Sunflower Stalk Bale Supply
Sunflower stalks are the thick, woody stems left in the field after the sunflower harvest. They are usually chopped and worked into the soil, but gathered and baled they become an industrial fuel. Biyolink collects sunflower stalks baled after the harvest, verifies moisture and ash with analysis and delivers them to industrial plants — and buys from farmers with sunflower stalks to sell.

What Are Sunflower Stalks, and When Are They Collected?
The combine takes the sunflower heads and leaves the stalks standing or lying in the field. The stalks are thick, with a hard outer layer and a spongy pith. Once dry in the field they are raked and baled; stalks that are not collected are usually chopped and worked into the soil.
Thrace is Türkiye’s main sunflower region — Tekirdağ, Edirne and Kırklareli — with Konya and Adana also prominent. The harvest is in midsummer in Çukurova and in August–September in Thrace; the stalks are collected once dry, mainly in September–October.
Typical Technical Values
| Property | Typical value |
|---|---|
| Net calorific value | About 2,500–3,300 kcal/kg depending on moisture |
| Moisture | 15–25% (stalks dried in the field) |
| Ash | 7–12% |
| Bale | Round or square; thick stalks resist compression, so bales stay light |
| Form | Bales or chopped stalks; shredded on site before feeding |
These are typical ranges from published sources; actual values vary by lot, source and moisture. We share a laboratory analysis of every lot with our quote.
What Are Sunflower Stalks Used For?
Sunflower stalks are chopped and worked back into the soil and used to a limited extent as livestock bedding; in industry they are a fuel and a raw material for pellets. As a fuel they arrive baled and are shredded at the plant before going into the boiler or kiln. Their ash, potassium and chlorine content is well above wood’s, so boiler design and blend ratio matter to limit slagging and fouling; published studies recommend blending them with woody biomass.
- Alternative fuel in cement kilns
- Biomass boilers and power plants designed for bales
- Blends with wood chips and similar fuels
- Raw material for pellets and briquettes
Transport and Delivery
Bales travel by truck; sunflower stalk bales are light, so vehicles fill by volume before weight and stacking decides the tonnage per run. At the plant they are unloaded by forklift or bale clamp. They should be covered in transit and stored under cover to keep the rain off. Every shipment is recorded with a waybill and a weighbridge ticket.
What Determines the Price of Sunflower Stalk Bales?
The price depends on the harvest season, bale quality and haulage distance. We build our quote around:
- Bale moisture and soil/ash content
- Bale weight and density (tonnage per run)
- Distance from the collection area to the delivery point
- Volume and delivery schedule

Frequently Asked Questions
What is the calorific value of sunflower stalks?
Published sources give sunflower stalks a net calorific value of about 2,500–3,300 kcal/kg depending on moisture. Ash is high at 7–12%; we share an analysis of every lot.
What are sunflower stalks used for?
Chopped and worked into the soil they add organic matter; gathered and baled they become fuel for industrial boilers and cement kilns and a raw material for pellets and briquettes. Biyolink buys baled sunflower stalks as fuel and delivers them to industry.
Can sunflower stalks be baled?
Yes. Once dry in the field, the stalks are raked and pressed into round or square bales. Thick stalks resist compression, so a bale is usually lighter than a straw bale of the same size; tonnage per run and haulage planning matter.
Should I chop sunflower stalks into the soil or sell them?
Both are valid. Chopping them into the soil adds organic matter but takes extra work and fuel; baling and selling them earns an extra income. Ask your agronomist about your soil; if you decide to sell, list them and we will send our price.
