In agricultural practice, the choice of fertilizer directly affects the growth and yield of crops. Sulphur-containing fertilizers, which provide valuable sulphur for many crops, are not suitable for all crops.
First of all, be especially careful with crops with acidic soils such as strawberries and cranberries. Because they already grow well in acidic soils, sulfur-containing fertilizers can further reduce the pH of the soil, which can adversely affect their growth.
Second, some crops with high calcium absorption, such as sugar beets and kale, have a high calcium requirement. However, the sulfur element in sulfur-containing fertilizers combines with calcium in the soil to form calcium sulfate, which is not easily absorbed by crops, thus reducing the amount of calcium available in the soil. This is detrimental to the growth of crops with high calcium requirements.
In addition, some sulfur-sensitive crops, such as beans and potatoes, also require special attention. Excessive sulphur may cause the growth of these crops to be stunted, and the leaves may show symptoms such as yellowing, spots, and even cause some diseases.
In addition, some crops that need to absorb a lot of sulfur, such as garlic and onions, if excessive application of sulfur-containing fertilizers may lead to stunted crop growth, yellowing of leaves, wilting, etc., which not only affects the yield, but also may affect its quality.
In addition, it is also necessary to pay attention to the compatibility of sulfur-containing fertilizers with other fertilizers or pesticides. For example, mixing sulfur-containing fertilizers with copper-containing preparations may cause precipitation and reduce the effectiveness of the fertilizer;Mixing with organic fertilizer may improve the fertilizer efficiency of organic fertilizer.
Therefore, when using fertilizers, we need to reasonably control the amount of sulfur according to the growth characteristics and requirements of different crops. Avoid over-application of sulphur-containing fertilizers that negatively affect the growth of crops. At the same time, it is also necessary to pay attention to the use of other fertilizers or pesticides to avoid interactions or adverse reactions. It is best to use fertilizer under the guidance of a professional.
