Pot Method for Soil Cultures

Soil Conditioner, Chemical Effects of Soil Conditioner upon Plant Composition and Uptake

“…The seven silt loams had been cropped four times in a green house experiment. Six of them had pH values of 5.1 to 5.5, but the limestoned soils showed pH values of near 6 at harvest time, against pH 7 for the Dickson soil. The upper Maury soil and the Maury soil third in Tables VI and VII had phosphorus pentoxide contents of 5.08 and 0.55%, respectively, and corresponding fluorine contents of 3344 and 260 p.p.m.…”

“…The bulk of soil was processed and potted as previously described (7). Half of it was limestoned at the rate of 2 tons per 2,000,000 pounds of soil to impart a final pH value of 6.5.…”

“…In studying nutritional factors which are accumulated or stored, it would be desirable to start the animal on the nutritional regime immediately after birth. Early attempts by other workers to raise baby pigs taken at birth were unsuccessful (7,10), and colostrum was considered essential for survival.…”

Variability in Results from Greenhouse Pot Experiments Comparing Phosphorus Rates and Sources1

“…Pot exPeriments at Knoxville-These tests ( 4) were conducted in a greenhouse 30 by 60 feet in size oriented in an east-west direction. The greenhouse was equipped with slat shades which were used to reduce heat during hot summer days.…”
