Understanding the effects of spading uniformity and lime application to manage subsoil acidityThere are a range of machinery options that can provide different levels of lime incorporation such as spading. However, research to date on rotary spaders has shown soil/amendment mixing is not uniform due to the cyclical process, and the mixing quality reduces significantly at faster speed (Ucgul et al. 2019). This trial aimed to understand how the uniformity of soil-lime mixing by spading affected crop response and soil pH. |
