The difference between chelate and sulfate is in the type of compounds and their effect on plants. Chelated fertilizers are known as a type of nitrogen fertilizer. These fertilizers contain nitrogen, potassium and chlorine, and therefore they can be considered as a complete and balanced fertilizer. Chelates actually represent one of the types of nitrogenous compounds and are present in many natural sources. However, chelates are also produced industrially and usually ensure the improvement of plant growth if used correctly.
On the other hand, sulfate fertilizer is a type of phosphate fertilizer that contains nitrogen, phosphorus and sulfur. Sulfur is known as an important element to strengthen the soil structure and ensures improved plant growth. However, compared to chelates, sulfate fertilizers contain less potassium, and this means that these fertilizers alone are not considered as a complete and balanced fertilizer.
Important factors to choose the right fertilizer for plants
It should be noted that choosing the right fertilizer for plants is very important and it should be chosen according to the type of soil, plant needs and environmental conditions. Some plants need chelate fertilizers and others need sulfate fertilizers. For this reason, to choose the right fertilizer for plants, you must first identify the type of soil, pH and plant needs, and then choose the right fertilizer for them.
According to the difference between chelate and sulfate fertilizers, some plants may perform best with chelate fertilizers. For example, plants such as ornamental flowers, cucumbers, eggplants and strawberries need chelated fertilizers. Also, plants such as corn, potato and wheat may perform best with the use of chelated fertilizers.
Sulfate fertilizer can be used to deal with problems such as soil pH deviation towards alkalinity. Plants such as cabbage, broccoli, herbs and vegetables may need sulfate fertilizer.
