When the fertilizer is applied to the depth of the tillage layer, it is easily absorbed by the paddy field crop and the utilization of fertilizer is increased. There are three types of deep fertilization in paddy fields:
The ploughing field deeply drains the field water to near dryness before ploughing, and then evenly spreads the fertilizer on the field.
Ball fertilizer deep application This is a method of topdressing fertilizer. Fertilizer and fertilizer mud and water are made into ball fertilizer in a certain proportion. Each weight is about 100 grams. When top dressing, a ball fertilizer is inserted into the middle of every 4 seedlings. Depth 7 to 10 cm.
Deep liquid application This is another way of topdressing. Fertilizer or farmyard water is used as a fertilizer solution and then applied to the soil with a fertiliser. A depth of about 10 cm is appropriate.
