Why not advocate corn one-time fertilization

One-time fertilization of corn can save labor, but this has drawbacks, so it is generally not recommended one-time fertilization, because compared with base fertilizer, topdressing, easy to cause pre-mad or post-defermentation, yield and fertilizer utilization have declined. However, if there are mechanized sowing and fertilizing conditions, the fertilizer is applied to layers of different depths at the time of sowing and is separated from the seeds to meet the nutrient requirements of the crop at different stages of the crop, and high yields and high fertilizer efficiency have been obtained. Production practice confirmed.
