Dept of Environment, Water and Natural Resources - Soil Sodium Toxicity (proportion of land affected)
High natural levels of sodium, that are toxic to some plants, are typically associated with deep subsoil sodicity, high pH, high boron and moderate salinity, and occur mostly in drier parts of the state. Mapping shows the proportion of land with sodium toxicity in the upper 100 cm of soil, while detailed proportion data are supplied for calculating total land areas affected (spatial data statistics).

Dept of Environment, Water and Natural Resources - Soil Sodium Toxicity (depth to toxic layer)
공공데이터포털
High natural levels of sodium, that are toxic to some plants, are typically associated with deep subsoil sodicity, high pH, high boron and moderate salinity, and occur mostly in drier parts of the state. Mapping shows the depth to sodium toxicity of the most severely affected portion of the map unit (provided they occupy at least 30%), while detailed proportion data are supplied for calculating respective areas of each depth to sodium toxicity class (spatial data statistics).
Dept of Environment, Water and Natural Resources - Soil Boron Toxicity (proportion of land affected)
공공데이터포털
Boron is an essential trace element occurring naturally in soil, but is toxic to many agricultural plants at high concentrations. High boron levels are often associated with windblown deposition of marine sediments, lower rainfall areas and impermeable clay layers (due to reduced leaching). Mapping shows the proportion of land with boron toxicity in the upper 100 cm of soil, while detailed proportion data are supplied for calculating respective areas of each boron toxicity class (spatial data statistics).
Dept of Environment, Water and Natural Resources - Soil Aluminium Toxicity
공공데이터포털
Aluminium toxicity in plants can occur even at low concentrations. While present in most soils, the availability of aluminium to plants is highly pH dependent. Mapping shows the proportion of land with aluminium toxicity potential, while detailed proportion data are supplied for calculating respective areas of each aluminium toxicity class (spatial data statistics).
Dept of Environment, Water and Natural Resources - Soil Water Repellence
공공데이터포털
Water repellence, or non-wetting, due to coating of soil particles by waxy materials from the breakdown of plant debris can result in water beading on the surface, uneven wetting and large masses of soil remaining dry. Mapping shows the proportion of land affected and degree of water repellence, while detailed proportion data are supplied for calculating respective areas of each water repellence class (spatial data statistics).
Dept of Environment, Water and Natural Resources - Soil Salinity - Non-watertable
공공데이터포털
Non-watertable salinity (or dry saline land) is where soil contains elevated levels of soluble salts that are not associated with a watertable. Mapping shows the degree of non-watertable salinity, based on the most saline part of the map unit (provided it occupies at least 30%), while detailed proportion data are supplied for calculating respective areas of each non-watertable salinity class (spatial data statistics).
농촌진흥청 국립농업과학원 농경지화학성 통계정보 V2
공공데이터포털
흙토람 농경지 화학성 데이터는 전국 농경지에서 채취한 토양 시료를 분석하여 산도(pH), 유기물 함량, 유효인산, 치환성 양이온(칼륨, 칼슘, 마그네슘), 양이온치환용량(CEC), 염류농도(EC) 등의 주요 화학적 특성을 제공합니다. 이 데이터는 토양의 비옥도와 양분 상태를 과학적으로 진단하고, 작물별 적정 시비처방 및 토양 환경 개선을 위한 기초자료로 활용됩니다. 또한 지속가능한 농업 실현과 더불어, 토양 산성화·염류집적 등 환경 문제에 대한 대응, 농업 정책 수립, 연구 및 교육 자료로도 폭넓게 사용됩니다.
Dept of Environment, Water and Natural Resources - Soil Salinity - Non-watertable (magnesia patches)
공공데이터포털
Non-watertable salinity (or dry saline land) is where soil contains elevated levels of soluble salts that are not associated with a watertable. Magnesia patches occur where high concentrations of this salt extend to the surface and visibly affect plant growth. Mapping shows the proportion of land affected by magnesia patches, while detailed proportion data are supplied for calculating total areas of affected land (spatial data statistics).
