INFILTRASI DAN PENETRASI AIR DALAM TANAH

Infiltrasi Air : Masuknya air ke dalam tanah Faktor-faktor yang mempengaruhi: Tekstur tanah Kandungan-awal lengas tanah Kerak permukaan (structure, etc.) Soil cracking Praktek pengolahan tanah Metode aplikasi air (e.g., Basin vs. Furrow) Suhu air.

Infiltrasi Kumulatif vs. Tekstur Tanah

Laju Infiltrasi vs. Waktu Untuk tekstur tanah yang berbeda

Laju Infiltrasi dan Tekstur Tanah

Laju infiltrasi vs. Laju irigasi konstan

Laju infiltrasi vs. Laju irigasi beragam

Kedalaman Penetrasi Air 1.Can be viewed as sequentially filling the soil profile in layers 2.Deep percolation: water penetrating deeper than the bottom of the root zone 3.Pencucian : transport of chemicals from the root zone due to deep percolation
