Organic fertilizer is not just about improving soil! It hides the big trick of "supplementing carbon", which is essential for crops to not age prematurely and achieve high yields

When it comes to Organic Fertilizer, many people know that it can improve soil and help crop growth, but few are aware that it also has a "hidden skill" - replenishing "carbon", which is the most "powerful" aspect of organic fertilizer. To understand this' strength ', we need to start with the current soil conditions of farmland in our country.

Soil surveys in many agricultural districts and counties in our country show that after more than 40 years of "chemical agriculture" cultivation, the organic matter in the soil of large areas of farmland is almost depleted. The soil survey conducted by the national agricultural department in the past two years has been more intuitive: 4000-6000 soil samples were taken from each county, and the results showed that less than 5% had an organic matter content of 2% or more, 80% had an organic matter content of less than 1.5%, and nearly 15% of the soil samples had an organic matter content of even less than 1%.

In fact, the value of organic fertilizers in agriculture has long been recognized. It has the characteristics of "comprehensive nutrients and long-lasting fertilizer effect": it contains a large amount of essential trace elements for plants, as well as organic nutrients such as humic acid and vitamins. The application amount is flexible and the fertilizer effect is long-lasting, which not only increases crop yield in the current season, but also has an effect many years later; It can "improve soil physical and chemical properties, enhance soil fertility": it contains a large amount of organic matter (usually around 200g/kg), which is an important foundation of soil fertility. The humus in it can regulate soil acidity and alkalinity, improve fertilizer retention performance, and help form a good soil structure; It can also "promote soil microbial activity": provide nutrients and suitable environment for microorganisms, increase the number and population of beneficial microorganisms; At the same time, it can "maintain and promote soil nutrient balance": returning the nutrients absorbed by plants to the soil is also a good helper for "reducing fertilizer input costs" - using local materials, low costs, and improving fertilizer utilization efficiency while reducing fertilizer usage.

But these conventional advantages are not enough to highlight the "most powerful" aspects of organic fertilizers. Its true 'ace' is to supplement soil carbon elements!
You may not know that the carbon coefficient of organic matter is 1.724, which means there is 1 carbon in every 1.724 organic matter. The low organic matter content in the soil means that crops are unable to absorb water-soluble organic carbon from the soil, leading to carbon deficiency. The harm of soil carbon deficiency is far more serious than we imagine.
Firstly, the root system is weakened. Root growth requires both internal and external stimulation: the soil relies on its tendency towards water and fertilizer, and soils lacking organic matter have poor water content, making it difficult for fertilizer solutions to be "transported" to the roots, resulting in insufficient internal stimulation; Externally, relying on the interaction of soil microorganisms, insufficient organic matter can lead to a lack of carbon sources for microorganisms, sparse rhizosphere microbial communities, and weakened external stimuli. Without dual stimulation, crop roots will naturally weaken and age, which is the root cause of crop yield reduction and poor stress resistance.

Secondly, there is premature aging of crops. Root system weakness can directly lead to premature aging, and another easily overlooked reason is that substances such as lignin and cellulose in crops have low energy consumption when converted by the effective carbon absorbed by the roots. Even at night, on rainy days, or when there is insufficient CO ₂ in greenhouses, the conversion and accumulation can continue; If the roots cannot absorb effective carbon, they can only rely on photosynthesis in the leaves to convert CO ₂, and the same accumulation requires more energy consumption. When there is sufficient sunlight during the day, energy can still be supplied, but at night or on rainy days, crops can only consume their own energy. Long term energy balance imbalance can lead to premature aging of crops. This is particularly evident in melons, legumes, vegetables, and fruit trees that have a longer growth period.
In addition, carbon deficiency can also lead to crop yellowing and chlorosis. On rainy and overcast days, the use of sunlight has almost stopped, and crops are unable to absorb and convert CO ₂ in the air normally. Carbon nutrition and energy both decrease, and continuous rainy and overcast weather can cause yellow leaves and fallen leaves, and new leaves to lose their green color. This is not what people think of as "waterlogging", but rather a result of carbon deficiency.

The sub-health of crops is also closely related to carbon deficiency. Many crops have no obvious symptoms, but they shrink, grow slowly or become thin and weak, and even lose their original ecological aroma. This is often due to organic nutrient deficiency - that is, carbon deficiency. Although CO ₂ in the air is inexhaustible, crops continue to metabolize and consume energy even after photosynthesis stops at night. If there is a supplement of water-soluble organic carbon absorbed by the roots, material conversion, accumulation, and energy supply can proceed normally; Once there is a carbon deficiency, crops will be overdrawn day and night, falling into a "sub healthy" state. More seriously, carbon deficiency can weaken the disease resistance of crops: when crops cope with pests and diseases, they need to release "pheromones" to drive away the source of the disease, and after damage, they also need "repair substances" to repair it, all of which contain carbon. Organic nutrients are insufficient, and these substances cannot be fully generated. Weak plants are naturally more prone to illness than strong plants, so carbon deficiency is the "source of all diseases" in crops.
We have always emphasized that increasing the application of organic fertilizers is to improve soil and enhance organic matter, but often overlook its crucial role in replenishing carbon. It is precisely this overlooked role that determines the irreplaceable position of organic fertilizers in modern agriculture - supplementing soil carbon, injecting "vitality" into crops, making them stronger and more productive. This is the most powerful aspect of organic fertilizers!
