Organic farming: Early loss, lasting benefit


(VAN) Organic farming can reduce crop yields for the first 1-2 years, but in the long run it will bring countless benefits.

From a good point of view

The reality of chemically abusive agriculture calls for the development of a new safe, profitable and environmentally friendly agriculture in which the improvement of agricultural production, the use of organic fertilizers and the reduction of chemical fertilizers are considered. as the most effective solutions.

According to the Department of Plant Protection, there are a large amount of by-products in agriculture that can be used to make organic fertilizers at a relatively low cost, such as rice straw in rice production and waste livestock and aquaculture.

However, due to a lack of information and difficulties in the collection and processing process, farmers have yet to fully exploit the potential of these by-products.

Following the direction of the Ministry of Agriculture and Rural Development (MARD), the Department of Plant Protection (DPP) has been coordinating with localities to provide training and advice so that farmers can soon use fertilizers in a sustainable way. appropriate with great efficiency. MARD strongly suggests an increase in the use of organic fertilizers and organic matter sources to partially replace inorganic fertilizers.

Among the localities that are actively reorienting agriculture, Bac Giang is becoming a pioneer in the development of organic, safe and high-quality agro-production. With the support of the DPP and related units, Bac Giang’s agricultural industry has gradually flourished. Many agricultural products have created their own brand identity and firmly established themselves in domestic and foreign markets.

Bac Giang – an excellent example

Bac Giang farmers currently use two groups of organic fertilizers, namely traditional organic fertilizers (animals, plants and other organic wastes) and industrial organic fertilizers. Local households quickly find that organic fertilizers not only help provide nutrients to plants, but also help improve the humus content and microflora of the soil, as well as reduce leaching and evaporation. Fertilizer utilization efficiency has been greatly improved.

The organic grapefruit model of Trung Sau Sweet Grapefruit Cooperative (Cau Thay village, An Thuong commune, Yen The district) is an excellent example of using organic fertilizers in intensive citrus cultivation bringing high yield and high quality products.

“Using organic fertilizers helps the plants to grow and develop very well with few harmful pests. We almost have to worry only about the disease prevention stage. The quality of the pomelos has improved considerably, so the selling price is reasonably higher. My family sells 10,000 pomelos at the market every year with an average price of 50,000 VND/fruit (weighing 1-1.5 kg), bringing in 500 million VND (excluding costs) said Mr. Pham Nhu Trung, director of the cooperative.

Organic farming helped his family keep the farm environment cool, so Mr. Pham Nhu Trung took the opportunity to raise bees for honey, both to increase the pollination efficiency of the tree and to open up to another source of income.

In the same way, Ms. Hoang Thi Thang’s family from Ven Village, Xuan Luong Commune, Yen The District, a member of Than Truong Cooperative, also takes the initiative to use organic fertilizer on the tea plants, with very positive results.

“Tea is becoming a crop that can bring great benefits to my family as well as households in the village. Market requirements for product quality are becoming more and more stringent. If the production is not guaranteed, Yen Tea products will hardly have a place in the market.

For organic farming, the essential factor is to be very persistent because it takes time to improve the soil and add organic nutrients to the soil.

During the first two years, the tea yield can decrease by 20-30%. However, from the following years, when the soil is supplemented with enough nutrients, it will become porous, rich in humus and abundant in microflora. The roots of the plant will grow healthy and absorb nutrients at a higher rate. Performance will be restored. In fact, in good agricultural areas, yield can increase by about 10%. The tea leaves will be thicker, the tea buds plump and fresh for a long time. The tree’s operating period will also be extended.
