Determination of heavy metal contamination in the soil environment using ion-exchange membranes
An anion exchange resin membrane saturated with chelating agent (AEM-DTPA) was used to assess the bioavailability of four heavy metals, Cd, Cr Ni and Pb via direct in soil burial. Two soils with four contamination rates ...
Assessing nutrient availability variations in landscapes
A simple method was developed to assess the variability in nutrient availability in undulating landscapes using anion-exchange resin strip burial. Resin strips were buried in ten farm fields along transects at points in ...
Assessing soil K supply capacity for wheat growth
Determination of 2,4-d amine in soils using anion-exchange membranes
A new method for the quantitative determination of 2,4-D in soils by use of anion-exchange membranes with GC detection was developed. Preliminary investigation of ion-exchange properties of pure 2,4-D acid on the membranes ...
Assessment of elemental S-sludge mixtures and waste gypsum as fertilizer sources
Two separate studies (soil incubation and growth chamber) were used to assess the release of plant available sulfate from two alternative sulfur sources: (1) combinations of finely ground elemental sulfur, dried digested ...
Nitrogen requirements of borage and coriander
Canola, borage and coriander were grown in a growth chamber with treatments of increasing rates of added nitrogen. Dry matter yield was measured at the early-flowering stage. Both borage and coriander had a lower potential ...
Influence of hog manure and fertilize N on P supply rate in soil and uptake by canola under controlled environment conditions
The effect of manure and urea on P availability to canola was investigated under controlled environment condition. Canola (B. napus) was grown in pots with manure and urea added to two Saskatchewan soils (sandy loam and ...
Effect of oily waste amendments on nutrition and growth of oats
The application of oily waste to soil may lead to undesirable conditions, which may affect plant growth. One of these conditions is nutrient deficiency resulting from the competition between plants and microorganisms ...
