How Organic Fertilizers and Biological Preparations Transform Potato Farming
A silent revolution beneath our feet in the rich soils of Polissya
In the rich, dark soils of Polissya, a quiet agricultural revolution is underway. For decades, conventional farming relied heavily on synthetic fertilizers and chemical interventions to boost crop yields. But as environmental concerns grow and consumers become more health-conscious, farmers and scientists are returning to nature's own solutions: organic fertilizers and biological preparations. This shift isn't merely a nostalgic return to traditional methods—it's a sophisticated integration of ancient wisdom and modern science that could redefine sustainable agriculture.
The humble potato, a global staple crop feeding millions worldwide, stands at the center of this transformation. Recent research conducted in the Polissya region of Ukraine reveals remarkable findings: the strategic combination of organic fertilizers and biological preparations can significantly enhance potato growth, development, and yield while building healthier soil ecosystems 2 .
This approach doesn't just produce potatoes—it cultivates resilience beneath our feet, offering a blueprint for sustainable food production that benefits both people and the planet.
Unlike their synthetic counterparts, organic fertilizers derive from natural sources such as plant matter, animal waste, or minerals. They don't just feed plants—they nourish the entire soil ecosystem.
Biological preparations consist of beneficial microorganisms or plant extracts that enhance soil health and plant resilience.
From 2021 to 2023, researchers at the Institute of Potato Growing of the National Academy of Agrarian Sciences of Ukraine conducted a comprehensive study to quantify the effects of organic fertilizers and biological preparations on potato cultivation in the Polissya region 2 .
The experimental design included:
The study compared various approaches, including the application of biological preparations alone ("Fitodoktor," "MikoHelp," "Bactofit") and in combination with manure at 40 tons per hectare, against control conditions with no interventions 2 .

The correlation analysis revealed a very strong relationship between leaf area and potato yield (r=0.94), as well as a high strength relationship between plant height and yield (r=0.80) 2 . This underscores how these visible growth parameters directly translate to harvestable tubers.
| Research Input | Type | Primary Function |
|---|---|---|
| Animal Manure | Organic Fertilizer | Provides essential NPK nutrients, improves soil structure |
| Bone Meal | Organic Fertilizer | Supplies phosphorus for root and tuber development 1 |
| Fish Emulsion | Organic Fertilizer | Offers quick nutrient release, especially nitrogen 1 |
| "Fitodoktor" | Biological Preparation | Enhances plant growth and disease resistance 2 |
| "MikoHelp" | Biological Preparation | Improves nutrient uptake and plant vitality 2 |
| "Bactofit" | Biological Preparation | Supports plant health and growth parameters 2 |
| "Rice P" | Microbiological Preparation | Enhances nutrient availability, particularly phosphorus |
| Bacillus cereus | Biofertilizer | Solubilizes potassium, making it available to plants 9 |
The remarkable results observed in the Polissya study and similar research stem from several interconnected biological processes.
Organic fertilizers improve soil structure, increasing its ability to retain water and nutrients 1 . This is particularly valuable in the sandy soils common in regions like Polissya, where nutrients typically leach away quickly. Meanwhile, biological preparations introduce beneficial microorganisms that create a thriving ecosystem beneath the surface 1 .
Unlike synthetic fertilizers that release nutrients rapidly—often faster than plants can absorb them—organic fertilizers exhibit slow-release properties 1 . This ensures that nutrients become available throughout the growing season, precisely when potatoes need them most.
The findings from the Polissya experiment contribute to a growing body of evidence supporting sustainable agriculture. Research from Poland confirms that appropriate agronomic practices in organic potato cultivation can "largely eliminate the yielding gap between conventional and organic systems" 7 .

Improved soil water retention and ecosystem health
Some biological preparations can be produced locally at lower cost
Minimizing chemical residues in food
Similar research from Egypt demonstrates that combining organic fertilizers like filter cake with biofertilizers such as Bacillus cereus can increase total tuber weight by over 100% compared to control treatments 9 .

The research from Polissya offers more than just improved potato yields—it provides a blueprint for a more sustainable agricultural future.
By harnessing the power of organic fertilizers and biological preparations, farmers can create resilient, productive farming systems that work in harmony with natural processes rather than against them.
As we face the interconnected challenges of climate change, soil degradation, and food security, these approaches offer hope. They demonstrate that we can nourish growing populations while protecting the planet that sustains us. The green tuber revolution happening in the fields of Polissya may well inspire similar transformations across the globe, one potato at a time.
The next time you enjoy a perfectly roasted potato, consider the invisible world beneath the soil—the beneficial microorganisms, the slowly releasing nutrients, the careful science—that made it possible. Our food choices support agricultural systems, and by choosing sustainably grown potatoes, we each become part of this quiet revolution.
