Can organic fertilizer be used as top dressing? How do I use it?

Organic fertilizer can be used as top dressing, which contains many nutrients. When there are no nutrients in a plant, using organic fertilizer as top dressing will transfer all the potassium in it to the plant. Plants are to be topdressed in the later stage, so that they can grow very lush, and will also exert the effect of the inside on the plants.

If the crop is to be topdressed with organic fertilizer, it must be in moderation, otherwise it will also harm the plant. <>

There is a lot of pig and cow manure in the countryside, which can be used as organic fertilizer, but it must be used after fermentation. Pig manure is very good and can be used as top dressing because the feed that pigs eat is very nutritious, and the pigs have been pulled out before they have digested it. Some people think that the smell of pig manure is not good, but gradually top dressing these organic fertilizers can enhance the nutrition of plants in plants.

When the temperature is relatively high, pig manure can also be decomposed and can also produce a certain amount of water, which is very helpful to plants. These natural substances in the countryside can have the effect of top dressing, and they are also very good. <>

When you grow fertilizer, you should understand what the correct use of organic fertilizer is. For example, if you put some organic fertilizer on the land, you can make the soil very rich and will not cause certain obstacles. No matter what plant you want to plant, as long as you choose the right fertilization method, you can quickly fix it.

Plants need a lot of nutrients to grow, and organic fertilizer can be used well as top dressing. Farmers want to use chemical fertilizer instead of organic fertilizer, so they will find it themselves. <>

In general, when the structure of the soil is continuously improved, the plants will grow better. There is a certain demand for top dressing, not to say that it should be increased in excess all the time. Don't put some pesticides on the plants, it will lead to the gradual reduction of some microorganisms, and there is no way to make the plants grow better.

If you want to plant fruit trees, you must also master the method, and you can't use too much.

Of course, it is possible, it needs to be determined according to the growth of the plant, as long as there is no problem with the growth of the plant, it can be used in this way, and it must be noted that the weather is not allowed to fertilize when it rains.

Organic fertilizer can be used as top dressing. As a commonly used fertilizer in agriculture, organic fertilizer is often applied to crops in a certain proportion, and the concentration should not be too high.

Organic fertilizer can be used as top dressing, and there are two methods of top dressing of organic fertilizer: soil application and extra-root top dressing.

Basal fertilizer (base fertilizer) application.

Basal fertilizer, generally called base fertilizer, is a fertilizer that is applied before sowing or transplanting. When ploughing, the organic manure is evenly applied, and the fertilizer is turned into the soil with the ploughing, this method is simple, easy to operate, can play a good purpose of improving the soil, but in its uniform application to the soil, can not all or even most of the contact with the root system and be utilized by the root system, therefore, the fertilizer utilization rate is bound to cause excess waste, bring certain economic losses, and secondly, it is easy to produce soil obstacles. Therefore, this method is more suitable for planting crops with higher densities.

Top dressing application. There are two methods of topdressing for organic fertilizer: deep soil application and extra-root topdressing. Deep soil application generally applies organic fertilizer near the dense layer of the root system, and covers the soil after application to avoid the loss of nutrient volatilization. Extra-root topdressing is to mix the compost with 10 times the water evenly, take its supernatant after standing, and spray the fertilizer solution on the foliar surface of the crop with the help of a sprayer for foliar absorption.

It is used as seed fertilizer. There are many ways to use seed fertilizer, such as seed dressing, soaking, strip application, hole application, etc. Seed dressing is a method of dissolving or diluting fertilizer with a small amount of water, spraying on the surface of seeds, and mixing while spraying, so that the fertilizer solution is evenly stained on the surface of the seeds, and sown after drying. Soaking is to dissolve or dilute the fertilizer solution into a solution of a certain concentration, according to the liquid type 1:

10 ratio, put the seeds into the solution and soak for 12 24h, so that the fertilizer liquid infiltrates into the seed coat with water, and then sow after drying. After ditching or digging holes, fertilizer is applied into the ditch and hole of 3 5cm of the cultivated layer, and then sown near the fertilizer belt, and the distance between the fertilizer is kept above 3cm. Used as seed fertilizer, fertilizer requires the release of nutrients to be fast, can not be too acidic, too alkaline, the fertilizer itself has no toxic effect on seed germination, and the organic fertilizer that is fully decomposed after composting is a good seed fertilizer.

Used as seedling fertilizer.

Fully decomposed organic fertilizer, evenly released, comprehensive nutrients, is an ideal fertilizer for seedlings. Generally, 10% fermented organic fertilizer with sufficient fermentation is added to a certain amount of peat, fly stone or perlite, and the soil is mixed evenly to make seedling substrate.

