Segitiga tekstur tanah berdasarkan rasio relatif dari tiga kategori utama tekstur tanah

Tekstur tanah adalah klasifikasi secara kualitatif mengenai kondisi suatu tanah berdasarkan tekstur fisiknya. Pengujian dan penerapan tekstur tanah diterapkan di lapangan maupun di laboratorium. Kategori utama dari tekstur tanah yaitu tanah berpasir, liat atau lempung, dan geluh atau lanau, berdasarkan distribusi ukuran partikel tanah yang didapatkan dengan pengayakan. Kualitas tekstur tanah yang didapatkan bisa digunakan untuk berbagai penerapan, misal komoditas pertanian yang cocok untuk ditanam hingga kondisi dan perubahan lingkungan.

Klasifikasi berdasarkan USDA

Jenis tanah	Diameter partikel
Liat	less than 0.002
Lanau	0.002–0.05
Berpasir sangat halus	0.05–0.10
Berpasir halus	0.10–0.25
Berpasir sedang	0.25–0.50
Berpasir kasar	0.50–1.00
Berpasir sangat kasar	1.00–2.00
