Much work has been done during recent years in investigating the calcium partition in the blood of laying hens. From this work an attempt has been made to determine the nature of the non-diffusible calcium. Although Laskowski (1) and Benjamin and Hess (2) investigated the partition of inorganic phosphorus in connection with the study of calcium in the serum of the laying hen, little has been do...
Studying soil phosphorus fractions is useful in understanding soil pedogenesis as well as soil fertility. In this reseach, 20 soil samples were taken from different depths of 0-30 and 30-60 cm of upper-slope, mid-slope and lower-slope positions of four toposequences in arid (Jei and Ziar in Isfahan) and semiarid (Farokhshahr and Shahrekord) regions. In each toposequence, the soil depth was re...
