Growing Smarter Under Cover: Chamoe Success in South Korea

How one Korean grower uses real-time soil data to improve melon quality and reduce crop loss

Under protected cover in Chilgok County, North Gyeongsang Province, South Korea, Mr. Moon is growing Korean melons (참외, chamoe) with precision and care, powered by real-time data from the Bluelab Pulse Meter.

Chamoe cultivation is deeply rooted in Korean agricultural heritage, but maintaining quality and yield under changing conditions calls for a modern approach. Inconsistent monitoring can lead to over-fertilization, nutrient imbalances, and poor plant health. For Mr. Moon, these were challenges in the past. Now, with the help of the Bluelab Pulse Meter, he can check soil conditions regularly and make informed decisions before problems arise. What was once reactive is now proactive, helping him grow stronger crops with fewer inputs.

Mr. Moon shared how the Bluelab Pulse Meter supports three key areas of his covered cropping system.

Soil Moisture

Overwatering is a major risk in melon cultivation, often causing fruit splitting. Mr. Moon relies on the Pulse Meter to monitor moisture levels closely. He can fine-tune irrigation and maintain the right soil conditions throughout the growing cycle by responding to even small changes.

This helps him avoid water stress, reduce the risk of fruit damage, and ensure consistent crop quality.

Soil Conductivity (EC)

Over-fertilization can lead to nutrient imbalances, salt buildup, and reduced fruit quality. Mr. Moon uses the Pulse Meter to routinely measure pore EC, giving him the information needed to decide whether additional fertilizer is required or if nutrient levels are already optimal.

In one reading, the Pulse Meter recorded a pore EC of 2.6 dS/m. When converted to the saturated paste extract method, this measured approximately 2.0 dS/m, which is within the ideal range for melon cultivation. This confirmed that the soil nutrient levels were sound, even though some yellowing leaves (caused by plant age pictured) might have suggested otherwise.

Soil Temperature

Chamoe seedlings are typically transplanted in winter, between November and December. At this stage, soil temperature is critical for root development and early plant growth.

Mr. Moon uses the Pulse Meter to check the soil is warm enough before transplanting. This helps improve seedling survival and promotes strong early establishment, giving his plants a healthy start to the season.

Where modern tools and traditional melon farming come together

By consistently measuring EC, moisture, and temperature, Mr. Moon is growing smarter under cover and showing how modern tools can support traditional practices. Access to real-time data helps him make better decisions, reduce waste, and increase crop performance.

At Bluelab, we are proud to support growers like Mr. Moon,  who advance precision horticulture while remaining rooted in experience and care.
