2. Bark. Is easy to mix into the soil. Low in salinity and very long lasting. This is a dense material that can be used in garden soil, container planting and also for orchids. Poor nitrogen and nutrient holding.

3. Fir Sawdust. This granular material works into the soil well and lasts a long time. Low salinity .Great for soil and containers. Also low in nitrogen and nutrient holding capability.

5. Hypnum Peat Moss. It has a fibrous texture which is more variable than  peat moss. Contains more nitrogen and is less expensive than peat moss. Best uses are in containers and fern baskets and in the soil. High in nitrogen and nutrient holding.

6.  Sedge Peat. Has a variable fibrous texture. May be higher in salinity and cheaper than Sphagnum. Great for use in soil in a rainy climate. Good nitrogen and nutrient holding.

7. Oak Leaf Mold.  This mix may contain leaves and twigs. Adds to soil fertility in a container mix. It is useful as a seed starter  mix. Contains ample nitrogen and other useful nutrients.

8. Dairy Manure. This amendment is moderately saline and must thoroughly decomposed. Has a strong odor. Great as a conditioner in sandy soils and as a mulch. This low grade fertilizer needs no additional nitrogen and holds nutrients well. May be free for the hauling in some areas.

13. Almond Hulls. Needs to compost first because big chunks decompose slowly. Available only where almonds are processed. Low salinity. Garden soil conditioner. High in nitrogen and potassium (potash), but poor in nutrient holding.

14. Rice Hulls. Very cheap where available. Easy to mix into garden soil. Loses much in volume when rotted. High in potassium. Very low in nitrogen and poor nutrient holding.


15. Cocoa Bean Hulls. Has a good scent and is a low grade fertilizer and amendment to your garden soil. Contains nitrogen, phosphorus, and potassium in low amounts. Good nutrient holding.
