“…In our study area, the amount of N in AF (CT) soil tended to be lower than that in NS soil. N fertilization is useful for increasing biomass in AF when the amount of soil N is low (Li et al, 2011; Ronnenberg et al, 2011; Ronnenberg & Wesche, 2011; Yu et al, 2015). Therefore, the addition of N to AF is considered an effective way to increase cover.…”

“…Fertilization is effective in increasing the aboveground biomass of perennial plants in Mongolian pastures (Wesche & Ronnenberg, 2010). Further, N fertilization led to an increase in the proportion of perennial grasses in plant communities in Inner Mongolia, China (Bai et al, 2020; Yu et al, 2015). Patterns in N and P are related to variations in species composition (Gong et al, 2011).…”

We investigated the changes in vegetation responses following fertilization in abandoned farmland in Mongolia. Nitrogen (N), phosphorus (P) and potassium were sprayed alone or in combination on abandoned farmland on a typical steppe in Mongolia, and changes in soil nutrients, species composition and vegetation cover were investigated. Abandoned farmland had lower vegetation cover and soil N and P levels than natural grassland. Phosphorus fertilization significantly affected soil phosphate levels. Nitrogen fertilization in abandoned farmland effectively increased vegetation cover. Moreover, combined N and P fertilization increased plant cover over

“…Nutrient addition can impact the structure and variety of grassland plant communities and this can affect grassland productivity. Studies on grassland plant community composition, structure, and variety in response to nutrient addition have crucial theoretical and practical value for the scientific management of grassland, the protection of plant diversity, and the recovery of damaged grassland ( Yu et al., 2015 ; Li et al, 2018 ). Nitrogen (N) and phosphorus (P) are the two most limiting elements affecting grassland productivity and N is generally considered to be the predominant limiting nutrient ( Ma et al., 2008 ; Robertson and Vitousek, 2009 ).…”

IntroductionTajikistan is a typical mountainous country covered by different mountain grasslands that are important pasture resources. Recently, grassland degradation has become widespread due to climate change and human activities and fertilization has been used to improve grassland production. However, fertilizer inputs can substantially alter species diversity, but it is uncl\ear how productivity and species diversity respond to nutrient enrichment in the mountain meadows of Tajikistan.MethodsTherefore, a 5-year (2018–2022) continuous in-situ mineral fertilizer experiment was conducted to examine the effects of three nitrogen (N) levels (0, 30, and 90 kg N ha–1 year–1), two phosphorus (P) levels (0 and 30 kg P ha–1 year–1), and their combinations on above-ground biomass (AGB) and species diversity in a mountain meadow grassland in Ziddi, Varzob region, Tajikistan. Five species diversity metrics—Margalef’s species richness (Dma), the Shannon–Wiener index (H), the Simpson index (C), Pielou’s equitability index (Epi), and the Evar Species Evenness index (Evar)—were used to measure species diversity.Results and discussionsThe results indicated that the addition of different N and P amounts and their various combinations considerably increased both total and dominant species AGB, with the highest increase occurring in the N90P30 (90 kg N ha–1 year–1 combined with 30 kg P ha–1 year–1) treatment in 2022; during the experiment, the importance value of Prangos pabularia (dominant species) first decreased and then increased, but its dominant status did not change or fluctuate among the years. Furthermore, N, P, and their different combinations had no significant effect on species diversity (Dma, H, C, Epi, and Evar). All the species diversity indexes fluctuated among years, but there was no interaction with mineral fertilizer addition. Total AGB had a negative relationship with species diversity and low concentration N fertilizer addition (N30; P30) strengthened this negative trend. However, this trend decreased under the high N fertilizer condition (N90P30). Overall, nutrient addition to the natural mountain grassland of the Varzob region improved AGB, which meant that there was more forage for local animals. Mineral fertilizers had no significant effect on species diversity, but may enhance P. pabularia dominance in the future, which will help maintain the stability of the plant community and improve the quality of the forage because P. pabularia is an excellent and important winter fodder. Our study suggests that scientific nutrient management could effectively promote grassland production, conserve plant variety, and regenerate degraded grassland, which will counteract the desertification process in northwest Tajikistan mountain meadows.
