This book was released on 1964 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potassium values of an appreciable number of soil samples received by the Agricultural Soil and Feed Testing Laboratory in recent years have been less than 50 lb./ac. (HAc extraction method). In order to determine whether these soils should be rated as low in potassium, greenhouse, field and laboratory studies were carried out on selected soils. Increased yields of barley occurred in the greenhouse from potassium fertilized Aa horizons of the Thin Black Solod, Wetaskiwin and Camrose soils and of alfalfa for the Wetaskiwin and Camrose soils. However, the increases of barley and alfalfa yields were small on the Winterburn soil, which tested over 50 lb./ac. of K. The Aa horizon of the Winterburn soil had the highest potassium content of all the soils by the four methods used, which had as extractants 0.024N HAc, IN NH 4 Ac, 0.IN HN0 3 and boiling IN HN0 3 . The British Columbia and Ontario soils used (which responded to potassium) had the lowest potassium content. The potassium levels in most of the soils with values less than 50 lb./ac. in the Aa horizon increased with increase in depth of profile. No correlation occurred between the 10-11 A peaks of the clay fraction and exchangeable or hydrolyzable potassium content of the soils. Analyses of alfalfa grown in the greenhouse on the Thin Black Solod, Camrose and Wetaskiwin revealed that the plants had below the critical 1 per cent potassium content on the check plots while the Winterburn soil had 1.72 per cent. Plants from the check plots of field experiments on soils testing less than 50 lb./ac. of K (HAc method) had greater than 1 per cent but below 1.5 per cent. However, responses were not obtained from potassium application on grass-legume stands on these soils during the summers of 1963 and 1964. Moisture conditions were adverse and yields were low in all plots, consequently more testing is required. It would appear that the Alberta soils with soil test values less than 50 lb./ac. of K (HAc) should be rated low in potassium content. This suggests the probability of an inadequate potassium supply especially for crops with high potassium requirements.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Study of Soil Potassium Field observations show that a large number of our soils con tain sufficient soluble potassium to produce maximum yields of grass. This appears to be true whether the potassium is in its natural condition or whether it is affected by salts which have a tendency to increase its solubility.
