MINERAL SUPPLY. "The external hyphae of AM fungi contribute up to 80% of the P, 10% of the K, 25% of the Zn, and 60% of the Cu absorbed by the plants, and 25% of plant N." https://lnkd.in/e7Tq5KC View in LinkedIn

MINERAL SUPPLY. "The crucial role of mycorrhizal fungi in improving the mineral nutrition of their host plants is well established. Mycorrhizal roots take up P, N, Zn, Cu, Ni, S, Mn, B, Fe, Ca, and K from soil more efficiently than nonmycorrhizal roots, especially at low fertility levels." https://lnkd.in/e7Tq5KC View in LinkedIn

MINERAL BALANCE. "When soil resources, such as P or N, limit photosynthesis, C is in excess. Mycorrhizal fungal hyphae explore the soil volume for P and N, and transport the nutrient (over distances of cm to m) in exchange for excess plant C. Mycorrhizal hyphae are more efficient at exploring the soil volume than even fine roots. As long as P or N are limiting, plants will support mycorrhizal fungi." https://lnkd.in/e7Tq5KC View in LinkedIn

BLACK MARKET IN P. "Phosphorus was apparently transported via underground mycorrhizas, as phosphate in direct contact with soil is immediately adsorbed to soil particles and does not move any more." https://lnkd.in/en3p-yV View in LinkedIn

BLACK MARKET IN P. "That phosphate is free to move between plants was demonstrated when radioactive phosphorus applied to the leaves of one plant, was shortly after application discovered in the shoots of neighbouring plants." https://lnkd.in/en3p-yV View in LinkedIn

PHOSPHATE DEFICIENCY. "Plant roots alone may be incapable of taking up phosphate ions that are demineralized in soils with a basic pH. The mycelium of the mycorrhizal fungus can, however, access these phosphorus sources, and make them available to the plants they colonize. Thus many plants are able to obtain phosphate, without using soil as a source." https://lnkd.in/eXuU-Hn View in LinkedIn

"MYCORRHIZAE by increasing P and N uptake, create a C sink and enhance the photosynthetic machinery. Mycorrhizae also increase water throughput, opening the stomates. Together, these increase the rates of total carbon gain by 10% to 40%." https://lnkd.in/e7Tq5KC View in LinkedIn

CARBON ENERGY. "Energy, in the form of C compounds, is the currency for exchange of soil resources. Photosynthetic rates depend on the concentrations of N (as RuBP carboxylase and other enzymes), P (for ATP, ADP), Fe and Mg (for chlorophyll), internal CO2, and water (to keep stomates open to fix CO2)." https://lnkd.in/e7Tq5KC View in LinkedIn

MINERAL BOTTLENECK. "Soil resources tend to limit plant growth. No additional C can be fixed if water, N, or P cannot be acquired in sufficient quantities. Even in rich soils, as plant numbers increase per unit soil, resources per plant decline. Second, mycorrhizae alter the competitive outcomes between mycorrhizal plants, and between mycotrophic and nonmycotrophic plants." https://lnkd.in/e7Tq5KC View in LinkedIn

NUTRITIONAL EXCHANGE. "Plants depend on mycorrhizal fungal filaments to supply them with a stunning proportion of their needed water and minerals. In some forests, these fungi provide the plants with up to 80% of their nitrogen and 90% of their phosphorus. The fungi, in turn, depend on plants to provide them with organic compounds needed for their own growth." https://lnkd.in/e4xrzsX View in LinkedIn
