Duckweeds, such as Lemna minor L., are invasive aquatic species that can proliferate on the surface of nutrient solution in hydroponic systems, requiring removal operations from cultivation tanks and disposal waste. Several studies have demonstrated potential use duckweeds an organic fertilizer. Recycling plant waste a source for crops may be circular approach to enhancing sustainability intensive horticultural production systems. Two pot experiments were carried out evaluate possibility using biomass fertilizer lettuce. The following fertilization treatments applied: Control (no fertilization), (60, 120, 180 kg ha−1 nitrogen), urea (60 commercial nitrogen). Lettuce head diameter, fresh dry weight, number leaves, contents minerals, nitrates, chlorophyll carotenoids determined. In addition, nitrogen efficiency was calculated. Fertilization with resulted significant increase yield compared control (+50% considering average three doses) both inorganic (+65%) (+71%) treatments. No differences quality observed between doses Lemna, but lowest one treatment best performance terms N productivity. These results suggest proper nutrients lettuce advantages no effect quality. Therefore, its alternative fertilizers allow farmers profitably exploit product and, at same time, reduce costs fertilization, thus achieving environmental economic benefits.

Abstract Purpose Reductive soil disinfestation (RSD) can remove over-accumulated nitrate (NO3−-N) from topsoil in intensive vegetable fields via elevating NO3−-N consumption processes. The duration of cultivation may affect the relative importance these consuming processes during RSD treatment by altering properties. However, it remains elusive how affects fates treatment. Methods Here, a column experiment labeled with K15NO3 was conducted to investigate effects different ages (5, 10, 20 and 30 years) vegetables on under Results results showed that more than 91.8% added 15NO3−-N removed treatment, regardless years. There trade-off between denitrification leaching into subsoil, both which together accounted for 85.5–97.1% 15NO3−-N, proportion gaseous 15N loss (Pdenitrification) initially increased 5 10 years cultivation, then decreased further ages, but trend reversed subsoil (Pleaching). structural equation model revealed initial carbon/nitrogen ratio had an indirect positive effect Pdenitrification driving nirK abundance Conclusion Overall, our highlight critical role using removing accumulated its Pleaching as cultivation.

Climate change has intensified the increase in irrigated crops to solve frequent droughts, but part of stress continues due heat waves, and for these systems, there is a lack in-depth discussion about their damage strategies minimize this damage. The caused by high temperatures may be exacerbated with nutritional disorder nitrogen, optimized management nutrient can help mitigate effects stress. This merits further debate, as it would sustainable strategy without risk environment at same time could induce greater plant tolerance review will address relevance rising isolated on crop nutrition productivity role nitrogen use mitigating propose future perspectives research that researchers improve thermotolerance. Nitrogen plays an essential metabolism, inducing production proteins from photosynthesis, boosting primary secondary metabolism and, consequently, defense systems plant. Studies indicate adequate supplementation resilience temperatures, improving water efficiency promoting synthesis shock proteins. In addition, new fertilizer management, such nitrification inhibitors biofertilizers, have demonstrated reducing environmental losses, they impact mitigation. Although negative waves plants, are still gaps knowledge underlying biochemical physiological mechanisms involved whether doses N used really optimal maximizing plant’s system against outlook become important not only guarantee yields also wave losses strengthening deal context climate change, better understanding benefits manage towards more agriculture.

Adopting an optimal cropping regime is crucial for sustainable soil use. However, how different regimes impact phosphorus (P) availability and the underlying mechanism remain unclear. Here, a 10-year field experiment was performed to examine influence of regimes, including maize–soybean rotation (MSR), continuous maize (CMC), farmland fallow (FALL), under unfertilized fertilized conditions in Northeast China. The P forms were analyzed using chemical fractionation solution phosphorus-31 nuclear magnetic resonance. Compared FALL, total contents significantly lower MSR CMC systems. Moreover, higher than those CMC. Correlation analysis showed that there significant positive correlations between contents. Redundancy revealed organic carbon (SOC) as most factor influencing P. Structural equation modeling demonstrated direct impacts SOC, nitrogen, phosphorus, Olsen on phosphatase activity, which exhibited availability. In summary, effective promoting accumulation this region.
