Clean vegetables and fruits thanks to "pure fertilizer"

Over the past 3 years, Ms. Bui Thi Khanh Hoa, Director of Dak Nong Clean Agriculture Joint Stock Company, has applied new techniques to take care of vegetables and fruits grown in 1,300m2 ^of greenhouses.

Ms. Bui Thi Khanh Hoa, Director of Dak Nong Clean Agriculture Joint Stock Company, uses silkworm manure to produce organic agricultural products to increase product value.

Currently, she is growing 1.5 hectares of super-leaf mulberry to raise silkworms. According to Ms. Hoa, growing mulberry to raise silkworms brings double benefits. The entire mulberry area is cared for organically by her, thereby achieving good productivity and cocoon quality, each month she collects 3-4 boxes of cocoons.

Each cocoon box weighs 18 - 25kg, and she sells it for about 20 million VND. In total, each month, Ms. Hoa earns about 70 - 80 million VND from selling cocoons.

What is special is that Ms. Hoa uses all the silkworm manure to make organic fertilizer to grow vegetables and fruits in ^a 1,300m2 greenhouse. Ms. Hoa said that 1 box of silkworms gives 300kg of fertilizer, each month she harvests over 100kg of fertilizer.

All plants in the greenhouse are taken care of by Ms. Bui Thi Khanh Hoa using silkworm manure.

Ms. Hoa shared: “Silkworm manure can be processed by composting after about 45 days. All the silkworm manure after being cleaned is mixed with 50% coconut fiber and used to fertilize plants. This type of organic fertilizer is very good for plants, ensuring product quality and safety.”

Ms. Hoa grows ^1,300m2 of greenhouse plants including: fruit tomatoes, fruit peppers, strawberries, baby watermelons, cantaloupes and vegetables. All are cared for organically, ensuring food safety.

“I understand that organic agricultural production techniques are very suitable. This is a type of “pure fertilizer”. If mulberry leaves contain pesticides or toxic chemicals, silkworms will die when they eat them. Therefore, mulberry leaves must be the organic input to raise silkworms and silkworm manure is the pure output. Therefore, I chose to invest in growing mulberry to raise silkworms to take care of organic agricultural products for the farm,” Ms. Hoa shared.

Organic strawberry products are sold by Ms. Bui Thi Khanh Hoa at much higher prices than normally produced strawberries.

Along with silkworm manure and coconut fiber, Ms. Hoa invested in a drip irrigation system to each tree. The lines are responsible for transporting nutritional yeast made from soy protein, fish protein, chicken eggs, fermented yogurt or products soaked in garlic, lemongrass, and chili to prevent pests and diseases for plants.

The agricultural products of Ms. Hoa's farm grown in greenhouses all have high productivity, high quality and relatively stable output. Ms. Hoa said: "The company's vegetables are sold at prices about 20% higher than the market price. The product output is quite stable."

Silkworm manure is mixed with coconut fiber as a growing medium for vegetables and fruits.

Strawberries grown in ^1,000m2 greenhouses alone yield an average of about 4 tons of fruit per crop, with prices ranging from 300,000 - 600,000 VND/kg, depending on whether the fruit is small or large.

Ms. Hoa also grows melons in ^a 1,000m2 greenhouse, each crop yields about 6 tons, selling for 70,000 VND/kg. From October 2024, Ms. Hoa will export 500kg of herbs to Singapore each month, at 70,000 VND/kg for all types.

Ms. Hoa said that using silkworm manure increases productivity and product value. Vegetables and fruits grown in greenhouses help her take the initiative in fertilizing, watering, and providing nutrients for the plants.

Ms. Hoa's current way of selling is also very unique. "Currently, we sell products directly by shipping nationwide and absolutely not through any supermarkets, agents, or stores for fear of being "labeled". We produce and supply directly to consumers to reduce costs for buyers. All products have traceability stamps," Ms. Hoa said.

Using silkworm manure helps Ms. Bui Thi Khanh Hoa increase productivity and product value.

According to Ms. Hoa, the demand of consumers for clean products is increasing and the company is currently unable to supply enough. At the end of November, the company opened a clean agricultural products supermarket in District 2, Ho Chi Minh City.

Ms. Hoa's closed production method is contributing to the implementation of Dak Nong province's orientation on exploiting potential and strengths to develop clean and green agriculture, thereby developing a sustainable economy.