Full-layer fertilization of organic fertilizer and full-layer fertilization of concentrated fertilization is to sprinkle organic fertilizer all over the surface, and apply organic fertilizer into the whole soil layer through cultivated land, this fertilization method can be applied in the case of more organic fertilizer (4000 6000kg per mu) or crop density. Concentrated application into the soil is to apply compost near the root system of crops by ditching, and this fertilization method is worth using when there is less fertilizer (1500 3000 kg per mu) and soil fertility is relatively low.

1. Organic fertilizer is the main fertilizer, supplemented by chemical fertilizer. Second, apply sufficient base fertilizer and reasonable top dressing. 3. Scientific proportioning and balanced fertilization.

Fourth, pay attention to the chemical reaction and antagonism between the nutrients. 5. Prohibited and restricted fertilizers. The details are as follows:

Organic fertilizer is the main fertilizer, supplemented by chemical fertilizer. Use manure, cake fertilizer, manure, compost, manure, etc., as well as high-quality organic fertilizer processed by factory, such as puffed chicken manure, microbial fertilizer, organic foliar fertilizer, etc. Formula fertilization is based on soil fertility and crop nutrient requirements.

Apply sufficient basal fertilizer and reasonable top dressing. In the fertilization method based on organic fertilizer, more than 70% of the total fertilizer content of organic fertilizer is used as base fertilizer, and the fertilizer content is not easy to lose when applied to the soil before planting, and can improve soil properties, improve soil fertility, and top dressing should be based on crop growth and demand, mainly fast-acting fertilizer. A variety of methods such as root zone sprinkling, furrow application, hole application, water and fertilizer and foliar spraying were adopted.

Scientific proportioning, balanced fertilization. Fertilization should be adjusted according to soil conditions, crop nutrient requirements and seasonal climate change and other factors, the ratio and dosage of various nutrients should be adjusted to ensure the balanced supply of nutrients required by crops. In addition to organic fertilizers and chemical fertilizers, microbial fertilizers, trace element fertilizers, amino acids and other nutrient solutions can be used as nutrient supplements for crops by root application or foliar spraying.

Summary. Hello dear. Yes.

How to use; First, organic fertilizer can be applied in advance. Organic fertilizer is a long-lasting fertilizer, which needs to be combined with water and temperature to slowly release various nutrients, so farmers should apply watering and fermentation in advance before planting. Generally speaking, high-quality organic fertilizer generally grows white hairs (mycelium) after 7 days in summer, 8 to 12 days in autumn, and 15 to 20 days in winter and spring, and then organic fertilizer begins to release nutrients.

Therefore, farmers should grasp the fertilization time to maximize the fertilization benefits.

Can organic fertilizer be used as top dressing? How do I use it?

Hello dear. Yes. How to use; First, organic fertilizer can be applied in advance.

Organic fertilizer is a long-lasting fertilizer, which needs to be combined with water and temperature to slowly release various nutrients, so farmers should apply watering and fermentation in advance before planting. Generally speaking, high-quality organic fertilizer generally grows white hairs (mycelium) after 7 days in summer, 8 12 days in autumn, and 15 to 20 days in winter and spring. Therefore, farmers should grasp the time of fertilization bucket to maximize the benefits of fertilization.

second, it can be concentrated or striped; Sometimes the front stubble is late, and when the stubble is topdressed or intercropped and fertilized, it can be applied locally or striped. This method can be used to collect fertilizer, improve fertilizer efficiency, and the effect is also very good. Third, you must not apply manure; Livestock and poultry manure is high-quality organic fertilizer, but contains a lot of uric acid, easy to burn roots, burn seedlings, smoke leaves, at the same time there are insect eggs and bacteria in the raw tung hand manure, which is very harmful to vegetable planting, so raw manure must be piled up and fermented, covered with film, and checked frequently.

When white hairs appear, the feces have been decomposed, and the eggs and spores have been killed, so they can be used or dried for storage; Otherwise, when the stool residue continues to ferment and the gross nucleus appears yellow hair, the nutrients of the feces have been destroyed; By the time green hair appears, the feces have already produced a large amount of virus. Mastering the three links of sock digging is the key to the fermentation of the pile. If you are not very familiar with the fermentation of raw manure heaps.

You can directly buy organic fertilizer from the market and apply it.

1. Fertilizer (farm organic fertilizer): It must be fully decomposed and fermented before use. Organic fertilizer can activate the soil, improve the soil, enhance the disease resistance, insect resistance and disaster resistance of crops, improve the quality of crops, and increase yields.

However, organic fertilizers such as natural poultry pens, human and animal manure and cake meal must be fully decomposed and fermented before they can be applied. After fermentation, firstly, the acidity in the organic fertilizer is balanced, the nitrate content is reduced, and the water is replenished, which is conducive to the combination with the microorganisms in the soil. Secondly, after fermentation, it can kill parasite eggs, pests and bacteria in the raw manure, which directly affects crops and soil.

