Combined Application of Inorganic Fertilizer and Chicken Manure Compost Increases Maize Yield through Improved Soil Fertility

초록

Integrated management of soil nutrients and organic matter is critical for sustainable food production and soilhealth under climate change. Therefore, the appropriate combination of inorganic and organic fertilization isnecessary for sustainable agriculture that can ensure food production with high quality. The aim of this studywas to investigate the combined effects of different inorganic fertilizer (IF) application rates with organicfertilizer (OF; compost) on maize growth performance and soil chemical properties under field conditions. The fertilization treatments were: no fertilizer application; IF 100%; IF 75% + OF 25%; IF 50% + OF 50%; IF25% + OF 75%; OF 100%; IF 100% + OF 100%. The application of organic fertilizer to the soil increased soilorganic matter and available P in proportional to the amount of organic fertilizer applied. The combination ofinorganic and organic fertilizers significantly increased maize grain yield. The average maize grain yield forthe combined application of inorganic and organic fertilizers (IF 25% + OF 75%) was 35% higher than that forIF 100% treatment. Our study shows that combined inorganic and organic fertilization could enhance soilfertility and organic carbon storage in soils while contributing to high crop productivity in agriculture.
