What types of foliar fertilizers are there? A detailed explanation of spraying precautions
Foliar fertilizer is a type of fertilizer in which nutrients are applied to the leaf surface of crops and perform their basic functions through absorption by the leaves. Plant leaves have two layers of epidermis, the upper and lower, composed of epidermal cells. On the outer side of the upper epidermal cells there is a cuticle and wax, which can protect the mesophyll cells beneath the epidermal tissue in carrying out photosynthesis, respir...

Foliar fertilizer is not the same as pesticide; the difference between the two must be clearly distinguished
I. Why are medium-element water-soluble fertilizers used for fertilizing fruit trees? 1. The soil is not lacking in calcium fertilizer; what is lacking is mobile ionic calcium, so when choosing fertilizer, be sure to choose a calcium fertilizer that dissolves quickly in water. Research shows that crops such as ginger, watermelon, chili pepper, eggplant, tomato, and grape absorb calcium far...

Fertilizer is not a case of the more the better; rational fertilization is more important
In a broad sense, China has a history of more than 10 years of slow and controlled release fertilizer production. However, among those currently promoted and applied with relative success are only the urease inhibitor stabilized nitrogen fertilizer from the Shenyang Institute of Applied Ecology, Chinese Academy of Sciences, the fertilizer-coated fertilizer type slow release fertilizer using a patent from the School of Engineering of Zhengzhou University, the slow release rice fertilizer from the Soil and Fertilizer Institute of the Guangdong Academy of Agricultural Sciences, and Shanghai Han...

Characteristics and Application Methods of Water-Soluble Fertilizers Explained in Detail
The "7 major issues" to watch out for when applying foliar fertilizers: Issue one, the spraying concentration must be appropriate. The spraying concentration of foliar fertilizer directly affects the result; if too high, it easily burns crop leaves; if too low, it not only increases the workload but also fails to achieve the spraying effect, so during spraying it must be based on the crop...

What is the difference between fast-dissolving, fast-spreading fertilizers and slow-dissolving, slow-spreading fertilizers?
At present, China has a great many types of controlled-release and slow-release fertilizers, and products with various materials and release mechanisms can be said to be flourishing in a hundred flowers. However, because farmers have a low level of knowledge, they are seriously lacking in understanding of such upgraded products. In particular, some unscrupulous manufacturers hype concepts and cut corners, which hurts consumers' feelings and causes them to...

Which fertilizers are unsuitable as seed fertilizers? Understand before applying fertilizer
Three types of chemical fertilizers are unsuitable as seed fertilizers. Fertilizers containing harmful ions: ammonium chloride and potassium chloride fertilizers contain large amounts of harmful chloride ions. After being applied to the soil, they produce water-soluble compounds that burn seeds and seedlings; fertilizers such as ammonium nitrate and potassium nitrate contain nitrate ions, which seriously affect seed germination, so they are unsuitable as seed fertilizers....
