In the rainy season, the storage of chemical fertilizers is mainly the problem of moisture absorption and agglomeration of chemical fertilizers. After agglomeration, the commercial properties of the fertilizer deteriorated, making it difficult to achieve mechanical application. Farmers are reluctant to buy, even if the price is reduced, the farmers take it back, increasing the labor of broken and agglomerated, and manpower fertilization is difficult, and uneven application will burn the seedlings. Under normal circumstances, there are three ways to store fertilizer: warehouse storage, storage shed and open field stacking.
Â
In the rainy season, warehouse storage should generally be the mainstay. The inside of the library should be ventilated and cooled, and dry and protected from rain and moisture. There are two ways to store fertilizer in the warehouse: bulk storage and bag storage. For nitrogenous fertilizers with strong hygroscopicity, such as ammonium nitrate, bags should be used to avoid large piles of storage. Other varieties of nitrogen fertilizer and phosphorus and potassium fertilizers should not be stored for too long. In the rainy season, bags are generally required. The package should be double-layered and lined with plastic bags to wrap the woven bag. Whether it is bulk or bag storage, in order to avoid agglomeration, the storage pressure should be reduced, and the height of the pile and the pile should be controlled, such as a large bag of 25 - 40 kg, with a pile of 20 bags at a moderate height.

Choose the storage method of the shed to be extra careful during the rainy season. The location of the shed should be high, dry and ventilated, and the roof should be protected from rain.
Â
In the rainy season, open field stacking is not allowed. Even if it is temporarily stacked, it is necessary to select a place with high ground, dry and ventilated, and take measures such as covering the cloth to prevent rain. Experts suggest that hygroscopicity is the bane of chemical fertilizer agglomeration; the key to chemical fertilizer storage during hot and rainy seasons is moisture protection.
Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. An Achromatic Lens, which is often designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses.
Realpoo Optics offer doublet achromatic lens, triple achromatic lens, square achromatic lens, micro achromatic lens, edge blackening achromatic lens etc.
