Use of organic fertilizers for plants’ high yield

Many farmers are starting to use organic combined with chemical fertilizers.

The plantation of more than 800 trau peppers owned by Mr. Le Xuan Dang residing at Hung Thanh hamlet, Hung Loc commune is green and fruit-bearing, which results from the combined use of organic and inorganic fertilizers. The organic fertilizers that he uses are made from a kind of waste produced by earth worms. This substance is of high nutrition and competitive price of around VND 1,500 per kg. Currently, instead of using the entire organic fertilizer, he has to use up to 2.5 kgs of inorganic fertilizer and this may cost him around VND 30,000 due to the soaring price of chemical fertilizers. The estimated investment for 800 peppers is around VND 24 million. However, when he uses 5 kgs of organic fertilizers made from earthworm waste, he needs only 1 kg of inorganic fertilizer, which costs an estimated amount of about VND 20,000 in total. Therefore, he can finally save VND 8 million out of the investment expense to grow 800 peppers.

The utilization of organic fertilizers to grow plants helps to bring about cost efficiency, economic value improvement and, above all, provide necessary nutrients to make soil more fertile. Especially, this can also prevent pests and diseases to keep tree leaves green for the whole year. Besides, peppercorn quality is also enhanced. In 2010, he gained only 2.5 million tons but, this year, he harvests 3 tons of dry pepper. At present, peppers are in blossom and Mr. Dang is expecting to see higher pepper yield, in comparison with the previous crop.

Similarly, Mr. Nguyen Duc Khai, residing at Hung Thanh hamlet, Hung Loc commune, starts using the combined organic and chemical fertilizers for his 5-year durian orchard and, at first sight, it has apparently shown its productivity. Mr. Khai shared: “Previously, I used to use chemical fertilizers and found that it took a shorter time for the trees to turn green, yet now it turns out that using organic fertilizers helps the greenness of the trees last longer. Particularly, fertilizer of this kind is able to make soil soft and fertile, which can enhance the capability of water drainage. This contributes to increasing the yield and creating sustainable agriculture.”

Currently, some farmers in the province have learned the way to make the most of agricultural wastes for organic fertilizer production. However, most agricultural wastes like straw, corn stem, corncob and corn peel, peanut stem and coffee bean peel, etc, are burned by farmers. According to scientists, the usage of wastes to manufacture fertilizers can help them to decrease expenses. Explicitly, adding organic fertilizers to plants is a very useful solution to farmers, especially when the current price of chemical fertilizer is rising. This is also to help farmers to be independent of chemical fertilizers. With the total areas of 63 thousand hectares of annual trees, more than 124 thousand hectares of perennial industrial trees as well as nearly 48 thousand hectares of fruit trees, total amount of investment in buying fertilizer amounts to thousands of VND billions. Therefore, when farmers make the best use of agricultural wastes to produce organic fertilizers, this can save a lot of costs of fertilizers, which contributes to reaching the objectives of yield improvement and sustainable agricultural production.
