Fertiliser charts are written in kg per 10 ares. Your bed is three
square metres. RowYield does the hundredfold conversion so you don't
have to guess.
MEASURE THE BED
- Enter length and width; the area appears as you type
PICK A CROP
- 21 crops, every figure sourced from published agricultural guidance
- Spacing fills in automatically and the plant count appears at once
GET THE GRAMS
- Official rates come in kg/10a. Your bed is a few square metres.
RowYield converts, and shows the working
- Enter what's in your shed — 8-8-8, 14-14-14, or your own blend
- Crop-specific warnings where too much nitrogen does real harm:
sweet potatoes run to vine, broccoli goes hollow-stemmed
KNOW WHEN, AND ROUGHLY HOW MUCH
- Harvest dates from published days-to-maturity figures
- For cabbages and radishes, a weight range. For tomatoes and
cucumbers, only the window and the weekly pace — a season's total
swings too much with pruning and watering to state as a number
- Where no yield figure exists in the literature, the app says so
YEAR-ROUND CALENDAR
- Planting dates, side-dressing timing, and harvest windows line up
on a single timeline
- See what to do and when, across all your beds at once
GET A SHOPPING LIST PER BED
- Shows the seedlings or seed count, base fertilizer, and
side-dressing needed for one bed
- Share it as plain text — a shopping list you can take with you
Record what you actually harvest and, after two seasons, your own
numbers take over — with the published figures kept alongside.
Figures come from Japanese prefectural and national agricultural
guidance. Check your local recommendations before applying.
