How much fertilizer can a ton of organic fertilizer hold? I'll tell you the real data! (with the types, functions and matters needing attention of organic fertilizer)

Many farmers do not know how much chemical fertilizer is equivalent to a ton of organic fertilizer applied in the field. In fact, this question is expected to confuse everyone. For many years, this has been a muddled account, and it is not clear. However, now that detailed data are available, it can be used for reference when applying organic fertilizer.

1 ton of human feces and urine is equivalent to 25-40 kg of ammonium sulfate, 13-25 kg of calcium superphosphate and 4-6 kg of potassium sulfate.

1 ton of pig manure and urine is equivalent to 17 kg of ammonium sulfate, 21 kg of superphosphate and 10 kg of potassium sulfate.

1 ton of cow dung is equivalent to 16 kg of ammonium sulfate, 16 kg of calcium superphosphate and 3 kg of potassium sulfate.

1 ton of horse dung is equivalent to 28 kg of ammonium sulfate, 19 kg of calcium superphosphate and 5 kg of potassium sulfate.

1 ton of sheep dung is equivalent to 33 kg of ammonium sulfate, 31 kg of calcium superphosphate and 5 kg of potassium sulfate.

1 ton of chicken and duck manure is equivalent to 55-82 kg of ammonium sulfate, 88-96 kg of calcium superphosphate and 12-17 kg of potassium sulfate.

1 ton of rabbit dung is equivalent to 86 kg of ammonium sulfate, 184 kg of calcium superphosphate and 20 kg of potassium sulfate.

One ton of pig manure is equivalent to 23 kg of ammonium sulfate, 12 kg of calcium superphosphate and 12 kg of potassium sulfate.

One ton of cow manure is equivalent to 17 kg of ammonium sulfate, 10 kg of calcium superphosphate and 8 kg of potassium sulfate.

One ton of ordinary compost is equivalent to 20-25 kg of ammonium sulfate, 11-16 kg of superphosphate and 9-14 kg of potassium sulfate.

One ton of old wall soil is equivalent to 9.5 kg of ammonium sulfate, 28 kg of superphosphate and 16 kg of potassium sulfate.

1 ton of plant ash is equivalent to 219 kg of calcium superphosphate and 150 kg of potassium sulfate.

One ton of soybean cake is equivalent to 350 kg of ammonium sulfate, 83 kg of calcium superphosphate and 43 kg of potassium sulfate.

One ton of peanut cake is equivalent to 316 kg of ammonium sulfate, 73 kg of calcium superphosphate and 27 kg of potassium sulfate.

One ton of cottonseed cake is equivalent to 171 kg of ammonium sulfate, 102 kg of calcium superphosphate and 19 kg of potassium sulfate.

Types, functions and matters needing attention of Organic Fertilizer

Organic fertilizer is not soluble in water and decomposes slowly, so it is a late-acting fertilizer. It is mainly composed of organic matter, such as cellulose, hemicellulose, fat, protein, amino acids and humic acid, as well as various mineral nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and trace elements.

I. types of organic fertilizers

Considering the source, nature, composting method and prospect of fertilizer, organic fertilizer can be divided into several categories: farm manure, green manure, straw fertilizer, commercial organic fertilizer and so on. In addition, peat, peat, pond (river) mud river garbage are also important sources of organic fertilizer.

Second, the function of organic fertilizer

III. Commonly used organic fertilizer and matters needing attention

1. Human feces and urine

It is an excellent organic fertilizer, and its fertilizer effect is faster than that of general organic fertilizer. Fresh human feces and urine are neutral and contain more nitrogen, but less phosphorus and potassium, which should be combined with phosphorus and potassium fertilizer.

Note:

Long-term use alone will destroy the soil structure and cause soil consolidation. Therefore, it must be applied after fermentation and ripening, and it will not be mature until it is stored for 10 to 15 days.

The dung tank for storage should be in a more shady place, should not leak, and should be covered (to prevent ammonia volatilization); adding 2-3% calcium superphosphate can not only fix nitrogen and protect fertilizer, but also supplement phosphorus and improve the quality of fertilizer.

2. Barnyard manure

It is made of livestock manure, food residue and fiber cushion by fermentation and ripening. It is rich in organic matter, generally up to 15%, and as high as 30%.

Note:

Fresh barnyard manure contains refractory cellulose, lignin, etc., carbon and nitrogen is relatively large, and most of the nitrogen is organic. If fresh barnyard manure is used directly, it will compete with crops for fertilizer because it absorbs soil nutrients and water in the process of microbial decomposition.

3. Cake fertilizer

Also known as cruller (dry), is an oily seed, after the extraction of oil after the remaining dregs, as fertilizer to become cake fertilizer, rich in nutrients. Cake fertilizer is the best high-quality organic fertilizer for fruit trees, which is mainly used as base fertilizer, and is often mixed with compost and barnyard manure as base fertilizer, and can also be used as topdressing.

Note:

Topdressing should not be used until it is mature, and the cake fertilizer should be fully crushed and ditched and applied slightly away from the root system to avoid burning the root system during fermentation.

4. Compost and retting

Fertilizer made by composting or retting with straw, weeds, green manure, peat, garbage and human and animal feces and urine as raw materials.

Note:

The nutrient content and organic matter of high temperature compost were higher than that of ordinary compost.

5. Green manure

It is an important fertilizer source for producers. Leguminous crops are the main green manure crops in orchards, and their rhizobia have the ability of nitrogen fixation. Intercropping green manure has the functions of wide fertilizer source, convenient application, labor saving, self-sufficient fertilizer, improving soil and improving fertility.

6. Straw fertilizer

Straw not only contains cellulose, hemicellulose, lignin, protein and other organic matter, but also contains various elements necessary for crops, which can promote soil microbial activities and improve soil comprehensive fertility, and reduce the amount of chemical fertilizer.

7. Commercial organic fertilizer

Fertilizer made from by-product resources rich in organic matter, such as livestock and poultry manure, animal and plant residues, as the main raw materials, after fermentation and ripening. There are many kinds of commercial organic fertilizers, and their performance characteristics are also different.
