1、Appropriate Amounts of Fertilizer and Phosphate for 9 Mu of Land

For most crops, approximately 50–100 kg of nitrogen fertilizer, 10–20 kg of phosphate fertilizer, and 10–20 kg of potassium fertilizer per mu are required. these values vary depending on specific crop demands.

How To Calculate Fertilizer Application Rate For Any Crop

To calculate fertilizer application rate, first determine how much nitrogen, phosphorus, and potassium your soil contains. You need to do a soil test by collecting soil samples from different parts of your field and sending them to a laboratory for analysis.

Fertilizer Types and Calculating Application Rates

Phosphate and K 2 O can be land-applied at any time, but normally it is more cost-effective to apply at the same time as N. However, N is more mobile than P 2 O 5 and K 2 O in the soil and should be applied as closely as possible to the time of crop uptake.

How Much Phosphate Fertilizer Is Appropriate for Paddy Fields?

The appropriate amount of phosphate fertilizer to apply in paddy fields depends on various factors, including soil type, crop requirements, climatic conditions, and fertilization objectives.

In agricultural production, phosphate fertilizer plays a critical role in improving soil fertility and promoting crop growth. The appropriate amount of phosphate fertilizer for one mu (approx. 0.067 hectares) of dry land depends on factors such as soil conditions, crop requirements, and climatic conditions. Below are some recommendations:

1. Soil Testing: Before applying fertilizer, conduct soil tests to determine pH, organic matter content, nutrient levels (including phosphorus), and soil texture. This information is essential for determining the correct phosphate fertilizer dosage.

2. Crop Requirements: Different crops have varying phosphorus needs. Leguminous crops like soybeans and peanuts typically require more phosphorus, while gramineous crops like wheat and corn need relatively less. Adjust phosphate fertilizer amounts based on the specific crop type.

3. Climatic Conditions: Climate affects phosphate usage. In arid regions with limited rainfall, slow crop growth reduces phosphorus demand. In humid, rainy areas, faster crop growth increases the need for phosphorus.

4. Soil Texture: Soil type influences phosphate application. Clayey soils retain water and nutrients well but fix phosphorus, making it less accessible to crops. Sandy soils drain quickly but risk leaching phosphorus. Choose phosphate products suited to soil texture.

5. Application Methods: Phosphate can be applied via banding, hole placement, or trench application. Banding and hole placement distribute phosphorus evenly, aiding absorption, while trench application improves soil aeration for root growth.

6. Timing: Apply phosphate during early or mid-growth stages when crops demand it most. Late-stage application may negatively impact yield and quality.

7. Dosage: There is no fixed standard for phosphate use per mu. A general guideline is 5–10 kg of diammonium phosphate (DAP, containing ~50% phosphorus) per mu. Adjust based on field-specific conditions and experience.

8. Fertilization Strategies: Combine phosphate with organic fertilizers (e.g., chicken manure, cow dung) to enhance efficiency. Compound fertilizers (e.g., phosphorus-potassium blends) can also meet dual nutrient needs.

9. Precautions: Avoid overapplying phosphate to prevent soil acidification or salinization. Do not apply directly near crop roots, as this may disrupt normal growth.

the appropriate phosphate dose for dry land depends on soil, crops, and climate. Follow scientific principles, optimize usage rates, and prioritize crop health to maximize agricultural productivity.
