The harm of incomplete fermentation of organic fertilizer to roses
If you want to understand the related knowledge of roses, the harm of incomplete fermentation of organic fertilizer to roses, the editor will introduce it next.
In the past two years, most people have increasingly discovered the disadvantages of using chemical fertilizers and have begun to slowly use organic fertilizers. Some people like to use dried chicken manure, sheep manure, cow dung, and all sorts of things like dog feces, pigeon droppings, and even directly burying fish offal bought at the market next to the flowers, using rice washing water, eggshells, and many other things as organic fertilizers for flowers. Many times, I really don't want to say anything because I am an advocate of (C-S) organic fertilizers. I say using these unfermented ones won't work, which makes some people feel disgusted. But to tell the truth, if you use unfermented organic fertilizers, you might as well not use them at all. The harm to ground planting is not obvious; for potted plants, the least you'll see is small black flies flying around and big worms crawling in the potting soil.
Complete fermentation of organic fertilizer is a slow process, and it must be an aerobic fermentation process to achieve complete fermentation. Burying it underground is even slower; the fastest method is to spray it wet and pile it up, then thoroughly turn it over every 5-7 days, and it will take about 6 months for the manure to fully ferment. Green manure (which is plant kitchen waste like melon and fruit peels) needs about 2 years (drying is definitely not fermentation!)
Directly applying animal manure or naturally stacking it for a few days before application, although the latter is safer than the former, both methods have great risks. Unfully decomposed organic fertilizers can pollute even more than chemical fertilizers, and the following hazards occur when unfermented organic fertilizers are directly applied:
1. Causes root and seedling burn
Applying unfermented animal manure can cause "secondary fermentation" due to incomplete fermentation. When fermentation conditions are met and microorganisms are active, the raw manure ferments. When the fermentation site is close to the roots or the plant is small, the heat produced by fermentation can affect plant growth, causing "root burn and seedling burn," and in severe cases, plant death.
2. Threat of diseases and pests
Feces contain bacteria like E. coli, nematodes, and other pests. Direct use can lead to the spread of diseases and pests, causing plant diseases and affecting the health of people who consume the agricultural products. Unfermented organic matter in the soil ferments easily, leading to the occurrence of plant diseases and pests.
3. Generation of toxic gases
Unfermented manure produces harmful gases such as methane and ammonia during decomposition, causing soil and plant acidosis and root damage.
4. Leading to soil hypoxia
Unfermented manure consumes oxygen in the soil during decomposition, temporarily causing the soil to be hypoxic. In this hypoxic state, plant growth can be inhibited.
5. Obvious slow fertilizer effect
Unfermented organic fertilizers contain nutrients mostly in organic or slow-release forms and cannot be directly absorbed and utilized by plants. Only when they are decomposed and converted into fast-release forms can they be absorbed by plants. Therefore, direct application without fermentation will slow down the fertilizer effect.
The above is an introduction to the methods of the harm of incomplete fermentation of organic fertilizer to roses, which can be used as a reference suggestion.
