In terms of providing additional feeds and improving the soil fertility, planting forage crops during fallow seasons is an effective strategy to promote resource utilization. The objective this research was compare effects different on yields nutritive compositions properties winter paddy in southern China. Five crops, including alfalfa ( Medicago sativa , AF), common vetch Vicia CV), milk Astragalus sinicus MV), smooth villosa SV) Italian ryegrass Lolium multiflorum IR), were planted by monoculture 2017-2018 (season 1) 2018-2019 2), respectively. dry matter yield IR significantly higher than those AF, CV, SV MV P <0.05). crude protein CV neutral detergent fiber acid contents lower AF Forage affected culturable microbial population soils bacteria, actinomyces fungi numbers highest, while azotobacter number lowest. catalase, acid-phosphatase invertase activities highest. best obtain improve soil. When producers pursue yield, we recommend ryegrass. If want characteristics, most suitable plant. These results provide useful information rice growers for cropping management when growing (based nutritional value) or green manure fertility) as alternative late harvest.

Reasonable deep application of sheep manure fertilizer to alleviate soil acidification to improve tea yield and quality

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: June 23, 2023

Soil acidification in Chinese tea plantations is widespread, and it has significantly affected the growth of trees; was important to explore soil remediation acidified depth for sustainable development industry. In this study, effects sheep manure fertilizer with different application depths on acidification, yield quality, nitrogen transformation were analyzed five consecutive years from 2018 2022. The results showed that long-term use reduced ( P < 0.05) plantations, improved pH ammonium content, enhanced root activity uptake capacity trees, thus quality. effect quality mainly reflected ability nitrate nitrogen, which high content beneficial vice versa, best achieved when applied at a 50 cm 70 cm. topsis analysis confirmed fertilization had greater activity, ammonia intensity, nifH gene. This study provided an practical basis restoration plantation through management.

Legume-potato rotation affects soil physicochemical properties, enzyme activity, and rhizosphere metabolism in continuous potato cropping

Chemical and Biological Technologies in Agriculture, Journal Year: 2023, Volume and Issue: 10(1)

Published: Nov. 22, 2023

Abstract Background Continuous cropping can reduce soil quality and affect rhizosphere metabolism, ultimately reducing crop yield. Crop rotation mitigate the damage caused by continuous cropping, but different patterns respond differently to metabolism. We investigated effects of on physicochemical properties, enzyme activities, microbial quantity, metabolism potato based a long-term field study from 2018 2022. The experiment was set up with following three treatments: ( Solanum tuberosum L.)-potato-potato-potato-potato (CK), potato-potato-potato-pea Pisum arvense L.)-potato (T1), potato-potato-potato-faba bean Vicia faba (T2). Results results showed that pea-potato (T1) bean-potato (T2) significantly improved properties enhanced activity, increased yield 21.19% 28.38%, respectively, compared crop. Non-targeted metabolomics analysis differential metabolites were mainly nucleotides, organic acids derivatives, flavonoids cropping. These are enriched in ABC transporter, purine pyrimidine phenylalanine pathways. Combined analyses legume-potato rotations quantity increasing tuber yields. In addition, correlation l -Tyrosine, Trans-Cinnamic acid, Guanine, Adenine) also strongly associated these measurements. Conclusions Therefore, we conclude modulate abundance function alter low molecular metabolite profile under conditions. Some important may play part cycling nutrients soil, making its better, raising activity enzymes, tubers. above indicate has positive effect soils. It lays solid foundation for revealing complex network metabolic pathways communities after legume rotation. Graphical

Soybean continuous cropping could alter soil microbial communities, leading to the development of continuous-cropping obstacles that negatively impacted yield. Different soybean cultivars exhibited varying degrees resistance these obstacles. However, mechanisms underlying this remain unclear. In study, microbiology and metabolomics were employed explore impacts on rhizosphere communities metabolite profiles two cultivars. The results indicated did not reshape bacterial fungal community diversity but reshaped their structures. potentially pathogenic fungi continuous-cropping-sensitive cultivar (ACR) higher than those continuous-cropping-tolerant (LCR), which suggested disease might be a crucial factor in mitigating barriers. metabolomic showed metabolic significantly different, some metabolites, promote growth pathogens, ACR LCR.
