How long does esn stay bad

ESN will give your crops the right amount of nitrogen it needs, at the right time. Learn more about how ESN works here. To hear from more growers across North America, click here. How long have you been using ESN? Tweet us SmartNitrogen and let us know! Three I words are key to managing urea: Incorporation, injection and irrigation.

If you don't incorporate dry urea with tillage, inject it beneath the surface residue or irrigate it in, you'd better hope for rain within a few days of application. Other options are treating urea with Agrotain a urease inhibitor or using ESN, a controlled-release urea.

Ammonia volatilization poses the first risk for losing urea nitrogen. When urea is applied, an enzyme in soil and plant residue called urease quickly converts the urea into ammonia N.

If this conversion occurs beneath the soil surface, the ammonia is converted to ammonium nitrogen and bound to soil particles. That's a good thing. However, if the urea is converted to ammonia on the soil surface or on residue, as would be the case in a no-till system, ammonia gas can escape into the atmosphere. That process is called ammonia volatilization, and it's a bad thing. Because of all the interacting factors, it's impossible to predict exactly how much nitrogen will be lost when urea is applied to the soil surface.

Soil temperature, soil pH, soil texture, soil moisture, the amount of time between application and a significant rain and, of course, the amount of residue, all play a role.

Soil pH can make a big difference also, according to Rehm. After just two days on the surface, five percent of the urea can be volatilized as ammonia at a pH of 7. Never apply urea to fields that have recently had lime applied. Less urea is lost from dry soil surfaces or dry residue. We teamed up with UNESCO to safeguard the futures of education by sparking a dialogue about the priorities and problems of the Erasmus generation. In order to grasp a better understanding of the barriers and enablers of mobility for students, and to ensure more equitable access for all students regardless of background, we launched the Social Inclusion and Engagement in Mobility survey.

We understood that despite their low numbers in participation, a high number of students with disabilities want to go abroad, but inclusion is not sufficiently present in mobility strategies. Join us in January for the launch! As such, we participated in the EU Youth Conference and voiced the thoughts, concerns and opinions of the Erasmus generation. During the Third European Education Summit , we addressed the gender dimension in education.

Erasmus Student Network was represented at the Third European Youth Convention , which is the central platform for discussing the latest developments in youth work practice and youth policy in Europe. During the weekend of growing enthusiasm, ESN invested in its volunteers with the promise to create more and better Erasmus in Schools activities for the Network and Society. During the first-ever General Assembly of Erasmus Student Network , we gathered 42 National Organisation representatives online and discussed the future of the network.

One of the positive outcomes of the Assembly was the decision to remove the borders limitation from our Statutes and open ourselves to the possibility to have ESN member organisations outside of the EHEA, starting with the Southern Mediterranean region. Like this, students everywhere will have the possibility to participate in ESN activities. The ranking is based on the opinion of young professionals who have rated their job experiences in Brussels.
