Abstract:

Maintaining the levels of nitrogen in agricultural fields to ensure crop yield performance is challenging due to the complex dynamics of nitrogen transformation in soil. Nitrogen is mainly taken up by plant roots in the form of nitrate, but it is considered as an environmental pollutant that threatens human and animal health. Therefore, it is necessary to use adsorbent compounds to retain nitrate in the soil. The effectiveness of two types of biochar produced from rice husk (Br) and populous wood (Bp) and two arbuscular mycorrhizal fungi, namely Funneliformis intraradices (Mi) and Funneliformis versiforme (Mv), on nitrate leaching in soil was evaluated. The soil columns planted with corn were filled with an artificial sandy clay loam soil fertigated with urea fertilizer under glasshouse conditions . After nine weeks of growing the plants, a pulse of nitrogen (0.48 g urea per core) was added to the columns. One week after the addition of urea, the shoots of the plants were removed, and the columns immediately flushed with 500 ml of deionized water to leach the soil nitrogen from the columns. The results showed that the shoots' dry-weight increased significantly (p≤ 0.05) in almost all the treatments with the highest in the BrMi treatment when compared to the control (C). The nitrate concentration in the leachate decreased 79% (from 23.2 mg/l in C treatment to 4.2 mg/l in Bp treatment), but the nitrate concentration in the soil solution increased up to 6.7-fold (Bp was the highest), which suggested a high N retention by the biochars used. It was concluded that the application of biochar and mycorrhizal fungi could reduce nitrogen loss through this artificial sandy clay loam soil and may have some implications in environment conservation.

Plant and soil response to single and mixed species of arbuscular mycorrhizal fungi under fungicide stress

Defining sustainable agricultural practices requires an understanding of both aboveand below-ground consequences to management strategies. While alternatives to biocides are sought for the control of weeds, insects and pathogens, biocide use will continue with the goal of reducing quantities used in an integrated approach. The impact of three fungicides on plant growth, seed yield, seed nutrien...

Arbuscular Mycorrhizal Fungi and Alien Plant Species

The invasion success of alien plant species depends, amongst other things, on their functional traits [4] and the susceptibility of ecosystems. There is now increasing interest in including biotic interactions particularly mutualistic associations [5], into frameworks assessing alien plant invasions, as they help bridge the invisibility and invasiveness features. The great majority of terrestri...

Plant coexistence mediated by arbuscular mycorrhizal fungi

Recent research has indicated the importance of arbuscular mycorrhizal fungi (AMF) in mediating plant coexistence. Coarse-scale studies compare the effects of the presence versus absence of AMF on plant coexistence, a phenomenon that is most relevant in early successional ecosystems where AMF are patchily distributed. By contrast, fine-scale studies investigate interactions that might occur onc...

Effects of Arbuscular Mycorrhizal Fungi on Growth and Nutrient Uptake of Apple Rootstocks in Calcareous Soil

The effects of three Arbuscular Mycorrhizal Fungi (AMF) species (Glomus versiforme, Claroideoglomus etunicatum and Rhizophagus intraradices) were studied on the growth parameters and nutrient uptake of three apple rootstocks (M.9, M.7 and MM.106). The soil medium contained a high level of calcium carbonate (38.65%). The results showed that AMF inoculation could increase almost all growth parame...

Effects of Arbuscular Mycorrhizal Fungi and Soil Conditions on Crop Plant Growth

We investigated the effects on various crops of inoculation with species of arbuscular mycorrhizal fungi (AMF) in soils from different sources and selected AMF species suitable for domestic environment-friendly farming. Effects on plants varied with the AMF species used. In carrot, Scutellospora heterogama, Acaulospora longula, and Funneliformis mosseae had a positive effect on growth of the ho...
