“…The pH of the calcareous soils where the pecan tree was established was high in all the orchards in this study. Olivas-Tarango et al [21] reported a pH of 7.5 in pecan tree soils in Chihuahua and a high presence of ectomycorrhized roots. In the study by Becerra et al [48], the greatest ectomycorrhizal colonization of Alnus acuminata occurred in soil with a pH of 6.6; in this study, the ECM percentage was measured in soils with pHs ranging from 5.6 to 6.6.…”

“…Studies on the effect of organic and conventional orchard management on the diversity of microorganisms in the soil have demonstrated that organic management promotes an increase in the diversity of arbuscular mycorrhizal fungi [28,29]. The general assumption is that a diversity of microorganisms exists, including ECM, according to the agronomic management of pecan orchards; however, there is currently limited data on the subject [21,30], some of which focused on other tree species [31,32]. There are no identified studies on the molecular identification of sporocarps inhabiting pecan orchards in Mexico or the USA.…”

Pecan trees form a symbiotic relationship with ectomycorrhizal fungi (ECM), which actively provide nutrition to the roots and protect them from phytopathogens. Although these trees originated in the southern United States and northern Mexico, information on their root colonization by ECM is insufficient in terms of a representative number of samples, both in these regions and worldwide. Therefore, the objectives of this study were to determine the percentage of ectomycorrhizal colonization (ECM) of pecan trees of different ages in conventional and organic agronomic orchards and to identify ectomycorrhizal sporocarps, both morphologically and molecularly. The rhizospheric soil properties and the ECM percentages were analyzed for 14 Western variety pecan tree orchards between 3 and 48 years of age and grouped according to the agronomic management method. DNA extraction, internal transcribed spacer amplification, and sequencing were conducted on the fungal macroforms. The ECM colonization percentage fluctuated between 31.44 and 59.89%. Soils with low phosphorus content showed higher ECM colonization. The ECM concentrations were relatively homogeneous in relation to the ages of the trees, and organic matter content did not affect the percentage of ECM colonization. The highest ECM percentages occurred with the sandy clay crumb texture soil, with an average of 55% ECM, followed by sandy clay loam soils with 49.5%. The Pisolithus arenarius and Pisolithus tinctorius fungi were molecularly identified from sporocarps associated with pecan trees. This is the first study that reports Pisolithus arenarius as being associated with this tree.

“…Even a large proportion of the applied urea is lost by volatilization, leaching, or by incorporation into the soil ( Avila-Quezada et al, 2022 ). Furthermore, some micronutrients are not available to plants ( Madrid-Delgado et al, 2021 ) mainly in calcareous soil ( Olivas-Tarango et al, 2021 ). For this reason, it is essential to have new nanotechnology-based fertilizers on the market.…”

Natural polymer-based nanocomposites have received significant attention in both scientific and industrial research in recent years. They can help to eliminate the consequences of application of petroleum-derived polymeric materials and related environmental concerns. Such nanocomposites consist of natural biopolymers (e.g., chitosan, starch, cellulose, alginate and many more) derived from plants, microbes and animals that are abundantly available in nature, biodegradable and thus eco-friendly, and can be used for developing nanocomposites for agriculture and food industry applications. Biopolymer-based nanocomposites can act as slow-release nanocarriers for delivering agrochemicals (fertilizers/nutrients) or pesticides to crop plants to increase yields. Similarly, biopolymer-based nanofilms or hydrogels may be used as direct product coating to extend product shelf life or improve seed germination or protection from pathogens and pests. Biopolymers have huge potential in food-packaging. However, their packaging properties, such as mechanical strength or gas, water or microbial barriers can be remarkably improved when combined with nanofillers such as nanoparticles. This article provides an overview of the strategic applications of natural polymer nanocomposites in food and agriculture as nanocarriers of active compounds, polymer-based hydrogels, nanocoatings and nanofilms. However, the risk, challenges, chances, and consumers’ perceptions of nanotechnology applications in agriculture and food production and packaging have been also discussed.
