Which of the following factors affects aglime quality?

Chemical purity is a vital factor that affects aglime quality because it determines the effectiveness of the limestone in neutralizing soil acidity. High-quality aglime typically contains a higher percentage of calcium carbonate or dolomitic lime, which directly contributes to its ability to raise soil pH and improve nutrient availability. Impurities or the presence of undesirable elements can diminish the lime’s performance, affecting crop yields and soil health.

While availability, color, and cost are considerations in the overall purchasing and application decisions for aglime, they do not directly influence how well the aglime performs in terms of soil amendment. Availability pertains to how accessible the aglime is for purchase and application, color may indicate some characteristics of the limestone but does not necessarily correlate with its chemical properties or effectiveness, and cost is primarily a budget factor rather than a quality determinant. Thus, when it comes to the specific quality of aglime, chemical purity stands out as the crucial aspect.
