The intensive development of the Yellow River Delta has caused huge transportation of non-point pollutants into the Bohai Sea. The rapid deposition of nitrate in the estuary delta was driven by heavy rainfall and human activities such as excessive use of nitrogen fertilizers, rapid urbanization, and livestock waste discharge.

Balancing agricultural income and environmental impact by adjusting the structure and scale of circular agriculture is becoming increasingly important. This paper built a multi-objective linear programming model based on greenhouse gas emission and agricultural product income and then optimized the structure and scale of circular agriculture using Beiqiu Farm as a case study. The optimization made full use of straw, manure and fodder, but also minimized soil nitrogen loss.

Nitrogen and salinity limit crop yield and net economic benefit in coastal saline-alkali soils. Binary quadric surface equations can be used to optimize wheat-corn cropping under saline and nitrogen conditions. Nitrogen addition based on environmental and farmers’ benefits was reduced by 40.4% and 33.9% comparing to traditional dose. Area-specific nitrogen application strategy is needed in coastal saline soils in China.

Farmland plastic pollution is increasing with the use of agricultural mulch film. An empirical study focused on smallholder farmers with national representative samples. National representative micro-level data was used to explore the effect of village regulations. Village regulations have significant direct and indirect positive effects on mulch film recycling.

Discarding waste pesticide bottles are causing environmental problems in rural China. 48.80% of households disposed of waste pesticide bottles in situ in rural China. The measures from government and market had positive effect on proper disposal. Soft constraints did not show significant effect. Synergies between the different policies have not yet been achieved.

Mismanagement of mulch film is causing environmental problems in rural China. National representative micro-level data was used to explore influencing factors of cognition. Half of farmers think that the agricultural mulch film can pollute farmland. The attitude, subjective norm, perceived behavioral control and household characteristics affect cognition. Pay attention to village regulations, not just formal institution.

The selection of mulch film thickness is decisive for the clean utilization of mulch film. Nationally representative data were used to analyze mulch film thickness selection. The selection of mulch film thickness is influenced by market factors and farmers’ product cognition. It is beneficial to strengthen subjective norms of farmers and improve farmland property rights.

Mulch film itself is not the primary source of MMPs in terms of abundance. Use history of mulch films was inversely correlated to the particle size of MMPs. Use history of mulch films was positively correlated to the abundance of MMPs. Questionnaire survey and soil sampling were integrated properly for MMPs pollution.
