1 lis 2022 · A total of 256 soil samples from 21 different countries and 35 publications containing both textural (sand, silt and clay percentages) and Atterberg limits data have been analyzed. The soils were classified according to traditional particle size criteria using the USDA texture triangle.
Soil Texture Calculator. Learn how to calculate a single point texture class based on percent sand, silt, and clay. Including the optional sand fractions will refine the calculation. Calculate and plot multiple texture classes based on percent sand, silt, and clay.
23 paź 2022 · The soil textural triangle is used to identify soil texture types. The proportions of particle types are found by suspending a sample in water (put soil and water in a jar and shake it), allowing the components to settle (this can take up to 24 hours), and then measuring the layers formed.
Segitiga tekstur tanah dapat digunakan dengan mengetahui kandungan fraksi pasir, debu, dan liat. Misalkan suatu tanah mengandung 50% pasir, 20% debu, dan 30% liat. Dari segitiga tekstur dapat dilihat bahwa sudut kanan bawah segitiga menggambarkan 0% pasir dan sudut kirinya 100% pasir.
Dikatakan bertekstur lempung bila perbandigan pasir, debu, dan liatnya seimbang. Penentuan tekstur tanah di laboratorium dilakukan dengan analisis secara mekanik atau granulair dengan menentukan prosentase fraksi penyusun tanah. Berdasarkan segitiga USDA dibedakan menjadi 12 kelas tekstur tanah, seperti terlihat dalam tabel berikut : Tabel 2.

Gambar 1 Diagram segitiga tekstur tanah. Tanah lempung dan debu memiliki ciri-ciri berukuran halus, biasanya berbentuk seperti mika dan liat bila lembab dan memiliki daya serap (air, gas, hara, dan garam laut) tinggi. Selain itu, lempung dan debu dalam tanah menentukan kehalusan teksturnya serta gerakan air dan udara.
