Short answer: Dried poultry manure is one of the most useful fertilisers a Ghanaian farm can make from its own birds. Fresh manure is wet, hot and strong enough to burn roots, so dry it or compost it first. Price your bags from the real cost of labour, drying space and bagging, and sell to people who will put it on crops.
Key takeaways
- Fresh manure burns roots, so dry or compost it before any crop sees it.
- Dry it until it crumbles in the hand, not until it looks dry on top.
- Layer manure is richer than cattle dung, so use less per bed and watch the leaves.
- Keep manure from medicated birds away from food crops until your vet clears it.
- Price each bag from the full cost of the batch, not from what the heap looks worth.
Why the heap behind the house is worth more than you think
Fresh manure from a layer or broiler house is one of the richest things a farm produces. Chicken droppings carry nitrogen, phosphorus and potassium, the three nutrients that most Ghanaian soils run short of. Dried layer manure is often quoted at around 2 to 3 percent nitrogen on a dry weight basis, against well under 1 percent for cattle dung. Results vary with the bird's diet and the bedding, so treat those figures as ballpark and send a sample for a lab test if you sell by the bag.
The catch is what comes with that richness. Fresh manure is wet, it gives off ammonia, and it carries salts that dry out and burn young roots. It also carries whatever the birds carry, including bacteria. The value of the manure depends on what you do with it in the first few weeks after it leaves the house.
Many farms treat the heap as a waste problem. It sits at the edge of the yard, the smell drifts over the fence, and the flies arrive in May. Turn the same heap into a dried, bagged, labelled product and it stops being a complaint and starts paying part of the feed bill.
Fresh, dried or composted: which form to use
The table is a decision aid. Pick the form that suits the crop, the time you have and the buyer you are selling to.
| Form | Moisture and smell | Risk to crops | Best use |
|---|---|---|---|
| Fresh from the house | Wet, strong ammonia smell | Burns roots and seedlings, can spread pathogens | Bare ground well before planting, never on food eaten raw |
| Dried and crumbly | Dry, faint smell, breaks apart in the hand | Low, if kept dry and used in measured amounts | Top dressing for maize, vegetables and nursery beds |
| Composted | Dark, earthy, no ammonia | Lowest, once the heat phase is finished | Potting mixes, orchards and vegetable beds |
Most farms with a few hundred birds do best with dried manure for field crops and composted manure for vegetables and nursery beds. Fresh manure only makes sense when you can leave it on bare ground for weeks before planting, and even then it is a rough way to feed soil. If you want the composted form, our guide to composting litter safely takes you through the heap from start to finish.
Drying manure on a Ghanaian farm
Drying is the step that makes manure sellable. The aim is to bring the moisture down from the three-quarters you start with to something a hand can crumble. Spread the manure thinly on a clean concrete floor or a tarpaulin under cover, and turn it every day or two. Thin layers dry. Deep heaps just sour.
The harmattan does much of the work. Dry, dusty air pulls moisture out fast, so you may have a usable product within a week in January. The rainy season runs the other way. Put a roof over the drying area, or plan to dry in the dry spells and keep the rest under cover. Wet manure in a bag heats, goes mouldy and smells, and a buyer will notice within a day.
Test the stage with your hand. Squeeze a fistful. If it sticks in a wet clump that leaves water on your palm, it needs more time. If it breaks into loose crumbs that feel dry, it is ready to bag. Bag only in dry conditions, keep the bags off the ground and out of the rain, and keep them away from the birds, who will open a bag if they can reach it.
Keep manure from birds that are still inside a medicine withdrawal period separate from the rest. The house routine that produces this manure is in our broiler litter management guide, and it shapes how dry the litter arrives at the heap. Label that heap, and ask your vet when it can join the general product.
Which crops take it well, and how much to use
Maize, okra, tomatoes, pepper and leafy vegetables are the crops farmers most often use poultry manure on. They respond fast to nitrogen, so the leaves go dark green within a few weeks. That same speed is why the amount matters. Too much gives lush leaves and weak fruit, and too much salt scorches the roots.
A starting point for a small vegetable bed is about one wheelbarrow of dried manure for every two square metres, worked into the top 10 to 15 centimetres of soil before planting. Water it in, then watch the plants. A pale leaf means the crop wants more. Scorched leaf edges, or a lot of leaf with no fruit, mean you overdid it. Adjust the next season by what you saw, and keep a note of the bed and the rate.
For maize on a field, the arithmetic changes with the soil and the crop, and the extension officer at your district office is the right person to ask before you spread a large quantity. Mix the manure in rather than leaving it on the surface. That keeps the smell down and puts the nutrients where the roots can reach them.
Keep fresh or freshly dried manure away from leafy greens you will eat raw. Use the composted product there, and leave as long a gap between application and harvest as your extension service advises.
Who buys it, and how to find them
Your first buyers are usually a short drive away. Vegetable growers on the edge of towns, maize farmers who want a cheaper top dressing, nursery owners who sell seedlings and home gardeners in the city all need it. Some fish pond operators use manure to grow the plankton their fish feed on. That is a different use with its own rules, so ask them how they do it before you agree a price.
Sell by the bag, and say what is inside. A buyer who can see that the bag is dry, labelled with the date and the form, trusts the product. A sack with a split end and no label sells only to the buyer who has no choice. Offer a sample. If a buyer comes back for a second bag, you have a customer. If not, the product or the price needs another look.
