“…The spatial distribution of very high levels (>5 mg·kg −1 ) of available Zn was also uneven in both 2007 and 2017; that is in line with the result of Opfergelt et al (2017), who found that the distribution of micronutrients was affected by soil matrix, geomorphology and special fertilization measures [24]. In addition, the expansions of areas with high-levels of soil micronutrients were mainly caused by increases in fertilizer input and land-use changes [25]. The distributions of available Fe and Mn recorded a gradual increase from the southeast to the northwest in the study area in 2007 and 2017; these changes, being similar to the landscape distribution, were mainly affected by topography and soil type.…”

Information on the spatial variability of soil-available micronutrients is important for farming and soil management practices. As current knowledge of factors influencing soil available micro-nutrients in the long-term scales is limited, we analyzed 821 and 812 representative surface (0-20 cm) soil samples from five sub-catchments in the Ping Gu intermontane basin in Beijing, China in 2007 and 2017. The objectives of this study were to assess the temporal and spatial distribution characteristics of soil-available micronutrients (Cu, Zn, Fe and Mn) and their relationships with soil's chemical properties. The concentration of available Cu ranged from 1-2 mg·kg −1 distributing over a large area in 2007, but it was more than 2 mg·kg −1 in the hilly regions in 2017. The concentration of available Zn (>5 mg·kg −1 ) increased significantly from 2007 to 2017, and showed an uneven distribution. The distribution of available Fe and Mn decreased from the northeast to the southwest region of the study area between 2007 and 2017, this being consistent with the topography in this area. Soil's available P (AP) had a higher contribution to available Cu and Zn in different sub-catchments. In addition, soil pH had a significant negative influence on available Fe in sub-catchments 1, 2 and 3, and on available Mn in all sub-catchments, except for sub-catchment 4. Moreover, the effects of soil chemical properties on soil-available micronutrients increased in each sub-catchment from 2007 to 2017. We conclude that differences in soil properties and land-use types were the main reasons for the spatial variability of soil-available micronutrients in the Ping Gu intermontane basin.

“…Not surprisingly, we found the abundance of soil microorganisms in the surface layer increased significantly in OF treatments when compared with the unfertilized control. Our findings are comparable to numerous field studies that have documented microbial biomass and community composition to be strongly correlated with SOC (Choudhary et al, 2018;Guo, Han, Li, Xu, & Wang, 2019;Liu et al, 2015). However, the impact of long-term NPK fertilizer application on microbial community composition was minimal (Liu et al, 2015), except for fungi in NPK, we found no significant effect of NPK fertilization either alone or in combination with each other on the abundance of soil microorganisms.…”

“…This indicated that soil AK could be gradually depleted and K deficiency could become a constraint to increasing yields of consecutive crops grown without fertilizer application. The OF had the highest AK in 0to 20-cm soil depth than other treatments, this result is inconsistent with Choudhary et al (2018). Manure application provided extra K input, which likely contributed to increased wheat yields (Qin et al, 2015).…”

The effects of long-term fertilization on crop yield and soil property in maize (Zea mays L.)-wheat (Triticum aestivum L.) rotation of desalinized soils are limited. A long-term fertilization experiment was established in 1996 to compare the impact of single and mixed mineral (NPK), and manure fertilization on crop yields and soil properties. The long-term application of manure (OF) and N fertilizer significantly increased crop yields by the 129 and 42% of yield increase, respectively, over other chemical fertilizer application. Nitrogen fertilizer increased soil surface nitrate nitrogen (NO 3 −-N) while not affecting soil ammonium nitrogen (NH 4 +-N). Organic fertilizer significantly increased soil organic carbon (SOC, increased 68.7%), available phosphorus (AP, 97.4%), and available potassium (AK, 68.5%) compared with chemical fertilizer application. Inorganic fertilizer application has less impact on microbial community composition than manure. A complete NPK plus manure fertilization program is recommended for desalinized soils around the Bohai Sea to maximize crop yields and improve soil fertility.

“…Excessive use of inorganic fertilizers is a common practice to meet the nutrient need of high-yield varieties. Different long-term experiments have indicated that long-term continuous and excessive chemical fertilization degraded the soil quality and increased acidification, which resulted in poor crop sustainability [21,22].…”

“…The sustainable yield index (SYI) represents the actual yields over a long period. A higher sustainable yield index indicates that an area will produce an acceptable yield over the years through better cultivation practices [20][21][22]. SYI is a quantitative measure with which to assess the sustainability of an agricultural practice [23].…”

Long-Term Green Manure Rotations Improve Soil Biochemical Properties, Yield Sustainability and Nutrient Balances in Acidic Paddy Soil under a Rice-Based Cropping System

Cultivation of green manure (GM) crops in intensive cropping systems is important for enhancing crop productivity through soil quality improvement. We investigated yield sustainability, nutrient stocks, nutrient balances and enzyme activities affected by different long-term (1982–2016) green manure rotations in acidic paddy soil in a double-rice cropping system. We selected four treatments from a long-term experiment, including (1) rice-rice-winter fallow as a control treatment (R-R-F), (2) rice-rice-milkvetch (R-R-M), (3) rice-rice-rapeseed (R-R-R), and (4) rice-rice-ryegrass (R-R-G). The results showed that different GM rotations increased grain yield and the sustainable yield index compared with those of the R-R-F treatment. Compared with those of R-R-F, the average grain yield of early rice in R-R-M, R-R-R, and R-R-G increased by 45%, 29%, and 27%, respectively and that of late rice increased by 46%, 28%, and 26%, respectively. Over the years, grain yield increased in all treatments except R-R-F. Green manure also improved the soil chemical properties (SOM and total and available N and P), except soil pH, compared to those of the control treatment. During the 1983–1990 cultivation period, the soil pH of the R-R-M treatment was lower than that of the R-R-F treatment. The addition of green manure did not mitigate the soil acidification caused by the use of inorganic fertilizers. The soil organic matter (SOM), total nitrogen (TN) and total phosphorus (TP) contents and stocks of C, N and P increased over the years. Furthermore, GM significantly increased phosphatase and urease activities and decreased the apparent N and P balances compared with those in the winter fallow treatment. Variance partitioning analysis revealed that soil properties, cropping systems, and climatic factors significantly influenced annual grain yield. Aggregated boosted tree (ABT) analysis quantified the relative influences of the different soil properties on annual grain yield and showed that the relative influences of TN content, SOM, pH, and TP content on annual crop yield were 27.8%, 25.7%, 22.9%, and 20.7%, respectively. In conclusion, GM rotation is beneficial for sustaining high crop yields by improving soil biochemical properties and reducing N and P balances in acidic soil under double- rice cropping systems.
