Phosphorus runoff from two water sources on a calcareous soil.

Phosphorus (P) in irrigation runoff may enrich offsite water bodies and streams and be influenced by irrigation water quality and antecedent soil surface conditions. Runoff, soil loss, and P fractions in runoff using reverse osmosis (RO) water or mixed RO and well water (RO/ Tap) were studied in a laboratory sprinkler study to evaluate water source effects on P transport. A top- or subsoil Port...

Studies upon Calcareous Degeneration

IT WILL BE SEEN FROM THE ABOVE THAT WE HAVE STUDIED THE CONDITIONS ASSOCIATED WITH THE DEPOSIT OF CALCAREOUS SALTS: (I) in connection with normal and pathological ossification, and (2) in pathological calcification as exhibited in (a) atheroma of the vessels; (b) calcification of caseating tubercular lesions; (c) calcification of inflammatory new growth, and (d) degenerating tumors; and we have...
