Our Brewery for Plant Health

There is a common myth that imbalances in insect populations will disappear if agricultural systems are brought “back into balance.” This assumption rests on the idea that agriculture itself is a balanced ecosystem, which is fundamentally incorrect. Agricultural systems—even in their most natural forms—are human-designed systems, shaped by human needs, diets, and production goals.

Agricultural systems—even in their most natural forms—are human-designed systems, shaped by human needs, diets, and production goals. While diversification and ecological practices can reduce the severity of pest outbreaks, they cannot eliminate them. Modern agriculture, which serves diets limited to a relatively small range of vegetables and fruits, necessarily restricts the diversity that can be accommodated on the farm. In this sense, persistent insect pressure is an inherent feature of agriculture. It cannot be completely resolved, only moderated through careful and continuous management (Oerke, 2005). Moreover, pest pressure today is shaped not only by on-farm diversity, but by the biology of the larger landscape and by changing climatic conditions. Research in agroecology and landscape ecology helps explain why pest pressure can remain high even in diversified farms. Studies show that while ecological practices like crop diversification and habitat enhancement can increase populations of natural enemies, they do not always translate into consistent pest suppression in every field because pest regulation depends strongly on landscape context and habitat structure beyond the farm boundary. For example, natural pest control tends to be stronger in complex, patchy landscapes, with abundant non-crop habitats that support predators and parasitoids, but this effect varies and is not guaranteed (Bianchi et al., 2006; Poveda et al., 2025). Another important limitation of ecological pest regulation lies in the difference between ecological and agricultural time scales. Predator–prey relationships, soil food webs, and habitat-based regulation often require many years to stabilise, whereas farms operate on seasonal cycles that demand immediate outcomes. Farmers must harvest crops within weeks or months, not decades. This temporal mismatch means that even ecologically well-designed farms often need active interventions to bridge the gap between long-term ecological recovery and short-term production needs. In our own production analyses, we found that we lose around 30% of certain crops due to insect damage. These include borers, mealybugs, hoppers, and beetles on brinjal; aphids on long beans; blister beetles on lady fingers and beans; and red gourd beetles on pumpkins, cucumbers, and other gourds—despite years of intercropping, flowering hedges, and multi-layered cropping systems. To prevent severe losses, we have so far relied on neem oil sprays and commercially available biopesticides such as Beauveria bassiana (a fungus) and Bacillus thuringiensis (a bacterium). While effective to a degree, these are purchased inputs. We have therefore been exploring more diverse, farm-made preparations such as Themmor Karaisal, Panchagavya, and fermented leaf extracts using plants like Calotropis, Adhatoda, castor, and moonflower—though not yet with full consistency. Our goal has never been a complete elimination of insects, but the cultivation of systems capable of tolerating a certain level of damage without catastrophic crop loss. So far, we have accepted around 30% as the fair share, our contribution to the ecology, the tax the farmer pays to the land for setting up agriculture. However, given the precarious financial situation on the farm as well as the pressure to deliver more food for the community, we are forced to re-assess if some of these losses can be avoided without damaging the ecosystem. Recently, we met the Aarka team (Elen and Shankar), who have developed formulations aimed at rebuilding functional ecological relationships that were historically embedded in farming systems, though under very different population, climatic, and landscape conditions. Their herbal preparation, Aarka, can be applied in dilution and combined with other ferments—such as oil mixes, fish amino acids, and Themmor Karaisal—for foliar sprays to reduce fungal, bacterial, and insect pressure. These bioferments not only prevent “pests” but also deliver essential herb compounds and micronutrients to the plants, strengthening them and building their own capacity to deal with biological pressures. We organised an afternoon of preparing these different formulations together with our team and developed a plan to use them more consistently, as part of an ongoing effort to reduce crop losses while working within the ecological limits of contemporary agriculture. Our brewery now consists of the following ferments: Aarka solution fermented with sugars and proteins Jeevamrit (fermented mix of cow dung and urine) Panchagavya (fermented mix of the five gifts from the cow–dung, urine, milk, curd, ghee) Themmor Karaisal (fermented mix of curd and coconut milk) Oil concoction (Castor, Mahua, Pongam and Neem oils) Fish amino acids (fish waste fermented with banana) Biopotash solution (ash in rainwater) In the coming days, weeks and months, we aim to consistently inoculate our soil and plant ecology with these ferments and observe the response in terms of plant health and productivity.

