What should I do if the land lacks fertilizer, and what fertilizer does the general loess lack

Sawdust can go to the construction site to ask, each construction site has a carpentry shed, there are a lot of sawdust, now there are construction sites everywhere, it is not difficult to order sawdust.

In fact, the organic garbage such as vegetable leaves, fruit peels, leftovers, watermelon peels and other organic garbage at home are very good fertilizers, but they are troublesome to make, don't look at the small amount per day, the time is considerable, if you give up the sauce with a crusher, you can bury it directly into the soil, and you can also save the process of making it, and it should be scattered when buried, and insects will be born when piled together. There is also rice washing water, water for washing fish meat, and it will be very fat if poured directly into the mud.

If you encounter a lawn in the community, this grass is taken to dry, sprinkled with some water and wrapped in a bag to rot, and it is also good to participate in the flower bed soil.

At present, the soil is very boarded, and the soil surface can be covered with plastic paper. Wait for the grass to grow before removing it. When the grass grows tall, just cut it short, don't weed, and the live grass roots will produce a clump structure. The soil is crispy and breathable.

If the water is not poured through, you can use the beverage bottle to remove the bottom, the bottle mouth is downward, two-thirds of it is straightened, the water is drip irrigated, and the drip speed is adjusted by screwing the cap.

Yes, it is not enough to use more organic fertilizer at home, and the cow manure and chicken manure in the village are fermented, and the effect is good.

If the chemical fertilizer is applied excessively, the soil quality will get worse year by year, and you can apply more organic fertilizer with fertile leaf fertilizer to apply it together, and the effect is the best.

The combination of land use and land cultivation, and the combination of preventing fertility decline and soil treatment are the basic principles for maintaining and improving the level of soil fertility.

Specific measures include the application of organic fertilizers, the planting of green manure and the rational application of chemical fertilizers, so as to contribute not only to the high yield of current crops, but also to the restoration and improvement of soil fertility. For some low-yielding soils (acidic, alkaline and saline), chemical amendments and irrigation should be used to improve the fertility level by removing obstacles.

In addition, reasonable tillage and crop rotation should be carried out to regulate nutrients and water in the soil and prevent certain nutrient deficits and water vapor imbalances; Prevent soil contamination by heavy metals, pesticides and other pollutants; Rationally arrange the layout of agriculture, forestry and animal husbandry according to local conditions, and promote the recycling and reuse of biological matter; Prevent the occurrence of various degradation phenomena such as soil erosion, wind erosion, secondary salinization, desertification and swamping, protect forests and grasslands, and maintain ecological balance.

Summary. What fertilizer is lacking in the general loess, there are more silicates in the loess, and nitrogen, phosphorus and potassium fertilizers are generally used in the loess, and compound fertilizers.

Thank you. What fertilizer is lacking in the general loess, there are more silicates in the loess, and nitrogen, phosphorus and potassium fertilizers are generally used in the loess, and compound fertilizers.

Which fertilizer needs to be more in more proportions.

Ratio of nitrogen, phosphorus and potassium.

Autumn fertilization should be based on organic fertilizer, and with some nitrogen, phosphorus, potassium and other fast-acting fertilizers, but also need medium and trace elements. It is best to apply organic fertilizer containing fulvic acid; A large amount of Yuanbo Lisu can be used as potassium sulfate compound fertilizer, and the ratio of nitrogen, phosphorus and potassium is 3:2

1. It is advisable to take about 1, mainly nitrogen and phosphorus, followed by potassium; Medium and trace elements, which can be supplemented according to the law of fruit tree fertilizer, including calcium, magnesium, silicon, sulfur, zinc, iron, boron, manganese, molybdenum and other 16 kinds of medium and trace elements and rare earths, these fertilizers play a great role, but are easily ignored by fruit farmers. Apples and grapes require more fertilizer than other fruits, so they should be applied more. Young and vigorous trees need less fertilizer and can be applied less.

According to the law of fertilizer demand of fruit trees, the nutrients required for each fruit production are different, for example, the ratio of nitrogen, phosphorus and potassium required by apples and pears is 2:1:2, and that of peach trees is 5:

2：8。For example, for every 100 kilograms of apples produced, kilograms of pure nitrogen, kilograms of pure phosphorus, and 1 kilogram of pure potassium are needed.

I grow corn.

The fertilizer ratio for planting corn is urocarn, potassium sulfate, and ammonium dihydrogen phosphate additives. Nitrogen fertilizer is generally absorbed the most by corn in nano, followed by potassium, phosphorus, calcium, magnesium, sulfur, etc., on average, every 100 catties of grain produced needs to absorb pure nitrogen kilograms from the soil, phosphorus and 2 kilograms of potassium, the proportion is about: 1.

Corn generally absorbs the most nitrogen fertilizer, with a ratio of about 1::1.

