The present study was intended to improve the chemical properties of a saline-sodic soil using the individual application of alfalfa residue and two biochars produced from sugarcane bagasse and walnut shell, at the weighting ratio of 5%; their concomitant application with gypsum, aluminum sulfate and the mixture of these two chemical amendments was considered. The experiment was conducted in th...
Three Ohio soils, Hoytville clay, Brookston silty clay loam, and Wooster silt loam located at various branches of the Ohio Agricultural Research and Development Center, were studied. Bulk samples from each horizon were tested for exchangeable basic cations, pH, sulfuric acid extractable potassium (K+), and particle-size distribution. The surface horizons of each soil were characterized by measu...
This study conducted in Aljabal alakhdar (Green Mountain), Derna, Libya. It is the only wet region Like other Mediterranean forests, it exposed to risk of fires. To assist this, two different geographical units from (coastal and mountain), which been burned at times; identify whether these soils are regaining their pre-burn status over time. The studied properties were: soil clay content, organ...
Hypertension accompanying diabetes mellitus may involve abnormalities in at least two major blood pressure-regulating systems: the body sodium-fluid volume state and cardiovascular reactivity. In metabolically stable nonazotemic diabetes, exchangeable sodium is increased by 10% on average, regardless of age, insulin dependence or nondependence, or the presence or absence of diabetic retinopathy...
Kinetical study on non-exchangeable potassium (NEK) release is necessary for management, optimum use of soil resources, availability and supplying power of potassium. Information about NEK release rate in Golestan soils is limited. The aim of this study was to investigate the NEK release of saturated soil sample by calcium using acid citric and CaCl2 extractants from 2 to 1844 h duration in 12 ...
A deficiency of potassium is frequently recognized in congestive heart failure: estimates of total exchangeable body potassium are low (Aikawa et al., 1952; Burrows et al., 1954; Moore et al., 1954; Aikawa and Fitz, 1956; Moore et al., 1956; O'Meara et al., 1957; Flear et al., 1958; Birkenfeld et al., 1958). In a series of 33 episodes of congestive heart failure in 32 patients (Flear, 1960a), v...
The combined application of potassium dihydrogen phosphate (KH2PO4) and thermally activated nano serpentine KH2PO4 zeolite could immobilize cadmium (Cd) in contaminated soils by increasing soil pH value. results showed that adding nPS700-2.0 (KH2PO4 at 700 °C, 2% addition) exhibited better performance under the same treatment condition; it reduced DTPA-Cd 57.8% exchangeable Cd 48.76%. Adding nP...
Experimental studies on the decontamination and stabilization of sludge sites sediment with calcium oxide treated disinfectant. The results research discovered that sewage Voronezh City is safe can be used as organic fertilizer for growing agricultural plants. Determination content macro-elements mineral nutrition in soil reaction its environment showed application fertilizers form increases am...
Response of Potassium (K) is boosted due to the introduction high-yielding varieties and cropping intensity. So, a pot experiment was done see allocation native added K in soils response this on rice. Seven soil samples from seven AEZs. An amount 1-kilogram taken each 28 earthen pots which 14 for cultivation rice without as control. other fertilizers applied follows Fertilizer Recommendation Gu...
