Few studies have examined the use of poultry litter as an alternative to inorganic P and K fertilizers for flood-irrigated rice. The objective of this study was to compare fresh and pelletized poultry litter to inorganic P and K fertilizers to document the availability of P and K in poultry litter. Inorganic P and K fertilizers, fresh broiler litter, and pelletized litter were preplant-incorpor...

Introduction: Nakhlites are olivine-augite cumulates that formed in flows or shallow intrusions of basaltic magma on Mars [1]. There have been at least 6 independent attempts to determine the composition of the Nakhla parent magma, and at least 14 variants have been published [2-12]. Four distinct methods have been used: 1) mass balance; (2) augite/melt element partitioning; 3) melt inclusions ...

Linking potassium (K) balance to soil fertility creates a valuable indicator for sustainability assessment in agricultural land-use systems. It is crucial for the efficient use of K resources, food security and resource sustainability to realize soil K balance status in China. Therefore, temporal and spatial changes of K balance for farmland in China from 1980 to 2015 were analyzed at national ...

The effect of K2O on viscosity in CaO-SiO2-Al2O3 melt has been measured by a rotating spindle viscometer. It is indicated from the experimental results that viscosity first increases then decreases with the increasing content of K2O; the maximum viscosity occurs in the field of K2O/ Al2O3 > 1. After gradually adding K2O, the transformation of bridging oxygen (from being bonded with Al ion charg...

Patikaraparpam, a Siddha formulation in prepared by trituration of potash alum with egg albumin followed by calcinatin. The three authentic laboratories made parpams as well as six commercial samples have been examined for their chemical composition. The analytical data that emerged from the analysis of the above samples showed that seven parpams contained only aluminium sulphate and they did r...

Th e response of diff erent fertilizer doses was studied on the ratoon crop as well as main crop. Th e diff erent fertilizer doses under the study were F1 (N=90, P2O5 = 45, K2O=50, S=13, Zn = 4: in kg ha-1), F2 (N=105, P2O5 = 55, K2O=60, S=13, Zn = 4: in kg ha-1), F3 (N=120, P2O5 = 65, K2O=70, S=13, Zn = 4: in kg ha-1), F 4(N =135, P2O5 =75, K2O=80, S=13, Zn=4: in kg ha-1) and F5 (N=150, P2O5 =...
