due to the limited availability of phosphorus in soil especially calcareous soils, it is important to investigate strategies to increase ability of phosphorus uptake by plant. evaluating the effect of zeolite (clinoptilolite), irrigation levels and preferential flows, simultaneously and independently, on increasing phosphorus uptake by corn was objective of this study. potted study was done in ...

Increasing of water consumption and demand for irrigation water in agriculture has led to an increase in reuse of treated, or even raw, municipal and industrial wastewater in many countries. Heavy metals (HMs) in these unconventional waters are one of the sources of pollution of water, soil and plant. HM toxicity in plants may eventually cause disturbances in plant growth. Accumulation of HMs i...

Iron oxide-coated strips (Pi) can serve as a sink to continuously remove P from solution. In this way, probably, P extraction is analogous to P absorption by plant root. The objective of this study was to evaluate the iron oxide-coated paper strips to estimate the availability of soil P of corn (Zea mays) grown under greenhouse conditions in some soils of Hamadan Province. Sixteen soil samples ...

Cadmium is a toxic element in plant nutrition and is considered as a contaminant of food and feed. A greenhouse experiment was carried out to examine the effects of combined application of cadmium and zinc on responses of wheat on a clay loam soil texture. This experiment was designed in a factorial experiment with randomized complete block design (RCBD) and four replicates per treatment. Three...

Background and Purpose: Soil remediation in contaminated soils is an important factor of environmental research. This research evaluated the effect of sepiolite, palygorskite, and triple super phosphate (TSP) on decreasing the heavy metals uptake by wheat cultivars inoculated with Piriformospora indica (P. indica). Materials and Methods: Treatments included applying sepiolite, palygorskite (at...

the water relations play a fundamental role in seed comprehension of biology. in order to describe the process of drying and the effect on water activity, which controls biological change in storage, a sound knowledge of the relationship between equilibrium moisture content (emc) and water activity/equilibrium relative humidity (erh) is essential. the relationship between the total moisture con...

The aim of this study was to assess the effects of heavy metal tolerant soil microbes inoculation on growth and metal uptake of pearl millet (Pennisetum glaucum), couch grass (Triticum repens) and alfalfa (Medicago sativa) in a soil spiked (and subsequently aged) with increasing concentrations of Pb. A soil sample (soil 1) was spiked with increasing (0 to 1500 mg/kg) concentrations of Pb and in...

background: phytoremediation is one of the methods used to remove contaminants and while being simple, cheap and efficient, does not cause environmental deterioration. the aims of this study were phytoremediation of soil contaminated by cd, the simultaneous survey of the influence of different electrical conductivity values, and comparison of two soil amendments including sludge and municipal c...