Local farmer WhatsApp groups, the agro-input shops in the district and the market stalls that sell seed are good places to put up a notice. Do not promise crop results you have not tested yourself. Let the buyer try a bed first, and let the bed do the talking.
Pricing a bag from the real cost
The commonest mistake is to price a bag from what it looks worth rather than what it cost to make. Add up the costs for one batch: the labour to clear the litter and turn the manure, the drying space (the share of your floor the batch takes up), the bags, the twine, the transport, and the loss from bags that got wet or spoiled. Divide by the bags you actually sell, not the number you hoped to fill. If you are working out what the whole farm earns, our piece on whether egg farming pays and our general profitability guide put manure income in its place next to the birds.
Here is a worked example with made-up figures, so you can follow the method. Say one batch costs GH₵400 in labour and bags, and you lose 5 bags to rain. You sell 35 bags, so the cost is about GH₵11.40 a bag before transport. Add the margin you need to keep going, and you have a price. Use your own figures, and check the result against what the local shops charge for other fertilisers before you put a price on the board.
Keep the pricing simple. Two fixed prices, one for buyers who collect and one for buyers who need delivery, are easier to run than haggling at the gate every week.

The risks people skip over
- Ammonia and smell. A heap left open for weeks becomes a neighbour complaint, and the ammonia it gives off is fertiliser you have paid for and lost.
- Flies and rats. Wet manure draws flies and rodents, and both carry disease back to the flock.
- Pathogens. Fresh manure can carry bacteria that survive in soil for a while. Heat and time reduce them, and drying helps too.
- Medicines. Manure from birds on medicated feed, or inside a withdrawal period, stays out of food crops until your vet says it is clear.
- Salt and overuse. Heavy, repeated use builds salt in the soil. Test the soil every few seasons and cut the rate if the salt climbs.
None of these is a reason to avoid manure. They are reasons to handle it on purpose. A farm that dries, bags and labels its product has dealt with most of them for little extra effort. Hens nearing the end of lay add a different load to the heap, and our guide to spent layers and what to do with old hens covers the timing.
A checklist before you sell your first bag
- Dry the batch until it crumbles in the hand, not before.
- Bag it dry, and label each bag with the form and the date.
- Keep manure from birds on medicine out of the batch until the vet clears it.
- Write down the full cost of the batch, including labour and bags.
- Test a sample on a bed of your own before you advertise it.
- Store bags off the floor, under cover and away from the birds.
- Keep a record of who bought what, so you know whom to call back.
Planning for manure on a farm that buys chicks
If you buy chicks from us, the manure question starts before the first bird arrives. Plan the drying area and the store when you plan the house, not after the first full litter. The site choice decides how far the heap sits from the houses, and our site selection guide covers that before you dig a single post. A big layer flock also makes a bigger drying job, because layer manure is the richest of the lot. Work the manure plan into the batch size you choose.
For the birds, WhatsApp +233 24 915 1503 with the batch size and breed, and we will reply with a price you can check. The broiler chicks page and the layer chicks page set out what each bird needs, and the order form is there once you have decided.
Before the manure can earn you anything, the flock has to be well managed. The health of the birds shows up in the litter, and our notes on biosecurity on a poultry farm cover the routine that keeps the heap clean. Our deep litter guide explains the bedding side, which is where most of the manure starts.
Questions farmers ask
Is poultry manure better than cattle manure for crops?
Usually, weight for weight, yes. Dried layer manure carries considerably more nitrogen than cattle dung, so a smaller amount does the job. That richness is also why it burns plants when you use too much or use it fresh. If you sell by the bag, send a sample for a lab test so your nutrient claims are real.
Can I put fresh chicken manure straight on my vegetables?
No. Fresh manure is wet, gives off ammonia and carries salts that can burn young roots. Dry it or compost it first, and apply it to the bed before planting, with time to settle. Never use fresh manure on leafy greens you will eat raw.
How long does it take to dry poultry manure in Ghana?
In the harmattan, a thin layer on a dry concrete floor can be usable within about a week, turned daily. In the rainy season it takes longer, and you need a roof. Test it by squeezing a handful. It should crumble rather than clump and leave water on your palm.
How much manure per square metre should I use?
A starting point for a vegetable bed is about one wheelbarrow of dried manure per two square metres, worked into the top 10 to 15 centimetres. Watch the leaves. Pale plants need more, and scorched edges or lush leaves with no fruit mean you have used too much.
Do I need a licence to sell poultry manure in Ghana?
Ask your district agriculture office what applies before you sell in volume, and keep your labels honest and dated. Small local sales are simpler than a branded product line, but honest labelling matters from the first bag. Get the current position in writing rather than relying on hearsay from other sellers.
Is manure from birds on medicine safe to use?
Keep it away from food crops until your vet confirms the withdrawal period has passed. Medicines can remain in droppings, so the safe default is to hold that batch back, label it, and use it only on crops that are not eaten.
How should I store bagged manure?
Off the floor, under a roof, away from rain and birds, and apart from the feed store. Keep the bags dry, because wet bags heat, mould and lose nutrients. Check them after the first heavy rain of the season, even if they are stored under cover.
