Nutrient uptake estimates for woody species as described by the NST 3.0, SSAND, and PCATS mechanistic nutrient uptake models

Nutrient Uptake by Woody Root Systems

The fine-root system of perennial, dicot woody species can be dominated by brown roots. Although as much as 90% of the surface area of a root system can be in this category of roots, the nutrient uptake characteristics of brown roots are not well understood. If this part of the root system has active uptake, then its significance is obvious. If it does not then modelling predictions of nutrient...

The Efficiency of Integrated Pre-Emergence and Post-Emergence Herbicides in Nutrient Uptake by Wheat and Nutrient Depletion by Weeds in Sesame-Wheat Cropping System in Khuzestan

In order to investigate the effect of pre-emergence and post-emergence herbicides on nutrient depletion, weed population and nutrient uptake by wheat in sesame-wheat cropping system in Khuzestan a field experiment was conducted in randomized complete block design with three replications in the research farm of Shahid Chamran University of Ahvaz in 2019-2020. Treatments included no weeding, hand...

Nutrient Relations: Uptake and Location

Nutrient uptake of peanut genotypes under different water regimes

Drought is a serious environmental stress limiting growth and productivity in peanut and other crops. Nutrient uptake of peanut is reduced under drought condition, which reduces yield. The objectives of this study were to investigate nutrient uptake of peanut genotypes in response to drought and to estimate the relationship between nutrient uptake and peanut yield under different water regi...

Nutrient Uptake in Rust Fungi

Nutrient uptake in obligate parasitism was recently reviewed by Bushnell and Gay (5) for the powdery mildews. In the rust fungi, the experimental approach to solving this question is quite different, because the fungus mycelium grows only in restricted areas within the leaf. The rust pustules act as foci for the accumulation of many metabolites. The fungus derives nutrients by alteration of the...
