Nitrogen

Alfalfa Meal

2% to 3% N, .7% P, 2.25% K. Lasts 3 to 4 months. Use up to 19 lbs (163/4 qt)/100 sq ft. A quick-acting source of nitrogen and some potassium. (If not organic, it can contain methoxichlor pesticide residues.)

Fish Meal

9% to 10.5% N, 6% P, 0% K. Lasts 6 to 8 months. Use up to 5 lbs (3% qt)/100 sq ft. Good combined nitrogen and phosphorus source. (Caution: Some can contain significant amounts of toxic heavy metals.)

Note

Remember that too much nitrogen in your soil can cause the soil's all-important organic matter to break down too quickly.
