1. Simultaneous measurements of exchangeable Na+, exchangeable K+ , extracellular fluid volume and total body water, with 24Na, 43K, "Br and 3Hz0, were carried out in patients with adrenocortical insufficiency due to pituitary ablation performed 1-3 months previously. 2. The first group of five patients was studied before and after withdrawal of maintenance prednisone (2.5 mg three times daily,...

Field and greenhouse studies have confirmed that wattle brush ash may cause marked increases in yield . when sugarcane is grown in certain midland soils. This effect was associated with the following factors: (i) decreased soil acidity (ii) increased P and K uptake by the plant (iii) increased soil exchangeable Ca, Mg, P, K and base saturation values (iv) reduced soil levels of A1 and Mn (v) re...

increasing urbanisation and industrialisation have led to a dramatic reduction in forest area, and now only culturally protected remnants of natural forests and some new plantations remain in most areas of the north of iran. to investigate the status of the chemical and physical characteristics of soil under these remnant forests and assess the possible impacts of reforestation on soil properti...

Nguyen, Minhtri K., and Ira Kurtz. A new formula for predicting alterations in plasma sodium concentration in peritoneal dialysis. Am J Physiol Renal Physiol 288: F1113–F1117, 2005; doi:10.1152/ajprenal.00387.2004.—Alterations in the plasma water sodium concentration ([Na ]pw) result from changes in the total exchangeable sodium (Nae), total exchangeable potassium (Ke), and total body water (TB...

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...

Corn (Zea mays L.) grown on sandy Atlantic Coastal Plain soils is often unresponsive to applications of K fertilizer. As part of a field study on the response of irrigated, intensively managed corn to K applications, we characterized four representative Hapludults from the Delaware Coastal Plain and evaluated their K status. The soils were generally quite sandy with maximum clay contents of 11....
