Among factors affecting nutrient availability in the soil solution there are pH aeration humidity organic matter temperature and presence of other ions among others Nutrients with high mobility in the plant have a high concentration of this nutrient in the phloem as immobility in the phloem is presumably caused by the inability of
This section covers the different nutrients required for plant growth and the different root architectures and structures which help the plants maintain sufficient nutrient uptake to support the above ground biomass Plant nutrition Although the absolute quantities of nutrients required vary between plant species genotypes
Biotic and abiotic factors affecting nutrient availability total nutrient content of the soil intensity factor chemical form of nutrients absorbed by the plants mobility of the nutrient within the soil and plant antagonistic and synergetic effects as influenced by alkalinity sodicity salinity pH and use of saline and sodic waters; and
The efficient use of nitrogen N is essential for plants as it is one of the most limiting factors for plant growth Pellegrini 2016 Plant nitrogen use efficiency NUE is defined as the net dry mass production per unit of N uptake which is extensively employed for research into plant N use strategies Hirose 2011 Plants with higher NUE can better integrate limited N
Critical plant factors include plant age internal nutrient concentration and the different stages or phases of crop growth and development Under conditions of steady and nonlimiting supply of nutrients fertigation hydroponics prevalent in the controlled environment of modern rose greenhouses the plants have a tight control and
Nutrient supply of plants generally depends on both soil and plant factors Availability of the nutrients is the resultant of a complex of soil factors They interact with a group of plant properties which can be comprised under the term efficiency of uptake
To know how plant roots absorb nutrients and move inside plants Nutrients must reach the surface of a root for plant uptake of essential elements to occur concentration of nutrients and volume of soil displaced by root system Nutrients supplied primarily by diffusion are considered immobile nutrients P K Factors affecting diffusion a
Plants require mineral nutrients including the three most important macronutrients nitrogen N phosphorus P and potassium K to maintain their growth The fertilizer type used is an important factor affecting NUE 1998 A model for the lowering of plant ethylene concentrations by plant growth promoting bacteria J Theor Biol
Altitude is a determining factor of ecosystem properties and processes in mountains Changes in plant and soil nutrient concentrations along altitudinal Temperature can affect soil organic
Knowledge of plant nutrient strategies is crucial for defining and predicting the patterns and mechanisms resulting from nitrogen N deposition However the impacts of N enrichment on plant nutrient strategies are unclear in global grasslands We conducted a meta analysis of 127 publications to synthesize the pathways underlying the responses of plant
Sedimentary rock covers 75 80% of the Earth s crust and it forms parent materials for a large majority of soils Soil parent material has a significant direct influence on the nutrient element
Nitrogen is one of the most important nutrient for plant growth and development; it is strongly associated with a variety of abiotic stress responses As sessile organisms plants have evolved to develop efficient strategies to manage N to support growth when exposed to a diverse range of stressors This review summarizes the recent progress in the field of plant nitrate
However when plant tissue is chemically analyzed it is common to find approximately 50 chemical elements and not all of them are considered plant nutrients Plants have the ability to absorb chemical elements in the soil or nutrient solution with little restriction which could be a nutrient nonmineral nutrients from the atmosphere or a
Aims Foliar nutrient resorption is a critical process for considerations of ecosystem nutrient cycles Previous studies have described the independent effects of climatic factors plant and soil nutrient status on nutrient resorption However little is known about the comprehensive effects of these factors on nutrient resorption especially based on observations
There are many factors influencing plant biomass such as soil humidity soil and air temperature photoperiod solar radiation precipitations genotype One of the most important factors influencing biomass is soil nutrient availability Both nutrient deficiency and toxicity negatively affect total biomass and fruit production [1 10
Background Global climate is changing more rapidly than ever threatening plant growth and productivity while exerting considerable direct and indirect effects on the quality and quantity of plant nutrients Scope This review focuses on the global impact of climate change on the nutritional value of plant foods It showcases the existing evidence linking the effects of
Among the essential plant nutrients calcium Ca is the third most abundant after nitrogen N and potassium K Plants require Ca 1 3 mM for their normal growth and development Saito and Uozumi 2020 Ca ions Ca such as those involved in signaling plant metabolism and cell growth contribute to several biological processes that affect all steps of
Abstract Legumes and cereals contain high amounts of macronutrients and micronutrients but also anti nutritional factors Major anti nutritional factors which are found in edible crops include saponins tannins phytic acid gossypol lectins protease inhibitors amylase inhibitor and goitrogens Anti nutritional factors combine with nutrients and act as the major
Factors affecting nutrient concentration and stoichiometry of forest trees in Catalonia NE Spain which was expected in a Mediterranean climate where the availability of water is the most limiting factor for plant nutrient uptake In addition the availability of water which influences productivity was associated with low leaf N P
As an important index for morphogenesis architecture PH is susceptible to both environmental and biological interferences Environmental factors such as temperature light water gas soil and nutrients have all been reported to specifically affect the PH in addition to their impacts on overall plant development and growth
High bulk densities provide enhanced mechanical resistance to root penetration and suppress the development of seedlings Additionally bulk density has a significant impact on root respiration and the rate of oxygen diffusion into soil pore spaces both of
Factors affecting nutrient concentration and stoichiometry of forest trees in Catalonia NE Spain MAT or MAP could directly affect the plant nutrient allocations and physiological
Micronutrient deficiencies in soil have been identified as one of main factors affecting crop yield food quality and human health Soil micronutrient availability to plants is determined by micronutrient contents of soil components such as minerals and organic matters and the influence of different edaphic and biological factors such as pH redox potential
