“…Such shifts in fungal community composition could affect the soil enzymatic activities and litter decomposition and, thus, modulate soil C, N, and P cycling in forests exposed to atmospheric N deposition ( Ning et al, 2018 ). Recent studies demonstrated that soil pH and NO 3 – –N concentration were the key drivers influencing fungal community composition ( Francioli et al, 2016 ; Ullah et al, 2019 ; Wang et al, 2021 ). The relative abundance of dominant functional guilds, phyla, and genera ( Supplementary Figures 5 , 6 ) was significantly positively or negatively correlated with soil pH and NO 3 – –N concentration at the short-term site, depending on their preference to N and tolerance to pH, which also proved the soil fungal community to be sensitive to short-term N addition.…”

Soil fungi play critical roles in ecosystem processes and are sensitive to global changes. Elevated atmospheric nitrogen (N) deposition has been well documented to impact on fungal diversity and community composition, but how the fungal community assembly responds to the duration effects of experimental N addition remains poorly understood. Here, we aimed to investigate the soil fungal community variations and assembly processes under short- (2 years) versus long-term (13 years) exogenous N addition (∼100 kg N ha–1 yr–1) in a N-rich tropical forest of China. We observed that short-term N addition significantly increased fungal taxonomic and phylogenetic α-diversity and shifted fungal community composition with significant increases in the relative abundance of Ascomycota and decreases in that of Basidiomycota. Short-term N addition also significantly increased the relative abundance of saprotrophic fungi and decreased that of ectomycorrhizal fungi. However, unremarkable effects on these indices were found under long-term N addition. The variations of fungal α-diversity, community composition, and the relative abundance of major phyla, genera, and functional guilds were mainly correlated with soil pH and NO3––N concentration, and these correlations were much stronger under short-term than long-term N addition. The results of null, neutral community models and the normalized stochasticity ratio (NST) index consistently revealed that stochastic processes played predominant roles in the assembly of soil fungal community in the tropical forest, and the relative contribution of stochastic processes was significantly increased by short-term N addition. These findings highlighted that the responses of fungal community to N addition were duration-dependent, i.e., fungal community structure and assembly would be sensitive to short-term N addition but become adaptive to long-term N enrichment.

“…In our study, there were 16 treatments with different temperatures and we measured the germination percentage. In previous, research scientists reported germination percentage of jojoba and other oil seeded crops readily growing fast in sandy, clay soil, and against different temperature ranges (Gentry, 1958;Domènech and Vilà, 2008;Ullah et al, 2019). The results given in Table 1 (Miwa, 1984).…”

J ojoba is an economical desert plant, which can be grown successfully in arid and semi-arid deserts. It is a dioeciously, perennial, evergreen, woody shrub scientifically known as Simmondsia chinensis. Jojoba is considering very precious plant that can survive under drought, saline water, extreme hot climatic conditions and resists pest attack. An interesting fact about the jojoba plant is that nature has covered its leaves with a waxy coating/sheet, which helps to reduce the evapotranspiration from its leaves thus reducing the loss of moisture at a very minimum level. This probably is one of the most important reasons for its survival under desert conditions. Jojoba seed used in cosmetic industries because it contains 40 to 50% oil which 'is useful for lotions, massage oils, lipsticks, smoothing creams and nail polishes. It, s also has potential for lubricant, printing and pharmaceutical industries (Benzioni et al., 1999). The oil extracted from Jojoba is usually called as "Liquid Gold". The chemical composition of jojoba oil resembles that of whale fish oil. As a strict ban is being observed on the hunting of whale fish at the international level, Abstract | Among arid zone plant species, Jojoba (Simmondsia chinensis), being an evergreen, perennial, multi-stemmed, and multipurpose plant has attracted wide attention due to its economic value, potential byproducts and ability to withstand vagaries of the desert environment. By realizing the economic importance of this high-value desert plant, a pioneer study on seed germination response to various agro-climatic factors was conducted at the Arid Zone Research Institute Bahawalpur. Healthy jojoba seeds were sown at the fortnightly intervals by dividing the whole year into 16 treatments to identify the optimum sowing time for the Cholistan desert of Bahawalpur. The results revealed that maximum germination rate of 85.63%, 85.93%, and 82.83% were found in treatment 16 th September during the whole study period (2011-14). The 16 th of March, 16 th September, and 1 st August were the other suitable sowing times for jojoba as these showed 82.37%, 75.47%, and 71.57% of germination respectively.

“…The high frequency of Humicola fuscoatra (69%) under Crotalaria + N could be in response to the availability of a high available N and simple sugars released from residual abundant dead roots (previous maize crop and dry season weeds), the little SOM and the current resource applied [ 5 , 25 ]. The reduction in Exophiala sp SST 2011 and Cladosporium perangustum frequencies indicates the detrimental effect of available N and influx of simple sugars (deprived of cellulose and lignin), under Crotalaria + N. The direct detrimental effect of ammonium nitrate was confirmed by the vanishing of different species and reduction of community diversity across treatments and over time [ 42 , 56 , 57 ].…”

Recent advocacy for Integrated Soil Fertility Management (ISFM) in smallholder farming systems in east and southern Africa show substantial evidence of increased and sustained crop yields associated with enhanced soil productivity. However, the impact ISFM on soil fungi has received limited attention, yet fungi play key roles in crop growth. Following total soil DNA extraction with ZR soil microbe miniprep kit, illumina sequencing was used to, examine the fungal communities (ITS1F) under a maize crop following co-application of organic nutrient resources including Crotalaria juncea, cattle manure and maize stover with inorganic fertilizers at three-time periods (T1-December, T2-January, and T3-February) in Zimbabwe. Ninety-five fungal species were identified that were assigned to Ascomycota (>90%), Basidiomycota (7%) and Zygomycota (1%). At T1, Ascomycota and Basidiomycota were identified across treatments, with Ascomycota attaining > 93% frequency. Fungal succession was noted and involved reduction of Ascomycota coupled by increase in Basidiomycota under the different treatments. For example at T3, Basidiomycota increased to 34% while Ascomycota declined to 66% under manure but remained unchanged in other two organics. Pre-season mineral nitrogen (N) associated with the ‘Birch effect’ apparently influenced the fungal community structure at T1 while readily available fertilizer N was critical at T2 and T3. The low-quality maize stover promoted the presence of Exophiala sp SST 2011 and this was linked to N immobilization. The impact of N addition was more pronounced under medium (manure) to low-quality (maize stover) resources. Fungi required phosphorus (P) and N for survival while their proliferation was dependent on substrate availability linked to resource quality. Interactive-forward test indicated that soil available P and N were most influential (P < 0.05) factors shaping fungal communities. Co-application of medium to high quality organic and inorganic resources show promise as a sustainable entry point towards enhancing belowground fungal diversity critical in driving nutrient supply.
