Phosphorus is one of the nutrients most frequently limiting crop yields on tropical acid soils. Strategies to improve agricultural production on these soils include using adapted crop cultivars that efficiently exploit all available, applied and recy

Seven strains of tomato (Lycopersicon esculentum Mill.), with similar growth rates under adequate P availability, differed in dry matter accumulation by up to 73% when grown under P deficiency in a sand-alumina medium. The rate of P uptake per unit o

Neutron-scattering measurements have been made at 10 $K$ of phonons in a copper crystal neutron-irradiated at 4 $K$. The results, though clearly showing $q$-dependent defect-phonon perturbation effects, could not be explained entirely by simplified c

An experimental procedure employing resistivity measurements was used to observe the production of free interstitials and vacancies in platinum by atomic recoils produced from thermal neutron capture and fission neutron collision. For thermal neutron

The measurement of the stored energy of graphite taken from the lattice of the ORNL Graphite Reactor is described. The release of 26 cal/g of stored energy was observed upon heating to 218°C. The measurements were made using a new technique that dep

By relocating the fuel in the vicinity of a liquid helium cryostat located in the Oak Ridge Graphite Reactor it has been possible to separate the thermal and fast components of the reactor neutron flux. Studies of the radiation damage effects arising

Single crystals of copper were deformed at 4.2°K and 77.3°K. At 4.2°K, after a large strain produced by normal slip, jerky flow (discontinuous slip) occurs. From the study of reactor irradiated crystals, it was deduced that a packet of 30 slip lin

The effects of structural and chemical defects on the low‐temperature (30–50°K) annealing peak in low‐temperature reactor‐irradiated aluminum and copper were studied. From the fact that the density of reactor‐induced defects did not affect

Electrical resistivity measurements have been used to observe damage production rates for Cu, Nb, and Pt irradiated with high‐energy d‐Be neutrons at 4.2 °K. The neutrons were generated at the Oak Ridge Isochronous Cyclotron by the reaction of 4
