Il-proporzjonijiet relattivi tal-ħamrija varji tifred fil-ħamrija kif deskritt mill-klassijiet ta ' l-istruttura tal-ħamrija muri fil-Fig. 1. L-klassijiet textural jistgħu jiġu modifikati biż-żieda ta ' aġġettivi xierqa meta blat frak huma preżenti fl-ammonti sostanzjali; per eżempju, "" naqal ġeblija loam."" (Għal modifikaturi oħrajn tal ara wkoll biċċiet ta ' blat.) -Loam tar-ramel, loamy ta ' ramel, u bir-ramel huma subdiviżi aktar fuq il-bażi tal-proporzjonijiet tal-varji tar-ramel tifred preżenti. L-limiti tal-klassijiet u s-subklassijiet varji huma kif ġej:

tal-fuħħar - ħamrija ta ' materjal li fih 40% jew aktar tal-fuħħar, < 45% ramel, u < 40% tat-tajn.

tal-fuħħar loam - ħamrija ta ' materjal li fih 27 sa 40% tal-fuħħar u 20 sa 45% tar-ramel.

loam - ħamrija ta ' materjal li fih 7 sa 27% tal-fuħħar, naqal 28 sa 50%, u < 52% ramel.

ir-ramel loamy - ħamrija ta ' materjal li jkun fih bejn 70 u 91% tar-ramel u l-perċentwali ta ' naqal biż- żieda ta ' 1.5 darbiet il-persentaġġ ta ' tafal huwa 15 jew aktar; u l-perċentwali ta ' naqal biż- żieda ta ' darbtejn il-persentaġġ ta ' tafal huwa anqas minn 30.

• loamy coarse sand - Soil material that contains 25% or more very coarse and coarse sand, and <50% any other one grade of sand.
• loamy sand - Soil material that contains 25% or more very coarse, coarse, and medium sand, <25% very coarse and coarse sand, and <50% fine or very fine sand.
• loamy fine sand - Soil material that contains 50% or more fine sand (or) <25% very coarse, coarse, and medium sand and <50% very fine sand.
• loamy very fine sand - Soil material that contains 50% or more very fine sand.

• coarse sand - Soil material that contains 25% or more very coarse and coarse sand, and <50% any other one grade of sand.
• sand - Soil material that contains 25% or more very coarse, coarse, and medium sand, <25% very coarse and coarse sand, and <50% fine or very fine sand.
• fine sand - Soil material that contains 50% or more fine sand (or) <25% very coarse, coarse, and medium sand and <50% very fine sand.
• very fine sand - Soil material that contains 50% or more very fine sand.

bir-ramel tal-fuħħar loam - ħamrija ta ' materjal li jkun fiha 20 sa 35% tal-fuħħar, < naqal 28%, u > ramel 45%.

bir-ramel loam - ħamrija ta ' materjal li fih 7 sa 20% tal-fuħħar, aktar minn 52% tar-ramel, u l-perċentwali ta ' naqal biż- żieda ta ' darbtejn il-persentaġġ ta ' tafal huwa 30 jew aktar; jew anqas minn 7% tal-fuħħar, inqas minn 50% tat-tajn, u aktar minn 43% tar-ramel.

• coarse sandy 1oam - Soil material that contains 25% or more very coarse and coarse sand and <50% any other one grade of sand.
• sandy loam - Soil material that contains 30% or more very coarse, coarse, and medium sand, but <25% very coarse and coarse sand, and <30% very fine or fine sand, or <15% very coarse, coarse, and medium sand and <30% either fine sand or very fine sand and 40% or less fine plus very fine sand.
• fine sandy loam - Soil material that contains 30% or more fine sand and <30% very fine sand (or) between 15 and 30% very coarse, coarse, and medium sand, or >40% fine and very fine sand, at least half of which is fine sand, and <15% very coarse, coarse, and medium sand.
• very fine sandy loam - Soil material that fih 30% jew aktar ħafna ramel fin u < 15% ramel oħxon, oħxon, u ħafna medju (jew) > 40% multa u ħafna multa ramel, aktar minn nofs li huwa ramel irqiq ħafna u < 15% ħafna oħxon, oħxon, u l-medja tar-ramel.

tat-tafal silty - ħamrija ta ' materjal li fih 40% jew aktar tal-fuħħar u 40% jew aktar tat-tajn.

silty tal-fuħħar loam - ħamrija ta ' materjal li fih 27 sa 40% tal-fuħħar u < 20% ramel.

jinżlu loam - ħamrija ta ' materjal li fih 50% jew aktar tat-tajn u 12 sa 27% tal-fuħħar (jew) tat-tajn ta ' 50 sa 80% u < tafal 12%.
