Nitrogen fertilizer form and application rate jointly govern the ecological stoichiometric characteristics of plants, soils, and microorganisms in perennial cultivated grasslands.
To elucidate the regulatory mechanisms by which nitrogen fertilizer form and application rate affect the carbon, nitrogen, and phosphorus (C:N:P) stoichiometric characteristics of the plant-soil-microbe system in perennial cultivated grasslands, this study used a mixed sward of Festuca sinensis Keng ex E.B.Alexeev cv....
