Olá Amigo. Essa propaganda foi feita pela Espiral que encerrou sua atividades no início dos anos 90. Portanto essa propaganda não pode ter sido feita nos anos 2000.

@@hidrosilomemoria2521 entao quer dizer que o jingle foi baseada nessa musica?

A Equipe Hidrosilo agradece o seu contato. Durante o período de germinação, mantendo o pote fechado para o gel não perder água, não é necessário rega. Somente depois que a plântula crescer mais que a altura do pote e precisar ficar aberto, que necessitamos regar, principalmente quando a camada superficial da areia ficar seca. Mas são regas esporádicas, já que o gel retém bastante a água, coisa que a areia sozinha na faz.

Olá. Essa canção foi composta pela Espiral produtora para mostrar essa coletânea de vídeos que ela produziu nos anos 70, 80 e 90. Não sei o nome da musica . Os vídeos integrais estão no canal. É só procurar.

Olá. Essa é uma cotanea. As propagandas inteiras da Espiral estão no canal. É só procurar.

Olá. Como esta escrito na descrição esse vídeo é uma coletânea de propagandas da Espiral. Os comerciais completos estão no canal. É só procurar.

The Hidrosilo team thanks you for contacting us. That's right. Sunlight degrades the cross-links that are responsible for the formation of the gel with water. Temperature does not affect this property of sodium polyacrylate and it is not suitable for use in applications that require exposure to sunlight, such as in agriculture. Sodium polyacrylate is for use in personal hygiene and not in agriculture. Hidrosilo superabsorbent polymer was developed not to be degraded by sunlight or UV radiation and is therefore suitable for use in agriculture. Hidrosilo gel can remain exposed to the sun for months or years without decomposing.

The Hidrosilo Team thanks you for contacting us. Impractical or not, we have to teach it correctly. What you cannot do is mix the superabsorbent polymer with NPK and apply them together to the soil. As do many farmers in Brazil. The salts present in NPK do not allow the polymer to swell. Thus, its use as a water reservoir in the ground lost its purpose. The planting gel is only used for the plant's placement in the soil. A liter of gel for a small plant is an ocean. For an adult plant it means nothing. Therefore, it only works at this stage. After a few months when the plant has developed roots and no longer needs the gel, you can use whatever fertilizer you want. Here in Brazil, when planting seedlings in coffee, eucalyptus and native trees, we do not recommend using fertilizers, as Hidrosílo already contains potassium and nitrogen. When necessary, just use a little super simple phosphate at the bottom of the pit, cover it with soil and place the plant, as in the case of planting coffee. We have excellent results using it this way. Using 1L of Hidrosil gel at 5g/L in the pit, it is possible to plant eucalyptus in dry periods and have a mortality rate of less than 1%, even without watering for 30 days.

@@hidrosilomemoria2521 thanks for the response. Lets say if the hydrogel already get in contact with the NPK, will it lose the absorbent ability? Or after sometimes it will recover its ability?

The Hidrosilo team thanks you for your question. Water-soluble fertilizers based on chlorides, nitrates, phosphates and sulphates of ammonium and potassium cations only reduce the swelling capacity of the polymer, but as soon as these salts are leached, the polymer swells again. But fertilizers based on calcium and magnesium salts such as calcium nitrate, calcium sulfate (gypsum), magnesium nitrate, react with polyacrylates to form insoluble calcium polyacrylate and magnesium polyacrylate respectively, which do not swell. This way the polymer no longer recovers its properties. Salts of copper, zinc, manganese, iron, cobalt used as micronutrients also form insoluble and rigid polyacrylates that do not swell. Urea is a nitrogen fertilizer that does not reduce the degree of swelling of polyacrylate. Another factor that greatly affects the degree of swelling of polyacrylates in superabsorbent polymers is sunlight on sodium polyacrylate used in personal hygiene. Sunlight, especially UV rays, irreversibly decomposes the cross-links of the polymer chain, which are responsible for the polymer's water absorption. Therefore, sodium polyacrylates should not be used in agriculture, as they were not developed to resist sunlight. We have a video on CZcams that shows this property.
