“…No artificial irrigation was carried out during the growth of grass, so the yield was mainly affected by climate and farming system. It has been confirmed in similar early rice–late rice–forage crop (Xu et al, 2021) and early rice–late rice–vegetable (Huang et al, 2021) rotation systems. The DM yield of no‐tillage increased slightly compared to CK; the reason was that no‐tillage improved soil moisture and nutrients and promoted the accumulation of photosynthetic product in crops (Jha et al, 2020).…”

It is common in southern China that rice (Oryza sativa L.) fields are sown with a cover crop like Italian ryegrass (Lolium multiflorum L.) following autumn harvest. The objective of the present research was to compare the effects of different no‐tillage methods on the yield, nutritive composition and silage fermentation quality of Italian ryegrass. Italian ryegrass was planted in winter fallow paddy fields on 9 days (NT9) and 5 days (NT5) prior to rice harvest and on 1 day after rice harvest for 2 years. Sowing prior to harvest was no‐tillage, and sowing after rice harvest was either no‐tillage (NT1) or conventional tillage (CK). The grass was harvested and ensiled two times each year. The growing year had no significant effects on the yield and most nutrition components, while it had significant effects on pH value, butyric acid and NH3‐N contents of silage. There were no differences in the yield, nutritional composition and silage fermentation quality among sowing methods. The neutral detergent fiber and acid detergent fiber of NT1 decreased slightly compared with NT9, NT5 and CK (p > .05). There was no difference in silage fermentation quality among the four treatments. The best sowing method for Italian ryegrass with second cut in winter fallow paddy was no‐tillage sowing after rice harvest.

“…On the other hand, many studies have showed that intensified rotation systems improve SOM content through greater carbon input and higher fungal biomass and aggregation (Huang et al, 2021; Mcdaniel et al, 2014; Rosenzweig et al, 2018). Available field experiment results have widely proved that fertiliser application could increase soil carbon and sequester more carbon from the atmosphere (Lu et al, 2009).…”

Soil organic matter (SOM) plays a critical role in terrestrial ecosystem functioning and is closely related to many global issues like soil fertility, soil health and climate regulation. Therefore, obtaining accurate information on the spatial distribution of SOM and its potential controlling factors is of global interest. However, this remains a great challenge since SOM is affected by numerous natural and anthropogenic factors and usually showed strong heterogeneity. In this study, we collected a total of 16,580 surface soil (0–20 cm) samples from the farmland throughout Jiangxi Province. And the Random Forest (RF), Cubist and gradient‐boosted models were compared and used to define the factor which is most associated with SOM. Then the ordinary kriging (OK) and machine learning‐ordinary co‐kriging (ML‐COK) were used to map SOM. We found that on average, 30.86 g kg−1 SOM was present in farmland soil of Jiangxi Province. Anthropogenic activities strongly affected SOM level, with five of the top 10 most important factors are anthropogenic related. The straw return amount was proved to have the largest importance (31.46%) for modelling SOM and a significant (p < 0.001) positive relationship between SOM content and the amount of straw returned to farmland was detected. Additionally, returning straw improved crop production. Soil derived from the Quaternary Subred Sand has the highest SOM content (37.82 g kg−1). Crop rotation also improved SOM content and the rice‐bean rotation system has the highest SOM content (34.27 g kg−1). With the best performance, the RF algorithm (R2 = 0.49, RMSE = 6.77 g kg−1) was selected to identify the primary control of SOM and integrated with COK, which we termed as ML‐COK, to map the SOM in the farmland of Jiangxi Province. ML‐COK outperformed OK method for mapping the SOM in farmland of Jiangxi Province with R2 of 0.351 and Lin's concordance correlation coefficient of 0.549. Farmland distributed in the central part of the province had high SOM content. In contrast, farmland in the north, south and east parts had relatively low SOM. Our study offers new insight for mapping soil properties, identifying potential factors driving variation in SOM, and also provides valuable information for making more reasonable and environmentally friendly farmland management measures.

“…1 ), which is consistent with Singh et al ( 22 ). This might be attributed to the fact that paddy-upland crop rotation systems could improve soil fertility, crop diversity, and crop yields ( 23 ). Moreover, the soil available nutrients, AN, AP, and AK, of treatment D were indeed higher than those of other treatments, indicating that the frequent alternating cycles of anaerobic and aerobic conditions in the paddy-upland rotation system promoted carbon and nitrogen cycles, thereby improving the content of available N, P, and K in the soil ( 24 , 25 ).…”
