-Indian environmental philosopher Fandana Shiva
Soil is not only the material basis for human survival and the source of precious wealth, but also the earliest means of production for human development and utilization. In human history, the decline of soil quality has left a painful lesson for human civilization and social development. With the growth of global population, the sharp decrease of cultivated land, the exhaustion of resources and the rapid expansion of the influence of human activities on natural systems, people's understanding of soil is deepening. Like water and air, soil is not only an irreplaceable or scarce natural resource for producing food, fiber and forest products, but also the basis for maintaining the vitality of the earth system and the prosperity of the whole human society and biosphere. Therefore, it is particularly important to protect soil, especially the quantity and quality of cultivated land.
"People take food as the sky, and food is based on soil", which brilliantly summarizes the relationship among human beings, agriculture and soil. Agriculture is the foundation of human existence, and soil is the foundation of agriculture.
Good soil should enable plants to eat enough (sufficient nutrient supply), drink enough (sufficient water supply), live well (adequate air circulation and temperature) and stand firmly (extended roots and firm mechanical support). At present, in our protected cultivation, there are more and more plants that are overindulged and "accumulated food" and soil that is "fed thin".
Obviously, there is no shortage of fertilizer and money, but there are yellow leaves, premature aging and low yield; Obviously, a lot of base fertilizer is used, but there are more and more problems of moss, red rust, white rust and hardening in the soil. The roots of plants are no longer huge, with few roots, sparse capillary roots and blackened roots. ...
Why are there these problems?
Some people analyze the factors affecting the growth potential of crops as follows. If the growth potential of crops is 100% in an ideal state, the influence of salt damage on the better growth potential of plants is enormous.
Yes, it is salt damage!
Where does the salt come from?
In fact, all soils, whether alkaline, acidic or neutral, loam, sandy soil or clay, contain salts of cations such as calcium, magnesium and potassium, as well as common negatively charged anionic chlorides, nitrates, sulfates and phosphates. The difference is that some soils contain moderate "salt", which does not pose a threat to crops and can provide nutrients for crops well. However, the "salt" in some soils exceeds the standard, causing secondary salinization and threatening the healthy growth of crops.
So, where do these extra "salts" come from?
1.？ Chicken manure and duck manure are used as base fertilizers.
Some people vividly describe chicken manure as a double-edged sword. Chicken manure not only brings rich organic matter to the soil, but also brings some salt. In the process of raising chickens and ducks, a certain amount of salt is usually added to the feed to maintain the normal electrolyte balance of chickens and ducks, and the salt will be excreted with the digestive system. Some data show that the salt content of one ton of chicken manure is about 12 kg. These salts accumulate in the soil with the increase of the use times of chicken and duck manure. The accumulation of sodium ions makes the originally healthy soil lack certain polymerization, resulting in the problems of water accumulation when wet and hardening when dry. However, excessive accumulation of chloride ions will cause certain toxicity to crops.
2.？ Unscientific fertilization, excessive fertilization
With the continuous development of soil testing and formula fertilization, more and more farmers begin to apply fertilizer reasonably according to soil testing data, especially large farms or large-area farmers, who will analyze the soil scientifically before applying fertilizer. However, a large number of small farmers still apply fertilizer by experience, which is an important reason why the soil salt content in protected areas exceeds the standard at present. Excessive phosphorus application leads to excessive phosphorus, which leads to the fixation of iron, calcium and magnesium and cannot be absorbed by roots normally. Crops suffer from iron deficiency, such as yellow head, navel rot, rotten head and "feathered leaves" (caused by magnesium deficiency) ...... and these salts-nutrients accumulate too much in the soil, which not only wastes resources, but also leads to the increase of root osmotic potential and can't absorb water normally. Over time, the soil has become a "pickle jar". Moss, red rust, white rust and hardening increased, and the soil in the shed was overwhelmed.
3.？ The soil aggregate structure has been seriously damaged.
It is precisely because of the accumulation of some "salt" that the aggregate structure of soil is destroyed. The normal aggregate structure can not only keep water and fertilizer well, but also has certain pores, which can make the roots and beneficial microorganisms breathe more smoothly. Reasonable pores can also help excess salt to be leached into the deep soil by water without affecting the roots of cultivated crops. The destruction of particle structure leads to the failure of normal leaching of excessive salt. On the other hand, due to the capillary action of the soil itself, the salt in the deep soil or water will rise to the surface of the soil and accumulate with the capillary action, which will make the salt in the topsoil exceed the standard.
The vicious circle of "salt"
Frequent watering and fertilization, excessive application of chemical fertilizer and chicken manure, long-term continuous cropping and unscientific formula fertilization will seriously destroy the physical fertility, chemical fertility and biological fertility of healthy soil, greatly reduce the activity of soil enzymes, lead to excessive accumulation of "salt" and secondary salinization, more and more green and red white boards, poor root development of plants and yellow leaves.
However, some farmers don't know the cause of the problem and are eager to increase the yield, so they want to solve the problem by applying a lot of fertilizer. This forms a vicious circle of salt.
Desalination scientist -Dichotsu
Looking at Dutch agriculture, most of the land in the Netherlands is reclaimed from the sea, and the soil is seriously salinized. In order to pursue high yield and bear more fruits on limited land, they also took many detours. Blind application of chemical fertilizer once led to the intensification of soil secondary salinization. Due to the scarcity and preciousness of land, Dutch farmers have developed efficient and intelligent greenhouses integrating water and fertilizer. Iprun in the Netherlands has also specially developed a patented technology to solve soil salinization-IPE phosphorus synergy technology to reduce the salt in the soil.
IPE technology is science, not magic!
Dichotsu is a new generation of organic liquid water-soluble fertilizer based on IPEP technology, which can effectively prevent phosphorus solidification and activated phosphorus solidification. It is rich in various organic substances and promotes the synthesis of various enzymes in crops.
Functional characteristics of Erguotou
1.？ Dichotsu remoulds the chemical fertility of healthy soil.
IPE patented technology can release nutrients such as phosphorus, iron, calcium and magnesium fixed in soil and be absorbed and utilized by crops. At the same time, it will prevent the newly applied nutrients from being fixed by the soil and ensure the chemical fertility of healthy soil.
2.？ Dichisu reshapes the physical fertility of healthy soil.
The organic matter contained in dieldrin can effectively help the soil to form more aggregate structure, improve the ability of water and fertilizer conservation, and at the same time make the soil have good porosity, so that the roots can be better tied and stretched.
3.？ Dichotsu remoulds the biological fertility of healthy soil.
Dieldrin is helpful for beneficial microorganisms in soil to form dominant flora and secrete more substances to promote root growth.
4.？ Trichlorfon supplemented soil enzymes to improve enzyme activity.
Dieldrin contains 60 kinds of soil enzymes, which can help the soil to carry out various metabolic processes and energy conversion, improve soil vitality and form a healthy soil cycle.
On the road of exploring scientific formula fertilization, weight loss and efficiency fertilization technology, Yi Purun has enabled more and more farmers to witness the "salt reduction miracle" of the red pigment!
