Levels of CO₂ sequestration and atmospheric carbon mineralization in soil based on the application of the natural organic-mineral fertilizer NutriSelect Pure (NSP) plus its carbon footprint and balance.

The natural organic-mineral fertilizer NutriSelect Pure (NSP) utilizes both chemical and biological processes for CO₂ sequestration, which also leads to the conversion of atmospheric carbon into stable forms of mineral carbon that are subsequently deposited in the soil. These processes include mineral carbonation and the activation of soil microorganisms such as Azotobacter (which fix atmospheric nitrogen and convert it into forms available to plants, and also support the carbon mineralization process), as well as the introduction of organic carbon into the soil through fertilization, which over time also undergoes mineralization in the soil.

CO₂ sequestration through the use of NSP

All calculation for a dose of 700 kg of NutriSelect PURE fertilizer per hectare.

1. Sequestration through mineral carbonation.

The main sequestrating minerals in NutriSelect PURE - magnesium /MgO at 7.79% and calcium/CaO at 13.9% of the composition - have the ability to react with CO₂ in the soil through a process known as carbonation. These reactions produce stable carbonates, such as MgCO₃ and CaCo₃, leading to the deposition of carbon in mineral form in the soil.

Mass of MgO in 700kg of NSP: 54.53 kg MgO

Amount of MgO moles: 1,744.1 moles CaO

Amount of CO₂ absorbed by CaO: 76.62kg CO₂

Total CO₂ sequestration involving minerals: 136.18 kg CO₂

Magnesium carbonates (MgCO₃) and calcium carbonates (CaCO₃) are durable compounds that remain in the soil, stabilizing carbon for long periods and limiting its release back into the atmosphere (unless environmental conditions change drastically, which could lead to the degradation of these compounds).

CO₂ sequestration involving organic carbon.

The organic carbon in NSP fertilizer is converted into stable forms of mineral carbon by soil microorganisms.

Mass of organic carbon in 700 kg of NSP: 210 kg of organic carbon

CO₂ sequestration involving organic carbon: 771.7 kg CO₂

Total CO₂ sequestration per hectare: 907.88 kg CO₂

Carbon footprint

NutriSelect PURE fertilizer has a very low carbon footprint, amounting to 32.02 kg CO₂e (emissions) per ton of finished product. In contrast, the average carbon footprint for synthetic NPK fertilizer is estimated at around 9,800 kg CO₂e (emissions) per ton produced. This means that the carbon sequestration potential of NSP in soil clearly exceeds its negative impact on the environment as a source of carbon emissions. It also indicated that the carbon balance resulting from the use of NutriSelect PURE fertilizer is decidedly positive.

NutriSelect PURE fertilizer contributes to CO₂ sequestration, mineralization, and the long-term storage of atmospheric carbon in the soil. As a result, this product has significant potential to support climate goals.

Additionaly, NutriSelect PURE offers a range of benefits, including support for biodiversity, sustainable soil fertility, and positive impacts on human well-being through improved soil quality and agricultural production stability.
