Types of Organic Soil Amendments
Year-Old Manure: Very important that it’s rotted so it doesn’t burn the roots of some plants or cause them to grow enormously but not produce any flowers, fruits or vegetables.
Finished Compost: “Black Gold” Finished compost does not have a rotted odor, rather it should smell like earth. It should be dark in color and be completely broken down with no chunks of decomposing material.
Store-Bought Organic Fertilizer: Really read the label on bags of “organic” fertilizers before buying them. Look for N-P-K ratios that are lower than 8 and stay away from ingredients such as superphosphate, nitrate, urea, phosphoric, ammonium, & muriate. (Garden Smarts)
