Food For The Earthworm: Soil Care And Open-Access Agritourism At Gochin Tambun Pomelo Agro Farm
Agritourism is widely promoted across Southeast Asia as a diversification strategy for smallholder agriculture. It provides supplementary income for farmers while connecting urban populations to food production systems. Most businesses control visitor access and charge for entry. Visitor experience is designed as a product distinct from cultivation. Although this approach generates revenue, it can also gradually discourage visitors from returning to the farm.
GoChin Tambun Pomelo Agro Farm is a multi-generational family enterprise on the limestone fringe of Ipoh, Perak. Unlike the typical agritourism farm that collects entrance fees, GoChin developed an alternative approach. Orchard access is free and unrestricted. Cultivation remains the primary activity but visitor engagement operates as an extension of the farm rather than as a separate business line. A visitor survey compiled by the family recorded arrivals from approximately 120 countries. More importantly, the farm has achieved this without paid advertising or any formal marketing campaigns.
Context and Challenges: Fifty Years in the Same Soil
Tambun lies within a limestone valley whose economy depended on tin mining for much of the twentieth century. Commercial cultivation of pomelo dates from the 1940s when tin mining was still dominant. Households combined both activities before moving to full-time fruit production as the mines closed. Labour was typically limited to a married couple in the family working tirelessly without the support of additional staff. Therefore, land size and scale remained small at approximately two to three acres. This limited economies of scale and constrained conventional growth strategies.
The growing conditions in Tambun are hard to find elsewhere. Limestone feeds minerals into the soil, and underground water moves through the valley. The proximity to the hills also produces cool night temperatures. These conditions contribute to the market reputation of Tambun pomelo.
"The pomelo tree majority very old, 50, 60, 70 years old... The soil no change. Still that soil."
While the landscape is ideal, the trees standing on it are old. “The pomelo tree majority very old, 50, 60, 70 years old... The soil no change. Still that soil,” Mr. Tan says. The trees were planted by an earlier generation and the ground beneath them has not been turned over or replanted since. Continuous cultivation over such a long period can progressively deplete the mineral content of the soil. For a business whose assets rest on mature trees, soil conditions are therefore a concern.
Feeding the Soil, Not the Tree
GoChin’s response has been to produce its own fertiliser instead of relying on external inputs (buying conventional fertiliser). The fertiliser is directed at soil biology rather than at the trees. “Actually this fertiliser, it is a food for the earthworm,” the second- generation owner explains. “In our farm, the soil, a lot of earthworm. What we do, we neutralise the soil, so the tree will get strong, get healthy.”
The idea comes from observing forest systems where mature trees persist for decades without external inputs. This method focuses on the conditions that sustain the tree. It does this by balancing the minerals and soil organisms rather than feeding the tree directly. The owner is explicit about the limitations of the approach. The objective is to return the soil to more natural conditions “but not 100%”. This method costs less but takes years. The family will not see returns in a single season. This method also limits rapid scaling. It does, however, suit the asset they are protecting.
Giving the Garden Away
The family also maintains a herb garden containing plants that are traditionally used for skin conditions, liver and lungs complaints, fever, coughs and colds, and diabetes. Some are also taken by people undergoing cancer treatment. These are customary uses and the family makes no therapeutic claims for them.
The garden is not commercialised. Visitors who express interest are shown the beds and given cuttings without charge. Although the herb garden does not add to revenue generation directly, it enhances the visitor experience.
Open-Access Agritourism
The orchard walk is free, self-guided and unrestricted by fixed routes. This model was not planned. It started when coach operators began bringing groups as domestic tourism expanded. Mr. Tan’s family simply accommodated them.
Word of mouth brings in most of the visitors. GoChin’s online presence consists largely of visitor reviews. Repeat visitors return to the farm for the warm hospitality provided by Mr. Tan, his wife and his son. Following the pandemic, visitors began spending longer on site rather than simply purchasing and departing. The family observed this pattern and reconfigured the seating accordingly. Fresh juice and cut fruit from the farm’s own pomelo, guava and starfruit were also offered. Together, these changes built an experiential marketing journey that makes a visit to GoChin distinctive.
Reputation can substitute for marketing expenditure where the underlying experience is consistent.
Lessons and Transferability: What Travels, and What Does Not
The GoChin story shows that a farm does not need built attractions or a ticket gate to be worth visiting. Three of its practices could work elsewhere. First, farming and visits are mutually reinforcing. Because the orchard is still a working farm, what visitors see is the real thing. Second, low-input soil management is well suited to businesses whose productive assets are expected to last for generations.
With the trees expected to stay in the ground for many years more, caring for the soil is the same as maintaining the asset. Third, reputation can substitute for marketing expenditure where the underlying experience is consistent. These practices are replicable. The growing environment that gives the fruit its market position is not. This is why the practices that sustain the farm are worth paying attention to.
