Chicken manure dried in the sun, and commercial organic fertilizer is similar? No way!
In a concentrated vegetable growing area research found that farmers with larger planting areas rarely apply organic fertilizer because of the labor costs. Farmers with smaller planting areas would choose to apply organic fertilizer. The application is basically sun-dried chicken manure, cow manure, a small number of people will choose to compost themselves.
Qualified commercial organic fertilizer is almost invisible, farmers believe that the price of commercial organic fertilizer is high. For the same amount of money, perhaps only 2-3 bags of commercial organic fertilizer can be applied, while traditional sun-dried chicken manure can be bought for nearly 2 square meters.
So, can sun-dried chicken manure really be almost as good as commercial organic fertilizer? Was it a waste of money to spend so much money to buy commercial organic fertilizer in the past?
The application of unrotted chicken manure is not only harmful to the soil, but also increases the occurrence of soil pests, and does not reduce the role of agricultural surface pollution prevention, but will increase agricultural ammonia nitrogen emissions.
In recent years, due to the traditional nitrogen, phosphorus, potassium fertilizer competition intensified, organic fertilizer profits are better, more and more companies began to enter the organic fertilizer industry, of course, there is also the role of government promotion. For example, the soil organic matter to improve the project, organic fertilizer instead of chemical fertilizer, fertilizer zero growth action, etc., are for the market to promote organic fertilizer to play a leading role.
In many regions, some so-called bidding projects to organic fertilizer prices are very low, I really do not know if these organic fertilizers can play a role.
The cost of organic fertilizer depends on the source of raw materials, some enterprises raw materials may be purchased at high prices for processing of organic fertilizers in the food industry, some enterprises may be the use of certain industrial waste organic materials to produce organic fertilizers, and some enterprises may use the environmental protection enterprises of environmental protection treatment to get the organic material. This leads to a very large difference in the cost of organic fertilizer production.
The quality of organic fertilizer is also worlds apart. Good organic fertilizer can condition the soil biologically, physically and chemically, stabilize crop yields, improve crop quality, improve soil fertility, etc.
Substandard organic fertilizer, or organic fertilizer made from certain waste materials, is really cheap, but it may also pollute the farmland and make the soil lose its proper productivity, or produce agricultural products with safety hazards.
The research found that many farmers themselves know that their own land becomes slaty, land acidification, soil-borne diseases are becoming more and more serious, know that the application of organic fertilizer is helpful, but considering the problem of labor, or the misunderstanding of the existence of commercial organic fertilizer, either do not use organic fertilizer, or use the always applied sun-dried chicken manure.
For farmers who work hard to farm, it is considerable to save 10 dollars. As a result, counterfeit and shoddy fertilizers are rampant in many agricultural growing areas.
From the current point of view, because of years of application of chemical fertilizers, farmers also know that it is not good for the soil, but how to promote some fully rotted, raw materials from safe sources, nutrient content of the standard, the price can be accepted organic fertilizers, is the key.
For those on the market tender procurement of 300-400 yuan of organic fertilizer, excluding freight and reasonable profit, their organic fertilizer is made of what? I'm afraid with straw is not made, once these very cheap organic fertilizer is accepted by the market, those qualified organic fertilizer can still be applied to the soil?
Now we know that the soil fertility is declining, the state to give money, give people to vigorously improve the application rate of organic fertilizer. But once the market is flooded with these unqualified, or can not be called organic fertilizer organic waste occupation, the future of organic fertilizer to replace chemical fertilizers is not the hard part, but qualified organic fertilizer to replace poor quality organic fertilizer is the hard part!
So: do not wait until the soil is bad, only to wake up! Although chicken manure is good, it must be properly fermented before it can be used. If the sun-dried chicken manure, directly as a commercial organic fertilizer, it would be a big mistake!
