The role of vermiculite in the fixation of potassium in soils and the availability of potassium for vine nutrition in some Niagara vineyards

The Niagara P e n i n s u l a Supports a f l o u r i s h i n g grape and wine i n d u s t r y , where much of the potassium f e r t i l i z e r a p p l i e d to the vineyard s o i l s may not show up in the f r u i t or vines but is fixed by the clay m i n e r a l s in the s o i l . Soil samples were c o l l e c t e d on a n o r t h - s o u t h l i ne through a high d e n s i t y of v i n e y a r d s and examined by x - r a y d i f f r a c t i o n to determine the r e l a t i o n s h i p of potassium with r e s p e c t to c l a y minerals p r e s e n t . The i n v e s t i g a t i o n shows the p h y l l o s i l i c a t e m i n e r a l s present t o be i l l i t e , c h l o r i t e and v e r m i c u l i t e . The v e r m i c u l i t e p r e s e n t is not t h e usual M g - v e r m i c u l i t e , but a K - v e r m i c u l i t e which can be c o n s i d e r e d as a degraded i l l i t e - - t h a t i s , an i l l i t e which has l o s t potassium i o n s . The r e s u l t i n g K - d e f i c i e n t mineral possesses a very l i m i t e d expansion l a t t i ce and is capable of c a p t u r i n g potassium ions and c o n v e r t i n g back t o the i l l i t e form.

Biotransformation of aromatic hydrocarbons and organic sulphides by fungi

Toluene is converted to benzyl alcohol by the fungi Mortierella isabellina and Helminthosporium species; in the latter case, the product is further metabolized. Toluene-a -d 1 , toluene-a,a-d2, and toluene-a,a,a-d 3 have been used with Mortierellaisabellina in a series of experiments to determine both primary and secondary deuterium kinetic isotope effects for the enzymic benzylic hydroxylation reaction. The values obtained, intermolecular primary kH/kD = intramolecular p rim a r y kH r kD = 1. 0 2 + O. 0 5, and sec 0 n dar y k H I kD = 1. 37 .:!. 0.05, suggest a mechanism for the reaction involving benzylic proton removal from a radical intermediate in a non-symmetrical transition state. 2H NMR (30.7 MHz) studies using ethylbenzene-l,1-d 2 , 3 -fluoroethylbenzene-l,1-d 2 , 4 -fluoroethylbenzene-l,1-d 2 , and toluene-dB as substrates with Mortierella isabellina suggest, based on the observable differences in rates of conversion between the substrates, that the hydroxylation of hydrocarbons at the benzylic position proceeds via a one electron abstraction from the aromatic ring, giving a radical cation. A series of 1,3-oxathiolanes (eight) were incubated with Mortierella isabellina , Helminthosporium , Rhizopus arrhizus , and Aspergillus niger . Sulphoxides were obtained from Mortierella isabellina and Rhizopus arrhizus using the substrates 2-phenyl-, 2-methyl-2-phenyl-, and 2-phenyl-2-tert. butyl-l,3-oxathiolane. The relative stereochemistry of 2-methyl-2-phenyl-l,3-oxathiolan-l-oxide was assigned based on lH decoupling, n.O.e, 1 and H NMR experiments. The lH NMR (200 MHz) of the methylene protons of 2-methyl-2-phenyl-l,3-oxathiolan-l-oxide was used as a diagnostic standard in assigning the relative stereochemistry of 2-phenyl-l,3-oxathiolan-l-oxide and 2-phenyl-2-tert. butyl-l,3-oxathiolan-l-oxide. The sulphoxides obtained were consistent with an oxidation occurring from the opposite side of the molecule to the phenyl substituent.

A. S. Whiting Manufacturing Company Limited, minute book, 1872-1909.

The Cedar Dale Scythe Works was the second manufacturing company that A.S. Whiting had established in Oshawa, the first being the Oshawa Manufacturing Co. in 1852. The Oshawa Manufacturing Co. was eventually taken over by the Joseph Hall Works in 1857. In 1862, the Cedar Dale Works was built after being in a rented space in the Hall Works for two years, building scythes and hoes. With the building of the firm, the village of Cedar Dale was established. In 1867, the firm became Whiting and Cowan when John Cowan bought into the company. After the death of Whiting in 1867, his son-in-law, R.S. Hamlin headed the company. By 1872, it became the A.S. Whiting Manufacturing Co. when Cowan withdrew from the business. Before Whiting’s death, the company had been profitable but due to new machinery being developed, hand tools were becoming obsolete and the business only lasted for a few more years (source: Oshawa Community Museum and Archives Web site).
