In the field of agricultural planting, the use of organic fertilizer and inorganic fertilizer has always been a hot topic of discussion, and many growers even insist on using only one of them. So, what is the difference between these two fertilizers? How to choose in actual use? The following will be analyzed in detail from six aspects.
- The production method is very different
Organic fertilizer is derived from the excrement or remains of organisms and is decomposed through fermentation. Manure from cattle, sheep and chickens, bean cake fertilizer, etc. are all included. Inorganic fertilizer is a product of chemical synthesis, including common nitrogen, phosphorus, potassium fertilizers and compound fertilizers.
- Nutrient content has its own advantages
Organic fertilizer has rich and diverse nutrients. Because it is a comprehensive product of fermentation and decomposition by microorganisms, its composition is complex. In addition to nitrogen, phosphorus and potassium, it is also rich in a variety of trace elements, which can provide crops with more comprehensive and balanced nutrition. Inorganic fertilizers are generally high-purity single compounds, or several compounds are mixed and processed in a specific proportion, such as nitrogen, phosphorus and potassium compound fertilizers, which have relatively simple ingredients.
- The difference in fertilizer performance is obvious
Organic fertilizer contains a large amount of organic matter, and its main function is to improve soil and fertilize soil. However, as a biological fermentation fertilizer, its component ratio is not as accurate as inorganic fertilizer, its water solubility is poor, and its fertilizer effect is slow, so it is generally not suitable for use as foliar fertilizer. Its role is to regulate the soil for a long time and fundamentally improve the growth environment of crops, just like Chinese medicine to treat both the symptoms and the root cause. Inorganic fertilizer has a fixed ratio of effective ingredients, good water solubility, rapid and efficient fertilizer effect, can directly act on the growth and development of crops, and can also be used as foliar fertilizer, what is lacking is supplemented, and it acts directly on the lesions.
- Different fertilization methods
Organic fertilizer is a slow-release fertilizer with a long fertilizer effect period, but it is released slowly, and the amount used each time is large. For example, farmyard manure often needs to be applied to the soil in tons, usually once or twice a year, to provide fertility for the soil for a long time. Inorganic fertilizers are purified and the amount used is relatively small. For example, water-soluble fertilizers can meet the needs of crops with about 5kg per mu of land. However, it is necessary to apply fertilizer several times according to the growth conditions of crops.
- Differences in ease of use
In the past, organic fertilizers were mostly homemade and needed to be fully decomposed, otherwise they would easily cause diseases and pests. However, there are now more and more finished organic fertilizers on the market, and they are also favored by many growers. Inorganic fertilizers are ready-to-use finished products that can be spread, sprayed, or flushed, and are easy to use.
- Different effects on soil
Organic fertilizers are rich in a large number of beneficial microorganisms, which can promote the biological transformation process in the soil and continuously improve soil fertility. However, long-term and large-scale application of inorganic fertilizers will inhibit the activity of soil microorganisms, resulting in a decrease in the automatic adjustment ability of the soil.
In summary, organic fertilizers are more suitable for use as base fertilizers and basal fertilizers, laying a good foundation for crop growth; inorganic fertilizers can replenish nutrients in a timely manner during daily topdressing, especially when crops show symptoms of nutrient deficiency. Both are indispensable. Only by using them in a reasonable combination can they jointly promote the healthy growth and development of plants and achieve high-quality and high-yield agriculture.
