Special Issue Information

Dear Colleagues,

Agricultural soil pollutants, such as heavy metals, persistent organic pollutants, antibiotic resistance genes and micro/nano-plastics have become a global environmental problem. The constant input and long-term existence of these pollutants leads to the deterioration of soil quality and the destruction of soil structure and its normal function, thus adversely affecting crop growth. More significantly, these pollutants in the soil can be absorbed by root systems and accumulate in the edible parts of crops, finally entering the human body through the food chain and posing a potential threat to human health. However, due to its long-term, cumulative and hidden characteristics, agricultural soil pollution is often overlooked. Therefore, it is very important to understand the impact of emerging pollutants on soil microecology, crop growth and quality. The decrease in pollutant bioavailability and the block of their transmission into crops has also become a key concern. We are welcoming high-quality research papers and review articles that focus on emerging contaminants in agriculture soil and their effect on soil ecosystems, crop growth and human health, as well as polluted soil treatment technology. The following are some examples of topics that could be addressed in this Special Issue:

  1. The sources, transport and transformation of emerging pollutants and their effects on soil quality and micro-ecosystems;
  2. An assessment of the impact of emerging pollutants on the growth, development and quality of crops and their impact on human health;
  3. Preparation and performance research of contaminated soil remediation materials;
  4. Carbon-neutral soil pollution prevention and control; agronomic, management, engineering and other measures.

Combination of Water-Saving Irrigation and Nitrogen Fertilization Regulates Greenhouse Gas Emissions and Increases Rice Yields in High-Cold Regions, Northeast China

Increased rice production, which benefitted from cropping areas expansion and continuous N applications, resulted in severe increases in greenhouse gases (GHG) emissions from 1983 to 2019 in Heilongjiang Province, China. Therefore, field trials were performed in the high-cold Harbin region, Northeast China, to determine the efficiency of incorporating water regimes with N fertilization in minimizing the impact of rice production on GHG emissions. Two water-saving irrigation strategies, intermittent irrigation (W1) and control irrigation (W2), were used relative to continuous flooding (W0), and we combined them with six fertilized treatments. Our results demonstrated that W1 and W2 significantly decreased seasonal CH4 emissions by 19.7–30.0% and 11.4–29.9%, enhanced seasonal N2O emissions by 77.0–127.0% and 16.2–42.4%, and increased significantly yields by 5.9–12.7% and 0–4.7%, respectively, compared with W0. Although trade-offs occurred between CH4 and N2O emissions, W1 and W2 resulted in significant reductions in global warming potential (GWP). Moreover, low N rates (<120 kg N ha−1) performed better in GWP than high N rates. N fertilization and irrigation regimes had remarkable effects on rice yields and GWP. In conclusion, the incorporation of W1 and a N application under 120 kg N ha−1 could simultaneously mitigate GWP while enhancing production in black soils in high-cold Northeast China. Full article

Dynamic Changes in Soil Phosphorus Accumulation and Bioavailability in Phosphorus-Contaminated Protected Fields

Soil phosphorus accumulation resulting in a high risk of phosphorus pollution is due to high multiple vegetable cropping indexes and excessive fertilizer input in protected fields. Therefore, this study explored the bioavailability of soil-accumulated phosphorus to improve fertilization and reduce the risk of soil phosphorus contamination in protected fields. A field trial was performed in Yanbian Prefecture, China to study the phosphorus bioavailability after continuous spinach planting without phosphate fertilizer applications. Results indicated that with increasing numbers of planting stubbles, soil inorganic phosphorus and occluded phosphorus changed little, while water-soluble and loose phosphorus, aluminum-phosphate, iron-phosphate, and calcium-phosphorus decreased first and then increased. Soil available phosphorus declined linearly. For planting spinach in protected fields, the threshold of soil phosphorus deficiency is 200 mg kg−1. A soil phosphorus supply potential model was established between x (the soil available phosphorus) and y (the numbers of planting stubbles): y = 6.759 + 0.027x, R = 0.99, which can be used to predict how planting stubbles are needed to raise the soil available phosphorus above the critical value of phosphorus deficiency for spinach. These results will provide the theoretical guidance for rational phosphorus fertilizer applications and control agricultural, non-point pollution sources in protected fields. Full article
