Tekstur Tanah Berdasarkan Volume

Penetapan tekstur tanah dengan menggunakan persen volume dapat dilakukan dengan lebih sederhana dibandingkan dengan metode hidrometer. Prinsip penetapan berdasarkan persen volume ini juga berdasarkan pada kecepatan pengendapan. Dimana fraksi yang kasar atau pasir akan mengendap lebih awal (1 meniut) dan kemudian diikuti oleh fraksi debu sekitar 2 jam, dan sisanya adalah fraksi liat yang akan mengendap sekitar 48 jam kemudian. ...
