Euiseong-certified garlic commands 8,000\u201320,000 KRW per kilogram at premium markets. A single angular stone at 20 cm depth during bulb development splits that bulb \u2014 and the split bulb grades at 500\u20131,500 KRW per kilogram. The mathematics of Korean garlic farming begins with what is underground.<\/p>\n

Garlic Field Preparation Consultation<\/a><\/p>\n<\/div>\n<\/div>\n

<\/p>\n

Korea produces approximately 270,000\u2013330,000 tonnes of garlic annually \u2014 the third most cultivated vegetable crop after radish and cabbage \u2014 making it one of the most commercially significant highland crops that stone clearing directly affects. Unlike potato, where Grade 1 is defined primarily by tuber size and skin condition, garlic Grade 1 is defined by a single non-negotiable criterion: the bulb must be whole, symmetrical, and undivided at the base. A garlic bulb that has been split \u2014 even partially \u2014 by lateral stone resistance during its underground development is permanently disqualified from the Grade 1 premium market regardless of its size, skin quality, or flavour.<\/p>\n

Korean garlic farming stone clearing<\/strong> is not simply about improving yield. It is about protecting an investment that runs for five to six months in the ground before any result is visible \u2014 and ensuring that the biology of bulb development is allowed to complete correctly. This guide covers the specific stone clearing requirements for Korean highland and lowland garlic production, the biology behind the Grade 1 standard, the Euiseong premium certification system that stone clearing enables, and the complete field preparation protocol from autumn THOR 2.4 pass through to PSW-3200 raised-bed formation.<\/p>\n

<\/p>\n

The Garlic Grade 1 Standard \u2014 Why Stones Create the Damage No Other Factor Does<\/h2>\n

\"THOR<\/p>\n

Korean garlic bulb development occurs underground from March through May on a standard winter garlic production cycle. The bulb initiates at the base of the stem where the clove wrappers form \u2014 at a depth of 8\u201315 cm below the ridge surface. As the bulb expands horizontally from this initiation point, it encounters whatever solid material is in the surrounding soil. The physical mechanism of stone damage in garlic is fundamentally different from the damage mechanism in potato:<\/p>\n

\n
\n

Potato damage mechanism<\/p>\n

A stone redirects the potato’s developing taproot \u2014 the root grows around the stone, producing a forked tuber. The potato continues to grow around the obstruction, producing a misshapen but often full-sized result. Damage is expressed in the elongated or forked tuber shape.<\/p>\n<\/div>\n

\n

Garlic damage mechanism<\/p>\n

A stone applies lateral compressive resistance against the expanding garlic bulb. The bulb’s outer wrapper, expanding outward under its growth pressure, meets the stone and is redirected \u2014 the bulb splits its clove arrangement along one or more cleavage planes, producing a “split” or “double-round” bulb that cannot be sold as Grade 1 whole garlic. Unlike potato, the damage is to the internal architecture \u2014 the bulb can be near full size but completely Grade 2.<\/p>\n<\/div>\n<\/div>\n

The grade shift from 65% Grade 1 (un-cleared) to 91% Grade 1 (stone-cleared) on a Korean garlic farm represents a 40% improvement in the proportion of produce receiving the premium price \u2014 a revenue multiplier that operates on every kilogram produced for as long as the field remains cleared. At Euiseong premium market Grade 1 pricing (8,000\u201320,000 KRW\/Kg for certified whole dried garlic), this grade shift is among the highest-value revenue improvements that stone clearing produces across all Korean highland crops.<\/p>\n

<\/p>\n

The Euiseong Premium \u2014 How Korea’s Most Valuable Garlic Origin Depends on Stone-Free Production<\/h2>\n

Euiseong County (North Gyeongsang Province) is the most recognised garlic origin in Korea \u2014 the registered geographic indication for Euiseong garlic carries a price premium of 2\u20135\u00d7 over equivalent-quality garlic from non-certified origins. Understanding what the Euiseong certification requires \u2014 and how stone clearing interacts with those requirements \u2014 reveals why the clearing investment is a prerequisite for the certification, not an add-on to it.<\/p>\n

