Plant adaptations to severely phosphorus-impoverished soils.
Mycorrhizas play a pivotal role in phosphorus (P) acquisition of plant roots, by enhancing the soil volume that can be explored. Non-mycorrhizal plant species typically occur either in relatively fertile soil or on soil with a very low P availability, where there is insufficient P in the soil solution for mycorrhizal hyphae to be effective. Soils with a very low P availability are either old an...
متن کاملSoil Aggregate Size Affects Phosphorus Desorption from Highly Weathered Soils and Plant Growth
Wiersum, 1962; Cornforth, 1968; Misra et al., 1988), but freshly applied P may penetrate only a thin layer Because plant absorption of P depends on the desorption of P around soil aggregates (Gunary et al., 1964; Linquist et from soil, understanding P desorption from soils may improve the precision of P diagnosis and fertilization recommendations. Many al., 1997), suggesting that larger soil ag...
متن کاملPhosphate solubilizing microbes: sustainable approach for managing phosphorus deficiency in agricultural soils
Phosphorus is the second important key element after nitrogen as a mineral nutrient in terms of quantitative plant requirement. Although abundant in soils, in both organic and inorganic forms, its availability is restricted as it occurs mostly in insoluble forms. The P content in average soil is about 0.05% (w/w) but only 0.1% of the total P is available to plant because of poor solubility and ...
متن کاملPlant growth promotion induced by phosphate solubilizing endophytic Pseudomonas isolates
The use of plant growth promoting bacterial inoculants as live microbial biofertilizers provides a promising alternative to chemical fertilizers and pesticides. Inorganic phosphate solubilization is one of the major mechanisms of plant growth promotion by plant associated bacteria. This involves bacteria releasing organic acids into the soil which solubilize the phosphate complexes converting t...
متن کاملEnvironmental Growth Conditions of Trichoderma spp. Affects Indole Acetic Acid Derivatives, Volatile Organic Compounds, and Plant Growth Promotion
Trichoderma species are soil-borne filamentous fungi widely utilized for their many plant health benefits, such as conferring improved growth, disease resistance and abiotic stress tolerance to their hosts. Many Trichoderma species are able to produce the auxin phytohormone indole-3-acetic acid (IAA), and its production has been suggested to promote root growth. Here we show that the production...
