Abstract
A method for producing stable fertilizer by nano-carbon sol comprising: the pH of the nanometer carbon sol is <2.2, conductivity is 2800-3400 μs/cm; the content of carbon content of nano-carbon sol reaches 0.57-2%, particle size<100 nm, potential difference is −30-35 mv; The addition of nano carbon sol as synergist in nitrogen-containing fertilizers was 1.05 to 10% of the weight of nitrogen-containing fertilizers. Nano-carbon sol is added in the growing process of crops, or in the production process of nitrogen-containing fertilizers. The invention can make fertilizer nutrient supply stable and increase yield obviously: there was no lack of fertilizer in the late stage of crop, and the average yield increased by 5-18%; the utilization rate of fertilizer can be improved. The nitrification inhibition rate of the present invention reaches 6.3-6.8%, the inhibition rate of nitrification of nitrogenous compound fertilizer was 19-25%, it is an environmental friendly fertilizer synergist, and it will not cause any residual damage to soil crops.
