<p>There is proposed a novel furrow opening apparatus (10) for consecutively fertilising and sowing. The apparatus (10) includes a first furrow opener (12) adapted to create a first furrow (158) and a second furrow opener (14) adapted to partially fill the first furrow (158) and create a second furrow (168). Wherein the second furrow (168) is shallower than the first furrow (158). Preferably, fertiliser is deposited into the first furrow (158) and covered by soil by the action of the second furrow opener (14). Seed is then deposited into the second furrow (168) and covered with soil by a press wheel (130). In this way the seed is separated from the fertiliser by a layer of soil. This prevents the germinating seed being adversely affected by high concentration of fertiliser in close proximity to the seed.</p> |
