Awareness of the effects of fire on various aspects of an ecosystem after the fire,is important for range management. Changes in soil physical and chemical propertiescaused by fire can be the cause of changes in the vegetation. In this study, effects of fire onphysical and chemical characteristics of soil were investigated. This research was carriedout in a randomized block design method in the...
background: routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. we figure that repeat testing of critical laboratory values has any benefits or not. methods : we examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white b...
Food production requires application of fertilizers containing phosphorus, nitrogen and potassium on agricultural fields in order to sustain crop yields. However modern agriculture is dependent on phosphorus derived from phosphate rock, which is a non-renewable resource and current global reserves may be depleted in 50–100 years. While phosphorus demand is projected to increase, the expected gl...
Screening and Preliminary Identification of Soil Potassium and Phosphorus-hydrolyzing Bacteria WP1-3
In order to screen the strains with Potassium and phosphorus-releasing bacteria from soil, potassium-dissolving medium was used for preliminary screening, transparent circle method re-screening. The content of soluble potassium determined by sodium tetraphenylborate method, phosphorus anticolorimetric molybdenum antimony. were identified morphological, biochemical molecular biology. results sho...
residue management has a direct impact on soil physical and chemical characteristics which in turn have identical effects on sustainability of crop production in agroecosystems. the effects of wheat residual management practices (burning, plowing under and removal) on soil physical and chemical characteristics were investigated in this research. treatments were compared in a complete block desi...
BACKGROUND Hypokalemia is a well-known, consistent finding in thyrotoxic periodic paralysis (TPP). It is less well known that hypophosphatemia and mild hypomagnesemia are often present in TPP and that rebound hyperkalemia can occur as a result of potassium therapy. OBJECTIVE To report the prevalence of these electrolyte abnormalities in 24 episodes of TPP in 19 patients admitted to a single u...
Trees decline is a complex physiological disease that results from the interactions between several factors, one of which is heavy metal stress that ultimately leads to the death of trees. This experiment, which was conducted during 2016-2017 at the campus facility of the Department of Horticulture at Isfahan University of Technology, was conducted to investigate the effects of inoculation with...
During the kharif season of 2018, a field experiment titled "Influence phosphorus and potassium in combination with biofertilizers on growth cowpea [Vigna unguiculata (L.) Walp]" was carried out at crop research farm Division Agronomy, Faculty Agriculture, Sher-e-Kashmir University Agricultural Sciences Technology Kashmir. The soil experimental had texture clay loam, neutral reaction (pH 6.9), ...
The optimization of soil sampling is very important in precision agriculture. main aim this study was to evaluate the relationships between selected spectral indices (NDWI—normalized difference water index and NDVI—normalized vegetation index) apparent electrical conductivity (EC) with nutrient content (phosphorus, potassium, magnesium) pH. Moreover, usefulness these variables for delineation w...
