A Comparison of Methods to Determine Lime Requirement
Maintaining an optimal soil pH is crucial for maximizing crop yields and promoting overall soil health. The optimal soil pH is typically between 5.5 and 7.0 for most crops growing in Delaware. Maintaining an optimal soil pH ensures that essential nutrients are readily available for plant uptake and minimizes the potential for toxicity from elements like aluminum (Al) and manganese (Mn), which can become harmful in overly acidic conditions.
