AGRICULTURAL IMPLEMENT FOR NO-TILL SEEDING

摘要

An agricultural implement includes a main body portion having leading edges (14) extending rearwardly and outwardly from a forward part of the main body portion. The main body portion includes an upper body portion (18a). At least the rear part of the upper surface of upper body portion (18a) is shaped to push soil generally upwardly and outwardly as the implement is moved through the soil. For example, the rear part of upper surface of upper body portion (18a) may be oriented generally obliquely. The implement furhter includes side body portions (20a) extending downwardly from the upper body portion. The side body portions (20a) preferably taper outwardly from the front to the back to also act to push the soil outwardly as the implement passes through the soil. As the implement passes through the soil, the leading edges (14) slice through the soil and the soil located above the upper surfaces (18a, 20a) is pushed upwardly and outwardly to thereby momentarily create a void in the soil. Seed supplied through seed supply means (34) is dropped into this void to allow for accurate placement of the seed in the soil. A press wheel (70) is positioned in a housing (74) located behind the implement to firmly press seeds into the soil to assist with germination. The implement is especially useful as a seeder. The implement may further include fertilizer delivery means (36) and delivery tubes (80, 82) for delivering other beneficial agents, such as herbicides and fungicides, to the soil.