\n

Euiseong Garlic Certified Origin \u2014 Key Production Requirements<\/p>\n

\n
Field location requirement:<\/span>
\nRegistered agricultural field within Euiseong County, North Gyeongsang Province. Field must be listed on the county’s certified origin field registry. Stone-cleared fields receive preferential registry listing status \u2014 un-cleared fields with documented production quality below Grade 1 threshold may be de-listed on quality review.<\/div>\n
Grade 1 proportion minimum:<\/span>
\nMinimum 85% Grade 1 whole bulb in any lot submitted for certified origin labelling. This threshold is routinely achieved only on stone-cleared fields \u2014 the 55\u201368% Grade 1 range on un-cleared fields falls below the certification floor, making un-cleared field production structurally ineligible for certified origin status regardless of other factors.<\/div>\n
Variety specification:<\/span>
\nEuiseong certified origin requires production using the registered Euiseong garlic ecotype (smaller clove, more pungent, higher allicin content than standard Korean garlic varieties). The ecotype’s smaller bulb size makes it more vulnerable to stone-related deformation than standard commercial varieties \u2014 stone clearance is even more important for the Euiseong ecotype than for standard Korean garlic.<\/div>\n
Soil pH requirement:<\/span>
\npH 6.0\u20136.5 for the Euiseong ecotype \u2014 tighter than standard Korean garlic’s acceptable range of 5.8\u20137.0. On granite-parent Euiseong soils (naturally pH 4.5\u20135.5), annual lime application through the DCW 2.2 spreader is a certification maintenance requirement, not optional soil improvement.<\/div>\n
GAP certification cross-requirement:<\/span>
\nEuiseong certified origin sales to major Korean retailers (E-Mart, Homeplus, Costco Korea) increasingly require GAP certification alongside the origin certificate. GAP field registration requires the stone-cleared, documented field record that the THOR 2.4 + CT-2100 system’s probe verification procedure produces. The two certifications are operationally linked through the field preparation record.<\/div>\n<\/div>\n<\/div>\n

For Euiseong garlic farmers, the stone clearing investment is not evaluated against a generic Korean highland ROI framework \u2014 it is evaluated against the specific price ceiling of Euiseong certified whole dried garlic at the premium market. The ceiling is substantially higher than for any other Korean highland crop covered in this guide series, which is why the clearing investment’s payback period on Euiseong garlic production is the shortest per-hectare of any Korean highland crop once the certification is established.<\/p>\n

<\/p>\n

Stone Clearing Depth and Timing \u2014 Why Garlic Requires the October Window<\/h2>\n

alt=”CT-2100 rock picker completing stone collection after THOR 2.4 pass \u2014 for Korean garlic production, the CT-2100<\/a> collection must be completed before late October to allow the PSW-3200 raised-bed preparation and November winter garlic planting on schedule”

\nstyle=”width:100%;height:auto;display:block;border-radius:6px;margin:20px 0 28px 0;” \/><\/p>\n

The Korean Garlic Production Cycle \u2014 Understanding the Timing Constraint<\/h3>\n

Korean winter garlic (the dominant production type in Euiseong and Gyeongnam regions) is planted in October\u2013November and harvested in May\u2013June the following year. This planting timing creates a non-negotiable constraint for stone clearing: the THOR 2.4 clearing pass, the CT-2100 collection, and the PSW-3200 raised-bed preparation must all be completed before the November planting window. This gives a maximum of 4\u20136 weeks from the preceding crop’s harvest (typically late September for summer vegetables or early autumn potato) to complete the full stone management and bed preparation sequence.<\/p>\n

<\/p>\n

\n
\n
\n

Option A: October Clearing \u2705<\/p>\n

Recommended for winter garlic<\/p>\n<\/div>\n

\n
\n
\u2713<\/span>THOR 2.4 pass: early\u2013mid October (soil dry, post-harvest)<\/div>\n
\u2713<\/span>CT-2100 collection: immediately after THOR 2.4<\/div>\n
\u2713<\/span>Lime application (DCW 2.2): late October<\/div>\n
\u2713<\/span>PSW-3200 raised bed: early November<\/div>\n
\u2713<\/span>Planting: mid\u2013late November on schedule<\/div>\n<\/div>\n
October soil temperature (8\u201315\u00b0C): optimal for THOR 2.4 granite fragmentation. Dry post-harvest soil reduces CT-2100 collection load. Lime has 2\u20133 weeks to begin neutralising before planting.<\/div>\n<\/div>\n<\/div>\n
\n
\n

