To replace urea with urea ammonium nitrate solution, the fertilization structure should be adjusted first, and the base fertilizer should be applied as deep as possible to maintain the fertilizer effect for a long time. Generally, potato cultivation requires about 20 kg of urea, and the cost is about 30 yuan. After years of experiments and demonstrations, if the application of urea ammonium nitrate solution only needs about 5 kg, it can meet the growth demand of potatoes, and the cost is about 25 yuan, so the planting cost is increased. In the application of liquid fertilizer, we must pay attention to a small number of times. In the early stage of potato growth, we should increase the nitrogen fertilizer. After the bud, we should reduce the amount of nitrogen fertilizer, increase the supply of potassium fertilizer, boron fertilizer and zinc fertilizer, and achieve nutrient balance to avoid the spur of the upper part of the flower. The lower part of the "sweet potato". Disclaimer: Some articles on this website are transferred from the Internet.

Potato urea and some ammonium nitrate solution
The urea ammonium nitrate solution is prepared from urea, ammonium nitrate and water. It combines three kinds of nitrogen sources and can exert various nitrogen source advantages. Production practice also proves that the effect of applying urea ammonium nitrate solution on planting potatoes is significantly better than that of single application of urea.
