There are many simple ways to make organic fertilizer, and the three commonly used methods are composting, fermenting food waste, and making fermentation broth for animal manure. Compost is an organic matter fertilizer formed by accumulating plant residues and agricultural wastes through microbial decompositionFood waste fermentation is the fermentation of daily food waste such as vegetable and fruit peels, food residues, etc.;Animal manure fermentation is the use of livestock manure, plus the right amount of water and starter culture, to make liquid fertilizer. These methods can not only recycle daily waste in rural areas and reduce environmental pollution, but also provide nutrient-rich fertilizers and promote the growth of crops.
First, the secret of organic fertilizer in the soil.
In the rolling green fields, the wisdom of the farmers is like a continuous spring of water, nourishing every inch of the land. The production of organic fertilizer is the crystallization of this wisdom. Organic fertilizer not only gives the soil rich nutrients, but also perfectly combines with the concept of environmental protection, which can be called the "green expert" in agriculture.
First, let's talk about composting. It is a time-honored technique, like a family heirloom sword handed down from our ancestors, that is both strategic and methodological. The secret to the success of composting lies in three key points: carbon to nitrogen ratio, microorganisms and breathability. The carbon-to-nitrogen ratio, just like the heat of stewed meat, should not be too strong or too weak, and is generally kept between 25:1 and 30:1 for the best. Microorganisms, the heroes behind composting, rely on their superpowers to break down organic matter to make compost mature quickly. As for ventilation, it is necessary to ensure that these little friends can be alive and active, and occasionally turn over the compost to let the air in, take away the excess moisture, and let the microbes work more comfortably on the "mattress".
Next, let's take a look at food waste fermentation. It's like cooking a delicious home-cooked meal with just the right ingredients. There is a lot of water in kitchen waste, so it is necessary to control water and salt, and add some bran, sawdust, etc., to help absorb water and increase air permeability. Then, add some starter culture, let them "brew" in an airtight container, and after a few weeks, you will have a fragrant fertilizer.
Animal manure fermentation broth, thanks to the little animals in the farmyard. Their "product", after fermentation, becomes a liquid**. When making, pay attention to dilution, usually with the ratio of 1 part manure to 10 parts water, and then add a little starter culture to promote its faster transformation. This fertilizer is not only nutritious, but also easy to use, and is simply a delicious "soup" for those plants who prefer liquid fertilization.
Second, the fertilizer code from ancient times to the present.
Looking back at the long river of history, agriculture is the cradle of human civilization, and fertilizer is the milk that nourishes this cradle. Since ancient times, farmers in our country have known how to use natural substances such as manure, green manure and bone meal for farming, which are the early forms of organic fertilizer. With the development of science and technology, the production and application of organic fertilizers are becoming more and more scientific and refined.
Globally, organic farming is becoming a trend, and at the heart of it is the homemade and use of organic fertilizers. Some countries in Europe, such as Germany and the Netherlands, have reached the level of art in organic fertilizer production, turning agricultural waste into treasure, not only improving the fertility of the soil, but also protecting the environment.
So, how can you make high-quality organic fertilizer?In addition to the key steps mentioned above, such as fermentation and water control, it is also necessary to understand the chemical composition of organic matter, the effects on soil microorganisms, and the recycling of nutrients in fertilizers. Nitrogen, for example, is an important nutrient for plant growth, but too much of it can lead to eutrophication of water bodiesPhosphorus and potassium, which are also important elements needed for plant growth, need to be in moderation.
My personal experience has taught me that no matter what kind of organic fertilizer you are, you have to pay attention to the formula and proportion. For example, one of the recipes I used in my own garden was to mix straw, leaves, animal manure and a certain amount of soil and turn it regularly to maintain the right humidity and climatic conditions. After a few months, when the compost becomes delicate and dark, it means that the fertilizer is fully ripe and ready to use.