Option B: Spring Clearing \u26a0<\/p>\n

Second-best \u2014 only if October missed<\/p>\n<\/div>\n

\n
\n
\u25b3<\/span>Must use spring garlic varieties (different planting window: March\u2013April)<\/div>\n
\u25b3<\/span>THOR 2.4 pass: March (risk of wet soil reducing fragmentation quality)<\/div>\n
\u25b3<\/span>CT-2100 in wet Korean spring soil: bunker fills faster, slower collection<\/div>\n
\u2717<\/span>Cannot use winter garlic ecotype (Euiseong type) \u2014 incompatible with spring planting<\/div>\n
\u2717<\/span>Spring garlic commands 40\u201360% lower price than winter garlic at equivalent Grade 1<\/div>\n<\/div>\n
Use spring clearing only as a fallback when the October window was missed. The price penalty from switching to spring garlic varieties typically exceeds any operational savings from deferred clearing.<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Stone Clearing Depth for Garlic \u2014 25-28cm vs Potato’s 30cm<\/h3>\n

Korean garlic bulbs develop at 8\u201315 cm depth and their root systems extend to 20\u201325 cm. The stone clearing depth requirement for garlic is therefore 25\u201328 cm \u2014 shallower than potato (30 cm) and substantially shallower than ginseng (40 cm). The THOR 2.4 operating at 25\u201328 cm depth on a garlic preparation pass can typically move at a slightly higher forward speed than on a potato or ginseng pass, because the clearing depth is within the machine’s most efficient operating zone for Korean highland granite at the standard stone density.<\/p>\n

One important nuance: garlic’s root zone is shallower than potato’s, but the stones that cause the most damage to garlic bulbs are not primarily the deep-embedded stones at 25\u201330 cm depth \u2014 they are the 10\u201320 cm stones that sit directly at bulb development height. A THOR 2.4 pass that targets 25\u201328 cm depth fragments both the surface stone layer and the 10\u201320 cm zone in a single pass on a previously un-cleared field. On a field that has been cleared in prior years to 30 cm, the garlic annual maintenance pass at 20\u201322 cm is sufficient \u2014 the stones that remained at 20\u201325 cm depth after the initial clearing are smaller and fewer after several frost-heave cycles have progressively moved sub-surface material toward the surface where the CT-2100 can collect it.<\/p>\n

<\/p>\n

PSW-3200 Garlic Raised-Bed Specification \u2014 Different From Potato Ridge Formation<\/h2>\n

\"PSW-3200<\/p>\n

Garlic production in Korea uses raised beds rather than the narrower ridges used for potato. The raised-bed geometry for garlic is specific to its row spacing requirements (Korean garlic is typically planted at 15\u201318 cm between-plant spacing in multiple rows per bed) and its drainage requirement (raised beds ensure that the bulb development zone remains aerated through the spring monsoon period).<\/p>\n

The wider garlic bed allows 4\u20136 rows of planting per bed pass \u2014 covering the same ground area as potato production with fewer PSW-3200 passes because the bed does not require the precise ridge peak geometry that potato planting machines demand.<\/p>\n

<\/p>\n

pH Management for Garlic \u2014 Why the DCW 2.2 Lime Pass Is Non-Negotiable<\/h2>\n

Garlic is one of the most pH-sensitive Korean highland crops. The optimal range of pH 6.0\u20136.5 is narrow \u2014 below pH 5.8, manganese toxicity and calcium deficiency suppress bulb development; above pH 7.0, iron chlorosis appears and allicin synthesis is reduced, lowering the flavour intensity that the Euiseong premium commands. Korean granite parent soils start at pH 4.5\u20135.5 and acidify over time under cropping.<\/p>\n

