Why counterfeit seeds and fertilizers are dangerous
Gardeners often face the problem of poor seed germination. And the point here is not in violation of storage conditions or care. According to experts, 25-30% of products on the seed market are counterfeit. The situation with fertilizers is no better: almost 55% of them are outright falsifications. It is dangerous to use them on site.
According to statistics, every third packet of seeds is unsuitable for sowing: in the best case, the germination rate will be 50%, but usually it does not exceed 15-30%. Most often this is due to the fact that the manufacturer dilutes the normal seed with open dust, chipped, cracked and even expired and moldy seeds. Unscrupulous manufacturers do not worry about the quality of the products, so you can get seeds infected with fungi, viral infections.
Sometimes even eggs and larvae of pests come across in sachets with counterfeit products.
If the seeds are nevertheless treated against parasites and fungi, hazardous chemicals and insecticides are most often used for these purposes. Plants grown from this seed can be harmful to health; as one seed, you can get another. But it's not so scary if instead of carrots you sprout parsley.
It is worse if you grow a poisonous plant in your beds.
So, a few years ago, blueberry seeds were in great demand. It should be noted that this berry is cultivated by cuttings, not seeds. However, there were many buyers. The seller promised a high harvest next year, and the bushes were indeed covered with black and red berries. But it was not blueberry, but nightshade - a poisonous plant that can be easily poisoned.
More than half of the fertilizers present on the market do not comply with regulatory documents. Salts of heavy metals are often found in mineral fertilizers, and organic additives can be contaminated with pathogenic and phytopathogenic bacteria.Growing vegetables on such a top dressing is extremely dangerous to health. In addition, the harmful impurities contained in such a fertilizer have a negative impact on the environment. If the concentration of harmful substances in the counterfeit does not exceed the norm, it will still not be beneficial.
An imbalanced composition in a fake fertilizer will lead to suppression of plant growth.
The crops grown will not receive the nutrients they need, which means that the harvest will be scarce. In the worst case, using a fake will completely ruin the crops and leave you without a crop.
Nitrogen content in soil
It was found that a significant proportion of nitrogen in the earth is concentrated in its layer, called humus, in it more than 5% of nitrogen. Naturally, the thicker the layer of humus, the more and the amount of nitrogen, therefore, plants feel better on such soil.
Humus is a very persistent substance, the process of its decomposition is unhurried, therefore, the release of minerals from this layer is also rather slow. Only one percent out of five that is in the soil is a mineral compound that is soluble in water, and therefore available for consumption by plants.
Therefore, even in the presence of a thick layer of humus, additional plant nutrition is needed, albeit in lower doses.
Gray rot of grapes
This remedy has proven itself also on grapes. In this case, you can kill two birds with one stone: not only rid the lashes of powdery mildew, but also protect them from gray rot. In order to prevent this disease, grapes are treated with soda elixir (4 tablespoons per 10 liters of water) with an interval of 10-14 days.

Loss of vitamins during transportation and storage
There is another important factor affecting the content of vitamins in plants. These are unfavorable conditions for the transportation and storage of fruits and vegetables.
For example, a study analyzed broccoli and how its nutrient content changes until it hits store shelves. The study was carried out on rats, fed and observed the effect on morbidity. The result of the study is alarming: broccoli has lost its anti-cancer properties, as well as its properties that are responsible for reducing the risk of heart attack or stroke.
Other studies come to similar conclusions. Spinach loses all of its antioxidants in just one week. Cabbage loses 60-89% of its original vitamin C content within two days at room temperature.
Are your fruits and vegetables stored at temperatures below 2 ° C in the supermarket? Probably not. Why? Either because of ignorance or to keep costs down. The fact that fruits and vegetables must be constantly cooled, both during transportation and during storage, is an indisputable fact.
Instead, supermarkets treat fruits and vegetables with a variety of chemicals for long-term storage.
Even so-called "local" apples are often stored for more than five months, and sometimes up to two years. According to research, an apple loses 60% of its vitamin C content within six weeks (if stored in the refrigerator).
What happens during long-term storage from a biological point of view? The sugar content increases, the vitamin content decreases.
Medium for winter storage of rhizomes and tubers
In autumn, growers dig up dahlia, calla and begonias tubers, canna rhizomes. They are stored in a cellar or refrigerator, sprinkled with dry fresh sawdust. Resinous components inhibit decay.
Farmers are zealous and creative people. They are capable of converting waste into income, especially when it comes to organic matter. As you can see, using pine sawdust or any other sawdust can be beneficial in the right hands.
