“…They found that wheat and rapeseed straw mulch increased total NPK accumulation in rice plants by 1.81-10.79%, 2.70-42.21% and 16.41-17.92%, respectively, consequently enhancing NPK utilization. Nonetheless, innovative ideas for nutrient recovery are considered for paradigm of the biorefineries, where the wastes from the one system must be entirely reinstated in the market as raw material [126].…”

Agricultural sector has inescapably drawn attention towards itself due to growing concern over population explosion, changing climate and depletion of resources. Advancements in technology have caused rapid boost in farm productivity and hence huge production of agro-wastes. There have been massive deteriorating impacts of agro-wastes on existing environmental conditions, creating wide scale environmental pollution as well as biodiversity loss. Since, agro-wastes have huge potential in the form of energy and nutrient recovery (ENR), amalgamations of different technologies would promote sustainability. ENR not only adjoins an added profitable product but also facilitates to close environmental nutrient cycles. This provides a substitute to existing unsustainable approaches that are energy demanding and reliant on nonrenewable sources of energy. This review underpins why ENR from agro-waste must be key concern in production of array of higher value products.

“…Previous studies have reported that wheat and maize residues associate with low N mineralization, because N immobilization from the soil negatively influences the amount of available N in plants [13][14][15][16]. On the other hand, due to advancements in agricultural mechanization, the slow decomposition rate of large amounts of straw (the annual decomposition of straw plowed into the field is about 60%) results in the accumulation of straw [17,18], which is not conducive to planting and growth. Therefore, it is imperative to accelerate the maturation of straw and reduce the inhibition of early rice growth by straw return.…”

This study aimed to improve nitrogen utilization and alleviate the inhibition of straw decomposition during early tillering and the growth of paddy after straw return. Specifically, three different nitrogen fertilizer (base fertilizer) application methods were tested under full straw return: applying the compound fertilizer once (J1), applying the compound fertilizer twice (J3) and applying the ammonium carbonate fertilizer plus compound fertilizer (J2). Full straw return without fertilizer (CK1) and no straw return without fertilizer (CK2) were used as the controls. The results showed that treatment with ammonium carbonate fertilizer combined with compound fertilizer (J2) significantly enhanced straw decomposition, light interception and dry matter accumulation at an early stage of tillering, but reduced tiller occurrence at a late tillering stage. Grain yield was affected due to reduced dry matter accumulation, nitrogen use efficiency and number of effective panicles. There were no significant differences in rice growth, nitrogen use efficiency and grain yield between the one-time or two-time compound fertilizer application methods. In contrast, treatment with ammonium carbonate fertilizer combined with compound fertilizer (J2) under full straw return effectively improved straw decomposition and accelerated the return of green and tillering. In addition, the proportion of ammonium carbonate fertilizer affected the nutrient utilization efficiency and yield at later stages.

“…The increase of large pores in the vertical direction in no-till soil could enhance water permeability in the soil profile. Under the conditions of no-till management with straw mulching, the rice root system development was better, which improved the utilization of rice field water and soil nutrients, making it easier for grains to obtain nutrients, thereby increasing yield [45][46][47]. However, the effect of no-till management on N and P accumulation in grain and straw was small, which could have possibly occurred because no-till and straw mulching reduced the soil nutrient output in most non-irrigated areas.…”

“…The annual environmental losses during the planting season for 2 consecutive years were less than those during the rice season, mainly because of the effects of fertilization during the rice season and the return of straw to the field during the fallow season. Although rice straw residues contained some N and P, other researchers have pointed out that it takes time for straw mulching to release nutrients into the soil [47]. Therefore, there were lower environmental losses during the planting season because the soil during the rice season could acquire more nutrients through fertilization and straw mulching [48].…”

Background: Nutrient balance in rice paddy fields can change under different tillage management practices; however, the extent of the change may differ for various rice varieties. A field experiment was conducted over 2 successive years to clarify the effects of no-till and rice varieties on the apparent balance of nitrogen (N) and phosphorus (P). Four treatments: no-till/japonica rice (NTJ), no-till/glutinous rice (NTG), conventional tillage/japonica rice (CTJ), and conventional tillage/glutinous rice (CTG) with three replicates of each were established to test the hypothesis that no-till and japonica rice can improve the apparent balance of nutrients. Results: The tillage method and rice variety had interactive effects on the apparent balance of N and P. After the 2-year experiment, total N and P pools in the 20 cm surface soil layer were highest under the NTJ treatment (4757.0 kg N ha −1 , 2428.5 kg P ha −1) and lowest under the CTG treatments (4726.3 kg N ha −1 , 2412.0 kg P ha −1). Under no-till conditions, japonica rice had higher grain yield but lower straw biomass than that of glutinous rice. NTG treatment significantly increased the N and P content in rice grains and straw. The environmental losses of N and P in the rice fields mainly occurred during the rice season. Based on nutrient balance estimation, N losses in the NTJ, NTG, and CTJ treatments were reduced by 15.03 kg N ha −1 , 11.55 kg N ha −1 , 6.72 kg N ha −1 , respectively, as compared with that of the CTG treatment. The corresponding P losses were reduced by 8.02 kg P ha −1 , 7.84 kg P ha −1 , and 3.96 kg P ha −1. In terms of economic benefits, NTJ also resulted in the highest actual income (2724.25 US dollars) and the highest ratio of production investment (6.40). Conclusion: No-till was more likely to maintain soil N and P nutrients than conventional tillage, and this advantage was most significant when planting japonica rice. In addition, no-till was conducive to N and P uptake by rice, but only japonica rice exhibited increased grain yield. Consequently, the NTJ treatment was recommended to improve the N and P balance.
