Options for incorporation of manure in the soil. Injector knives with sweeps that run four to six inches below the soil surface allow manure placement in a wider band at a shallower depth. Location of the manure higher in the profile minimizes potential leaching and reduces power requirements. Sweeps can be used to apply a higher rate of manure than a conventional injector knife. These systems are most commonly used for pre-plant application of manure.
Manure is applied near the tillage tool that immediately mixes the manure into the soil.
Speed of application, low power requirements, and uniform mixing of soil and manure have contributed to the growing popularity of this approach. In addition, such systems are being used to side-dress manure on row crops without foliage damage. Side-dressing expands the season during which manure can be applied and improves the use of manure nutrients. All soil incorporation systems also offer the advantage of ammonia conservation and minimal odors. Irrigation Various irrigation systems can apply diluted manure from swine and dairy lagoons and runoff from outdoor livestock lots.
