Magnesium contents of soybean (Glycine max) roots increase and the K and Ca contents decrease with increased MgCl(2) concentrations in ambient solutions. The Mg uptake is inhibited when both Ca and K are present in the solution, but not by K or Ca alone. Chloride uptake, which is very low from the MgCl(2) solution, is greatly enhanced by the presence of K. The selectivity against Mg imparted by...

In Cambodia, cassava is mostly grown with little or no fertilizer inputs, but the magnitudes of nutrient balances are not known. This study was conducted to assess nutrient balances for cassava cultivation in Kampong Cham province in Northeast Cambodia. Forty five households in four cassava production zones were interviewed in relation to their cultural practices and crop residue management...

Despite the increasing rate of nanoparticles (NPS) production and their application in agriculture, few studies have focused on their effect on plant growth. So, the present research was conducted in laboratory and greenhouse conditions. First, superparamagnetic iron oxide nanoparticles (SPIONS) with a humic acid coating (Fe3O4/HA) were synthesized in laboratory...

Intranasal route, ensuring suitable bioavailability of medicines under circumvention of the gastrointestinal degradation and hepatic first-pass elimination, has been a popular choice for drug delivery. Among nasal dosage forms, mucoadhesive solid inserts have been shown to resist mucociliary clearance and provide a prolonged nasal residence time. Hence, the purpose of this study was the prepara...

Vegetative plants of certain seaweeds were collected from the natural habitat of Kilakarai and Mandapam coast were subjected to SEM-energy dispersive spectroscopic analysis and quantified the following minerals viz., Na, Mg, Si, S, Cl, K, Ca, Mn, P, Fe, Zn and Cr during summer, pre-monsoon, monsoon and post-monsoon seasons in 2007-2008. The order of preferential accumulation of elemental compos...

Introduction Soil microplastic (MP) pollution has emerged as a main factor of global change, but its effects on soil nutrient availability and uptake by crops (macro micronutrients) are largely unknown. Arbuscular mycorrhizal fungi (AMF) regulators can interact with MP. Materials Methods Building previous studies, here we explored in 50-days pot experiment the influence interaction MP fibres (0...

The addition of organic compounds to fertilizers has shown positive effects on plant metabolism. This study aimed evaluate the macronutrient accumulation and productivity potato with use biofertilizer (BF) applied leaves. A 2×7 factorial plot a subdivided in time ten replications used two forms fertilization: chemical fertilizer conventional NPK (nitrogen, phosphorus potassium: control) plus bi...

Application of biochar alters availability of nutrients and acidic cations in soils which in turn could affect growth of plant to different degrees. Effect of rubber wood biochar amendment on the growth and nutritional status of Hevea nursery plants was determined in this study. Biochar were applied at 1% and 2% (w/w) with and without the recommended rates of N and Mg liquid fertilizers (LF). T...

Rock colonization by plant roots and their associated microbiota is one of the major drivers of mineral weathering, nutrient cycling, soil formation and ecosystem stability. Yet the mechanisms of biouptake of lithogenic elements from rocks with differential nutrient availabilities and limitations are yet to be established. Here we present results from a mesocosm experiment that examined lithoge...
