Agricultural lime for farms across the Upper Far North
Agricultural lime is widely used on farms to help reduce soil acidity and create better conditions for pasture growth. Bellingham Quarries produces and supplies agricultural lime locally from three limestone quarries across the Upper Far North.
Limestone aggregate is also available and we can batch an agricultural lime and limestone aggregate 'raceway mix'.
Ag lime is available from:
- Fairburn Limeworks Quarry – Kaitaia
- Paranui Quarry – Taipa
- Otangaroa Quarry – Mangamuka
All three are satellite quarries and are not always staffed, so please contact our main office for more information or to arrange delivery or collection.
Bellingham Quarries are your reliable source for high quality agricultural lime
- Locally produced agricultural lime from three Upper Far North sites
- Consistently finely ground lime verified by regular independent analysis
- Delivery and collection / pick-up options depending on your requirements

Independently analysed agricultural lime
Bellingham Quarries has agricultural lime from all three sites independently analysed, giving current information on its lime equivalent and particle size. The latest analysis, carried out in December 2025, found 98.9–99.4% of the samples passed through a 2mm sieve, while 61.7–66.1% passed through a 0.5mm sieve. Lime Equivalent results ranged from 64.3% to 73.2% CaCO3 across the three samples tested.
These results show that agricultural lime from all three sites is finely ground, with the samples comfortably meeting recognised New Zealand guidelines for agricultural lime particle size. See the results for each quarry - Fairburn Limeworks, Paranui and Otangaroa.
Why agricultural lime matters on Northland farms
Northland soils naturally become more acidic over time, with normal farming practices and nutrient leaching contributing to the process. Agricultural lime helps counter that acidity by raising soil pH and creating better conditions for productive pasture growth.
The benefits go further than simply changing a number on a soil test. Research into the use of lime in Northland has linked liming with improved availability of important plant nutrients, stronger clover growth, greater soil biological activity and improvements in soil structure. The overall aim is healthier, more productive pasture.
How much lime is appropriate depends on the individual farm. Northland trials found that the response varies according to factors including the starting soil pH, soil type, climate and the amount of lime applied, which is why soil testing is an important starting point.
Delivery and collection / pick-up options
You can collect agricultural lime from Fairburn, Paranui or Otangaroa by prior arrangement, or Bellingham Quarries can organise bulk delivery directly to your farm. We have contacts we can put you in touch with who can arrange ag lime spreading.
There is no minimum order quantity – talk to us about what you need.
Independent analysis provides reliable information about the quality of the lime you're buying, including its Lime Equivalent and how finely it has been ground. Bellingham Quarries regularly tests agricultural lime from all three production sites so customers can have confidence in the product being supplied.
Yes. Finer lime has a greater surface area in contact with the soil, which affects how quickly it can dissolve and react. Bellingham Quarries produces consistently finely ground agricultural lime, with recent independent testing showing more than 60% passing through a 0.5mm sieve across all three production sites.
No. Agricultural lime doesn't have to be applied immediately, so it can be delivered and stockpiled (must be kept covered and dry) on-farm until you're ready to spread it.
Agricultural lime from Fairburn, Paranui and Otangaroa quarries is of consistently high quality. The source may depend on practicalities such as your farm location, the quantity required and how the lime will be transported and spread.
