an Android app and are stamped by the Legal Metrology department [1, 2, 3]. Pick by how you handle the bags.
PLCHQBT Bluetooth platform scale: an MS chequered-plate platform in capacities from 50 to 1,000 kg, with a jumbo green display in front and a big green display at the back. Weights go to the HSCo BT Bluetooth Smart Weighing Scale app [1]. For bags laid flat at the godown door.

Frequently asked questions
How much does a bag of DAP fertiliser weigh?
The government supported a DAP (di-ammonium phosphate) price of ₹1,350 per 50 kg bag for kharif 2026 [6]. That 50 kg is the declared net content, without the sack, so check the net quantity printed on each bag. Moneycontrol reported on 11 November 2026 that the Centre would keep DAP at ₹1,350 a bag [5]. At ₹27 a kilogram, a bag 200 g short is worth ₹5.40 less.
Does a Bluetooth weighing scale app need the internet?
The Bluetooth link between a weighing scale and a phone is a direct radio link and does not use the internet. HSCo Scale, the customised register app HSCo licenses for its Bluetooth platform and bench scales, works fully offline, without sending records anywhere [7]. It gives the day sheet as a PDF and the records as a spreadsheet when you need to share them [7].
How often must a fertiliser godown scale be stamped again?
Under Rule 27 of the Legal Metrology (General) Rules, 2011, an electronic weighing scale used in trade must be re-verified and stamped every 12 months [9]. A scale that is repaired before its verification falls due must be re-verified and stamped before it is used again [9]. Every new HSCo scale ships with one year of Legal Metrology stamping, and the stamping certificate gives the date before which the renewal has to be done [8].
Which scale capacity suits 50 kg fertiliser bags?
A 100 kg scale weighs one 50 kg fertiliser bag with room to spare, as long as the capacity covers the full load, including the sack and any pallet or crate. The PLCHQBT Bluetooth platform scale comes in 50, 100, 150, 250, 300, 500 and 1,000 kg capacities, with accuracy options of 5 g, 10 g, 50 g or 100 g by capacity [1]. The CRSBT Bluetooth hanging scale reads to 10 g on its 100 kg model [2].
