the T-Sem
How inverted T-slot works
The principle of the inverted T-slot is simple and effective, giving unmatched results in all situations – any surface, every soil type and all climatic conditions.
A set of discs at the front of the drill pre-slices an opening in which the T-SEM boot then passes to create the ideal seed-bed in bands.
The shoe sheds the vegetation and prunes the roots of the existing vegetation. The seed is placed on the firm base of the T-slot so that it is in good contact with the moisture rising by capillary action.
The horizontal slicing action of the wings of the shoe means that each side of the slot falls back after the tine has passed, but the chamber remains slightly open. The micro-environment thus created allows the light and moisture to enter but retains the warmth. The consistent placement of the seed in this mini-greenhouse gives optimum conditions for an even germination, and the tilth within permits rapid root development of the young seedlings.
The seed is squeezed into a narrow compacted slot with less tilth created. The disc or discs are prone to hairpin the dying trash into the slot so it is in contact with the seed. Thus the toxicity created by the decaying vegetation can inhibit establishment.
The slot made by a disc is not an ideal environment for either the germination or the root development of tender young seedlings.
VS
The shoe pushes aside all surface trash and prunes the roots of the existing sward when rejuvenating grassland. The chamber allows light and moisture to penetrate, but retains the warmth. Because the seed is surrounded by a fine tilth, root establishment is rapid.
