The proportion of NPK fertilizer in wheat

The situation is not the same everywhere, fertilization is not one, it is recommended to fertilize as follows

High-yield fields need to “control nitrogen, stabilize phosphorus, and increase potassium”; middle-quality fields must “stabilize nitrogen and increase phosphorus”; low-yield fields must “add nitrogen and increase phosphorus”.

The application rate of fertilizer for mu is roughly:

High-yielding fields usually have 50-70 kg of standard nitrogen fertilizer, 40-50 kg of standard phosphate fertilizer, 10 kg of potash fertilizer, and 1.5 kg of zinc fertilizer.

Mid-level fields generally apply 50-60 kg of standard nitrogen fertilizer, 50 kg of standard phosphate fertilizer, and 5 to 10 kg of potash fertilizer;

Low-yielding fields generally use 40-50 kg of standard nitrogen fertilizer and 50 kg of standard phosphate fertilizer.

Apply all organic fertilizer, phosphate fertilizer, and potassium fertilizer. 50% of nitrogen fertilizer is applied, and 50% is used for fertilizer during jointing stage. We must vigorously promote the deep application of chemical fertilizers and resolutely put an end to surface dissemination.