Summary. Dear, hello, loess is generally deficient in all nutrients, so nitrogen, phosphorus and potassium fertilizers, compound fertilizers are needed, and the specific fertilizer plan depends on what <>crops you are planting

Dear, hello, the yellow file song land is generally rotten Zheng has a lack of nutrients, so nitrogen, phosphorus and potassium fertilizer, compound fertilizer are needed, the specific fertilizer plan depends on what kind of crop you plant, the history of the reeds <>

Expansion: Loess can be used: organic fertilizer, biological fertilizer, bio-organic and inorganic compound fertilizer, commercial organic fertilizer, organic non-trap machine compound fertilizer, and with an appropriate amount of potassium sulfate compound fertilizer as base fertilizer and base fertilizer. The following foliar fertilizers can also be used for top dressing to promote long limb shouting.

You can give half of what you grow to the land, and make the land fertile by rotting.

In addition, it is recommended that you apply some fertilizer and go to the toilet simply in the field.

The land is not fertile and needs to be nourished, and the people are few and the land is poor.

Apply organic fertilizer to buy dry chicken manure as fertilizer, and use it deeply.

Fertilization, it is best to see what fertilizer is missing.

Don't plant the same plant, you can plant multiple plants.

You need goldenrod (rich in nitrogen, phosphorus and potassium).

Corn floor fertilizer and top dressing are not on?

If there is none, then it will definitely not be nutritious.

Reference: Use corn fertilizer, zinc, 30-5-5, or 28-6-6. 50kg per mu.

It is best to use it according to your local soil and under the guidance of an agricultural technician.

You go buy fertilizer, explain the situation, and they will give you recommendations.

Fertilization should be covered with soil, and bio-organic fertilizer can be added to regulate the soil.

The land is barren and should be solved from the following aspects:

1. Increase the application of farm fertilizer, and return the straw to the field as much as possible after harvesting, so as to increase the humus in the soil and improve the soil.

2. Govern the land to prevent soil erosion.

3. Carry out soil testing and fertilization, scientific cultivation, and prevent soil salinization.

The fastest way to do this is to apply urea in combination with watering. In terms of long-term benefits, it is best to apply organic fertilizers, such as chicken manure, pig manure, etc., when the land is poor.

Generally speaking, soil barrenness is mainly caused by the lack of organic matter in the soil, and there is generally a lack of soil nutrients caused by soil compaction, desertification, etc., and poor fertilizer and water retention. Generally, the main soil improvement is mainly the application of organic fertilizer containing organic matter, basal fertilizer, and it takes one year for the soil to be significantly improved.

In order to enhance soil fertility and increase land productivity, soil organic matter must be increased. Increasing soil organic matter can be achieved through the following four ways: 1. Promote straw returning to the field.

Straw returning is an important way to increase soil nutrients, increase soil organic matter content, improve soil physical and chemical properties, potassium and phosphorus nutrient conditions, and enhance soil microbial and enzyme activities. Especially in recent years, the early rice mulching, late rice no-tillage cultivation technology, wheat field, rapeseed, milk vetch and early crop grass cover technology, not only adapt to the characteristics of current agricultural production, but also play a role in grass fertilization, grass moisturizing, grass temperature regulation, grass soil protection, grass pressing, labor-saving farming and other multiple roles, both organic fertilizer, biological mulch film and soil protection vegetation multiple advantages. This technology has the basic characteristics of traditional agriculture and modern agriculture, and has strong vitality and broad development prospects.

2. Develop green manure production. The development of green manure production is not only an effective way to increase the source of organic nitrogen and enrich the phosphorus, potassium and trace elements in the soil, but also a link between agriculture and animal husbandry. China Bio-Organic Fertilizer Trading Network reminds you that the nitrogen resources contained in green manure exist in the form of protein, which can directly provide essential protein for humans and animals, and is a high-quality animal husbandry feed.

3. Improve the utilization rate of human and animal manure. In the 60s of the 20th century, the peasants summed up the experience of "four diligence" (diligent sweeping, diligent mats, diligent out, diligent accumulation), "four haves" (cattle have pens, pigs have pens, manure ponds, and fields have green manure) are still not outdated, we must further conscientiously sum up these traditional experiences, and gradually improve them, and continue to carry them forward. 4. Promote commercial organic fertilizers.

Since entering the 21st century, refined organic fertilizer and organic and inorganic compound fertilizer have become the "rookie" in the fertilizer industry. Looking forward to the development trend of fertilizers in this century, organic fertilizers will be applied to the soil in the form of commercial organic fertilizers and organic and inorganic compound fertilizers, in addition to returning to farmland directly or after treatment. With the increasing demand for organic fertilizer in green food production, organic and inorganic compound fertilizer will gradually develop to organic fertilizer-based, transport a small amount of inorganic fertilizer to the concentration of organic fertilizer resources, adjust the proportion of nitrogen, phosphorus and potassium in organic fertilizer or increase the available nitrogen in organic fertilizer, so as to give full play to the role of organic fertilizer.

In short, the application of organic fertilizer, is the traditional agricultural technology and modern agricultural science and technology combined, is the relationship between inheritance and development, but also the best way to recycle materials in the process of production and life, only the increase of organic fertilizer, in order to achieve the purpose of enhancing the soil to promote "agricultural efficiency, farmers' income".
