2017–2025
During the period 2017–2025, Hasta Eco has transitioned to a regenerative, organic farming system based on intercropping, biological activity, and minimal external inputs. Soil analysis data shows clear and consistent improvements in pH, as well as increased levels of phosphorus (P), potassium (K), and calcium (Ca).
Summary of observed changes
• Clear increase in pH from levels around 5.7–6.2 to stable levels around 6.5–7.0
• Increased levels of phosphorus, potassium, and calcium across large parts of the fields
• Increased humus content and improved soil structure
• Stable production despite reduced or no traditional fertilization
Interpretation of pH development
The observed increase in pH occurred without the addition of lime or other direct pH-increasing inputs. This indicates that the change is primarily biologically driven. Soil pH is a result of the interaction between chemical and biological processes, where microbial activity and ion balance play a crucial role.
By reducing the use of synthetic inputs while increasing biological activity, the system has shifted from a chemically controlled to a biologically balanced state.
Connection to nutrient development (P, K, Ca)
Previous analysis showed that levels of phosphorus, potassium, and calcium have increased during the same period. This cannot be explained by the addition of mineral fertilizers, but instead points to increased availability of existing resources in the soil.
The most likely explanation is that the biological system has released nutrients that were previously chemically bound or sparingly soluble. Through microbial activity, root exudates, and improved soil structure, these nutrients have become plant-available and thus measurable in soil analysis.
Driving processes behind the development
• Microbial mobilization: Microorganisms dissolve mineral-bound nutrients and release phosphorus and potassium
• Root activity: Deeper and more active root systems transport nutrients from deeper soil layers
• Calcium dynamics: Increased calcium availability stabilizes pH and improves soil structure
• Increased humus content: Higher organic matter provides better buffering capacity and increased cation exchange capacity (CEC)
• Intercropping: Diversified plant systems create a more stable and functional microbial network
System change – from input to function
The results show that it is not just about adding nutrients, but about activating the soil's own processes. The Hasta Eco system is based on releasing and circulating the resources already present in the soil, rather than continuously adding external inputs.
This means that the soil's inherent fertility is reactivated, leading to more stable and long-term sustainable production.
Conclusion
The observed pH increase combined with increased levels of phosphorus, potassium, and calcium provides strong evidence that the biological system is functioning. By building up microbial activity, increasing humus content, and creating a diversified cultivation system, the soil's function has significantly improved.
In summary, the results show that a regenerative agricultural system can restore the soil's natural balance, improve nutrient availability, and reduce the need for external inputs – while maintaining production levels.
