“…A worldwide increase in the cost of chemical fertilizer, as well as a need to decrease chemical-fertilizer runoff, makes it highly desirable to manage AM symbioses to naturally improve or sustain yields of crops and biofuel feedstocks (47). Because of the development of new carbon-negative biofuels, great advancement has been made in identifying and characterizing aboveground traits in prairie grasses relevant to the needs of biofuel feedstocks (48).…”

Symbioses may be important mechanisms of plant adaptation to their environment. We conducted a reciprocal inoculation experiment to test the hypothesis that soil fertility is a key driver of local adaptation in arbuscular mycorrhizal (AM) symbioses. Ecotypes ofAndropogon gerardiifrom phosphorus-limited and nitrogen-limited grasslands were grown with all possible “home and away” combinations of soils and AM fungal communities. Our results indicate thatAndropogonecotypes adapt to their local soil and indigenous AM fungal communities such that mycorrhizal exchange of the most limiting resource is maximized. Grasses grown in home soil and inoculated with home AM fungi produced more arbuscules (symbiotic exchange structures) in their roots than those grown in away combinations. Also, regardless of the host ecotype, AM fungi produced more extraradical hyphae in their home soil, and locally adapted AM fungi were, therefore, able to sequester more carbon compared with nonlocal fungi. Locally adapted mycorrhizal associations were more mutualistic in the two phosphorus-limited sites and less parasitic at the nitrogen-limited site compared with novel combinations of plants, fungi, and soils. To our knowledge, these findings provide the strongest evidence to date that resource availability generates evolved geographic structure in symbioses among plants and soil organisms. Thus, edaphic origin of AM fungi should be considered when managing for their benefits in agriculture, ecosystem restoration, and soil-carbon sequestration.

“…In the majority of studies, the effect of mineral fertilization has been compared to fertilization with animal manure or sludge, although there is limited data regarding the effect of soil enrichment by mycorrhizal inoculation or lignin on the productivity of SRWC compared to mineral fertilization. Mycorrhiza may increase the biomass production of SRWC, improve tolerance of abiotic and biotic stress, and increase resistance against soil pathogens [26]. Large volumes of lignin are available in the market; in 2010, the production was approximately 50 million tonnes of extracted lignin, but only 1 million tonne was commercially used for low-value products, the rest was burnt as a low-value fuel [27].…”

Effect of Increased Soil Fertility on the Yield and Energy Value of Short-Rotation Woody Crops

Biomass is produced as a feedstock for energy generation and industrial processes from short-rotation woody crop plantations in Europe, the USA, and Canada. This study determined the impact of soil enrichment on the survival rate, productivity, energy value, and yield of three species of crops grown on poor soil in a 4-year harvest rotation based on two factors: species (willow, poplar, and black locust) and fertilization (lignin, mineral fertilization, mycorrhiza inoculation, and their combination). The highest average yield was obtained from willow, followed by poplar and black locust. The highest yield in the entire experiment was for poplar with lignin combined with mineral fertilization (10.5 odt ha −1 year −1 ). Using lignin combined with mineral fertilizers increased the yield by 8-14 % compared to mineral fertilizers alone for willow and poplar and nearly doubled the black locust yield. The energy value of the yield ranged from 28.6 to 176.7 GJ ha −1 year −1 , respectively, for black locust grown on the control plot and for poplar grown with mineral fertilization combined with lignin.

“…Increasingly, reports on ecosystem services such as "soil fertility regulation" include AM as providers of nutrient supply from soil [25]. Therefore, we must better investigate the key role of mycorrhizas in ecosystem services and soil health, as explained in recent reviews [26][27][28], since they are a functional component in natural and reforested ecosystems.…”

Reforestation provides restoration of forest ecosystem services including improved soil fertility, which leads to increased productivity and/or sustainability of the system. Trees also increase the average carbon stocks providing wood supply for local communities; however, C sequestration strategies highlight tree plantations without considering their full environmental consequences, such as losses in stream flow. The productivity of a site is a consequence of their physical, chemical, and biological properties, resulting in natural fertile soils or adequate managed soils for improved quality. Thus, it is required to know the variations in the properties of land-use systems for adoptability of agroforestry innovations. The choice of agroforestry tree species (highly mycorrhizal dependent plants should be selected) would have great implications for the manipulation of arbuscular mycorrhizas's species. In dry forest, the inevitable consequence of cutting has been the loss of vegetation cover and insufficient scientific information on the capacity to optimize forest recuperation affects agroforestry adoption. To study the biological properties of soils is now of interest; therefore, this paper reviews the literature that has hitherto been published on mycorrhizal interactions for reforestation and points out the use of mycorrhizal technology as one of the alternatives to improve forest products and environmental quality.
