Abstract
Methods of forming a fertilizer composition having slow-release nitrogen compounds with a molten process are disclosed. The methods include mixing of a crystalline polyethylene wax with urea and formaldehyde to form a molten methylene urea mixture. The contents of the molten methylene urea mixture react to form slow-release nitrogen compounds. Fertilizer compositions formed of or including the slow-release nitrogen compounds are also disclosed.
