“…Thus, these symbionts modify the resistance of plants to disease, reduce the impact of pathogens and improve the overall integrity of crops [43,44]. They also act as indirect support for plant growth and development [45,46], by changing the phosphorus mechanism and partially the replacing use of fertilizers.…”

Arbuscular mycorrhizal fungi (AMF) are beneficial for plant development and help absorb water and minerals from the soil. The symbiosis between these fungi and plant roots is extremely important and could limit crop dependence on fertilizers. The aim of this study was to evaluate the influence of AMF on tomatoes (Solanum lycopersicum L.), based on important agronomic traits of vegetative biomass, production, and fruits. The experiment was conducted in high tunnels, using 12 tomato genotypes under three different treatments: T1, control, without fertilizer and mycorrhizae colonization; T2, fertigation, without mycorrhizae colonization; and T3, arbuscular mycorrhizal fungi (AMF), seedling roots being inoculated with specialized soil-borne fungi. Plant growth, yield and fruit parameters indicated better results under mycorrhizal treatment. Root colonization with fungi varied significantly depending on the treatment and genotype, with a variation of 6.0–80.3% for frequency and 2.6–24.6% for intensity. For a majority of characteristics, the mycorrhization (T3) induced significant differences compared with the T1 and T2 treatments. In addition, AMF treatment induced a different response among the genotypes. Among the elements analyzed in the soil, significant differences were observed in phosphorous levels between planting the seedlings and after tomato harvesting and clearing of the plants. The results suggest that reducing fertilizers and promoting the symbiotic relationships of plants with soil microorganisms may have beneficial consequences for tomato crops.

“…Plant P uptake of AM plants was lower compared to control plants. This is in contradiction to one other study, investigating the effect of mycorrhizae on struvite solubilisation, which found an increased P benefit to tomato plants fertilised with struvite (Di Tomassi et al 2021). It is known that not all plant species respond positively to AM in terms of biomass development and P uptake (Hoeksema et al 2010).…”

“…The factor contributing to the observed pH decrease inside some of the compartments in this experiment is not clear. Although organic acid exudation by mycorrhizae has been hypothesised, evidence supporting this hypothesis has not been confirmed yet and further investigations are required (Di Tomassi et al 2021;Tawaraya et al 2006). A more indirect influence on the acidification of the mycorrhizal compartment by AM releasing hydrogen ions seems more likely (Bolan 1991).…”

To reduce dependency on inorganic phosphorus (P) fertiliser, secondary P fertilisers such as struvite are becoming more important. However, the P uptake of these new fertilisers by plants is often not known and may be enhanced by plant associated microorganisms. We therefore investigated the effect of arbuscular mycorrhizae (AM) on P uptake in rye (Secale cereale L.), grown in the middle compartment of a box with chambers separated by a 30 µm mesh allowing fungal hyphae but not roots to penetrate. Plants with (AM) or without (control) mycorrhizae (Rhizophagus irregularis) were grown in a P limited sand medium for 72 days. After harvest, plants were analysed for mycorrhizal colonization, shoot and root development and nutrient (P, Ca, Mg) uptake. Further, pH was measured in each compartment. Shoot biomass of both treatments was not different, but root biomass was significantly lower in AM plants. Despite plants of the AM treatment being colonised by mycorrhizae, their P uptake was substantially lower compared to the control treatment, but root nutrient concentration was higher. Even though the pH in the mycorrhizal compartment of the AM treatment was significantly lower compared to the control, water- and CAL-extractable P were similar, indicating little P uptake from this compartment. Extractable P was reduced only in the root compartment of the control, which was associated with a lower pH compared to the AM treatment. In conclusion, mycorrhizae did not increase P uptake from struvite in rye plants. Non-mycorrhizal plants which invested more biomass into roots took up more P. Graphical abstract

“…Partial dissolution of struvite over the course of a growing season is well supported, and one evaluation on the same soil type as our Urbana site (Typic Endoaquoll) over the course of spring application to maize ( Zea mays L.), totaling 138 d, found dissolution of struvite assessed by recovering and weighing remaining granules to range from 50%–65%, and complete dissolution of MAP (Gu et al., 2021). At a shorter timescale of 72 d under tomatoes ( Solanum lycopersicum L.) grown in pots with the A horizon of a similar soil type (Aquic Argiudoll), struvite dissolution was only 22%, 4‐fold lower than MAP (Di Tomassi et al., 2021). Given these quantified dissolution differences between struvite and MAP, a struvite P mass balance <100% supports our hypothesis that lower dissolution of struvite would result in the partial P and N recovery.…”

Struvite (MgNH4PO4·6H2O) is a wastewater‐derived phosphorus (P) fertilizer with potential to reduce P as well as nitrogen (N) losses due its low water solubility. To test hypothesized lower P and N losses from struvite relative to monoammonium phosphate (MAP), field experiments with a randomized‐complete block design were conducted at two locations, on a Endoaquoll‐Argiudoll complex (Urbana, IL) and a Fragiudalf‐Hapludalf complex (Ewing, IL). Fertilizer was broadcast applied in the fall prior to spring planting of soybean (Glycine max L.) at a maintenance rate of 29.5 kg P ha−1 (Urbana) and 22.0 kg P ha−1 (Ewing). In the spring, soil extractable N and Mehlich 3‐P at 0–15 and 15–35 cm depths were determined, and leached N and P were estimated using fall‐installed ion‐exchangeable resin (IER) lysimeters. At Urbana, soil extractable nitrate‐N was higher under MAP than struvite at the 0–15 cm depth. At Ewing, soil Mehlich 3‐P under struvite was lower than MAP at both depths. At Urbana, leached P was 10‐fold lower and leached N was 2‐fold lower under struvite than MAP. Soybean yields were similar between MAP and struvite at Urbana (4.1‐4.3 Mg ha−1) and Ewing (3.2‐3.5 Mg ha−1), but at Ewing were 23% higher under struvite compared to the P‐unfertilized control. Off‐season yield‐scaled P and N losses under struvite were lower than MAP by 51% at Urbana and by 10% at Ewing. Our results support the hypothesized potential of struvite to reduce nutrient losses while meeting crop P needs. Additionally, we identify disproportionally greater reductions in N leaching and yield‐scaled N losses by substituting struvite for MAP in fall applications, indicating that struvite may offer greater relative benefits for N loss reductions than P loss reductions.This article is protected by copyright.
