Homemade cotton formula fertilizer

Formula fertilization of cotton, also known as balanced fertilization of cotton, is based on the characteristics of the cotton's fertility and fertilizer requirements according to the local soil nutrient status and the requirements for the level of cotton production, applying different types and different amounts of fertilizer, so that the effective nutrients in the soil Balanced and meet the requirements of cotton fertilizer. Through years of research and agricultural extension departments' practical experience in agricultural scientific research units, the ratio of nitrogen, phosphorus, and potassium in cotton fields is generally 1:0.8:0.6. If zinc, boron, and other trace elements can be applied at the same time as required, the effect is even greater. good.
In order to facilitate the operations of cotton farmers, special fertilizer manufacturers in cotton production will optimize the configuration of the combination of nitrogen, phosphorus, potassium and trace elements according to the growth and development needs of cotton. As long as farmers rely on their own production requirements, scientific methods of fertilization and the amount of fertilizer can be achieved. The intended purpose. To target 100-125 kilograms of cotton (lint) per mu, the content of organic matter in cotton fields should be 1%-1.2%, while organic fertilizers should be applied at 4000-5000 kg, 15 kg of pure nitrogen, 12 kg of pure phosphorus, and 9 kg of pure potassium. Add 1.2 kg of zinc sulfate and 0.5-1 kg of boron. If it is required to produce 75 kilograms of cotton (lint) per acre of cotton field, the organic matter in the cotton field shall be 0.8%-1%, the pure nitrogen is 7.5 kilograms, the pure phosphorus is 6 kilograms, and the pure potassium is 4.5 kilograms, plus zinc sulfate and borax 0.5 -1 kg. In order to increase the effective utilization of fertilizers, fertilization in cotton fields should be emphasized. Fertilization methods generally require the combination of organic matter, phosphorus and potassium fertilizers, trace elements, and 1/3 of nitrogen fertilizer to be used as a base fertilizer, combined with site preparation for furrow application, and the remaining 2/3 nitrogen fertilizers. Watering, topdressing at the budding or early flowering stage of cotton.

A Petri Dish (alternatively known as a Petri plate or cell-culture dish) is a shallow transparent lidded dish that biologists use to culture cells[1][2], such as bacteria, or small mosses.[3] It is the most common type of culture plate.

The container is named after the German bacteriologist Julius Richard Petri.[4][5]

Penicillin, the first antibiotic, was discovered in 1929 when Alexander Fleming noticed that mold that had contamined a bacterial culture in a Petri dish had killed the bacteria all around it.

The Petri dish is one of the most common items in biology laboratories, and has entered popular culture. The term is often written in lower case, especially in non-technical literature
