Abstract
The application of nanomaterials in agriculture has considerable advantages, but its impact on the dynamic change of soil nutrients is still unclear. In the two-year experiment, the effects of nanocarbon (NC) and nano calcium carbonate (NCC) on the dynamic changes of soil nutrients in the wheat field were studied by setting the ratio of different nanomaterials and fertilizers. All treatments with NC and NCC applications positively affected soil nutrient effectiveness at 0–35 d after wheat anthesis, and the effect of NC+NCC was more significant. At 35 days after anthesis, soil available phosphorus (P), available potassium (K), organic matter (OM), and alkaline hydrolysis nitrogen (N) were elevated by 77.9%, 21.9%, 11.7%, and 7.0%, respectively, in the first year and 44.3%, 10.2%, 9.0%, and 7.6%, respectively, in the second year of treatment with 100% CF (complex fertilizer) + 50% NC + 50% NCC compared with control. The treatment with reduced fertilizer application also demonstrated a greater advantage. At 35 d after anthesis, 70% CF + 35% NC + 35% NCC had 54.3%, 11.5%, 8.4%, and 5.8% higher soil available P, available K, OM, and alkaline hydrolysis N, respectively, compared with the control, and 41.05%, 6.4%, 7.8%, and 5.4% higher the following year, respectively. In acidic soils, positively charged NC and NCC have a lasting effect on maintaining soil nutrients by adsorbing acid ions. Therefore, NC and NCC with compound fertilizer have favorable effects in maintaining soil nutrient content and improving fertilizer utilization.
