Organic phosphate sorption by neutral and basic soils
Abstract The sorption of several organic phosphates were measured on soil, peat and other organic and inorganic materials. The behavior of the phosphates on these materials differed from thatExpand
COMPONENTS AND PARTICLE SIZE FRACTIONS INVOLVED IN ATRAZINE ADSORPTION BY SOILS1
We used two Saskatchewan soils to investigate the relative importance of sesquioxides, organic matter, and a series of particle size fractions in adsorbing atrazine. The DCB (sodiumExpand
Laboratory incubation studies of chlorophenoxyacetic acids in chernozemic soils
Abstract The relative persistence of 2,4-D, MCPA and 2,4,5-T in some Saskatchewan soils was assessed under laboratory conditions. Under moist conditions, 2,4-D and MCPA showed half-life times ofExpand
CHARACTERIZATION OF THE INOSITOL PENTA‐ AND HEXAPHOSPHATE FRACTIONS OF A NUMBER OF CANADIAN AND SCOTTISH SOILS
Summary The nature of the inositol pentaphosphate and hexaphosphate isomers in a number of contrasting Canadian and Scottish soils has been examined. The mixed esters were extracted fromExpand
The degradation of 14C-labelled phosphatidyl choline in soil
When phosphatidyl [N-methyl-14CO]choline or phosphatidyl choline di[l-14C]palmitoyl were incubated in a low phosphorus status soil there was an early and rapid release of CO2 and a concurrentExpand
The relative persistence of trifluralin (545 EC and 5 G) and ethalfluralin in prairie soils
The persistence in soil of trifluralin 545 EC, trifluralin 5 G, and ethalfluralin 360 EC was studied over a 2-yr period at three different sites in Saskatchewan. At two of the three sites bothExpand
CONTENT OF INOSITOL PENTA‐ AND HEXAPHOSPHATES IN SOME CANADIAN SOILS
Summary The combined amounts of inositol penta- and hexaphosphates in a number of Canadian soils of differing origin have been measured. The esters were precipitated as barium salts from alkaliExpand
Mobility of two sulfonylurea herbicides in soil
Intact field soil cores were used to compare the mobility of DPX-A7881 [2-[[[[[4-ethoxy-6-(methylamino)-1,3,5-triazin-2-yl]amino]carbonyl]amino]sulfonyl]benzoate], a new sulfonylurea herbicide, andExpand
An examination of methods for extraction of soil phospholipids
Abstract Three methods for measurement of soil phospholipid material were compared for their relative efficiencies. When applied to a few Saskatchewan soils, the Hance and Anderson (1963) method, andExpand
