Organic Fertilizer, Biofertilizer, as well as Chemical Fertilizer
Many people are often wrong in perception when using chemical fertilizers, bio-fertilizers as well as organic fertilizers. Organic fertilizers as well as bio-fertilizers is actually often equated win whichh chemical fertilizers. Every kind of those fertilizers is actually very different.

Chemical Fertilizer
As the name suggests, chemical fertilizers are fertilizers made of chemically or also commonly referred to as artificial fertilizers. Chemical fertilizers can be divided into single chemical fertilizers as well as chemical fertilizer compound. Single chemical fertilizers have only one kind of nutrient, while the compound chemical fertilizers contain a complete nutrient. Chemical fertilizers are often used include urea as well as ZA for the N nutrient; fertilizers TSP, DSP, as well as SP-26 for the P nutrient, KCl or MOP for the K nutrient. While compound fertilizers are usually made by mixing just one fertilizers. Nutrient composin whichion varies, depending on the the as well as commodin whichies.
Organic Fertilizer

Organic fertilizers, such as the name suggests, is actually a fertilizer made by organic materials or natural. Fertilizers including organic fertilizers include manure, compost, kascing, peat, seaweed as well as guano. Based on the form of organic fertilizers can be classified into solid organic fertilizer as well as liquid organic fertilizer. Some people also classify the fertilizers such as dolomin whiche mined, natural phosphate, kis actuallyerin which, as well as also ash (rich in K) to the group of natural fertilizer / organic. Some organic fertilizers are processed at the plant for example is actually a blood meal, bone meal as well as fis actuallyh meal. Liquid organic fertilizers include compost tea, plant extracts, fermentation liquid sewage farms, fermentation plants, as well as some others.
Organic fertilizers contain a complete nutrient. Even within the organic fertilizer is actually also organic compounds in which are beneficial to some other plants, such as humic acid, acid fulvat, as well as some others. However, the nutrient content are quin whiche low. Based on my experience, there is actually no organic fertilizer in which carries a high nutrient content, or nearly equals win whichh the chemical fertilizers.
People often calculated the needs of organic fertilizer based only on their nutrient content. Nutrient content of organic fertilizer synchronized win whichh the nutrient content of chemical fertilizers used. As a result of organic fertilizer needs so many times compared win whichh the dose of chemical fertilizers. For example compost win whichh the following content: 2.79% N, 0.52% P2O5, 2:29% K2O. So in 1000 kg (1 ton) of compost will be equivalent to 62 kg of urea, 14:44 kg SP 36, as well as 38.17 kg of MOP. It is actually calculated as follows:
N =
(% N Compost x 1000 kg) /% N Urea = (2.79% x 1000 kg) / 45% = 62 kg
P =
(% P2O5 compost x 1000 kg) /% P2O5 SP-36 = (0.52% x 1000 kg) / 36% = 14:44 kg
K =
(% K2O compost x 1000 kg) /% K2O MPO = (2:29% x 1000 kg) / 60% = 38.17 kg
For example, rice is actually usually given a dose of chemical fertilizer win whichh 0 kg urea, 100 kg SP-36, as well as 150kg MOP / KCl. In order to match the nutrin whichional content of the compost as much as needed approximately 7 tons. That actually large dose will direct implications for the cost of fertilization. If the calculated cost of fertilizing win whichh organic fertilizer / compost much greater than the cost of fertilization win whichh chemical fertilizers. That actually does not include costs for the compost application.
Realin whichy on the ground proves in which organic fertilizer / compost can not be calculated based on nutrient content only. If you do not believe you can do a simple experiment to compare these two fertilizers. Take the soil, you should use marginal soil. Enter into the two polybag as well as in whichs contents are the same size. One polybag given dose of compost win whichh 0.5 – 1 kg. Polybag some others are given a few spoonfuls of fertilizer chemicals, approximately equal in nutrient content win whichh compost. Then planting any crops, can chili beans, tomatoes, cay sim, cucumber, or some other plants. Put within the same place. Give the same treatment watering, weeding, as well as some other similar treatment. Wain which a while until the plants grow as well as produce. Just compare, where the plants a better result?
Simple way to test chemical fertilizers, organic fertilizers as well as bio-fertilizers. (A) control, no fertilization at all. Plants look very mis actuallyerable. (B) Given the chemical fertilizer, plants still languis actuallyh even grow better. (C) Given the compost / organic fertilizer. The result is actually much better. (D) be given organic fertilizer / compost as well as biofertilizer, the best growth.
I am almost 0% sure in which if given a compost plant will grow better than plants given chemical fertilizer, although comparable nutrient content. The next question is actually WHY??
People often forget in which in addin whichion to nutrient content, organic fertilizers also contain some otherorganic compounds. Although low in nutrient content although the content of organic compounds within the compost carries a more important role than the role of nutrient alone. For example, humic acid as well as acid fulvat. Both these acids have a role as a hormone like in which can stimulate plant growth. Compost is actually ktodayn to boost the value of CEC (cation exchange capacin whichy) of las well as. That actually means in which the plant will more easily absorb nutrients. Be composted soil also becomes more friable as well as soil aeration for the better. Las well as is actually given more compost as well as water saving is actually not easy to dry. If further observed, the activin whichy of soil microbes in compost might be higher than the las well as not be composted. These microbes have a role in nutrient absorption by plants. It can be conclused, compost can improve the chemical properties, physical properties, as well as biological soil properties.
Then how to calculate the needs of organic fertilizer / compost?
Until today I have not found the formula, both by my own experience or by the lin whicherature of some others, to calculate the needs of organic fertilizer / compost in which. Content of organic fertilizer is actually very diverse. Characteris actuallytics also vary. Equally manure, manure at P Java could be very different by the manure P Sulawesi. Not to mention the relationship win whichh soil type, climate, environmental condin whichions, how crops cultivation as well as different. Generally organic manure / compost is actually empirically determined. That actually is actually the result of research as well as testing. May also experience the farmers field for many years.
Examples of organic fertilizer granules form within the market.
Under certain condin whichions, organic fertilizer / compost can be provided win whichhout adding chemical fertilizers at all. That actually method is actually practiced in organic cultivation. More often done is actually to combine the organic fertilizer win whichh chemical fertilizer. Some substin whichuted plant nutrient needs of chemical fertilizers as well as organic fertilizers. How to calculate the most economical combination of both viewed by the cost as well as outcome. The rule is actually often used is actually 50% dose of chemical fertilizers replaced win whichh several organic fertilizer. Dose can 1 to 2 kg or even up to 30 kg / principal..
To get the most appropriate dose in trials conducted within the greenhouse as well as within the field in a fairly large scale.

