We compared the effects of forest fertilization with wood ash and potassium (K) sulphate on growth and mycorrhizal colonization of fine roots and on other soil microorganisms in Norway spruce (Picea a...
Zeolite and vermicompost applications to soil may improve K fertility of soils. For this purpose, these materials were added to five representative calcareous soils collected from southern Iran. The t...
Amounts of potassium (K) fixed in soil fractions of 10 calcareous soils of southern Iran were measured to evaluate the contributions of different soil size fractions to K fixation. Soil particles were...
We examined the effect of reduced application of phosphate and potassium fertilizers on sugar beet production in brown andosol fields in the Abashiri area of Hokkaido in 2001∼2003. We could not...
The current paper reports about the influence of different levels of fertilization and agricultural practices (i.e. shallow and deep ploughing) on the total content of potassium (Ktot) and its forms i...
The objective of this study was to evaluate the fixation of ammonium in the soils of Tokat region to find out the important factors influencing them. For this purpose 12 representative soil samples we...
The main purpose of this study was to determine the effect of potassium and magnesium fertilization on the yield and N, P, K, Mg, Fe, Cu, Zn, Mn contents of rice crop grown on soil used for cultivatio...
Due to its semi-arid climate and sloping topography, Eastern Anatolia has limited soil resources for agriculture, strongly necessitating sustainable land management. Fertile soils occur only in limit...

Potassium (K) exchange isotherms (quantity-intensity technique, Q/I) and K values derived from the Q-I relationship provide information about soil K availability. This investigation was conducted to ...
Application of FYM increased dry matter %, protein % and specific gravity of tubers in both seasons. Foliar and soil K addition decreased dry matter % in tubers, but increased protein % significantly ...
Effects of potassium (K), magnesium (Mg), and sulphur (S) containing fertilizers on root yield, refined sugar yield, and K, Mg, and S concentrations of leaf of sugar beet (Beta vulgaris L.) were studi...
Conservation-tillage practices have renewed interest in research evaluating fertilization responses of cotton. Research was conducted to evaluate the cotton-yield response to P and K fertilization und...
Research to delineate nitrogen, potassium, and mepiquat chloride (MC) effects on cotton performance has been primarily conducted with upland cotton (Gossypium hirsutum L.). A field study was conducted...
Potassium fertilization meeting the uptake requirements of the fast-fruiting cotton (Gossypium hirsutum L.) cultivars requires information on soils of varying extractable K levels, tillage systems, an...
