Abstract
The present invention relates to environment-friendly, synergistic carbon-nano complex fertilizers comprising carbon-containing-fertilizer. The complex fertilizers comprise carbon nanomaterials, which have the particle size in a range from 5 nm to 200 nm and particularly 5 nm to 100 nm, and optional ammonia stabilizer or nitric acid reductase inhibitor. The weight ratio of the carbonic fertilizer and the carbon nanomaterials is in a range from 100:0.1 to 100:1. The weight ratio of the carbon-containing-fertilizer and the ammonia stabilizer or nitric acid reductase inhibitor is in a range from 100:0.1 to 100:1. Said carbon-containing-fertilizer is ammonium bicarbonate, urea, or a combination thereof. The complex fertilizers show synergistic emission reduction. The present invention also relates to compound fertilizers, which comprise said complex fertilizer and organic fertilizer.
