Agricultural calculators for Indian farmers and agronomists. Estimate crop yields based on land area and variety, calculate fertilizer NPK ratios, plan irrigation water requirements, convert between Indian land measurement units, and project farm profitability including MSP (Minimum Support Price) comparisons.

What are Agriculture?
Agriculture tools on SabTools.in handle the field-level math that Indian farmers, agronomists, and agri-entrepreneurs use across a crop cycle — how many kilograms of seed per acre for a given crop, how much fertilizer (urea, DAP, MOP) at the recommended NPK dosage, how many litres of irrigation water to apply given soil type and crop stage, what the land area is when measured in the regional units (bigha, guntha, acre, hectare), what the expected yield is given inputs and soil quality, and what the net profit looks like after input costs, labour, and market-yard charges. These are the calculations that determine whether a Kharif or Rabi crop is profitable before planting and whether the harvested output justified the investment afterwards. Each tool here uses ICAR-recommended defaults for Indian crops (paddy, wheat, cotton, sugarcane, maize, pulses, oilseeds) across major regions (Punjab-Haryana plain, Gangetic UP-Bihar, Telangana-AP rainfed, Maharashtra-Karnataka, Tamil Nadu delta).
Key Features & Capabilities
ICAR-recommended crop-specific seed and fertilizer rates
Seed Rate Calculator takes crop + variety + spacing preferences and returns kg/acre for the recommended density. Fertilizer Calculator takes crop + target yield + soil-test NPK status and returns urea/DAP/MOP quantities to reach the recommended NPK ratio (e.g., paddy at 120:60:40 NPK kg/ha for basmati).
Regional-unit land-area conversion
Land Measurement Converter handles bigha (Punjab 1,600 sq ft; UP 27,000 sq ft; WB 27,225 sq ft — regionally variable), guntha (Maharashtra/Karnataka 1,089 sq ft), kanal (Punjab 5,445 sq ft), cent (Tamil Nadu/Kerala 435 sq ft), and converts to the global standard acre (43,560 sq ft) or hectare (107,639 sq ft) for regulatory filings and crop-insurance claims.
Soil-and-crop-stage-aware irrigation sizing
Irrigation Calculator takes crop + growth stage + soil type (sandy, loamy, clay) + current weather + method (flood, sprinkler, drip); returns litres per day per acre. Drip systems use 40-60% less water than flood; the tool quantifies the savings.
End-to-end crop profit estimation
Farm Profit Calculator builds a profit-loss statement for the crop — seed cost, fertilizer cost, labour (family + hired), irrigation, crop-protection (pesticide/herbicide), harvest, transport to mandi, APMC cess; compared against expected revenue at current MSP or mandi rates. Crop Yield Calculator gives the yield input for this (quintal/acre given inputs and variety).
Common Use Cases
Pre-season crop planning
Before sowing, farmer runs Seed Rate Calculator (for seed quantity), Fertilizer Calculator (for input cost), Irrigation Calculator (for water budget), and Farm Profit Calculator (for projected margin). A negative projected margin is a signal to either change crop or seek better input pricing from the local FPO or co-operative — far better than discovering the loss after harvest.
Land-area verification for sub-division and inheritance
Agricultural families often inherit land measured in the regional unit but registered (in land records) in acres. Land Measurement Converter handles the bigha-to-acre conversion with state-specific multipliers. Critical for sub-division calculations, stamp-duty assessment, and crop-insurance filings which require hectare-denominated areas.
Crop-insurance and subsidy applications
PMFBY (crop insurance) and KCC (Kisan Credit Card) applications require specific area declarations, crop-plan details, and expected-yield estimates. Land Measurement Converter standardises the area to hectares (PMFBY requirement); Crop Yield Calculator provides the expected-yield figure that backs the sum insured.
Post-harvest profit-loss assessment
After harvest, enter actual yield and actual input costs into Farm Profit Calculator for the post-mortem — did the crop meet projected margin, and what variance was from input side vs output side. Useful for next season's planning (input efficiency) and for negotiating with lenders (cash-flow evidence).
How to Choose the Right Tool
For pre-season input planning — Seed Rate Calculator for seed; Fertilizer Calculator for NPK; Irrigation Calculator for water. For land-area work — Land Measurement Converter for any regional-unit-to-acre-or-hectare conversion (registration, insurance, sub-division). For output and profit — Crop Yield Calculator for expected yield estimation; Farm Profit Calculator for the full P&L. Workflow for a full season: Land Measurement Converter (confirm area) → Seed Rate Calculator → Fertilizer Calculator → Irrigation Calculator → (sow) → (grow) → (harvest) → Crop Yield Calculator (enter actual) → Farm Profit Calculator (post-mortem). None of these tools replace an agronomist for soil-test-based prescription or a crop-specialist extension officer for variety selection — they are for quick field-level calculations using ICAR defaults, and the farmer's local Krishi Vigyan Kendra (KVK) is the right source for locality-specific variety and input guidance. For very high-value crops (horticulture, spices, plantation), the recommendation margins are tighter and professional agronomist consultation is worth the ₹1,500-₹3,000 fee.
Agriculture Built for India
Indian agriculture operates on regional and crop-specific conventions that global farming tools get wrong. Land area in rural records uses regional units — bigha, guntha, kanal, cent, marla — that vary not just by state but sometimes by district within state. Our Land Measurement Converter has the state-and-sometimes-district-specific variants. Seed rates and fertilizer dosages are published by the Indian Council of Agricultural Research (ICAR) and state agricultural universities (PAU Ludhiana, GBPUAT Pantnagar, IARI New Delhi, TNAU Coimbatore, PJTSAU Hyderabad); we use the generally-applicable recommendations and flag when your state has a specific override. Irrigation practices are dominated by flood irrigation (especially paddy in Punjab and Haryana) but shifting toward drip (cotton in Maharashtra, horticulture in Karnataka) — our Irrigation Calculator handles all three methods (flood, sprinkler, drip) and quantifies the 40-60% water savings of drip that matter critically for groundwater-stressed regions. Farm profit math must account for MSP vs mandi-rate realities — for crops covered by MSP (paddy, wheat, pulses, oilseeds), the MSP sets a floor; for others (vegetables, fruits), mandi rates can swing 30-50% seasonally. Our Farm Profit Calculator handles both and flags the unhedged price risk on non-MSP crops.
