This video explains best practices for applying nitrogen fertilizer to grass meadows.
Forms of nitrogen fertilizers
Forms most absorbed by plants:
Nitrate (NO3-)
Ammonium (NH4+)
Slow release forms:
Protected urea
Slow release ammonium sulphate
Factors affecting the effectiveness of nitrogen fertilizers
Presence of legumes: Legumes fix atmospheric nitrogen, thus reducing the need for nitrogen fertilizers.
Soil type: Clay soils retain nitrogen better than sandy soils.
Quantity of organic matter: Organic matter helps to retain nitrogen in the soil.
Climatic conditions: Nitrogen losses by leaching are greater in case of heavy rains.
Recommendations for the application of nitrogen fertilizers
Divide the doses: Apply the fertilizer in several times rather than all at once.
Avoid application during periods of heavy rains: This reduces leaching losses.
Incorporate fertilizer into the soil: This makes it more accessible to plants.
Take into account the needs of the plants: The quantity of nitrogen fertilizer to be applied depends on the type of plant and its stage of development.
Monitor yields and adjust doses accordingly: It is important to monitor the evolution of yields to ensure that nitrogen fertilizer doses are adequate.
Conclusion
Applying nitrogen fertilizers to grass meadows can be an effective practice for increasing yields. However, it is important to follow good practices to maximize fertilizer efficiency and minimize environmental impacts.