Second, improve the fertilization method, one is to apply as deep as possible or cover the soil surface, avoid the phenomenon of surface fertilizer, reduce the loss and waste of fertilizer and environmental pollution; Second, the basal fertilizer at the seedling stage of crops should be applied deeply or early, especially the amount of nitrogen fertilizer at the seedling stage should be strictly controlled; Third, it is necessary to fertilize according to the law of crop growth and nutritional needs, and the crops with a short growth period can be applied to the bottom fertilizer at one time, such as cotton seedling fertilization, such as the seedling period is longer, it should be divided into light and heavy, in order to achieve the expected yield effect.

First, the nutrients contained in organic fertilizer are more comprehensive, but they are not balanced, and cannot fully meet the different needs of various crops for nutrients. Organic fertilizer contains many types of nutrients, which is an advantage compared with a single nutrient fertilizer, but its nutrient content is low, and there is also an imbalance problem, which can not meet the needs of high yield, high quality and income increase of crops. When applying organic fertilizer, chemical fertilizer should be applied according to the requirements of crops for nutrients, so as to achieve balanced fertilization, even if the farmland that produces green food should be equipped with mineral fertilizer, and spray various foliar fertilizers according to the actual situation during the growth of crops to ensure the normal growth and development of crops.

Second, the effect of organic fertilizer is slow. Organic fertilizer not only has a low total nutrient content, but also has a slow fertilizer effect, and it is difficult to meet the needs of crops for nutrients when the amount of organic fertilizer is not very large. Therefore, it is necessary to take advantage of the high nutrient content and rapid fertilizer efficiency of chemical fertilizer, apply organic fertilizer and chemical fertilizer together, help each other with urgency, learn from each other's strengths, give full play to the mixed advantages, and meet the demand for various nutrients in the quantity and time of crop growth and development.

3. Organic fertilizer needs to be fermented. Many organic fertilizers contain germs, insect eggs and weed seeds, and some organic fertilizers contain organic compounds that are not conducive to the growth of crops, so they should be fermented and processed before they can be applied, and the raw manure can not be put into the ground.

Fourth, there are differences in composition and nature between organic fertilizer raw materials, so that after being applied to the soil, there are also differences in the effect on soil and crops. Therefore, according to the texture and climate of the planting soil, the growth habit and fertilizer characteristics of the planting crops, the appropriate organic fertilizer should be selected for reasonable fertilization. For example:

Human feces and urine contain a large amount of chloride ions, and the application should be avoided on chlorine-resistant crops.

Fifth, the more organic fertilizer is not the better. Organic fertilizers are large and low in nutrients, and need to be applied in large quantities to meet the growth needs of crops, but more is not always better. Because organic fertilizers, like chemical fertilizers, also have the problem of metered application in agricultural production.

If too much organic fertilizer is used, it is not only a waste, but also can cause soil obstacles and affect the growth and development of crops. For example, in the cultivation of protected areas, if a large amount of organic fertilizer is applied for a long time, it can also lead to excess soil nutrients and soil salinization, which can cause problems such as poor growth of agricultural products, excessive nitrate content, and quality decline. Therefore, the amount of organic fertilizer in production should be used reasonably according to the consumption of various nutrients and organic matter in the soil, so as to achieve formula fertilization and scientific fertilization.

Sixth, the application method of organic fertilizer should be appropriate. Organic fertilizer should be applied by ditching strips or digging pits, centralized fertilization, and timely soil covering after application; If sprinkler applicator is used, it should be turned into the soil after application. Generally, organic fertilizer is mixed with chemical fertilizer for better effect.

For example, superphosphate mixed with organic fertilizer can greatly improve fertilizer efficiency.

7. Well-rotted organic fertilizer should not be mixed with alkaline fertilizer, if mixed with alkaline fertilizer, it will cause ammonia volatilization and reduce the efficiency of organic fertilizer.

(1) The nutrients contained in organic fertilizer are not a panacea.

Organic fertilizer contains many types of nutrients, which is an advantage over chemical fertilizers with single nutrients, but the nutrients it contains are not balanced.

2) The decomposition of organic fertilizer is slower and the fertilizer efficiency is later.

Although the organic fertilizer has a full nutrient content, the content is low, and the decomposition in the soil is slow, and it is difficult to meet the needs of crops for nutrients when the amount of organic fertilizer is not very large.

3) Organic fertilizer needs to be fermented.

Many organic fertilizers have germs, insect eggs and weed seeds, and some organic fertilizers contain organic compounds that are not conducive to the growth of crops, so they should be fermented and processed before they can be applied, and raw manure can not be used in the ground.

4) The use of organic fertilizer is contraindicated.

Well-rotted organic fertilizer should not be mixed with alkaline fertilizer and nitrate nitrogen fertilizer.