Flow of fire and water on the farmㅤㅤ

In the Sāṃkhya school of Indian philosophy, the unfolding of matter from spirit gives rise to the senses and to the five elemental manifestations of the material world. From space, emerges air, the principle of movement, and fire, the principle of transformation. Then comes water, carrying flow, continuity, and the subtle pulsations of energy through matter. From the settling of this movement is born earth, the solid ground where life takes form and rests in its full potential.

From space, emerges air, the principle of movement, and fire, the principle of transformation. Then comes water, carrying flow, continuity, and the subtle pulsations of energy through matter. From the settling of this movement is born earth, the solid ground where life takes form and rests in its full potential. Farming is an interaction of all these elements—an ongoing exchange between soil, water, light, air, and the consciousness of the one who tends them. While the Sun remains the primary fire and source of energy, we now also work with another form of fire: electricity, which powers pumps, motors, vehicles, tools, and the quiet machines woven into daily life on the farm. Similarly, rain brings water in its natural rhythm, but we have also learnt to draw from the rainwater stored underground. The farm has three borewells, each serving a specific area and purpose. In this way, the ancient flows of fire and water manifest today as the flows of electricity and irrigation lines across the land. These flows move together; they remain the source of energy for all work on the farm. Over the last fifty-eight years, these flows have gradually expanded to cover a large part of the farm. But further extension is needed to serve areas still cultivated sub-optimally. One might ask: why expand this infrastructure at all? Shouldn’t some parts remain free of artificial flows? Aren’t the Sun and the rain enough? Isn’t natural vegetation sufficient? These questions are part of an enduring dilemma in human life. Our footprint on the planet is large; the footprint of farming especially so. Agriculture is the world’s largest consumer of water, a driver of deforestation and biodiversity loss, a source of carbon emissions, and—in its industrial form—the cause of immense ecological, animal, and human suffering. In such a scenario, it is natural to think that the solution lies in withdrawal: if only humans stepped back, perhaps the earth would regain its balance. We witnessed glimpses of this during the Covid pandemic, when air grew cleaner and wildlife briefly reclaimed spaces near cities. But this brings us to a deeper question: what then is the role of humanity at all? It cannot be inaction. And as our experience shows, even the smallest human action today has ecological and social consequences. Integral Yoga would tell us that our role is not domination but participation—a conscious collaboration with the creative force of nature for mutual growth and progress. Agriculture is one of the clearest expressions of this human–nature participation. Thus, expanding human activity on the farm can arise from two very different impulses–domination, colonisation, and control, or service to the land and to the community—enhancing the ecosystem, the soil, the earth, and producing food for the people we serve. We strive (with successes and failures) toward the latter. In the coming year, we aim to expand our micro-irrigation network as we establish new orchard blocks and diversify existing fruit areas. This year we have learned how communities of crops support one another and reduce the overall water footprint of the farm—simply because the soil remains densely covered with vegetation: some plants grown as food for the farm, others as food for the soil, insects, bees, and birds. Our primary focus will be the mango and cashew orchards, the oldest sections of the farm, which at present are monocultures. Our experiments with cultivating pineapple, ginger, turmeric, yam, and taro within existing orchards have given remarkable results, and we hope to continue this diversification. And water needs energy to flow. As our irrigation network expands, so does the need for energy—whether through electrical connections, lines, or solar-powered pumps. Meanwhile, some of the existing infrastructure, built over many decades, now needs repair and renewal. These are our goals for the coming year—to tend to the flows of fire and water on the farm, the two essential elements for movement and transformation without which both the earth and human consciousness remain sterile. And given the changes the farm (and Auroville) has witnessed in the last few years,  it is evident that the psyche of the farm too needs a movement and transformation, as it goes through a radical transition socially, politically and economically.

