“…According to the analysis of long-term fertilization experiments in China (Zhang et al, 2019b), the average yield of corn increased by 2015 kg ha −1 when chemical fertilizers were combined with organic fertilizers. In this research study, the fertilization method was optimized, and the maize grain yield under shallow and deep applications of organic fertilizer remained stable or showed a steady increase over the years of fertilization.…”

Through a long-term micro-area positioning experiment (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017), the precise fertilization locations of spring maize (Zea mays L.) in Jilin, China, were investigated using an embedded cement bucket pot. The effects of different fertilization placements and additional application of organic manure on maize yield, biomass, grain nutrient uptake, and soil fertility were examined. Six treatments were designed: base fertilizer + topdressing shallow application (BF 1 TD 1 ); base fertilizer deep + topdressing shallow application (BF 2 TD 1 ); base fertilizer + topdressing deep application (BF 1 TD 2 ); base fertilizer deep + topdressing deep application (BF 2 TD 2 ); base fertilizer + topdressing + organic manure shallow application (BF 1 TD 1 + OS); and base fertilizer + topdressing shallow application + organic manure deep application (BF 1 TD 1 + OD). After 12 years of continuous experimentation, the findings revealed that BF 2 TD 2, BF 1 TD 1 + OS, and BF 1 TD 1 + OD exhibited 10.59 %, 25.17 %, and 29.34 % higher average yields than BF 1 TD 1 , respectively. Deep topdressing was more beneficial in increasing maize yield and nutrient accumulation, and additionally, increasing the use of organic fertilizer enhanced plant biomass and nutrient uptake. Over the 12 years considered, the soil organic matter in the 0-20 cm and 20-40 cm layers increased by 45.96 % and 80.61 %, respectively, and the soil pH increased from 0.38 to 0.48. In general, the deep application of organic manure was more beneficial for soil retention as it can increase soil fertility in the 0-40 cm layer. Considering the high yield and nutrient absorption and utilization of maize, technical advancement for soil fertilizer in whole-field tillage layers was crucial.

“…Knowledge of soil quality is very important for evaluating the positive or negative effects of agricultural practices, integrating the results obtained into the management process, promoting sustainable agricultural practices, and monitoring the changes in soil indicators during the growing season [68]. According to Zhang et al [69], mineral fertilization alone has no effect on certain parameters such as Nt in the short term, but the combination of chemical fertilizers with organic amendments can increase Nt content. In addition, Liu et al [70] indicated that soil organic matter, Nt content, and pH did not change with short-term application of mineral and organic fertilizers.…”

Agronomic practices can have a negative impact on soil health and quality and ecosystem resilience. The objectives of the study were (1) to evaluate the soil chemical properties and microbial abundance under short-term application of organic and mineral fertilizers and different cultivated crops and (2) to observe the antifungal efficacy of microorganisms isolated from the studied soil. A field trial was conducted in the 2021–2022 period on a preluvosoil-type soil in four randomized blocks with eight fertilizer treatments based on manure compost (MC) and MC + mineral fertilizer (V1—control-soil; V2—NPK only; V3—15 t/ha MC; V4—15 t/ha MC + NPK; V5—30 t/ha MC; V6—30 t/ha MC + NPK; V7—60 t/ha MC; and V8—60 t/ha MC +NPK) and four crops (winter wheat—Triticum aestivum L., maize—Zea mays L., soybean—Glycine max L., and a mixture of perennial grasses and legumes). In almost all treatments, the soil pH decreased during the summer–autumn period. The organic carbon (Corg) and humus contents increased compared to the initial state of the soil after the application of different doses of MC and MC + NPK fertilization in almost all treatments. The microbial load of the soil was influenced by the fertilization regime and crop species, but there were no significant differences between the variants. The highest bacterial load was recorded in soil cultivated with a mixture of perennial grasses and grain legumes, i.e., in the variant with 15 t/ha MC, followed by soil cultivated with maize and fertilized with 30 t/ha and 60 t/ha MC. A higher number of fungi was observed in the mixture of perennial grasses and legumes, and Rhizobium population was higher, especially in the winter wheat plots, despite the fertilization regime. The antifungal efficacy of the microorganisms isolated from the samples was medium to low, except in the winter wheat experiment, where the efficacy against Fusarium culmorum was medium to high and against other pathogens was medium. In the other crops within the experiment, the antagonistic activity of the soil microorganisms was medium to low.

“…This echoes the view in the previous chapter that the maize yield, biomass and P uptake of P0 treatment initially increased and then gradually decreases with the increase of planting years. The depletion of P through interspecific interactions may increase soil demand for exogenous P (Zhang et al 2019;Zhou et al 2023). Therefore, improving the basic fertility of the soil can reduce the dependence of maize yield on exogenous fertilizers, and thus reduce the application amount of fertilizers.…”

Aims Studying the effects of maize and soybean intercropping for improving maize yield, and maintaining stability of maize yield under different phosphate (P) application rates in red soil is important for promoting the maize productivity, improving soil fertility and optimizing P nutrient management in southwest China. The objective of this study was to evaluate the dynamic changes of maize yield, yield stability and soil fertility under monoculture and intercropping maize with different P application rates. Methods A six-year field experiment was conducted from 2017 to 2022 to investigate the effects of maize intercropping with soybean on the yield stability and sustainability of maize according to the changes in maize yield, biomass, Partial land equivalent ratio of yield (pLERY), actual yield loss index (AYL), contribution rate of soil capacity and fertilizer (SCR, SFCR) over time, as well as the differences in coefficient of variation (CV) and sustainable yield index (SYI) at four P application rates (0 kg P ha-1, P0; 60 kg P ha-1, P1; 90 kg P ha-1, P2; and 120 kg P ha-1, P3) based on the two-factor split block design. The linear-platform model was used to simulate the relationship between the grain yield, SYI and the amount of P fertilizer under different P application rates. Results The maize yield in intercropping was significantly superior to the corresponding maize monoculture throughout the six-year experiments. For all planting years, the yield and biomass of the intercropping was higher than that of the matched monoculture average by 56.0% and 56.1%, respectively. And intercropping had an advantage of pLERY and AYL for maize. Otherwise, intercropping reduced the CV by 30.8% and 39.1%, and increased the SYI by 39.4% and 23.0% in P0 and P3 compared with matched monoculture, respectively. For all planting years, the average SFCR in intercropping treatment was higher than that in monoculture treatment. Linear-plateau model fitted showed that intercropping increased yield and SYI by 19.8% and 40.7% on platform, and reduced P application rate by 37.8% and 11.9% at inflection point, respectively. Conclusions These results demonstrate that maize and soybean intercropping could achieve higher yield, higher yield stability and SYI with lower P input than monoculture. Maize and soybean intercropping could be a sustainable practice for promoting the maize productivity and the yield sustainability in red soil of southwest China.
