By analyzing some soil chemical properties such as: SOC content, macronutrients, ion mobilized Fe, this paper will focus on: (1) description of soil chemical properties at different soil horizons under two forest types; (2) analyzing differences of those soil properties and (3) analyzing the correlation between investigated soil parameters in Kon Ka Kinh National Park, Central Highlands, Vietnam.

In monogastric animals, phosphorus (P) homeostasis is maintained by regulating intestinal absorption, bone mobilization, and renal excretion. Since P is a non-renewable resource, a shortage is imminent due to widespread over-usage in the farming and animal husbandry industries. As a consequence, P efficiency should be improved in pig production. We sought to characterize the transcriptional response in re−/absorbing and excreting tissues in pigs to diets varying in calcium: phosphorus ratios.

In this study, the potential mobility of phosphorus (P) in sediment from Can Gio was investigated. Three single extractions were applied including a mild salt (NH4 Cl), an acid (HCl), and a base (NaOH) each representing different environmental factors during sediment resuspension. Other geochemical parameters were also determined. The total amount of P in the sediments varied from 320.41 mg/kg to 668.22 mg/kg in five sampling sites.

Phosphorus plays a major role in growth and development of crops and is often found limiting in almost all types of soils. Phosphorus (P) solubilizing bacteria do the vital processes of mobilization of P from its poorly available sources. In this study, the potency of five bacterial strains (2 strains of Bacillus and 3 strains of Burkholderia) have been evaluated to solubilize P from complexes of Ca-P, Al-P, Fe(II)-P and Fe(III)-P.

Phosphorus is a major limiting factor for plant growth particularly in the tropics and subtropics areas. It play an important role in many biochemical process viz., energy storage and transfer, cell division, cell enlargement and several other processes in plants. The availability of P to plants is a problem owing to its slow diffusion and high fixation in soils. Due to low solubility and mobility in soil, phosphorus use efficiency is very low ranges from 10-20% in normal soil.

Seed germination and seedling establishment are two of the most critical phases in plant development. However, the molecular mechanisms underlying the effect of phosphorus on seed germination and post-germinated growth of oilseed rape are unclear so far. Here, we report the role of BnPHT1;4 in seed germination and early seedling development of Brassica napus.

Phosphorus is often present naturally in the soil as inorganic phosphate, Pi, which bio-availability is limited in many ecosystems due to low soil solubility and mobility. Plants respond to low Pi with a Pi Starvation Response, involving Pi sensing and long-distance signalling.

Phosphorus is perhaps, amongst all the plant nutrients, the one with the most limited bioavailability in soils (approximately 6% of total soil P is readily available (Bray’s & Olsen’s P). 80 % of phosphorus is fixed by primary minerals, precipitate, adsorbed or organically complex form. Phosphorus fertilizer is usually applied in excess of plant requirement and accumulates in soils. As soils are complex and diverse chemical, biochemical and biological systems, strategies to access recalcitrant soil P are often inefficient, case specific and inconsistently applicable in different soils.

Plants acquire phosphorus from soil solution as phosphate anion. It is the least mobile element in plant and soil contrary to other macronutrients. In the present study phosphate solubilizing bacteria were isolated from rhizosphere of four different crops on Pikovskaya’s agar medium. The potential isolate was selected on the basis of reduction in pH of media and formation of halo zone. Its biochemical study was conducted which conclude that the isolate belong to Bacillus sp.

An experiment was carried out in the greenhouse conditions with Brassica juncea L. grown on alluvial soils that had previously been contaminated at different concentrations of Cu. The main purposes of the research were to determine the effects of Cu and phosphorus applications on plant growth and Cu uptake by Brassica juncea L. Mature plants were harvested for the Cu accumulation analysis. The soil samples from each growing pot were extracted by HNO3 0.
