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.
|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.|

|14-38PUMC 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. This product is sourced from northern New Mexico and sized from 1/4" - 3/8” and containing a small amount 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.|

|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.|

|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.|

|CCHIP Coir is often used as the primary substrate for potting and raised bed gardens. The main advantage of coir is its ability to have a high water-holding capacity while providing a high level of aeration and good drainage. Another advantage is that coir also has a neutral pH of 5.5-6.2. The coco husks are all sourced from trees grown at least 5 miles inland from the ocean and are rinsed in fresh water. The inland trees absorb less salt water and the fresh water cleans and leeches the husks. Coco coir is free of bacteria, plant disease, fungi, weeds, and pathogens and also naturally inhibits infection from pythium (plant parasites) and phytophthora (water mold).|
