Study on the General Situation and Trend of Pesticide in Global Soil System

Abstract

Based on the core collection database of the Web of Science (WoS), the related papers research on pesticides in global soil system were analyzed. The development history, present situation and dynamic development trend of pesticides in soil system all over the world were analyzed by using the CiteSpace knowledge map analysis tool. The results showed that it was an active period of rapid development after 21 century in this field with number of annual papers was 143.95. The institution with the greatest number of papers, the highest total global citation frequency and the highest H index was the Chinese Academy of Sciences; the researchers with the greatest number of papers and the highest total global citation frequency were Qi S.H. from the College of the Environment, China University of Geosciences (Wuhan) and Kookana R.S. from the Commonwealth Scientific and Industrial Research Organization, respectively; and the highest citation per paper was Jones K.C. from Lancaster University. The hotspots in this field mainly were pesticide degradation, the content of pesticide in the water, pesticide residues, organochlorine pesticides, pesticide sorption and so on. The research shows that the effect of pesticides on soil ecosystem and the evaluation of ecological toxicity, the remediation methods of pesticides in soil, the management and control strategy of pesticide application in soil will be paid more attention to in the future.

The Synergy of Fertilizer and Pesticide Reduction in China: Measurement and Driving Factors

“…A reason for this finding is that China's major agricultural provinces are the main regions of grain production and bear the responsibility for ensuring China's food security. Another reason is that China's major agricultural provinces are excessively cautious about the practice of reducing fertilizer and pesticides due to concerns about whether the reduction of fertilizer and pesticides will lead to a reduction in grain yield [19]. At the regional level, SFPR's influencing factors show some similarities and differences in eastern, central, western, and northeastern China.…”

“…Also, the input structure of elements is different in plain areas, hills, and mountains [29]. Some major grain-producing areas even have to bear the responsibility for national food security [19]. Therefore, each province should set fertilizer and pesticide reduction targets according to its own resource endowment characteristics and national strategic requirements, as well as different regions, crops, and time periods.…”

“…These results show that fertilizer usage will continue to decline in China [18]. In order to maintain the reduction of fertilizer use in China from 2020 to 2025, Li et al [19] also pointed out that the Chinese government should change its strategy and focus more on the intensity of fertilizer use per unit area than its total amount and on grain crops rather than cash crops. Some studies also conducted empirical research on large survey data of smallholders in China and found it necessary to strengthen the input of fixed assets such as machinery to reduce fertilizer usage by improving its efficiency [20,21].…”
