Аннотация: The broadleaves of Britain form part of that vast natural forest of northern Europe which once streched from the Atlantic to the Steppes of Russia. Formerly important as sources of building material and fuel, their main contribution nowadays is as shade-and shelter-providers although some-oak, ash, sycamore and lime - are still used by furniture-makers and willow remains thr traditional material for cricket bats.

Аннотация: The experimental material was put out as 2+ 1 plants in the spring of 1954. In October 1956, four plants in each plot were inoculated with snow blight, and the remaing plants sprayed with a 3% solution of lime-sulphur to protect them from attack. The inoculated plants were all attacked by the fungus, and during the following winter constituted natural seats of infection; Details can be seen in table 1 and figs. 1 and 2

Аннотация: A study has been made of the effects of different methods of fertilizing spruce plants (Picea abies (L.) Karst.) in the nursery before planting them on Calluna heath land in S.W. Sweden. It was found that the use of superphosphate led to strongly stimulated development of the plants after planting. The same was also the case after fertilizing with NPK, while the use of only a similar amount of nitrogen or potassium as is contained in NPK did not have a positive effect. The growth of spruce was often further promoted if a dose of lime (5,000 kg/ha) was added in the nursery. Fertilization after planting was effective only if carried out after the plants had overcome the stunt period of juvenile development.

Аннотация: It is proposed that the long-term impact of lime on soil leads to drastic changes in the type of litter turnover and to a change in the humus form towards calcareous mull. The change towards mull is generally considered to increase the site's productivity. Limimg might have a restrictive influence on production in the short run whereas the long-term impact ia regarded to be the reserve.
