What are the types of fertilizers? Detailed explanation of the characteristics of each type

Advocates of special-purpose organic fertilizers say: organic fertilizers are less irritating to orchid plants, show no sign of fading color and variegation, and can reduce and prevent the occurrence of Bryllas disease. Habitual users of chemical fertilizers say: chemical fertilizers are made according to modern scientific methods, are the most scientifically grounded and the most ideal fertilizers. They believe that using organic fertilizers is an ancient method that does not fit the scientific age. Each side says it has reason, and each side says the other does not; the two views above inevitably each carry a tinge of being overly extreme! In fact, the components of organic fertilizers, in addition to containing the three major elements found in chemical fertilizers, also contain some plant nutrients that have not yet been analyzed out by scientific methods. Organic fertilizers do not have the immediate quick effect of chemical fertilizers, but they have the function of improving the soil. Chemical fertilizers take effect immediately, but continuous application easily makes the soil suffocate and harden. This is the general way of describing the two different views on organic fertilizers and chemical fertilizers! The author comes from a farming family and has personally experienced that what is said below is the absolutely true fact, namely: Vegetables grown exclusively with organic fertilizers have thick, plump leaves and thick, large stems and branches, tender and crisp, delicious and pleasing to people. Vegetables grown exclusively with chemical fertilizers have harder leaves and stems, a stiff, upright posture, and more fiber growing inside. Edible sugarcane grown exclusively with chemical fertilizers has hard stems and branches, concentrated sugar content, and is both sweet and sugary, liked by everyone. Sugarcane grown exclusively with organic fertilizers has thick, large, brittle stems and branches, but the sugar content is dilute and light, and the cane juice even has a salty feeling. From the facts above, it can be known that organic fertilizers and chemical fertilizers have different effects on crops. The components contained in the fertilizers truly differ, so their effects on orchid plants are of course also different, and both inevitably have their own advantages and disadvantages. Therefore, which is the ideal fertilizer for orchid plants is truly hard to determine. The purpose of fertilizing is to supply plants with abundant nutrition. And during cultivation, plants often show symptoms of malnutrition or nutritional imbalance. Especially for orchid plants grown in small pots using stones, bricks, or bark, the extension range of the root mass is particularly small. Cases of malnutrition or nutritional imbalance are also particularly numerous. Under circumstances where it is difficult to determine what state they are in and which type of nutrient they lack, the author believes that one should use as many kinds of fertilizers with different components as possible, that is, use organic fertilizers, chemical fertilizers, and other fertilizers of different natures in rotation, so as to prevent the deficiency of some component.