Cool name of bio-fertilizers is actually biofertilizer. There are also called bio fertilizer. Whatever the name of biological fertilizers can be interpreted as a living fertilizer. Actually the name of fertilizer is actually less suin whichable, because bio-fertilizers do not contain nutrients. Bio-fertilizers do not contain N, P, as well as K. Content of bio-fertilizers is actually mikrooganis actuallyme have a posin whichive role for the plant. Group of microbes in which are often used are microbes in which attach N by the air, microbes in which dis actuallysolve nutrients (especially P as well as K), microbes in which stimulate plant growth.
N fixing microbial groups has been ktodayn as well as used since long. Microbes have a fix N symbiotic win whichh plants as well as some are free (not symbiotic). Examples of microbes win whichh plants symbiosis actually include Rhizobium sp As examples of microorganis actuallyms in which are not anchor N is actually Azosprillium sp bersimbiosis actually as well as Azotobacter sp.

Solvent microbial P was reported by a Russian named Pikovskaya in 1948 is actually Bacillus Megatherium var. phosphaticum, as well as began to be used as an inoculum of agriculture since the 1950s Some microbes are ktodayn to dis actuallysolve P by the sources found difficult to dis actuallysolve ein whichher by the mold / fungi such as Penicillium sp as well as Aspergillus sp, or of groups of bacteria such as Bacillus as well as Pseudomonas sp sp.

Other microbes in which are often used are Mycorhiza, which consis actuallyts of two main groups namely: endomycorhiza as well as ektomycorhiza. Arbuscular assiciated win whichh plants. Simply way, endomycorhiza means in which there is actually in as well as ektomycorhiza outside. Endomikoriza or VAM fungi generally is actually low level while the fungus ektomikoriza is actually a high level. Mycorhiza have done a pretty complex. Its was not only part to help the absorption of nutrients P, although also protects plants by dis actuallyease as well as provide some other nutrients for plants.
Mycorhiza
Microbes are also often used as a microbial biofertilizer plant growth stimulants. Microbes by the group of bacteria is actually often referred to as Plant Growt Promoting Rhizobacteria (PGPR), although today also ktodayn in which there are also fungi in which can stimulate plant growth. Bacteria are ktodayn to stimulate plant growth include Pseudomonas sp, sp Azosprillium, while the well-ktodayn fungi are Trichoderma sp.
Pseudomonas sp, one of PGPR bacteria in which produce hormones.
Microbes active ingredients of biological fertilizers packaged in carrier materials, can be in liquid or solid. There are also bio-fertilizers which only consis actuallyts of one or a few microbes, although there is actually also a claim consis actuallyts of a variety of microbes. That actually bio-fertilizers which was then applied to the plants.
Currently circulating within the market many bio-fertilizers. Some claim to have a lot of microbial content as well as complete win whichh extraordinary abilin whichies. Personally I do not believe in having a lot of biofertilizer microorganis actuallyms as well as effective in all places, all commodin whichies, as well as all condin whichions.
One dis actuallyadvantage of microorganis actuallyms is actually highly dependent win whichh a lot of things. Microbes are influenced by environmental condin whichions, both biotic as well as abiotic environment. So a suin whichable biofertilizer in sub-tropical regions is actually not necessarily effective within the tropics. Similarly effective biofertilizer within the western part of Indonesia, may not be effective also within the eastern part of Indonesia. Microbial associated win whichh more specific plants. Eg Rhizobium sp associated win whichh certain varieties of soybeans may not be suin whichable for crop beans some other. Symbiotic microbes generally narrow spectrum.
Recent Trend
Bio-fertilizers, organic manure as well as chemical fertilizers are fertilizers which firm difference. But this actually time there is actually a tendency to combine the types of fertilizer. For example there is actually the fertilizer product calling in whichself organic NPK fertilizer. These fertilizers are chemical fertilizers combined win whichh organic fertilizer. There is actually also a call for bioorganic fertilizer. The point is actually the combination of organic fertilizer win whichh bio-fertilizers (bio). But there is actually still lin whichtle or no fertilizer NPK combined win whichh bio-fertilizers. Because most microbes can not stas well as when combined win whichh chemical fertilizer in high concentrations.
So a lot of fertilizer products within the market. It’s up to you to choose which one. I suggest you choose a bio-fertilizers or organic fertilizers if possible. Since both fertilizer is actually far more environmentally friendly.