The Unstructured Calling: Finding My Rhythmㅤㅤ

Five months ago, I dedicated myself to a period of deep self-experimentation focused on health. Having spent years consuming raw, plant-based foods, I already understood the immense power of food. Yet, the true revelation, refined after a year spent back in the accelerated pace and sterility of city life following my earlier farm volunteering experiences, was the profound importance of a daily, tangible reconnection with nature, the sun, and, crucially, the soil. That time away crystallized what was missing: the rich, microbial life of a natural farm/forest. Home  »  Blog  »  The Unstructured Calling: Finding My Rhythm and Resilience in AuroOrchard’s Soil The Unstructured Calling: Finding My Rhythm and Resilience in AuroOrchard’s Soil November 2025 · Astha Khandelwal Five months ago, I dedicated myself to a period of deep self-experimentation focused on health. Having spent years consuming raw, plant-based foods, I already understood the immense power of food. Yet, the true revelation, refined after a year spent back in the accelerated pace and sterility of city life following my earlier farm volunteering experiences, was the profound importance of a daily, tangible reconnection with nature, the sun, and, crucially, the soil. That time away crystallized what was missing: the rich, microbial life of a natural farm/forest. I wasn’t just looking for just physical work; my purpose was to reconnect with the land to enhance my personal growth. Having volunteered at farms with rigid schedules before, this time I sought something different: a place that would honor my slow pace and allow me to explore without a structured plan, enabling me to truly understand where I could contribute. That search led me, quite naturally, to AuroOrchard, the source of my weekly basket. When I shared my interests: working with the soil, embracing food, and developing recipes to preserve nutritional integrity. Anshul’s response was one of profound trust: “Just come to the farm and explore for a week. Engage in whatever you feel like.” That openness made me feel I had truly found my place. I began simply by observing the farm’s daily rhythm: the conversations, the mulching, the sowing, the weeding, and the processing. I was just watching, slowing down, capturing little observations, feeling that magnetic pull to return every morning. The Science of Feeling “Called” This daily, effortless call back to the earth aligns beautifully with the science of the Gut-Immune-Brain Axis. The sense of peace and belonging is not abstract; it’s rooted in measurable biological mechanisms. Working near and engaging with the soil exposes us to environmental microorganisms, notably the “feel-good” bacteria Mycobacterium vaccae. This exposure through inhalation of bioaerosols released during farming can stimulate serotonin production in the brain, inducing states of greater happiness and relaxation, and providing a powerful buffer against stress and anxiety. It is, in essence, the body’s co-evolved response to the presence of these “Old Friends” from the natural world, which our immune systems rely on for proper calibration and resilience.  The Grounding Moment and the Salad’s Genesis I’ve spent my initial days just watching… observing the harvesting, mulching, and sowing. (Visit my Instagram profile @dhanyawadearth and check the ‘November Notes’ highlight to see all my observations so far) After a week of gentle observation, my role became concrete. I walked in one morning to find Anshul and Ruben discussing the launch of a new seasonal salad box. “Ruben ask her, she only eats salad” Anshul joked,  Soon, I was tasked with walking the farm with Ruben, harvesting every edible green we could use for a sample salad. As we harvested together, Ruben mentioned, “Astha, thank you. I’ve been so occupied in kitchen experiments that I haven’t visited the farm, the soil in so long. It feels so good to be back.” That spontaneous moment was a powerful demonstration of Earthing or Grounding. The human body is electrically conductive, and direct physical contact with the Earth’s surface, like placing bare hands on the soil, allows it to absorb a continuous supply of free electrons. These electrons function as systemic antioxidants, neutralizing the unstable molecules that drive inflammation. The sense of relief and calm Ruben and I both felt was not just emotional; it was a physical electrical reset, reducing our inflammatory load and enhancing our overall well-being. This biophysical connection is a vital, yet often overlooked, part of preventative health. The Nutritional Mandate: Preserving Life Force The subsequent creation of the Farm Seasonal Salad box, which is now happily finding its way into weekly baskets, was guided by principles that bridge soil health and human physiology: Honoring the Seasonal Offering: We prioritize plants that grow robustly in their home climate. This practice ensures plants produce maximum secondary metabolites, yielding higher polyphenols and, consequently, superior antioxidant potential. This is the critical, indirect link to the human gut microbiome: plants grown in microbially rich soils yield nutrient-dense food which, when consumed, provides the best substrate for a diverse and healthy gut ecosystem. Maximizing Micronutrient Retention: We serve the produce raw because essential compounds like Vitamin C, folate, and many carotenoids are heat-labile. By offering a raw, same-day harvest, we ensure maximum micronutrient retention. Digestive & Antioxidant Support: Raw Papaya contains powerful proteolytic enzymes (papain and chymopapain) that assist protein breakdown and improve gut transit. The Chlorophyll in the greens, molecularly similar to hemoglobin, is studied for its ability to support hemoglobin status and act as an antioxidant defense. The successful launch of the Farm Seasonal Salad box is a true testament to the team’s dedicated work and our collective commitment to nutritional integrity. Since the launch, Janani, Raghu, and Ruben have been actively involved in every meticulous step of production: harvesting, cleaning, sorting, drying, chopping, grating, mixing, and packaging. I am particularly proud of how this initiative operates in a closed-loop system, allowing us to receive immediate feedback from customers and act upon it, be it perfecting a dressing or actively seeking sustainable alternatives to plastic packaging, such as our experiments with banana leaves.
