Planting Density & Income Calculator

Turn spacing decisions into numbers: plants per hectare, cuts per year, output in whichever form you actually sell β€” fresh leaf, food-grade powder, feed-grade leaf meal, or dry pods β€” plus revenue, net margin, and the price you need to break even. Below it, the same plan drawn as a harvest calendar against your rainy season, and a separate nursery module for the seedling business. Everything computes live as you type.

The calculator

Sets defaults; customize anything after.
Switches which price drives revenue; pods carry their own density.
Fence rows: set 0 and use length below.
Used only by the fence/boundary preset.
Distance between rows.
Distance between plants in the row.
35–45 intensive Β· 60–75 hedge.
Farmgate price for fresh leaf
Kg fresh per kg dry; default 4.5.
All cash costs; fence = total β‚±/yr.
πŸ”’ Enter your numbers

Fill in area (or fence length) and price to see density, yields, revenue, and margin. A preset loads sensible defaults β€” adjust from there.

Harvest calendar β€” cuts against the rainy season

Timing is where an otherwise sound plan quietly fails: the same block that yields well in a dry month can lose most of its value in a wet one, because leaf that cannot be dried within a day or two discolours and then moulds (see drying and water activity). This calendar draws the plan from the calculator above β€” the same area and cut interval β€” and marks which harvests fall in the months when field drying is unreliable where you are.

Defaults to the month you are reading this in.
Corona climate types, simplified β€” check your own rainfall record.
Fill in the calculator above (area, or fence length) and this calendar draws itself from the same plan.

Nursery economics β€” the seedling enterprise

Selling planting material is the usual first enterprise on a moringa farm: almost no land, cycles in weeks rather than months, cash while your production block matures, and every new grower in the province as a potential customer. The cost and price ranges below come from the nursery section. Note what the margin does when the numbers are unkind β€” a nursery with bought-in media and labour priced at market wage can lose money, which is the point of running the figures before buying bags.

One batch, before losses.
Farmgate range is roughly β‚±10–50 per seedling.
Media, bag, seed or cutting, water and labour per plant.
Non-germinators, culls and hardening-off failures.
🌱 What this module deliberately leaves out

No land or shade-structure cost, no transport to the buyer, and no value on your own labour β€” all three move the margin more than anything you can type here. Losses are applied to the whole batch, so you pay to raise the seedlings you later cull. And bagged seedlings are heavy: if the buyer is an hour away, price the trip before you price the plant. Selling planting material at scale may bring you under Bureau of Plant Industry seed-dealer registration β€” see the nursery section.

How the math works

plants/ha = 10,000 Γ· (row spacing Γ— plant spacing)
total plants = plants/ha Γ— area (or fence length Γ· in-row spacing)
cuts/year = ⌊365 Γ· cut intervalβŒ‹
fresh kg/yr = yield t/ha Γ— 1,000 Γ— area  Β·  adjusted by cut-interval ratio (capped at 1.5Γ—)
dry kg/yr = fresh kg/yr Γ· fresh-to-dry ratio  Β·  leaf meal kg/yr = fresh kg/yr Γ· 4.0
dry pods/yr = 2 t/ha Γ— 1,000 Γ— area (pod orchard only)  Β·  seed = pods Γ— 0.25
revenue = kg of the chosen product Γ— its price  Β·  net = revenue βˆ’ (cost/ha Γ— area)

Worked examples

🌿 1 ha hedge, fresh leaves

1 ha Β· 1Γ—1 m (10,000 plants) Β· 70-day cuts (5/yr) Β· β‚±15/kg farmgate Β· β‚±80,000 costs:

  • Fresh leaf: β‰ˆ 20,000 kg β†’ β‚±300,000 gross
  • Net β‰ˆ β‚±220,000 Β· margin β‰ˆ 73%
  • Break-even β‰ˆ β‚±4/kg fresh

Matches the upper, well-managed end of the economics chapter scenarios.

🚿 1 ha intensive, powder

1 ha Β· 0.45Γ—0.18 m Β· 40-day cuts (9/yr) Β· β‚±450/kg powder Β· 4.5:1 Β· β‚±355,000 costs:

  • Fresh β‰ˆ 45,000 kg β†’ β‰ˆ 10,000 kg powder β†’ β‚±4,500,000
  • Net β‰ˆ β‚±4.1M β€” the optimistic ceiling, achievable only with irrigation, strong fertility, and a committed powder buyer

Run conservative numbers too: halve the yield or price and see how fast the margin compresses.

πŸ«› 1 ha pod orchard, dry pods

1 ha Β· 4Γ—4 m (625 trees) Β· no leaf cuts Β· β‚±30/kg dry pods Β· β‚±35,000 costs:

  • Dry pods: β‰ˆ 2,000 kg β†’ β‚±60,000 gross, plus β‰ˆ 500 kg seed inside them
  • Net β‰ˆ β‚±25,000 Β· margin β‰ˆ 42% Β· break-even β‰ˆ β‚±17.50/kg pods

An orchard is a slower, lower-labour business than a leaf block β€” the pods mature once a year rather than cycling every 60–75 days. Seed is counted but not priced; add it via the oil or planting-seed routes.
