Green Fodder Land Requirement Calculator
Work out how much land you need to grow year-round green fodder for your herd.
Fodder land = annual herd fodder need ÷ fodder crop yield. Year-round green fodder cuts feed cost dramatically. High-yielding multi-cut fodders (hybrid napier ~200–250 t/ha/yr, berseem/maize ~50–100) need less land than the figure shown for low-yield crops.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About Green Fodder Land Requirement Calculator
Green fodder is the cheapest source of nutrients in dairying, so growing enough of it year-round is the foundation of low-cost milk. This tool works out how much land your herd's green-fodder demand requires, given your fodder crop's annual yield. It shows why high-yielding multi-cut fodders like hybrid napier slash the land (and cost) needed compared with low-yield crops — a key planning number when allocating land between fodder and cash crops.

Frequently asked questions
How much land do I need to grow fodder for my cows?+
Multiply animals × daily green fodder × 365 for the annual need, then divide by your fodder crop's yield per hectare. High-yield fodders like hybrid napier (200+ t/ha/yr) need far less land than low-yield crops for the same herd.
How can I grow more fodder on less land?+
Use high-yielding multi-cut perennials (hybrid napier, guinea grass), legume-cereal mixtures (berseem+oats, maize+cowpea), good fertilisation and irrigation, and make surplus into silage so flush-season growth feeds the lean months.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline at the farm and your data never leaves the device.
