The Secret to Massive Rice Yields: Big Panicles & Heavy Grains with Parich Ton-Mai

Parich Ton-Mai is the advanced agricultural solution that maximizes rice tillering and grain weight using superior American coating technology.

Farmers, stop settling for light grains and empty husks. Parich Fertilizer brings you the modern standard for rice farming—whether broadcast or transplanted—guaranteeing heavy harvests and higher profits.

Why Smart Rice Farmers Switch to Parich

Standard fertilizers evaporate and fade away. Parich stays in the soil, feeding your crop exactly what it needs, when it needs it.

Key Benefits of Parich Ton-Mai

Prevents nitrogen volatilization. Your rice gets a steady food supply, resulting in larger panicles, fully filled grains, and superior weight.
Supercharges root development. Stronger roots mean faster establishment and rice plants that stand tall against wind and rain (reduced lodging).
Zero soil, zero waste. You get 100% pure, concentrated nutrients in every single bag.
High Sulfur (S) and Magnesium (Mg) content keeps leaves green and upright, maximizing energy production for bigger grains.
Promotes vigorous branching (tillering), creating a dense, productive field ready for a massive harvest.

Parich Pro Tip:

The secret to “Full Grains, No Empties” lies in the Flag Leaf. Ordinary fertilizers run out of steam too early, causing the flag leaf to yellow and stop feeding the grain. Parich keeps the flag leaf green and active longer, allowing the plant to pump starch into the grain right up until harvest. That means heavy weight in every sack!

Frequently Asked Questions (FAQ)

Q: Are fertilizer formulas for Clay Soil Rice and Sandy Soil Rice the same?

A: No, they are different. Sandy soil has lower water and nutrient retention capabilities and is often low in Potassium (K). Therefore, sandy soil requires a fertilizer containing all 3 primary nutrients plus additional secondary nutrients for high-quality yields. Clay soil retains nutrients better; in some areas where soil analysis shows high levels of specific nutrients, you may reduce or omit that specific nutrient.

Q: Which fertilizer formula can fix saline (salty) soil?

A: Chemical fertilizer cannot directly fix saline soil. Correcting saline soil requires other methods, such as applying Gypsum (Calcium Sulfate), plowing in green manure, or draining the salty water from the field.

Q: Which fertilizer formula gives the best rice weight?

A: Fertilizers capable of providing high Potassium (K) during the Booting to Heading stages will help achieve the best weight. Potassium aids in synthesizing starch and transporting it to accumulate in the rice grains.

Q: Are fertilizer formulas for In-Season Rice (Na-Pi) and Off-Season Rice (Na-Prang) the same?

A: It depends on the soil potential and the rice variety planted. Off-season rice often has better water management and allows for more precise fertilizer control, so nutrient requirements might differ from In-Season rice.

Q: Does applying organic fertilizer cause new types of weeds to appear in the field?

A: It is possible if the raw materials used to make the organic fertilizer (such as animal manure) have not undergone a complete fermentation process, leaving weed seeds contaminated inside which then germinate in the field. However, Parich Organic Fertilizer undergoes a process to manage contaminated weed seeds before production, ensuring that Parich Organic Fertilizer does not introduce weeds to your field.

Q: Does rice fertilizer float on water?

A: General chemical fertilizers or rice fertilizers do not float. They have a higher density than water and will sink.
