Principles of application
Sulfoammophos NРK+ 20:20:0+14S is used as a basal, starter and side/top dress fertilizer. It is the most suitable for basal application under spring crops. Autumn application for spring sowing does not cause significant nitrogen losses.
Fertilizer can be applied at sowing to winter and spring crops. Its application does not lead to high concentration of salt in nutrition elements.
Side dressing is the most effective for arable crops. Top dressing is less effective. It is better to top dress close-growing crops in the early phases of the growing season when water availability is sufficient and air temperature is from 10 to 20 degrees. Under such conditions water-soluble phosphorus moves into underdeveloped root system area along with soil solution and is effectively absorbed by plants. Ammonium nitrogen transforms into nitrate nitrogen and becomes movable.
