Fertilizers affect plant growth by replenishing plant nutrients, causing plants to grow faster and coarser. However, this only applies if the soil is deficient in nutrients. Fertilizers do not compensate for other growth inhibitors, such as lack of water, poor land preparation and weeds.

Fertilizers fall into two categories: man-made and natural. Artificial fertilizers release their nutrients within a few days to a few weeks, and some types are specially formulated to release more slowly over several months. Natural fertilizers may take months or years to release their nutrients. (Visible artificial fertilizer market demand is very high, if you want to build organic fertilizer production factory, you can contact us, we will provide you with professional programs and organic fertilizer production equipment)

Plant nutrients are divided into primary nutrients and secondary nutrients. Key nutrients include nitrogen, phosphorus and potassium, which are commonly found in fertilizers. Plants consume large amounts of essential nutrients as they grow. Secondary nutrients such as calcium, magnesium and sulphur are also heavily used by plants, but they are usually already present in the soil.

The most common cause of stunted plant growth is a lack of enough nitrogen in the soil. Different plants need different amounts, but too much nitrogen can produce bad results. Too much nitrogen, for example, can cause tomatoes to grow vines that don't produce much fruit.

Therefore, different fertilizers need to be used according to the growth conditions of different crops.
