Change of Tillage Layer Thickness of Farmland in Anhui Province of Eastern China

Tillage layer thickness (TLT) of farmland could be regarded as one of physical indexes in assessing soil productivity and quality. In recent years, tillage layer shallowing was found in China in various regions, mainly due to the adoption of non-tillage or rotary tillage practices, but only little rough and non-quantitative information is available so far on the issue. This research took Anhui, a typical agricultural province in Eastern China as an example and compared the TLTs of 87 typical profiles on provincial scale and 210 on county scale from 1980s to 2010s. The results showed that TLTs of 3.7% and 17.2% of samples in 1980s and 2010s respectively were larger than 20 cm. From 1980s to 2010s the mean TLT increased from 16.3 to 17.4 cm on the provincial scale and from 15.0 to 15.5 cm on the county scale respectively. In the middle and southern regions the mean TLTs increased by 0.4-0.7 cm on the provincial scale and 0.3-3.2 cm on the county scale respectively, but decreased by 2.0 cm in northern region on the county scale. The mean TLT increased by 0.8 cm for paddy-field and 1.4 cm for dry-land on the provincial scale. TLT was influenced comprehensively by the factors of soil texture, the depth of rotary tillage and the farming positivity of the farmers. Generally, TLT of farmland with coarse soil texture was higher than that of farmland with fine soil texture, in 1980s TLT in region of poor-economic condition usually was deeper than in region of good-economic condition, and the adoption of rotary tillage led widely TLTs of farmlands to about 15 cm in 2010s.

The prevalence of soil transmitted helminths and its infuential factors in Shandong Province, China: an analysis of surveillance data from 2016 to 2020

Background Soil-transmitted helminths(STHs)were previously endemic in Shandong Province,China.This study aimed to analyze the STHs prevalence trend and the natural,social,and human cognitive and behavioural factors infuencing the discrepancies between high and low infection levels from 2016 to 2020 in Shandong Province in eastern China.Methods STHs surveillance data of Shandong Province from 2016 to 2020 were obtained from China Information Management System for Prevention and Control of Parasitic Diseases.STHs infections were detected by modifed Kato–Katz method.Comprehensive information on the natural and social factors,STHs-related knowledge and behaviours were collected through questionnaire surveys.Retrospective spatial scan analysis was performed using SaTScan v10.1 to evaluate any identifed spatial clusters of STHs infection for statistical signifcance and Bayes discriminant analysis was used to discriminate the high or low infection groups of the villages.Results In total,72,160 participants were involved in our survey from 2016 to 2020.The overall STHs prevalence rate was 1.13%,with the eastern region of Shandong Province having the highest rate(2.02%).The predominant species was T.trichiura,with the prevalence rate of 0.99%and the≥70-year age group possessed the highest rate of 2.21%.The STHs prevalence rate showed an annual linear downward trend from 2016 to 2020(χ_(trend)^(2) =127.600,P<0.001).Respondents aged≥60 years had the lowest awareness level of STHs-related prevention knowledge(all P<0.05),and were the most likely to adopt the practice of fertilizing with fresh stool(χ^(2)=28.354,P<0.001).Furthermore,the southern region demonstrated the highest temperature and rainfall level and the lowest GNP and annual net income per capita(all P<0.05).Conclusions There is a remarkable declining in STHs prevalence in Shandong Province from 2016 to 2020.However,the prevalence rates of STHs especially T.trichiura in the southern and eastern regions were still high,and the elderly were more susceptible to be infected with STHs owning to their low awareness level of STHS-related prevention knowledge and high adoption rate of dangerous production and living behaviours.Integrated approaches of health education,environment improvement and behaviour change should be strengthened to obtain a further reduction of STHs prevalence in China.
