topbemesting

Topbemesting, also known as top dressing, is the practice of applying fertilizer to the soil surface around growing plants. It is typically done after planting or during the crop’s active growth to supply nutrients close to the root zone without mixing the fertilizer deeply into the soil. This method complements basal or incorporated fertilization.

Fertilizers used for topbemesting can be granular or compacted into slow‑release forms, and they may be inorganic compounds (such as NPK blends) or organic materials (such as compost, manure, or decomposed mulch). Granular products are spread evenly over the soil surface with a spreader and, if needed, lightly incorporated or watered in to improve availability. Liquid fertilizers can be applied through irrigation (fertigation) for uniform distribution. Organic topdressing often improves soil structure and microbial activity.

Timing and placement are important. In lawns, topbemesting is commonly done in spring or autumn to support growth and color, while avoiding drought, heat, or frost conditions. In horticultural crops, applications follow growth stages when nutrient uptake is highest. It is important to avoid applying fertilizer before heavy rainfall, on frozen ground, or when the root zone is saturated, to prevent leaching or root burn.

Nutrient needs depend on the crop, soil fertility, and tissue or soil tests. Over-application can cause fertilizer burn and environmental pollution, while under-application limits growth. Controlled‑release products and soil testing help optimize efficiency and reduce risks.
