The line intersection method is described. In practical tests with plants, including beans, the method compared well with direct measurement.-Duke Uni...

The roots are laid on a flat surface and the number of intersections between the roots and random straight lines are counted. Total root length is the...

Phosphorus inputs and losses are calculated for contrasting farming systems: cereals were a major product in all systems. In typical modern British wh...

The mathematical models of Gardner (1960) and Cowan (1965) are developed to show that the soil matric potential at which rhizosphere resistance become...

Data are presented for a range of species including perennial grasses, white clover, lucerne, cereals and soyabeans on the length of roots per unit ar...

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...

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...

Experimental evidence claiming to show appreciable rhizosphere resistances in soils much wetter than permanent wilting point (sometimes even at soil m...

Results of some experiments on a range of species, including maize, castor and sunflowers, did not appear to be in accordance with the claim that appr...

In this technique the roots are laid out on a flat surface and a count is made of the number of intersections between the roots and random straight li...
