How should fertilizer be applied when growing cotton? Here are the methods
When growing cotton, you can refer to the following fertilization methods:
1. Chemical fertilizers used as base fertilizer can be spread on the soil surface before plowing, and turned into the soil together with farmyard manure. This way, the fertilizer is applied deep and evenly, nutrient loss is small, and it can be absorbed and used by the cotton roots distributed throughout the soil.
2. Install a fertilizer applicator on the seeder and apply fertilizer at the same time as sowing. Fertilizer is applied first, placed between two rows of cotton, at a depth of 8 to 10 cm, and then the seeds are sown behind. This saves labor, concentrates the fertilizer, reduces nutrient loss, and allows the seedlings to use it quickly.
3. Before sowing, design the row spacing and number of rows well, insert markers, first apply one row of fertilizer between the two reserved cotton rows at a depth of more than 10 cm, and then sow. This way, the fertilizer is applied deep.
4. If rotary tillage is used instead of plowing, fertilizer can also be spread on the soil surface before rotary tillage, but try to make the rotary tillage reach a depth of about 15 cm. Shallow rotary tillage after fertilization is the worst mistake, as it leaves most of the fertilizer in the upper soil layer, causing great nutrient loss.
Whether fertilizer is applied before plowing or before rotary tillage, irrigation can be carried out after plowing or rotary tillage to build soil moisture. Calculated at 60 to 80 cubic m of irrigation water per mu, the water depth is 9 to 12 cm. The fertilizer will not leach into the ground with the water, but will be retained in the shallow soil layer on the surface, available for absorption and use by the cotton root system.
Applying base fertilizer is a key high-yield measure for cotton, related to cotton yield and the profitability of cotton growing, so it must be done well.
