Manure injection involves inserting manure directly into the soil rather than applying it on the surface. While this practice has several advantages, such as reducing odor and nitrogen loss, a notable disadvantage is that it can lead to increased wear on farming equipment. The injection process often requires specialized machinery designed for this function, and the added resistance and stress from working the equipment into the soil can contribute to faster degradation of components. This increased wear and tear may lead to more frequent maintenance or replacement costs for the equipment.

In contrast, the other options describe characteristics that are typically seen as advantages of manure injection. The speed of injection can make the process more efficient compared to surface application methods, the equipment requirements may be less extensive since it can sometimes use existing tools with modifications, and the reduced soil disturbance can be beneficial for soil health and structure. These points highlight the multifaceted considerations in the discussion of manure injection practices and their implications for nutrient management in agriculture.
