Soil microorganisms affect both the formation and decomposition of soil organic carbon (SOC). We investigated how nitrogen (N, 25 vs. 100 kg N ha⁻¹) and phosphorus (P, 10 vs. 40 kg P ha⁻¹) fertilisation influenced microbial C use efficiency (CUE) and turnover rate in soil planted with two wheat genotypes, and to what degree these parameters were as...

Rhizodeposition plays an important role in below‐ground carbon (C) cycling. However, quantification of rhizodeposition in intact plant–soil systems has remained elusive due to methodological issues. We used a ¹³C‐CO2 pulse‐labelling method to quantify the contribution of rhizodeposition to below‐ground respiration. Intact plant–soil cores were take...

Plants spend a high proportion of their photosynthetically fixed carbon (C) belowground to support mycorrhizal associations in return for nutrients, but this C expenditure may decrease with increased soil nutrient availability. In this study, we assessed how the effects of nitrogen (N) fertiliser on specific root respiration (SRR) varied among myco...

Plain Language Summary Interactions between nitrogen (N) and phosphorus (P) are important for plant growth and carbon (C) sequestration. While effects of N supply on P dynamics have been much studied, much less is known about the opposite (P‐effect on N). We conducted a meta‐analysis by compiling a total of 1,734 individual experimental observation...

Grassland plants allocate photosynthetically fixed carbon (C) belowground to root biomass and rhizodeposition, but also to support arbuscular mycorrhizal fungi (AMF). These C allocation pathways could increase nutrient scavenging, but also mining of nutrients through enhanced organic matter decomposition. While important for grassland ecosystem fun...

Background and aims Rhizodeposition is organic matter released by living plant roots that can be transformed by microbes into particulate organic matter (POM), but that can also become more stable through the adsorption of organic matter onto soil minerals (mineral-associated organic matter, MAOM), thereby playing an important role in mitigating cl...

Aims Mycorrhiza and rhizodeposition are important for nutrient and water uptake but their role under variable water conditions remains unclear. We investigated how mycorrhiza and rhizodeposition contributed to plant uptake of water, nitrogen (N) and phosphorus (P) in response to water availability and variability. Methods Two tomato genotypes (a m...

Grasslands extend across a variety of topographies including non-flat hilly areas with varied soil texture and moisture that can mediate soil biogeochemical cycling of carbon (C), nitrogen (N) and phosphorus (P). In this study we examined soil organic C, total N and P pools (both inorganic and organic), as well as gross N mineralisation (GNM, as a...

Soil nitrogen (N) availability is determined by microbial gross N mineralisation (GNM) and immobilisation, where net N mineralisation (NNM) represents their balance. Plants provide a substantial amount of their photosynthesized C belowground into the soil as rhizodeposition, which can stimulate microbial activity affecting GNM and NNM, but this act...

Soil nitrogen (N) mineralisation is the conversion of organic into inorganic N by microbes, where net N mineralisation (NNM) represents the balance between gross N mineralisation (GNM) and microbial N immobilisation. Plants provide a substantial amount of their photosynthesised C belowground into the soil as rhizodeposition, which can stimulate mic...

Nutrient loss is one of the most important problems in saffron cultivation which affects saffron production. Summer irrigation during flower initiation period improves saffron yield but affects nutrient availability. This study aimed to evaluate the role of summer irrigation on saffron nitrogen (N) uptake and utilisation efficiency for different or...

Plants allocate their photosynthetic carbon (C) belowground through rhizodeposition, which can be incorporated into microbial biomass and organic matter, but can also be directly shared with arbuscular mycorrhizal fungi (AMF). In this study, we investigated how both rhizodeposition and AMF colonisation are affected by nitrogen (N) and phosphorus (P...

New approaches are needed to counter conventional agricultural management practices that have resulted in significant soil carbon (C) loss. One potential approach is by growing crops that support greater colonization of arbuscular mycorrhizae fungi (AMF). AMF are an important source of soil carbon, and these symbionts provide plants with phosphorus...

Due to climate change it seems that the suitable area for production of saffron is shifting towards the Northern area of Khorasan. On the other hand, corm density and nutrient management are important factors in saffron production. To find out the credibility of this assumption, an experiment was conducted based on a randomized complete blocks desi...

Saffron is mainly produced in southern parts of Khorasan in Iran based on the proper temperature profile available for production that is warm summer and mild fall. The production is used to be intended from Torbate heydariah to Birjand, further south of the province. Due to climate change this trend seems to be reversing and the area of production...

Saffron is a plant specific to warm summer and mild temperature during flowering emergence in the fall. This has been the reason for southern Khorasan to be the most suitable area for saffron production. However, during the recent years due to climate change the temperature profile has changed and the suitable area for production of saffron seems t...

Yield and yield components of sweet corn and eggplant under different proportions of replacement intercropping, examined in randomized complete blocks design with 5 treatments and 3 replications in 2014. The treatments were included 75% sweet corn: 25% eggplant, 50% sweet corn: 50% eggplant, 25% sweet corn: 75% eggplant and sole cropping of each pl...

Intercropping is one of the environmental friendly ways to improve the use of resources and weed control. A field experiment was performed on maize intercropped with sweet basil and borage under weed free and infestation conditions. The experimental design was a factorial based on randomized complete block design with three replicates. Factors incl...

In order to evaluate intercropping of soybean (Glycine max L. cv. JK) with sweet basil (Ocimum basilicum L.) and borage (Borago officinalis L.) with weed interference, an experiment was performed in randomized complete block design with 12 treatments and three replications at a field located 10 km of Shirvan during year of 2011. The treatments were...

Several specimens belonging to the genus Pseudocercospora were collected from different localities of Mazandaran province (N Iran) during the 2011–12. All specimens were microscopically studied and identified. As the result Pseudocercospora abeliae (on Abelia grandiflora), P. rhamnaceicola (on Paliurus spina-christi) and P. sordida (on Campsis gran...

In order to identify Passalora and Ramularia species, Leaf spot symptoms from different plant hosts in Mazandaran province were collected and examined during the spring-autumn 2011-12. Passalora brandenburgeri (on Salix alba) and Ramularia variabilis (on Verbascum blattaria) are reported as the new records for Iran. Furthermore, Rosa hybrida and Ru...

Cercosporoid fungi including the genus Cercospora and other morphologically similar genera are important pathogens causing leaf spots on a wide range of host plants. In a taxonomic study on cercosporoid fungi, plants with leaf spot symptoms from different localities of Mazandaran province were collected and examined during spring-autumn 2011-12. As...

Intercropping is one of the sustainable agricultural factors. The SPAD meter can be used to predict nitrogen index reliably, it may also be a useful tool for assessing the relative impact of weeds on crops. In order to study the effect of weeds on SPAD in corn (Zea mays L.), sweet basil (Ocimum basilicum L.) and borage (Borago officinalis L.) in in...

Use of the growth indices is a method to assessment of intercropping efficiency. In order to evaluation growth indices of soybean, sweet basil and borage in intercropping with different ratios, an experiment base on randomized complete block design was conducted with 9 treatments and 3 replications at north Khorasan in 2011. Treatments were consist...
