A model for optimal mycorrhizal colonization along altitudinal gradients
Silva Fennica, 2002 Mycorrhizal associations are generally favourable for vascular plants in nutrient-poor conditions. Still, non-mycorrhizal plants are common in high arctic and alpine areas, which are often poor in nitrogen and phosphorus.

Nitrogen, Phosphorus, and Potassium Uptake in Rain-Fed Corn as Affected by NPK Fertilization
Agronomy, 2023 Effective nutrient management requires understanding nutrient uptake at various growth stages and nutrient removal by the harvested portion. Information on nutrient accumulation was provided by some older literature, and a few researchers have focused on

Modelling Water and Nutrient Uptake
, 2000 Supplying plants with inorganic nutrients and water is a major function of roots (Nye and Tinker 1977; Nielsen 1983; Barber 1984; Jungk and Claassen 1989; Gahoonia and Nielsen 1991, 1992a,b). It is still a major challenge to agricultural research to quantitatively predict production of a crop as influenced by uptake of nutrients and water.

Nutrient use and uptake in Pinus taeda [PDF]
Tree Physiology, 2008 We quantified nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) content, use (nutrient amount for one growth year), retranslocation (nutrients recycled before foliage senescence), uptake (use minus retranslocation), volume production per unit of uptake and fertilizer-uptake efficiency (percent applied taken up) in a 2 x 2 ...

Effects of different phosphorus and potassium fertilization on contents and uptake of macronutrients (N, P, K, Ca, Mg) in winter wheat II Uptake of macronutrients [PDF]
Journal of Central European Agriculture, 2014 The aim of this study was the assessment of macronutrient (N, P, K, Ca, Mg) accumulation in wheat at the critical phases of yield shaping as well as at the full ripening stage when judged at optimal P and K fertilizer rates applied as well as at reduced ...

Plants, 2023 Switching over to closed-loop soilless culture systems, thus preventing pollution of water resources by nitrates and saving water and fertilizers, requires accurate estimations of the mean nutrient-to-water uptake ratios. To contribute to this objective,

Nutrient Uptake in Supplemented Substrate by Oyster Mushroom
World Journal of Microbiology and Biotechnology, 2023 Abstract Spent mushroom substrate (SMS) can be a good alternative for the supplementation of the Oyster mushroom substrate, replacing the cereal bran normally used. Therefore, the objective was to evaluate the production of Pleurotus ostreatus supplemented with Lentinula edodes’ SMS, through the nutritional analysis of the substrate.
