Development and evaluation of nitrogen (liquid Urea) applicator for straw mulched no-till wheat
2013
unpublished
The broadcasting of urea under high straw no-till farming often exhibit suppressed yields because of lesser nitrogen availability due to slower soil mineralization and greater N immobilization, de-nitrification and ammonia volatilization. Prior to development of nitrogen (liquid urea) applicator, appropriate machines were not available for application of urea into the soil surface in a directly sown high straw mulched wheat crop. To solve the problems of urea application in high straw no-till
