NPK 15-5-20+TE – Potassium-Rich Rainy Season Fertilizer with Added Micronutrients

Prolonged rain, high humidity, lack of sunlight and erratic weather can affect crop growth, especially during flowering, panicle initiation, grain filling and fruit development. Viet Nga Fertilizer’s NPK 15-5-20+TE, with a formula rich in potassium (20%) combined with NPK and added micronutrients, is intended for use in the rainy season, helping supply suitable nutrition to plants at important growth stages.

Why choose the right fertilizer for crops in the rainy season?

The rainy season brings the water crops need; however, prolonged rain, high humidity, reduced sunlight hours and erratic weather can also affect photosynthesis and plant growth. In particular, when plants enter important stages such as flower bud differentiation, flowering, panicle initiation, grain formation or fruit development, their nutrient needs must be met in line with each growth stage.

Besides nitrogen and phosphorus, potassium and micronutrients are nutrients that deserve attention when choosing fertilizer for crops in the rainy season. Supplying nutrition that matches the plant’s needs and each growth stage helps plants maintain their physiological activity and grow more steadily when the weather fluctuates.

NPK 15-5-20+TE – A nutrient formula suited to the rainy season

Viet Nga Fertilizer’s NPK 15-5-20+TE is formulated with 15% total nitrogen (N), 5% available phosphate (P₂O₅), 20% available potash (K₂O), Fe 50 ppm and added Mg, Cu, Zn, Mn, B… In the NPK 15-5-20+TE formula, the figures 15-5-20 represent the proportions of total nitrogen (N), available phosphate (P₂O₅) and available potash (K₂O), respectively. The 20% potassium content is the highlight of the formula, combined with nitrogen, phosphorus and micronutrients to supply nutrition to crops.

With a higher proportion of potassium than nitrogen and phosphorus, NPK 15-5-20+TE is intended for stages when plants have a high potassium demand, such as preparing to flower and fruit development; for rice, the panicle initiation and grain filling stages. The combination of NPK and micronutrients helps supply nutrition that matches the plant’s needs during important growth stages.

How does NPK 15-5-20+TE support crops in the rainy season?

What stands out about NPK 15-5-20+TE in the rainy season is its 20% potassium content combined with macronutrients and micronutrients. Each nutrient group plays a different role, helping meet the plant’s needs during important growth stages.

Rich in potassium (20%) – Supports nutrient transport and strengthens plants

The 20% available potash (K₂O) content is one of the highlights of NPK 15-5-20+TE. Potassium supports the transport and accumulation of nutrients within the plant while helping to strengthen the plant. This role is especially important when plants enter the reproductive stage, helping meet the need to transport nutrients to developing organs such as flowers, grains and fruit.

Added micronutrients – Support photosynthesis in low-sunlight conditions

Micronutrients take part in many physiological processes in the plant, including photosynthesis, helping plants sustain growth when rainy-season weather is less favorable.

Helps improve resilience under rain and high humidity

Prolonged rain, high humidity and erratic weather can affect crop growth. Supplying suitable nutrition at each stage helps plants maintain their vigor and adapt better to rainy-season growing conditions. With a potassium-rich formula combined with NPK and micronutrients, NPK 15-5-20+TE helps supply suitable nutrition to plants during periods of fluctuating weather.

Which crops is NPK 15-5-20+TE suitable for?

Viet Nga Fertilizer’s NPK 15-5-20+TE is suitable for many crop groups such as rice, industrial crops, fruit trees and vegetables. For rice, the product is intended for the panicle initiation and grain filling stages, when the plant’s potassium demand increases for grain formation and development.

For industrial crops and fruit trees, NPK 15-5-20+TE is suitable at the pre-flowering and fruit development stages. The product can also be used for vegetables depending on nutrient needs and growth stage. Depending on the crop, variety, soil characteristics and actual growing conditions, farmers should choose an appropriate application rate and follow the product’s usage instructions.

Some notes when using NPK 15-5-20+TE in the rainy season

For NPK 15-5-20+TE to be effective, farmers should base the application rate on the crop type, growth stage, soil characteristics and the actual condition of the plants. The product is intended for the pre-flowering and fruit development stages; for rice, the panicle initiation and grain filling stages. The rate should be adjusted to the land, crop variety and actual growing conditions, while following the product’s usage instructions.

In the rainy season, the timing of fertilizer application also needs attention. Farmers should monitor the weather closely and avoid applying fertilizer when heavy rain is forecast or when fields and orchards are waterlogged or poorly drained, to limit fertilizer leaching and its impact on nutrient uptake. In areas that often receive heavy rain, pay attention to drainage systems and monitor the plants after rain to adjust care accordingly.

In addition, do not rely on a single fixed fertilizer formula for the entire season. A plant’s nutrient needs change with each stage, so observe plant vigor, leaf color, growth, flowering and grain or fruit development before supplying nutrients. Fertilization should be combined with appropriate care and field management practices so that plants can absorb and use nutrients more effectively.

For each crop and specific growing condition, farmers should follow the instructions on the packaging or consult the recommendations of Viet Nga Fertilizer’s technical team to determine the right timing and rate, avoiding under- or over-fertilization.

Viet Nga Fertilizer’s NPK 15-5-20+TE, with 20% potassium combined with NPK and added micronutrients, is a suitable nutrition choice for many crop groups in the rainy season, especially at the pre-flowering and fruit development stages; for rice, the panicle initiation and grain filling stages. To get the most from the fertilizer, farmers should apply it at the right stage and choose a rate that suits the crop, soil conditions and actual weather.
