How to Apply Fertilizer Correctly
Practical field advice for Sugar Beet — knowing how to apply fertilizer matters as much as knowing how much.
What is the correct way to flood DAP for Sugar Beet?
Dissolve the DAP with a DAP solvent in a drum so it fully dissolves. Do NOT open the drum valve at the start of irrigation — wait until the water has covered about 25% of the plot (roughly 1–1.5 kanal in). Then open the valve. Close the drum valve about 10 minutes before you stop the water, so the last flow of water carries the dissolved fertilizer evenly to the far end of the field.
Should urea be flooded with irrigation water, or broadcast afterwards?
Do NOT flood urea. Flooding loses 40–50% of nitrogen through leaching (deep percolation) and denitrification (lost as gas). Instead, broadcast (chhatta) the urea 1–3 days after irrigation, when the soil is moist (tar-wattar condition). This gives 30%+ better absorption than flooding.
How can I distribute fertilizer evenly across the field?
Open the fertilizer drum valve only after irrigation water has already entered 1–1.5 kanal — opening it too early empties the drum before the far end is reached. If the field is not laser-leveled, divide one acre into 2–4 plots (kyare): 2 plots for heavy clay soils, 3–4 for loam, and fertigate each plot separately. Keep checking both the field and the drum during irrigation until you get a feel for the timing.
When should phosphorus and potash be applied?
Phosphorus (P₂O₅) and potash (K₂O) are best applied at sowing as a basal dose, placed in the seedbed. If you missed it at sowing, dissolve the fertilizer (use a DAP solvent for DAP) and flood it at the first or second irrigation — flooding is far more effective than broadcasting for phosphorus and potash at that stage.
유기 비료 옵션
잘 썩은 농장의 거름, 퇴비 또는 해충은 Sugar Beet의 기본 토양 개량제로 사용할 수 있습니다. 토양 구조를 형성하고 계절에 따라 천천히 영양분을 방출합니다. 유기농 영양소 함량은 공급원에 따라 다르기 때문에 작물과 지역에 맞게 계산된 광물질 비료로 정확한 영양소 요구량을 보충하세요.
