The herbicide hexazinone was applied as the commercial formulation Velpar L at field-rate (FR) concentrations of FR (14.77 microg ai g(-1)), FRx5 (73.85 microg ai g(-1)), FRx10 (147.70 microg ai g(-1)), FRx50 (738.50 microg ai g(-1)), and FRx100 (1477.00 microg ai g(-1)) to acidic soil, pH 4.12, taken from a lowbush blueberry field. Hexazinone was tested for inhibitory effects on various transformations of the nitrogen cycle and soil respiration. Nitrogen fixation was unaffected by hexazinone levels up to FRx100 following a 4-week incubation period. Ammonification was initially inhibited by all levels of hexazinone, but after 4 weeks, ammonification in all treatment systems was equal to or greater than the control. Nitrification was more sensitive to hexazinone; however, application at a field-rate level caused no inhibition. Inhibitory effects were noted above FR after a 2-month endpoint analysis and above FRx5 after a 6-month endpoint analysis. Hexazinone concentrations up to and including FRx100 stimulated denitrification. Soil respiration was also stimulated over a 3-week period when applied at a level up to 100 times the recommended field rate. In general, it was found that when applied at the recommended field application rate, hexazinone does not adversely affect the nitrogen cycle or soil respiration in acidic lowbush blueberry soils.
THE apple is the first in importance of all fruits. It will thrive on nearly any well drained soil. Its period of ripening, unlike other fruits, extends nearly through the whole season. By mak¬ ing careful selection, a constant succession can be obtained. For family use there is no fruit that is more indispensable. No fruit is so healthful and many physicians say that if a person would eat an apple a day they could dispense with doctor bills. Besides this, and just as important, is the fact that the average price on the market is steadily increasing and the immense demand for home consumption, foreign shipping, canning and evaporating assures high prices. The apple if given the same care and attention as other farm crops, will yield greater returns per acre. The fol¬ lowing list we consider to be the best for general planting. Early Summer Varieties DUCHESS OF OLDENBURG-Season, July and August. Tree upright, vigorous and extremely hardy. An early and annual bearer of uni¬ formly large crops. Fruit large, greenish yel¬ low, with red stripes. Flesh light yellow, medi¬ um fine grain, firm; flavor a pleasant acid; a great cooking and fine market sort. EARLY HARVEST-Size, medium, roundish, usu¬ ally more or less oblate, smooth, bright straw color when ripe; flesh nearly white, flavor rather acid, fine. Season July. Produc¬ tive. Needs rich cultivation to be fine. Good throughout the Northern states and Southwest.
By mail postpaid 1 year 3 to 4 feet. By Express or Freight First class 2 year 5 to 7 feet tall_ Medium 2 year 4 to 5 feet tall_ A PPLE is the King of all Fruits. It always sells well on the market. Who doesn't like to sit down on a winter night and eat a few of those luscious apples? Doctors always advise the use of Apples for health, both for adults and the chil¬ dren. We have selected our varieties from a large list and believe we have the best suited to all sections that can be gotten together in the room we have to give to this Fruit. Our Apple Trees are grown by us here in the North and will bear quicker than Western or Southern grown Apple Trees. Plant our Lake Shore Grown Apple Trees.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
