The study evaluates the potential of pine litter for use as a substrate in the propagation of vegetable transplants in trays. Sub-optimum pH and electrical conductivity of pine litter were addressed by incorporating 10 % feedlot manure by volume. The water holding capacities of pine litter and the pine litter-feedlot manure mixture were higher than the minimum required, but their air filled porosities were below optimum. The pine litter-feedlot manure mixture reduced the germination percentages of cabbage seedlings by 17 % and lettuce seedlings by 13 % relative to composted pine bark, but the germination percentage of tomato seedlings was similar in both substrates. There were no significant differences in the growth of vegetable transplants between the two substrates. In both substrates increasing nutrient availability by adding controlled-release fertilizer had similar positive effects on the growth transplants. Substrate-nutrient availability interactions were only observed in dry shoot mass of lettuce seedlings and dry root mass of tomato seedlings. Composting the pine-litter animal manure mixture could possibly improve the observed low germination percentage of vegetable transplants in pine litter.

International Radiocarbon Dating Conference, Lower Hutt City, Wellington, New Zealand, 18-25 October 1972 / A 7104 -year tree -ring chronology for bristlecone pine was published in tabular form in 1969. Since then, the chronology has been improved in quality and extended in time. Twenty-one pieces of wood, representing separate trees, have been identified for the period prior to 4000 B.C. and these have made possible a chronology extension to nearly 8200 years. In this paper, the specimens are described in terms of the time range each represents and their statistical parameters relating to the quality of tree-ring record they contain. These specimens not only have extended the climatic tree-ring chronology, but also have made possible the calendar-year dating of additional samples for calibration of the radiocarbon time scale.
