With this information, Korea Watanabe can provide a system recommendation identifying which machines to purchase first, the applicable subsidy, the expected first-year revenue improvement, and the seasonal calendar for the specific altitude and county.

The full system can be built at the pace that the cleared-field revenue supports.<\/p>\n<\/details>\n<details style=\"border-bottom: 1px solid #e5e5e5; padding: 16px 0;\">\n<summary style=\"font-weight: bold; color: #1a1a1a; cursor: pointer; line-height: 1.5;\">What is the realistic Korean highland potato income per hectare after stone clearing?<\/summary>\n<p style=\"margin: 12px 0 0 0; color: #555; line-height: 1.8;\">The honest answer ranges from 19,000,000 KRW\/ha (gross, cooperative channel, un-cleared baseline) to 54,000,000 KRW\/ha (gross, direct market with cold storage, Year 4+ Dubaek). A realistic Year 2 target for a cleared field with GAP certification and cooperative-to-direct market transition is approximately 28,000,000\u201334,000,000 KRW\/ha gross. After input costs (seed, fertiliser, pesticides, irrigation: 4,000,000\u20137,000,000 KRW\/ha) and machinery operating cost (approximately 3,000,000\u20135,000,000 KRW\/ha), net income per hectare typically reaches 18,000,000\u201322,000,000 KRW\/ha by Year 2\u20133 on a well-managed 10 ha Korean highland potato system with full clearing and GAP certification established. These figures are illustrative \u2014 Korea Watanabe provides farm-specific projections using your actual land area, tractor inventory, and target variety at the consultation stage.<\/p>\n<\/details>\n<details style=\"border-bottom: 1px solid #eee; padding: 16px 0;\">\n<summary style=\"font-weight: bold; color: #1a1a1a; cursor: pointer; line-height: 1.5;\">Is Gangwon-do potato farming viable for farms below 5 ha?<\/summary>\n<p style=\"margin: 12px 0 0 0; color: #555; line-height: 1.8;\">Yes, though the economics of the full machinery system are tighter at smaller scale. For farms below 5 ha, the recommended approach is: (1) hire a THOR 2.4 contractor for primary clearing (eliminating the machine capital cost while achieving the clearing outcome); (2) purchase the EP-EW-4000 rock rake for annual maintenance (appropriate for a 75\u2013100 HP tractor at much lower cost than the THOR 2.4); and (3) contract potato planting and harvest until the farm&#8217;s revenue supports the full machinery investment. At 3\u20135 ha scale with this hybrid contractor-and-own-machine approach, the quality improvement from stone clearing is fully achievable, and the net income per hectare trajectory is similar to a larger farm \u2014 the difference is that the scaling-up path takes longer because the per-hectare revenue base is smaller.<\/p>\n<\/details>\n<details style=\"border-bottom: 1px solid #eee; padding: 16px 0;\">\n<summary style=\"font-weight: bold; color: #1a1a1a; cursor: pointer; line-height: 1.5;\">Which potato variety should a beginner Korean highland farmer start with?<\/summary>\n<p style=\"margin: 12px 0 0 0; color: #555; line-height: 1.8;\">Sumi is Korea Watanabe&#8217;s consistent recommendation for first-year Korean highland potato farmers. Sumi has the widest market channel access (cooperative to direct market), the most forgiving management requirements of the four main highland varieties (Sumi, Daejima, Dubaek, Atlantic), and the broadest altitude tolerance (500\u2013800 m). It produces reliable Grade 1 results on well-cleared highland fields and is the variety most likely to be accepted by all market channels including the cooperative bulk market as the fallback. In Year 2 or 3, once clearing is established and market relationships are developing, diversification into Dubaek (for cold storage premium) or Daejima (for large-tuber premium) can be introduced on specific field blocks without disrupting the Sumi base. Starting with multiple varieties simultaneously increases management complexity and market channel requirements before the foundation systems are stable.<\/p>\n<\/details>\n<details style=\"padding: 16px 0;\">\n<summary style=\"font-weight: bold; color: #1a1a1a; cursor: pointer; line-height: 1.5;\">How long does the Korean highland potato farming system take to become fully self-funding?<\/summary>\n<p style=\"margin: 12px 0 0 0; color: #555; line-height: 1.8;\">The Stage 1 machine investment (THOR 2.4 + CT-2100 after 40% subsidy) is recovered within the first cleared-field growing season for most 10 ha Korean highland potato operations. Stage 2 (PSW-3200 + EP-EW-4000) is funded from Year 1&#8217;s additional revenue and applied in January of Year 2 \u2014 the machinery costs are effectively pre-funded before the January application. Stage 3 (full <a style=\"color: #f07c00; text-decoration: none; font-weight: bold;\" href=\"https:\/\/rock-crusher-tractor.com\/ko\/product-category\/potato-machinery\/\">\uac10\uc790 \uae30\uacc4<\/a>) is funded from Year 2&#8217;s higher direct-channel revenue and applied in January of Year 3. By Year 3, the complete system is in place with all investments funded from cleared-field revenue, not from external borrowing. From Year 3 onward, the annual machinery operating cost (fuel, wear parts, maintenance) of approximately 12,000,000\u201318,000,000 KRW per year is a small fraction of the annual revenue \u2014 the system becomes a stable, self-funding enterprise. The five-year point is where most Korean highland farmers describe the transition as complete: the stone has depleted to maintenance level, the market channels are established, GAP is certified, and the income trajectory is predictable.<\/p>\n<\/details>\n<\/div>\n<p><!-- \u2550\u2550\u2550 CTA \u2550\u2550\u2550 --><\/p>\n<div style=\"background: linear-gradient(135deg,#1a1a1a 0%,#2d2d2d 100%); color: #fff; padding: 44px 5%; border-radius: 8px; margin-top: 60px; text-align: center; box-sizing: border-box;\">\n<p style=\"font-size: clamp(18px,2.4vw+9px,26px); font-weight: bold; margin: 0 0 12px 0; color: #f07c00;\">Start Your Korean Highland Potato System \u2014 Free Consultation<\/p>\n<p style=\"margin: 0 0 12px 0; color: #ccc; font-size: clamp(13px,1.3vw+8px,15px); max-width: 600px; margin-left: auto; margin-right: auto;\">Tell Korea Watanabe your land area, altitude, current tractor, and target crop.
