Soil Types - TSV
Soil types are primarily classified by particle size and composition. Sandy soil has excellent drainage and aeration but low water and nutrient retention. Clay soil has excellent water and nutrient retention but poor drainage and aeration. Humus soil is rich in organic matter and fertile but has low strength and high compressibility. Understanding these soil characteristics and implementing appropriate soil improvement can create an environment suitable for crop growth.

01 sandy-soil Sandy Soil Soil dominated by sand particles with excellent drainage and aeration. Good Good (well-drained) Poor (nutrients leach easily) ["Adding organic matter (compost, leaf mold)","Mulching for water retention","Frequent fertilization"] Mainly sand particles of 2-0.02mm ["Root vegetables (carrots, daikon)","Sweet potatoes","Peanuts"] Poor (low water retention) Light and easy to work
02 clay-soil Clay Soil Soil dominated by clay particles with excellent water and nutrient retention. Poor Poor (tends to be wet) Good (retains nutrients well) ["Drainage improvement","Aggregation through organic matter addition","pH adjustment with lime application"] Clay particles of 0.002mm or less, 25% or more ["Rice (paddy)","Wheat","Soybeans"] Good (retains moisture well) Heavy and becomes hard when dry
03 humus-soil Humus Soil Soil rich in organic matter and fertility. Varies with organic matter decomposition Requires drainage management Extremely good ["Proper drainage management","Mixing with other soils","Ground improvement (for developed land)"] Humus content 20% or more ["Leafy vegetables","Flowers","Seedling cultivation"] Extremely good Light but highly compressible
04 loamy-soil Loamy Soil (Ideal Soil) Ideal soil where clay and sand are mixed and bound by humus. Good Good Good ["Continuous addition of organic matter","Proper tillage management","Use of green manure"] Moderate mixture of clay, silt, and sand ["Almost all crops"] Good Moderately light and easy to work
