Boost the impact of your fertiliser, unlock nutrients from your soil and enhance the growth of your crops by working with us to durably remove carbon from the atmosphere

Growing profits, sustainably

Pressure to farm more sustainably is coming from all sides. A key way to improve the efficiency of farms is by achieving optimum soil pH. Our material works just like ground limestone to amend pH, but has the added benefit of durably removing carbon dioxide from the atmosphere. Applying the material as a liming agent can also help to unlock nitrogen and phosphorus from your soil, while helping to extract greater efficiencies from the fertilisers applied to fields. All positively impacting your bottom line, while helping to reduce the environmental impact of your farm.


Boost fertiliser impact

Enhance nitrogen use efficiency with our material. Correcting soil pH can result in an improvement in NUE where soil P and K is sub-optimal. By optimising soil pH, up to 80kg more N/ha/year can be made available to plants, unlocking soil P and K and increasing the response to freshly applied N, P and K. Our material also releases bioavailable silica, which should strengthen crop stems and lessen the impact pests can have on crop health, potentially decreasing the need to apply pesticides.


Lower emissions

The EPA estimates that the application of agricultural lime in Ireland in 2020 led to 399,480 tCOe being emitted. Our material could potentially eliminate these emissions, as unlike ground limestone (CaCO ), our material does not release CO as it reacts with the acids in agricultural soils. At the same time, increasing soil pH can lead to a decrease in NO emissions, with Teagasc research indicating a 39% reduction in NO emissions can be achieved through soil pH amendment.


Grow farm revenue

There is a lot of interest in soil organic carbon, which can be increased through planting cover crops and adopting a min-till system – working with Silicate in no way impacts your ability to earn additional revenue from adopting these practices. Our material uses soil as a medium, but the carbon, which is inorganic, is actually stored in groundwater and ultimately in the ocean. Meaning that you can still create carbon credits from your soil while partnering with Silicate.

Frequently asked questions

Does Silicate’s material amend pH to the same degree as ground limestone?

Our material changes soil pH at the same rate, or better, as ground limestone. Processed returned concrete achieves the same or better pH shift compared to ground limestone on both arable and grassland fields, as evidenced from our trials.

What is in Silicate’s material?

Our material is processed returned concrete, meaning that it is virgin concrete that was returned to the concrete producer as it was surplus to requirements. Our material satisfies all of the European trace element limits for liming materials, just like ground limestone.

How does the process work, what do I have to pay for?

We partner with farmers to help them farm more sustainably. We cover the cost of the material, and work with you to spread it. We will then monitor the fields for about one year. If you would like to learn more, and be part of the next frontier in agriculture then we would love to hear from you.

I am a landowner, and I want to increase my soil carbon to create my own carbon credits. Is there a clash?

Our material uses soil as a medium, but the carbon is actually stored in groundwater and ultimately in the ocean. Meaning that you can still create carbon credits from your soil while partnering with Silicate. The carbon we remove with our material is inorganic, and so it does not interfere or have an impact on the organic carbon that can be sequestered by planting cover crops and adopting min-till practices, for example.
