In the context of high prices of agricultural materials, to reduce production costs and protect the environment, localities have encouraged and guided people to promote the application of science and technology, proactively produce and use organic fertilizers (PHC) instead of chemical fertilizers.
People of Thanh Minh commune (Thach Thanh) compost organic fertilizer.
Every year, the province has more than 1.1 million tons of livestock and poultry manure at livestock farms and other by-products such as straw, stubble, grass, vegetable leaves, sawdust, ash, rice husks... This is a large source of PHC raw materials for cultivation. If utilized effectively, it will help provide a high amount of nutrients for crops, minimize the use of chemical fertilizers, reduce costs, improve product quality, improve soil, contribute to the development of sustainable agricultural production, protect the environment...
In the production field of Thanh Minh commune (Thach Thanh), Truong Thi Hien Hien and other farmers are collecting newly cut grass to put into tanks to compost green manure. Taking us to visit the melon field that has just been composted by the people, Hien Hien said: Organic farming has many difficulties from costs, strict production techniques... so I am always concerned about researching production methods to save costs and protect the environment. Therefore, I and the people collect grass, golden apple snails, soak them in clean water, salt, and enzymes made from sugarcane molasses to make PHC. This mixture is composted for about 1 month and will be used to fertilize the cucumber and melon areas. Thanks to this PHC source, it not only provides plants with the necessary nutrients but also restores fertility to the soil, helping the soil to always be loose, prolonging the harvest time of crops and especially reducing about 50% of production costs compared to using chemical fertilizers on the market, meeting the conditions of organic agricultural production. Therefore, Hien Hien's products grown and cared for using organic methods always ensure quality and safety for users, and have been surveyed, evaluated and confirmed by many professional agencies according to standard processes.
Currently, in addition to large-scale agricultural production models, localities such as Trieu Son, Thieu Hoa, Dong Son... have instructed people to classify waste and treat organic waste as fertilizer in households, gradually changing people's habits in preserving the environment as well as saving costs for small-scale production activities. Accordingly, after classifying waste, people will use leaves, fruits, spoiled green vegetables... to compost with microorganisms, after 40 to 45 days there will be a quantity of fertilizer for plants. In addition, many farms in the province have proactively raised earthworms to get fertilizer for plants, because earthworm manure has high nutritional content; especially suitable for growing seedlings and growing organic vegetables, tubers and fruits. Mr. Nguyen Van Que, Thieu Cong commune (Thieu Hoa), said: "My family has been proactive in producing PHC for fruit trees for many years. I use earthworm manure as basal fertilizer and top dressing for trees before flowering and after each harvest or at the beginning and end of the rainy season. Compared to areas that do not use earthworm manure, I find that the plants have fewer pests and diseases, the soil is always loose, and nutrient absorption is increased... so that the trees achieve productivity and quality."
Currently, many farmers in the province have proactively composted PHC and microorganisms from agricultural waste and by-products to take care of crops. This method has shown double effectiveness when reducing production costs from 30% to 50% compared to the cost of buying chemical fertilizers, contributing to improving the soil environment, extending the harvest time, improving the quality of agricultural products... With proven advantages, using PHC is one of the solutions contributing to creating safe agricultural products, meeting the demand for safe food of consumers. However, in order to widely use PHC, localities need to promote propaganda about the effects of PHC so that people trust and apply it; encourage people to make the most of available raw materials at home, apply traditional composting methods combined with the use of biological products to improve the efficiency of processing agricultural by-products and organic waste in daily life to make PHC. In addition, organize training courses and transfer PHC composting techniques. At the same time, build an agricultural production model using appropriate and effective PHC for people to learn and replicate locally...
