1、What Fertilizer Is Used For Rapeseed

Winter oilseed rape requires well-absorbed phosphorus and potassium, ideally from complex fertilizers for stubble management. Additionally, foliar applications of boron, manganese, and molybdenum are recommended, followed by copper, zinc, and iron as needed.

2、Comparison of phosphorus application on crop yield and soil phosphorus

Compared to the P0 treatment, on average, the P60 and P120 treatments increased rapeseed yield by 305.4 % and 460.2 %, respectively, and wheat yield by 76.8 % and 129.3 %, respectively. The rice yield increased by 46.3–48.3 % and 51.3–54.5 % in the RR and W R rotation, respectively.

3、Comparative Effect of Different Phosphatic Fertilizers on Growth of

An experiment was conducted to investigate the comparative effect of phosphatic fertilizers, viz. single super phosphate (SSP), di-ammonium phosphate (DAP) and triple superphosphate (TSP), on the growth of rapeseed.

4、Effect of phosphorus fertilizer on growth and yield of rapeseed

Phosphorus fertilizer is very useful and effective for the growth and strengthening of rapeseed plants, playing a key role in increasing rapeseed oil production and having many...

Fertilization of rapeseed

Particularly important nutrients responsible for the proper growth and development of rapeseed are contained in Fosfan fertilizers: phosphorus, potassium, calcium, magnesium, sulfur, boron, molybdenum and nitrogen.

Rapeseed phosphorus is suitable for early application

Early application of phosphate fertilizer can increase the concentration of plant cell fluid, enhance cold resistance, resist frost damage, and ensure that rapeseed can be safely wintered.

When fertile cultivation is most suitable for fertilization

Therefore, rapeseed must be applied with sufficient phosphate fertilizer before the 5 leaves of the seedlings. The moss flowering period is the maximum efficiency period of rapeseed nutrition, and the fertilizer content accounts for the largest proportion in the whole life.

Optimal phosphorus management strategies to enhance crop productivity

Optimal P managements are the equivalent of 16.0–38.3 kg P 2 O 5 hm −2 of P fertilizer. High P fertility soil has sustainable productivity in the rapeseed–rice rotation. Optimal phosphorus (P) managements can improve the crop yield without reducing soil P supply capacity over the long term.

The application of rapeseed phosphate fertilizer should be early

Early application of phosphate fertilizer can increase the concentration of plant cell fluid, enhance cold resistance, resist frost damage, help ensure the safe wintering of rapeseed, promote the early growth period, and increase the oil content of rapeseed by 0.5% to 2.4%.

Effect of Different Phosphate Fertilizer Usage on Yield and Quality of

The results showed that the yield, quality and planting economic benefit of rapeseed could be improved by applying appropriate amount of phosphorus fertilizer. Considering all factors, 90 kg/hm~2 of phosphorus fertilizer was recommended in Fujia Town of Hui County.

Choosing the appropriate phosphate fertilizer is crucial for promoting healthy growth and increasing yields in rapeseed cultivation. Phosphorus is an essential element for plant development, participating in key physiological processes such as cell division, tissue formation, energy conversion, and hormone synthesis. Rational application of phosphate fertilizers can significantly enhance stress resistance, improve quality, and boost productivity. Below is a detailed introduction to several commonly used phosphate fertilizers, along with planting recommendations.

1. Diammonium Phosphate (DAP)

Chemical Properties: DAP is a nitrogen-phosphorus compound fertilizer containing 21% N-P₂O₅-K₂O. It provides substantial phosphorus, moderate nitrogen, and potassium, suitable for various crops, including rapeseed.

Effectiveness: DAP is rapidly absorbed by plants, promoting root development and overall growth. It enhances leaf greenness and photosynthetic efficiency.

Application Recommendations: Apply as a base fertilizer before or immediately after sowing to ensure phosphorus supply throughout the growing season. Adjust dosage based on soil tests and growth stages to avoid root burning from overapplication.

Precautions: DAP may compete with calcium ions in the soil, reducing their availability. Combine with other fertilizers or use slow-release formulations to minimize this effect.

2. Superphosphate (Ca(H₂PO₄)₂ + CaSO₄)

Chemical Properties: Superphosphate is a high-phosphorus fertilizer containing P₂O₅, along with calcium (Ca) and sulfur (S). It is granular and water-soluble.

Effectiveness: Ideal for acidic soils, as it neutralizes excess acidity. Its high phosphorus content meets rapeseed’s nutritional demands at different stages.

Application Recommendations: Use as a topdressing fertilizer during early growth or peak periods. Spread evenly to avoid direct contact with roots, which may cause burns.

Precautions: Excessive use may lead to soil compaction due to reactions with calcium. Conduct soil tests before application to prevent negative impacts.

3. Triple Superphosphate (TSP)

Chemical Properties: TSP is a high-concentration phosphate fertilizer (>46% P₂O₅), primarily used to accelerate plant growth under drought conditions.

Effectiveness: Provides rapid phosphorus release, supporting rapeseed’s rapid growth phases. Suitable for phosphorus-demanding crops like rapeseed.

Application Recommendations: Apply during early or mid-growth stages for sustained phosphorus supply. Dilute according to product guidelines to avoid concentration-induced damage.

Precautions: Overuse may lead to phosphorus accumulation in soil, harming long-term soil health. Use cautiously and combine with soil management practices.

4. Monocalcium Phosphate (Ca(H₂PO₄)₂)

Chemical Properties: This white, powdered fertilizer contains high phosphorus and calcium. It is highly soluble and stable, suitable for base or topdressing applications.

Effectiveness: Maintains balanced nutrition in rapeseed and improves soil pH buffering capacity.

Application Recommendations: Use throughout all growth stages. Avoid mixing with alkaline substances to prevent compatibility issues.

Precautions: May react with certain pesticides. Store in dry conditions to prevent caking. Ensure compatibility with soil types.

When selecting and applying phosphate fertilizers, consider rapeseed’s growth stage, soil conditions, and climate. Optimal phosphorus ratios and timely application are critical for maximizing yield and quality. Always follow usage guidelines and combine with soil testing to ensure sustainable benefits.
