1. IntroductionCh.na is entering an impressive era of grain production since its reform and opening up in 1978. At present, Ch.na feeds 22% of th. world population with.only 9% of th. world＇s arable land [1]. Th.s, Ch.na h.s become a leader in th. global figh. against h.nger[2] . Grain production h.s increased dramatically, from about 3 × 10^8t in 1978 to 6.21 × 10^8t in 2016, wh.ch.is an annual increase rate of 9% [3].

Plastic film mulch.systems are used widely in arid areas, and th. associated tillage measures affect soil properties, root and crop growth. and nutrient uptake. h.wever, much.debate surrounds th. most suitable tillage meth.d for plastic film mulch.systems. We conducted a two-year field experiment to explore th. impact of th.ee tillage treatments-rotary tillage before ridge–furrow plastic film mulch.mR), no-tillage before ridge–furrow plastic film mulch.mZ), and plow tillage before ridge–furrow plastic film mulch.mP)-on soil total nitrogen, available nitrogen, root stratification structure,nitrogen transfer and utilization, and maize yield. Th. results sh.wed th.t mP h.d better soil quality th.n eith.r mR or mZ over 2019 and 2020, with.h.gh.r nitrate-nitrogen and total nitrogen in th. 0–40 cm soil layer. mP improved th. soil ph.sicoch.mical properties more th.n th. oth.r treatments, producing significantly h.gh.r root numbers and root biomass for th. aerial and underground nodal roots th.n mR and mZ. At h.rvest, mP h.d th. h.gh.st root biomass density,root length.density, and root surface area density in th. different soil layers(0–20, 20–40, and 0–40 cm). Significant correlations occurred between root biomass and aboveground nitrogen accumulation during maize growth. During grain filling, mP h.d th. greatest nitrogen transfer amount, significantly increasing root and aboveground nitrogen transfer by 19.63–45.82% and 11.15–24.56%, respectively, relative to th. oth.r treatments. mP significantly produced 1.36–26.73%h.gh.r grain yields and a h.gh.r grain crude protein content at h.rvest th.n mR and mZ. mP also h.d h.gh.r values for th. nitrogen h.rvest index, nitrogen uptake efficiency, and partial factor productivity of nitrogen fertilizer th.n mR and *** conclusion, plow tillage combined with.a ridge–furrow plastic film mulch.system facilitated maize root development and improved nitrogen utilization, th.reby increasing maize yield more th.n th. oth.r treatments.

Soil total nitrogen is critical for crop productivity and related to agricultural managements. h.wever, th. effects of different fertilizer applications on soil total nitrogen storage are not well understood. To quantify soil total nitrogen storage under different fertilizer management practices and explore th. effects of climate, soil texture, experimental duration, and cropping system on soil total nitrogen storage in Ch.na, we conducted a meta-analysis of 67 fertilizer management strategies from experiments conducted over a period of at least th.ee years. Th.s meta-analysis included 854 observations of ch.nges in soil total nitrogen stock(TNS) under no fertilizer application(control, CK), ch.mical fertilization with.nitrogen, ph.sph.rus, and potassium(CF), CF plus straw retention(CFS), and CF plus manure addition(CFm) relative to initial soil TNS. Th. CFm and CFS treatments increased soil TNS, and th. CFm treatments increased soil C/N ratio th. most. Th. longer th. experimental duration, th. greater th. increase in soil TNS in th. CF, CFS, and CFm *** texture and crop type significantly affected th. ch.nges in soil TNS. Th. experimental duration, initial soil TNS, soil C/N ratio, and cropping system h.d significant linear correlations with.th. ch.nge in soil TNS. Temperature and precipitation were not correlated with.soil TNS. Results of random forest modeling indicated th.t th. most important factor affecting ch.nges in soil TNS was experimental duration(positive correlation), followed by initial soil TNS(negative correlation). Th. CFm treatments h.d th. largest increase in soil TNS under various conditions. We recommend promoting CFm to improve soil fertility in farmlands globally.
