Positive effects of AMF on soil physical characteristics (Yang et al 2017;Parihar et al 2020) and plant resistance at abiotic stress (Porcel et al 2012;Latef et al 2016) have also been widely reported.…”

Smart fertilizers: What should we mean and where should we go?

Highlights- A smart fertilizer allows to control the rate, timing and duration of nutrients release.- Nanofertilizers are powder or liquid formulations which involve the synthesis, design and use of materials at the nanoscale level.- Composite fertilizers are formulations containing nutrients mixed or coated with one or more materials that exploit synergy among materials.- Bioformulations are fertilizers containing active or dormant microorganisms capable to trigger physiological growth responses in plants.- Limited information is available for smart fertilizers on herbaceous crops in open field conditions. Abstract The current agricultural system faces several challenges, the most important being the ability to feed the increasing world population and mitigate climate change. In this context, the improvement of fertilizers’ agronomic efficiency while reducing their cost and environmental impact is one of the biggest tasks. Available literature shows that many efforts have been made to develop innovative fertilizers defined as "smart fertilizers", for which, different interpretations and definitions have been used. This paper aims to define, classify, and describe the new frontier of the so-called smart fertilizers with a particular focus on field-scale studies on herbaceous species. Most of the analyzed papers associate the "smart" concept to the controlled and/or slow release of nutrients, using both terms as synonymous. Some others broadened the concept, including the controlled release of nutrients to reduce the environmental impact. Based on our critical analysis of the available literature, we conclude that a fertilizer can be considered "smart" whenapplied to the soil, it allows control over the rate, timing, and duration of nutrients release. Our new definition is: ‘Smart fertilizer is any single or composed (sub)nanomaterial, multi-component, and/or bioformulation containing one or more nutrients that, through physical, chemical, and/or biological processes, can adapt the timing of nutrient release to the plant nutrient demand, enhancing the agronomic yields and reducing the environmental impact at sustainable costs when compared to conventional fertilizers’.

“…The formation of soil aggregations is favored by glomalin [20], [21], acting like a glue binds together the soil micro-aggregations (diameter less than 250 µm) to form stable macro-aggregations [22], [23]. This soil macro-aggregations ensure better water infiltration, reducing surface runoff, control soil erosion, reduce nutrients and organic matter losses, increase gas exchange better retention of water and minerals, especially potassium therefore, improve crop productivity [16], [24]. In addition, the hyphae network is constantly renewing itself and the dead mycelium also preserves soil structure until decomposition [25].…”

“…When the atmospheric CO2 increase, the allocation of C from the plants to AMF also increase and stimulates the growth of AMF [57]. This C demand is provided by the host plant from the C fixed through photosynthesis [16]. In addition, AMF extramatical hyphae represent 20 to 80% soil microbial biomass which consist 15% of soil organic C [58], [59].…”

“…AMF are an extremely ancient symbiosis, indeed, based on archeologic records it dates back to the appearance of terrestrial plants (460 million years ago) and would have accompanied vascular plants to colonize the terrestrial environment [13]. AMF do not only have an impact on plant growth and production but it has been also reported that they improve some soil characteristics such as soil aggregation, soil nutrients availability, water retention, microbial activities, nitrogen, carbon and phosphorus cycling and soil acidity correction [14]- [16]. Several studies have reported that they play a crucial role in plant resistance against biotic and abiotic stresses.…”

A single paragraph Arbuscular mycorrhizal fungi (AMF) establish symbiotic relationships with many crops. These soil microbiotas improve the soil fertility through the soil physical, chemical and biological properties. extending the root absorbing area. In return, the symbiont receives plant carbohydrates for the completion of its life cycle. AMF also helps plants to cope with biotic and abiotic stresses such as extreme temperature, heavy metal, diseases, and pathogens. For soil physical properties, the mechanisms used by AMF are the production of a glycoprotein, glomalin, which creates a high quality of soil macro-aggregations. These macro-aggregations control soil erosion, nutrients and organic matter losses. For soil chemical properties, AMF produce acids and an enzyme called phosphatase. This enzyme hydrolyzes the inorganic phosphorus and the rock phosphate (RP) hence making P available in the soil for plant uptake. AMF also are involved in soil nitrogen, carbon and trace element cycling. Regarding the biological component of the soil, AMF influence the composition, diversity and activity of microbial communities in the hydrosphere. They also work in synergy with others soil microorganisms to improve soil fertility, plant growth and resistance against some diseases. In this review, we present the contribution of AMF on soil fertility and importance in polluted soils.

“…Furthermore, bacteria and fungi promote improvements in soil structure that favor aggregation and porosity (Hashim et al, 2020;Muchane et al, 2018). For example, when associated with plant roots, arbuscular mycorrhizal fungi (AMF) improve soil aggregation via hyphae and the production of glomalin (Parihar et al, 2020). This glycoprotein is important for the aggregation and storage of soil carbon and nitrogen (Sekaran et al, 2021, Wang et al, 2017.…”

Water erosion is one of the main forms of soil degradation, causing economic, environmental, and social damage. This study evaluated the effects of different formation stages of gullies (initial - IG; juvenile- JG; mature - MG; and senile - SG) on the chemical, organic carbon and microbiological attributes of soil, using a secondary forest (SF) and two areas of pasture as references in the “Mar de Morros” environment of the Brazilian Atlantic Forest biome. Soil samples (depth 0–0.05 m) were collected at the end of the rainy and dry seasons. Gullies in different stages of formation promote a decrease in soil fertility and modification of microbiological attributes, particularly when compared with secondary forest areas. Reductions of over 60% in total organic carbon (TOC), oxidizable organic carbon (POXC), FDA activity, β-glycosidase, acid phosphatase, C and N from microbial biomass, basal soil respiration (BSR) and glomalin-related soil protein (GRSP) were observed in gullies in early (IG) and intermediate (JG and MG) stages when compared to SF. It was found that the effect of erosion on soil chemical and microbiological attributes is more intense in gullies in the initial and intermediate stages compared with those in the senile stage (SG). Using multivariate PCA, the microbiological and chemical attributes of the soil are discriminated between gullies with distinct formation stages. Chemical attributes, TOC, POXC, FDA activity, β-glycosidase, acid phosphatase, MBC and MBN, BSR, and GRSP are good indicators for evaluating the process of erosion stabilization in gullies.
