Global Fertilizer Day happens every year on October 13th. That Day helps to recall the important part that Fertilizer plays in the feeding of the whole world. The picked date marks the moment when Fritz Haber received a patent for the chemical mixing of ammonia from its basic elements, namely October 13th 1908.
That discovery one knows as the Haber-Bosch process, that lays the base for the Green Revolution. One counts it among the most remarkable inventions of history because it ensures food for almost half of the world population.
Global Fertilizer Day and Why Fertilizer Is Important
Every year the Fertilizer sector marks that date to strengthen attention to the central place of Fertilizer in the world security of food and in the growth of economies. Help of Fertilizer feeds the planet in responsible, efficient and lasting mode. On that occasion one put in focus the science, the workers and the teamwork, that backs the present state of farming.
Recently one organised a campaign for the Global Fertilizer Day with the motto „Feed Life”. It intended to show the key input of the European Fertilizer branch to the feeding of crops, ranchers, folks, the European economy and to a future with lasting activity. Moreover, IFA issued a series of short videos, that shows how specialists in various tasks help fede the world and advance green farming daily.
Also companies like Nutrien join in the event. Workers in the sections of Nutrien for nitrogen, phosphate and potash feel pride because of their role in support of growers and in assurance of food for the growing population of the world. In Canada the group for Fertilizer prepared a guide for social nets, that helps promote the festival until October 13th; it carries offers about content and key ideas.
Moreover, although it deals about a global event, the usage of Fertilizer itself posts many practical tips, that deserve to note. Not always does it help to apply fast release of food on a meadow, because that risks to hurt the leaves instead of bringing them to the soil. Slowly releasing kind works well, if one gives it every four to six weeks.
Liquid Fertilizer and those slow give better control about that, that food arrives too the plant. According to the intended part (roots), leaves, flowers or fruits, a bit different mixes prove best.
In pot plants and house plants, one should give food each two to four weeks during the active growth in spring and summer; that is good habit. In autumn and winter one reduces or halts the use, which has sense. Keeping Fertilizer during the sleepy period usually is useless expense, because most plants will not absorb the stuff then.
In places like New Jersey, laws themselves ban the use of Fertilizer with nitrogen or phosphorus after November 15th and before March 1st.
Early in the morning applying Fertilizer leaves time to spread it well and so that the sun does not dry the surface too quickly. On days above 90 degrees one does smart, if one waits for a cooler moment for the usage. For meadows also seasonal dates work as a good plan for uses.
Memorial Day, Labour Day and around Thanksgiving. Thatsuffices for most of them.
