A soil amendment is any material added to a soil to improve its physical properties, such as water retention, permeability, water infiltration, drainage, aeration and structure. The goal is to provide a better environment for roots. To do its work, an amendment must be thoroughly mixed into the soil.
On clay soils, soil amendments improve the soil aggregation, increase porosity and permeability, and improve aeration, drainage, and rooting depth.
On sandy soils, soil amendments increase the water and nutrient holding capacity. There are two broad categories of soil amendments: organic and inorganic. Organic amendments include compost, manure, peat moss, wood chips and sawdust. Inorganic amendments include pumice and lava, vermiculite, perlite, pea gravel and river sand.
|3/8"- Pumice Fines||PUMC Pumice is solidified foam that forms from lava rich in gases. It has numerous pores in the form of bubbles and irregular cavities that absorb moisture. Our pumice is sized at ½” minus and contains about 50% fines. Pumice is a light weight stone used to amend garden soil and provides improved aeration and moisture retention while maintaining a reduced soil weight.|

|Black Lava Sand||LAVAS Sourced from northern Arizona our Black Lava Sand is sized at 3/16” minus and fines. Lava Sand is a porous light weight rock consisting primarily of Plagioclase, Olivine, and Augite. It is primary used in gardening as a light weight aggregate. It is used to loosen and aerate the soil. Its porous structure will help break up heavy clay soil to allow drainage while providing moisture retention.|

|Pecan Shells||PCANS Pecan Shells are a richly colored red-brown mulch used in landscaping and gardening. They help to conserve soil moisture and prevent unwanted growth. The shape of the shells interlock to resist blowing in the wind. They are acidic with a pH of 4.34 and have high concentrations of iron, sulfate, phosphate, zinc, copper, & manganese. As the shells break down and decompose over several seasons, they deposit these nutrients into the ground, helping to improve our alkaline soil.|

|Pine Mulch||PMULCH Pine Mulch is a finely screened ¼” pine wood mulch that is primarily used as as an insulating layer of organic material spread out on top of soil. Pine Mulch blankets topsoil to conserve moisture and can maintain a more even topsoil temperature. In thick enough layers it can be used to prevent weed growth. Pine Mulch can also be used in a decorative manner, giving plant beds a neat, landscaped appearance.|
