How to read the number

The roads air and water take. Few pores: roots smother, water ponds, the hoe shines. Crumbs make pores. Compaction, wet tillage and thin OM close the roads Easy to mix up: Bulk density is weight; porosity is empty space. When one rises the other falls Porosity is the pore space.

What it looks like in the field

The roads air and water take. Few pores: roots smother, water ponds, the hoe shines.
