“…Furthermore, we noticed that the MNPK compared with M and NPK enhanced the wheat grain yield by 55.67% and 24.14%, maize grain yield by 76.65% and 33.63%, and soybean grain yield by 23.42% and 18.79%, respectively (Figure 2a). Earlier studies also supported our results and reported that mixed application of manure and mineral fertilization increased grain yields compared with mineral only treatments and implied this yield increment to better nutrient uptake (Gai et al, 2018;Waqas, Li, Smith, et al, 2020;Wei et al, 2016).…”

“…The positive role of manure application alone and in combination with mineral fertilizers in improving soil health dynamics and crop productivity has been described in the past on both regional and national croplands. For example, in Chinese croplands, the average SOC sequestration of 0.43 Mg C ha −1 per year can be achieved through the integrated use of manure and mineral fertilizers, and each increase of 1 Mg C ha −1 leads to an increase in grain yields of rice, wheat, and maize by 143, 255, and 202 kg ha −1 , respectively (Waqas, Li, Smith, et al, 2020). Likewise in a long‐term study, Kätterer et al (2011) observed an incremental trend in SOC stock with the application of manure while Zhengchao et al (2013) found that long‐term manure fertilization may result in no change or even a net loss of C and N stocks.…”

Subsoils contain half of the total soil organic carbon (SOC) that is supposed to be relatively more persistent than that present in the topsoil. Improving SOC and total nitrogen (TN) stocks in croplands is crucial to mitigate climate change and ensuring food security. However, our insight into how the management practices and climatic variables influence stocks of SOC and TN, and crop grain yields in the soil profile is limited. In this study, we assessed the long-term impacts of mineral and manure fertilizers on SOC and TN stocks at soil profile levels (up to 100 cm), and cropping system (wheat-maize-soybean) grain yields. Results indicated that in the top 0-40-cm layers SOC and TN stocks were the highest in manure plus mineral fertilizers (MNPK) compared with control, that is, non-fertilized control (CK). Conversely, compared with NPK, sole application of manure (M) clearly increased SOC stocks by 19%, 40%, and 39% and TN stocks by 51%, 105%, and 116% in 40-60, 60-80, and 80-100 cm, respectively (p < 0.05). Moreover, Pearson correlation revealed that climate variables, that is, mean annual temperature (MAT) affected both SOC and TN stocks in 0-40-cm layers only of the soil profile. Our findings implicated that the sole application of manure (M) is vital to augment SOC and TN sequestration, particularly in the subsurface layers. However, trade-offs between SOC and TN sequestration and crop yields should also need to be considered while making recommendations for

“…Numerous studies have shown that crop yields increase with increased fertilization [19,36,37]. Our results likewise showed that bamboo-shoot yield increased with increasing fertilizer application (Figure 1), which was due to the increases in soil nutrients (Olsen P, AN, SOM, and AK) contents via applying NPK inorganic compound fertilizers (Tables A1 and A2).…”

Stand-density management and fertilization practices are the main two factors affecting bamboo-shoot yield. However, the appropriate density and fertilization rates are still unclear for improving the bamboo-shoot yield and its economic benefits, especially for a high economic value bamboo-shoot forest. To fill this gap, we conducted a two-year split-plot design experiment in a Chimonobambusa pachystachys shoot forest. The main plots were assigned to five density rates, 40,000, 50,000, 60,000, 70,000, and 100,000 culms ha−1, and the subplots were assigned to four fertilization rates (nitrogen:phosphorus:potassium = 23:3:15): 0, 820, 1640, and 2460 kg ha−1 a−1. Results showed that the bamboo-shoot yield increased first and then decreased with stand density, while it increased with fertilization rates. Density management and fertilization regulate bamboo-shoot yield by changing the soil’s Olsen P, available nitrogen, organic matter, and available potassium contents. The maximum bamboo-shoot yield was 9315.92 kg ha−1, which appeared in the density of 60,000 culms ha−1 and the fertilization of 2460 kg ha−1 a−1. However, the maximum bamboo-shoot net profit was 135,242.63 CNY ha−1, which appeared at the density of 60,000 culms ha−1 and the fertilization of 1640 kg ha−1 a−1. The economic-benefit analysis shows that density management achieves a net-profit growth comparable to fertilizer application at a much lower cost. The study results provide a basis for the scientific management of C. pachystachys shoot forests and bamboo farmers to improve their income.

“…Over the past few decades, intensive farming practices, e.g., excessive inorganic fertilization and tillage, have been widely adopted to enhance crop productivity to meet the increasing domestic food demand in China. These practices degrade soil quality, meaning more unfavorable soil conditions for crops to grow (Droste et al, 2020;Waqas et al, 2020). Degraded soil quality will also make a cropping system more vulnerable to warming according to our results.…”

The impacts of global climate warming on maize yield vary regionally. However, less is known about how soil modulates regionally specific impacts and soil properties that are able to alleviate adverse impacts of climate warming on maize productivity. In this study, we investigated the impacts of multiple soil inherent properties on the sensitivity of maize yield (SY,T) to growing season temperature across China. Our results show that a 1°C warming resulted in the largest yield decline (11.2 ± 6.1%) in the mid-eastern region, but the moderate yield increase (1.5 ± 2.9%) in the north-eastern region. Spatial variability in soil properties explained around 72% of the variation in SY,T. Soil organic carbon (SOC) content positively contributed the greatest extent (28.9%) to spatial variation of SY,T, followed by field capacity (9.7%). Beneficial impacts of increasing SOC content were pronounced in the north-eastern region where SOC content (11.9 ± 4.3 g kg−1) was much higher than other regions. Other soil properties (e.g., plant wilting point, sand content, bulk density, and saturated water content) were generally negatively correlated with SY,T. This study is the first one to answer how soil inherent properties can modulate the negative impacts of climate warming on maize yield in China. Our findings highlight the importance of SOC in alleviating adverse global warming impacts on maize productivity. To ensure food security for a rapidly increasing population under a changing climate, appropriate farming management practices that improve SOC content could reduce risk of adverse effects of global climate warming through a gain in yield stability and more resilient production in China’s maize belt.
