Long-term cattle manure application to saline-sodic soil increases maize yield by decreasing key obstacle factors in the black soil region of Northeastern China

International Journal of Agricultural and Biological Engineering 2023年第6期16卷 176-183页

作者： Fei Yu Shuo Zhao Ying Zhao Yong Wang Cheyu Zhai Rui Zhong Juan Zhang Qingfeng Meng School of Resources and Environment Northeast Agricultural UniversityHarbin 150030China

Poor soil physical properties, serious salinization and low soil nutrients are the limiting factors for crop yield in saline-sodic soil. Long-term cattle manure application is an important measure that can affect the physicochemical properties and increase the maize yield of saline-sodic soil. This experiment included five treatments according to the history of cattle manure application: a control treatment with no cattle manure (CK) and treatments with cattle manure application for 14 years (14 a), 17 years (17 a), 20 years (20 a), and 25 years (25 a). The results indicated that compared with the CK treatment, long-term cattle manure application to saline-sodic soil resulted in significant increases in soil organic matter (SOM), soil total nitrogen (TN) and available nutrients at the 0-20 cm and 20-40 cm depths (pmaize yield gradually increased over time from 8690 kg/hm2 in the CK treatment to 14 690 kg/hm2 in the 25a treatment. There were significant differences among all treatments (pmaize yield in the saline-sodic soil, especially for soil ρb.

Impact of climate change on maize yield in China from 1979 to 2016

Journal of Integrative Agriculture 2021年第1期20卷 289-299页

作者： WU Jian-zhai ZHANG Jing GE Zhang-ming XING Li-wei HAN Shu-qing SHEN Chen KONG Fan-tao Agricultural Information Institute Chinese Academy of Agricultural Sciences/Key Laboratory of Agricultural Big Data Ministry of Agriculture and Rural Affairs Beijing 100081P.R.China Institute of Special Animal and Plant Sciences Chinese Academy of Agricultural SciencesJilin 130112P.R.China

Climate change severely impacts agricultural production, which jeopardizes food security. China is the second largest maize producer in the world and also the largest consumer of maize. Analyzing the impact of climate change on maize yields can provide effective guidance to national and international economics and politics. Panel models are unable to determine the group-wise heteroscedasticity, cross-sectional correlation and autocorrelation of datasets, therefore we adopted the feasible generalized least square(FGLS) model to evaluate the impact of climate change on maize yields in China from 1979–2016 and got the following results:(1) During the 1979–2016 period, increases in temperature negatively impacted the maize yield of China. For every 1℃ increase in temperature, the maize yield was reduced by 5.19 kg 667 m^–2(1.7%). Precipitation increased only marginally during this time, and therefore its impact on the maize yield was negligible. For every 1 mm increase in precipitation, the maize yield increased by an insignificant amount of 0.043 kg 667 m^–2(0.014%).(2) The impacts of climate change on maize yield differ spatially, with more significant impacts experienced in southern China. In this region, a 1℃ increase in temperature resulted in a 7.49 kg 667 m^–2 decrease in the maize yield, while the impact of temperature on the maize yield in northern China was insignificant. For every 1 mm increase in precipitation, the maize yield increased by 0.013 kg 667 m^–2 in southern China and 0.066 kg 667 m^–2 in northern China.(3) The resilience of the maize crop to climate change is strong. The marginal effect of temperature in both southern and northern China during the 1990–2016 period was smaller than that for the 1979–2016 period.

Chemical fertilizers could be completely replaced by manure to maintain high maize yield and soil organic carbon(SOC)when SOC reaches a threshold in the Northeast China Plain

Journal of Integrative Agriculture 2017年第4期16卷 937-946页

作者： LI Hui FENG Wen-ting HE Xin-hua ZHU Ping GAO Hong-jun SUN Nan XU Ming-gang National Engineering Laboratory for Improving Quality of Arable Land Institute of Agricultural Resources and Regional PlanningChinese Academy of Agricultural Sciences College of Environmental and Resource Sciences Henan Agricultural University Department of Microbiology and Plant Biology University of Oklahoma College of Resources and Environment Southwest University Institute of Soil and Fertilizer Jilin Agricultural Academy of Sciences

The combined use of chemical and organic fertilizers is considered a good method to sustain high crop yield and enhance soil organic carbon （SOC）, but it is still unclear when and to what extent chemical fertilizers could be replaced by organic fertilizers. We selected a long-term soil fertility experiment in Gongzhuling, Northeast China Plain to examine the temporal dynamics of crop yield and SOC in response to chemical nitrogen, phosphorus, and potassium （NPK） fertilizers and manure, applied both individually and in combination, over the course of three decades （1980-2010）. We aimed to test 1） which fertilizer application is the best for increasing both maize yield and SOC in this region, and 2） whether chemical fertilizers can be replaced by manure to maintain high maize yield and enhance SOC, and if so, when this replacement should be implemented. We observed that NPK fertilizers induced a considerable increase in maize yield in the first 12 years after the initiation of the experiment, but manure addition did not. In the following years, the addition of both NPK fertilizers and manure led to an increase in maize yield. SOC increased considerably in treatments with manure but remained the same or even declined with NPK treatments. The increase in maize yield induced by NPK fertilizers alone declined greatly with increasing SOC, whereas the combination of NPK and manure resulted in high maize yield and a remarkable improvement in SOC stock. Based on these results we suggested that NPK fertilizers could be at least partially replaced by manure to sustain high maize yield after SOC stock has reached 41.96 Mg C ha^-1 in the Northeast China Plain and highly recommend the combined application of chemical fertilizers and manure （i.e., 60 Mg ha^-1）.
