Effect of soil oxygen deficit on iron nutrition of orange seedlings.
Iron deficiency chlorosis in plants is often associated with soil conditions that appear to restrict exchange of gases with the atmosphere, such as fine texture, lack of aggregation, excessive moisture, or discontinuity in the profile in the form of plowsole, hardpan, claypan, or stratified deposits. These conditions can cause CO2 to accumulate in the soil and, particularly in calcareous soils,...
متن کاملThe effect of two humic substances on the growth and lead Uptake of corn in calcareous soil
ABSTRACT- In the past few decades, accumulation of heavy metals, such as lead (Pb), in soils has increased as a result of human activities.The environmental hazard associated with soil enrichment in heavy metals is related to their mobility and plant availability. Application of various materials such as humic may influence the amount of Pb taken up by plant. Four levels of each of liquid and s...
متن کاملComparison of Foliar and Soil Fe Fertilization on Medicago scutellata Physiological-Biochemical Characteristics and Active Iron in Soils Containing Different Amounts of Lime
Reducing iron solubility in calcareous soils causes iron chlorosis symptoms in the plant. In order to investigate the response of M. scutellata to direct and indirect iron deficiency, a factorial experiment was conducted in a completely randomized design with three replications. The experimental factors included three levels of lime (0, 4 and 8%) and five levels of Fe (0, 5 and 10 mg Fe Kg soil...
متن کاملBioaccumulation and phyto-translocation of Nickel by Medicago sativa in a calcareous soil of Iran
Abstract Nickel is a heavy metal distributed ubiquitously in nature. It accumulates in soil as a result of human activities, including mining and industries development. It may be poisonous to plants, humans, animals and microorganisms. The present study was implemented as a factorial experiment with a Randomized Complete Block Design (RCBD), of three replications in calcareous soils of Karaj...
متن کاملLime-Induced Chlorosis
Lime-induced iron chlorosis in citrus and avocado trees may be controlled by chelating agents, such as EDTA-ethylene-diaminetetraacetic acid. Chelating agents have the ability to form complex compounds with metal ions-iron, zinc, manganese, and magnesium-holding the metals in a soluble form in various degrees of tenacity. Iron is held most firmly and, for this reason, the prospects may be best ...
