Good sources of quick nitrogen are corn gluten meal and a synergistic combination of composted manure and alfalfa meal or pellets (sold as unmedicated calf manna). Mature compost offers more ...
Organic fertilizers are fertilizers that are naturally produced. [1] ... Grain meals can be made of corn gluten, alfalfa, cottonseed, or soybean.
The Earth's atmosphere contains over 78 percent nitrogen. Plants called legumes, including the agricultural crops alfalfa and soybeans, widely grown by farmers, harbour nitrogen-fixing bacteria that can convert atmospheric nitrogen into nitrogen the plant can use.
