Macadamia (Macadamia spp.) has been widely planted in southern China and has been now developed into an important has the largest area of macadamia plantation in the world but provides only 3% production of the world. Current farming systems have a fertilizer surplus of about 73 g of nitrogen (N), g of phosphorus (P), and 24 g of potassium (K) per macadamia plant per year in. The purpose of this work was to determine the relative importance of mass flow and diffusion in supplying nutrients to wheat plants and to calculate nutrient uptake rates by roots (inflow). Winter wheat was grown in the field and measurements of plant Na, K, Ca, Mg, P, S and N contents, root length, plant water uptake and soil solution.
The Root Uptake Efficiency (RUE) and plant Nutrient Use Efficiency (NUE) for macro- and micronutrients in E. dysenterica seedlings were differentially affected by the availability of N and P in the soil (Figure 5, Figure 6 and Figure 7). The increase in the N rate positively affected the RUE-N and RUE-Mg at the highest rate. Nitrogen and phosphorous are critical determinants of plant growth and productivity, and both plant growth and root morphology are important parameters for evaluating the effects of supplied nutrients. Previous work has shown that the growth of Acer mono seedlings is retarded under nursery conditions; we applied different levels of N (0, 5, 10, and 15 g plant-1) and P (0, 4, 6 and 8 g plant

Katia R. Prieto, Miguel J. Beltran-García, in Plant Macronutrient Use Efficiency, Abstract. Nutrient use efficiency (NUE) depends on the plant’s ability to take up nutrients efficiently from the soil, but also depends on internal transport, storage and remobilization of nutrients.
Nitrogen (N) is a fundamental element regulating plant growth and development. The role of roots in obtaining high crop production levels as well as a high nutrient use efficiency is discussed.
Mathematical models of diffusion and massflow of solutes towards roots are. Root system architecture has received increased attention in recent years; however, significant knowledge gaps remain for physiological phenes, or units of phenotype, that have been relatively less studied.
Ion uptake kinetics plant production and nutrient use efficiency book have been invaluable in uncovering distinct nutrient uptake systems in plants with the use of Michaelis-Menten kinetic by: 2.
Enrichment of soil with plant nutrients through organic mulching materials boosts crop production. Furthermore, mulching helps in moderating the soil thermal regime, which has profound influence on nutrient transformations in soil, root growth and nutrient uptake by crop plants and thus it enhances the nutrient use efficiency by crops.
The present book Roots Plant Nutrients: Uptake, Use Efficiency and Management” contains 20 articles by eminent researchers of various countries on different aspect of the subjects. plant traits and their interactions with external factors such as soil moisture and temperature, light, best management practices, soil biological, and fertilizer ma-terials need to be more throughly evaluated to improve the NUE in plants.
NUTRIENT USE EFFICIENCY IN PLANTS Table 1. Goals / Objectives The long-term objective of this project is to develop an improved understanding of fundamental aspects of root physiology in order to increase productivity and quality of nursery and small fruit crops.
The three primary objectives are as follows. (1) Define abiotic and biotic parameters that regulate nutrient and water uptake and use in nursery and small fruit production.
This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects.
The role of roots in obtaining high crop production levels as well as a high nutrient use efficiency is discussed. Mathematical models of diffusion and massflow of solutes towards roots are developed for a constant daily uptake requirement.
Analytical solutions are given for simple and more complicated soil-root geometries. Therefore, understanding root biology and the root microbiome will lead to the ability to improve the coordination among these intimate communities to make intelligent choices in plant breeding for improved root function to improve water use efficiency, nutrient uptake, and pathogen inhibition over a range of abiotic and biotic stresses.
This. The third edition of a standard resource, this book offers a state-of-the-art, multi-disciplinary presentation of plant roots. It examines structure and development, assemblage of root systems, metabolism and growth, stressful environments, and interactions at the rhizosphere. Reflecting the explosion of advances and emerging technologies in the field, the book presents developments in the.
MECHANISMS UNDERLYING MORPHOLOGICAL ROOT RESPONSES TO NUTRIENTS AND THEIR IMPLICATIONS FOR NUTRIENT ACQUISITION. The three-dimensional arrangement of the root system of dicotyledonous plants, established by the length and thickness of the primary root and the density, length, thickness, and angles of lateral roots (LRs) of different orders, determines the soil volume that is explored by a plant.
Nutrient Root Interception Mass Flow Diffusion Nitrogen nutrient uptake process. Uptake of nutrients by a plant root is an active process. As water is taken up to support transpiration, nutrients may be moved to the root surface through mass flow.
Improved root water and nutrient acquisition can increase fertiliser use efficiency and is important for securing food production.
Root nutrient acquisition includes proliferation, transporter function, exudation, symbioses, and the delivery of dissolved nutrients from the bulk soil to the root surface via mass flow and diffusion.
The widespread adoption of simplified experimental systems has. Nitrogen (N) is one of the key mineral nutrients for plants and its availability has a major impact on their growth and development.
Most often N resources are limiting and plants have evolved various strategies to modulate their root uptake capacity to compensate for both spatial and temporal changes in N availability in soil. The main N sources for terrestrial plants in soils of temperate.

J Environ Qual – doi: /jeq This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects.
Conveying an in-depth understanding of the topic will. Abstract. There are many ways in which plants can adapt or respond to nutrient stress. These can be via alterations to root branching and root extension rates, rate of uptake per unit root length or root dry weight, partitioning between roots and shoots and between shoots and grain and the amount or concentration of the nutrient required for plants to function.
Efforts to increase efficient nutrient use by crops are of growing importance as the global demand for food, fibre and fuel increases and competition for resources intensifies.
The Molecular and Physiological Basis of Nutrient Use Efficiency in Crops provides both a timely summary of the latest advances in the field as well as anticipating. During a plant's lifecycle, the availability of nutrients in the soil is mostly heterogeneous in space and time. Plants are able to adapt to nutrient shortage or localized nutrient availability by altering their root system architecture to efficiently explore soil zones containing the limited nutrient.
It has been shown that the deficiency of different nutrients induces root architectural and.The production of high-quality seedlings and their use in commercial planting reduce pressure on natural areas.