\n
Application rate:<\/span>
\nKorean garlic fields typically require 2.5\u20133.5 t\/ha of agricultural lime per application cycle (every 1\u20132 years) to maintain pH in the 6.0\u20136.5 range on granite soils under cropping. The DCW 2.2’s 2,140 mm spreading width and adjustable application rate allows precise coverage at these rates on highland terrace dimensions.<\/div>\n
Timing:<\/span>
\nApply lime after CT-2100 stone collection is complete but before the PSW-3200 incorporation pass \u2014 the sequence is THOR 2.4 fragmentation \u2192 CT-2100 collection \u2192 DCW 2.2 lime spread \u2192 PSW-3200 incorporation pass. This sequence ensures the lime is distributed through the full 22\u201325 cm profile in a single PSW-3200 pass, not left on the surface.<\/div>\n
Critical warning:<\/span>
\nDo not apply lime and nitrogen fertiliser simultaneously or within 7 days of each other. Lime raises soil pH immediately around the granule \u2014 if nitrogen (ammonium-based fertiliser) is applied simultaneously, the elevated pH around the lime granule converts ammonium-N to ammonia gas, causing significant nitrogen volatilisation loss. Apply lime at least 1 week before or after any nitrogen fertiliser application.<\/div>\n<\/div>\n

<\/p>\n

5-Year ROI \u2014 Korean Garlic Stone Clearing Investment vs Protected Revenue<\/h2>\n

\"Korean<\/p>\n

Garlic is an annual crop with a 6\u20138 month production cycle \u2014 shorter than ginseng (4\u20136 years) and producing annual revenue rather than the multi-year compounding risk structure of ginseng. However, garlic’s annual revenue per hectare is substantially higher than potato’s, making the 5-year ROI calculation for garlic stone clearing significantly more favourable than for potato at equivalent clearing cost:<\/p>\n

\n

5-Year Garlic Stone Clearing ROI \u2014 1 ha Reference Field (Euiseong type, standard highland rotation)<\/p>\n

\n
Pre-clearing baseline (1 ha):<\/span>

\nTHOR 2.4 + CT-2100 after 40% subsidy: ~24M KRW. Shared with potato and other crops \u2014 garlic’s share of the clearing investment: ~8M\u201312M KRW (proportional to the garlic area’s share of total annual cleared field use).<\/div>\n
Payback period (1 ha garlic):<\/span>
\n~10\u201314 weeks after first Euiseong-certified harvest. The garlic area’s share of the clearing cost is recovered in the first quarter of the first post-clearing production season.<\/span><\/div>\n
5-year cumulative gain (1 ha):<\/span>
\n~39M KRW\/year \u00d7 5 years = ~195M KRW<\/strong> additional revenue from garlic alone, against a garlic-share clearing cost of 8M\u201312M KRW. Return on garlic clearing investment: 16\u201324\u00d7<\/strong> over 5 years.<\/span><\/div>\n<\/div>\n

All figures are representative estimates using conservative pricing. Euiseong premium prices vary with annual supply and market conditions. Certification must be established before the Euiseong price applies \u2014 expect 1 full season at standard non-certified pricing while the certification process completes.<\/p>\n<\/div>\n

\n
\nKorean garlic farming stone clearing guide \u2014 what is the correct THOR 2.4 depth for garlic fields?<\/summary>\n

The recommended THOR 2.4 clearing depth for Korean garlic field preparation is 25\u201328 cm on a first-season clearance of un-cleared ground, and 20\u201322 cm for annual maintenance passes on previously cleared fields. The 25\u201328 cm initial clearing depth targets the 10\u201325 cm stone zone that directly affects garlic bulb development \u2014 stones at this depth are the primary cause of Grade 2 bulb splitting. Stones below 25\u201328 cm are generally below the garlic bulb’s development and root zone and do not need to be targeted in the garlic-specific clearing pass (unlike ginseng, which requires clearing to 40 cm for the taproot development zone). The THOR 2.4 at 25\u201328 cm operating depth on Korean highland granite at garlic-season soil moisture conditions (typically post-October harvest, moderately dry) can operate at 1.5\u20132.0 km\/h forward speed \u2014 slightly faster than the potato or ginseng preparation depth settings.<\/p>\n<\/details>\n

