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.
