Influence of N-15 labelled urea and azotobacter on corn yield and nitrogen budget as affected by organic matter

Abstract

As sandy soils of Egypt are poor in their chemical and physical properties, their fertilization with chemical or biological fertilizer is essential. The reported greenhouse experiment was conducted, using sandy soil of Egypt to evaluate the impact of urea fertilizer, applied alone combined with nitrification inhibitors (DCD) or (N-serve) on (corn yield and N-losses) as compared with inoculation with azotobacter under organic matter treatment as soil amendment. Total dry matter was recorded, while N-uptake by corn, and N-recovery due to inoculation with azotobacter was determined using N-15 dilution technique. Data obtained indicated that, application of DCD or N-serve with urea increased corn dry matter weight as well N-15 recovery. Significant increase in N-recovery was obtained due to nitrification inhibitor application and azotobacter inoculation. N-15 losses were reduced due to application of DCD and N-serve from 45% and respectively. Use of bio fertilizers and nitrification inhibitors could play an important role in corn production in sandy soil, as well as decrease the losses of applied N-fertilizers. fig., 3 tabs.