\nWhat is the Euiseong garlic stone-free production standard and can other Korean counties achieve the same price premium?<\/summary>\n

Euiseong garlic’s certified geographic indication (GI) is specific to Euiseong County, North Gyeongsang Province \u2014 it cannot be claimed by garlic from other counties regardless of production method or quality level. However, other Korean garlic production regions have developed their own premium origin identities that command above-standard pricing for Grade 1 whole dried garlic from verified origins: Namhae garlic (South Gyeongsang), Taean garlic (South Chungcheong), and Uiseong garlic all command premiums above the standard cooperative market price for whole Grade 1 garlic from certified origin producers. The stone-free Grade 1 production threshold that enables premium market access applies across all these regional designations \u2014 the exact price premium varies by region and market year but the underlying production requirement (85%+ Grade 1 whole bulb) is consistent. Korea Watanabe provides guidance on the premium destination applicable to the specific garlic production county for any customer consultation.<\/p>\n<\/details>\n

\nCan garlic and potato be grown in rotation on the same stone-cleared field?<\/summary>\n

Yes \u2014 garlic and potato rotation on the same stone-cleared Korean highland field is agronomically compatible and economically advantageous. Both crops benefit from the same stone-clearing standard (though garlic at 25 cm vs potato at 30 cm means the garlic field’s clearing is effectively a subset of the potato field’s clearing requirement). The rotation breaks the monoculture disease build-up that both crops are prone to: potato follows garlic without the solanaceous pathogen accumulation that occurs under continuous potato production, and garlic follows potato with the benefit of the soil structural improvement from the potato’s deeper root system. One important constraint: do not plant garlic in soil where alliums (garlic, onion, leek) have grown within the previous 3 years \u2014 the soil-borne pathogen Fusarium culmorum accumulates under continuous allium cropping and directly attacks garlic roots. A cereal or brassica break crop is recommended between garlic rotations on the same field. Korea Watanabe’s rotation planning consultation covers the optimal crop sequence for the specific cleared field.<\/p>\n<\/details>\n

\nIs there a specific garlic variety that responds better to stone clearing than others in Korean highland conditions?<\/summary>\n

The Euiseong ecotype (small-clove, high-pungency winter variety) responds most dramatically to stone clearing because its smaller bulb diameter makes it more sensitive to lateral stone resistance than large-bulb commercial varieties. Standard Korean commercial winter garlic (Namdo, Daesan types) also benefits significantly from stone clearing but at slightly lower Grade 1 uplift percentage than the Euiseong ecotype. For stone-cleared fields being developed for premium garlic production, Korea Watanabe recommends starting with the Euiseong ecotype if the field is in the Euiseong County zone, or the regionally appropriate ecotype for other certified origin zones. For non-premium market production, commercial winter varieties (Namdo-type) are more tolerant of residual stone populations than the Euiseong ecotype and produce reliable Grade 1 proportions on fields that have received partial rather than complete stone clearing treatment.<\/p>\n<\/details>\n

\nDoes the Korean agricultural machinery subsidy apply to THOR 2.4 purchases for garlic field preparation specifically?<\/summary>\n

Yes \u2014 the Korean agricultural machinery subsidy applies to the THOR 2.4 \u5ca9\u77f3\u7834\u788e\u673a<\/a> regardless of which crop the cleared field will be used for. The subsidy is applied to the machine purchase, not to the crop \u2014 a garlic farmer purchasing a THOR 2.4 for garlic field preparation receives the same 40\u201350% subsidy rate as a potato farmer purchasing for potato field preparation. The subsidy application requires a registered agricultural field and a farm household registration, both of which a garlic farmer in a certified origin zone would typically already hold. Korea Watanabe prepares the subsidy documentation for garlic farmers in the same way as for potato farmers \u2014 the January application window, county quota system, and 5-year compliance period all apply equally. Contact Korea Watanabe in October\u2013November to begin the combined subsidy and field preparation planning process for the following January application window.<\/p>\n<\/details>\n<\/div>\n
