Mature Lolium perenne plants grown in pots of P deficient soil were subjected to gradually increasing drought, and uptake of P was determined during a...Read more
A perennial Festuca pratensis ley was grown during 3 years in a field experiment at Kjettslinge, Sweden. N uptake, defined as the flow of N into the c...Read more
Natural populations of Trifolium repens collected from contrasting soil types differed in response to Ca, Mg and K when grown in sand culture. Populat...Read more
A technique is described for measuring the time-course of uptake of 32P from soil. Carrier-free 32P was applied to the soil of potted Lolium perenne c...Read more
Concentration gradients of phosphate, K, Ca and Mg were measured near a plane of onion seedling roots at a range of soil water contents, in a special ...Read more
Bioassay based on the uptake of 32P from 5 X 10-6 M phosphate solution during a 15 min period was tested on birch (Betula verrucosa Ehrh.) and sycamor...Read more
In trials in flowing solution culture, the growth rate of Anthoxanthum odoratum was similar over the entire range of K concentrations tested (0.1-3.3 ...Read more
At higher soil water contents, chloride uptake by onion roots was greater, and the zones of depletion extended further. Models of ion transport were d...Read more
Measurements were made to determine the balance between photosynthesis, animal intake and the losses of matter in swards maintained by 'lenient' conti...Read more
