  • Effects of maize straw and its biochar application on


    Jul 01, 2019· The maize straw biochar used in the experiment was produced via slow pyrolysis of maize straw at Beijing United Pioneer Environmental Engineering Co., Ltd., China (Zhang et al., 2015a,b). The experiment was arranged in a completely randomized block design with three replicates. Each experimental plot was 104 m 2 (10.4 m × 10 m). Four treatments including unfertilized control (CK), mineral nitrogen, phosphorus and potassium fertilizers (NPK), NPK plus maize straw (NPKS), and NPK plus maize

  • Effects of N fertilization and maize straw on the dynamics


    Jul 01, 2018· 1. Introduction. Nitrogen (N) is the primary limiting nutrient for crop production in terrestrial ecosystems ().The productivity of agricultural crops strongly depends on high levels of fertilizer N applied to the soil (Alam et al., 2006; Raun and Johnson, 1999).However, excessive N application can cause significant ecological and environmental problems, such as increased production of N 2 O
