is a sustainable farming system based on natural principles, aiming to maintain and improve the health of soil, crops and animals. Organic agriculture limits or completely eliminates chemical fertilizers, insecticides, herbicides and other synthetic chemicals. Instead, it uses natural methods such as organic fertilizers, intercropping, crop rotation and biological control to maintain productivity and product quality. In this article, join Ha Long Xanh to explore improving productivity with organic agriculture and contributing to the sustainable development of agriculture.
Definition of Organic Agriculture
According to the standards of the United Nations Food and Agriculture Organization (FAO), organic agriculture is a sustainable farming system based on natural principles, aiming to maintain and improve the health of soil, crops and animals. It limits or completely eliminates chemical fertilizers, insecticides, herbicides and other synthetic chemicals. Instead, it uses natural methods such as organic fertilizers, intercropping, crop rotation and biological control to maintain productivity and product quality.
Over recent decades, crop yields have increased significantly through new crop varieties, modern cultivation methods and widespread chemical fertilizer and insecticide use. However, excessive use has caused many negative effects on the environment, human health and crop health. According to a study by Vietnam's Ministry of Agriculture and Rural Development, rice yields in Vietnam increased from 2,5 tonnes/ha in 1980 to 6,3 tonnes/ha in 2022. However, chemical fertilizer use in rice cultivation increased from 150 kg/ha in 1980 to 250 kg/ha in 2022. Insecticide use in rice cultivation also increased from 0,2 kg/ha in 1980 to 0,4 kg/ha in 2022.
Organic agriculture is not simply a cultivation method, but also a philosophy and way of life. It respects biodiversity and natural balance while helping protect the environment and human health.
Current productivity in conventional agriculture
Over recent decades, crop yields have increased significantly through new crop varieties, modern cultivation methods and widespread chemical fertilizer and insecticide use. However, excessive use has caused many negative effects on the environment, human health and crop health.
According to a study by Vietnam's Ministry of Agriculture and Rural Development, rice yields in Vietnam increased from 2,5 tonnes/ha in 1980 to 6,3 tonnes/ha in 2022.

Insecticide use in rice cultivation also increased from 0,2 kg/ha in 1980 to 0,4 kg/ha in 2022.
Excessive chemical fertilizer and insecticide use not only has negative effects on the environment and human health but also reduces their effectiveness. This means farmers must spend more on fertilizers and insecticides, while profits from agricultural production decrease.
Exploring how organic agriculture improves productivity
With the current problems and challenges in conventional agriculture, organic agriculture is becoming an effective solution for improving productivity and ensuring the sector's sustainable development. In this article, we will explore its basic principles and how to apply them to improve agricultural productivity.
Basic Principles of Organic Agriculture
Organic agriculture has three basic principles: soil and water management, organic fertilizer use and pest and disease control, and maintaining biodiversity. These principles are applied to maintain and improve soil, crop and animal health, thereby increasing agricultural productivity.
Soil and water management
Soil is a valuable agricultural resource, and sustainable soil management is very important in organic agriculture. Soil improvement and protection methods such as intercropping, crop rotation, organic fertilizers and biodiversity protection all play important roles in maintaining soil health.
Water-saving irrigation and water conservation are also very important in organic agriculture. Smart irrigation techniques such as cyclical irrigation and automated systems can save water and ensure clean water supplies for crops.
Organic fertilizer use and pest and disease control
Using organic fertilizers is very important for improving crop yields in organic agriculture. Organic fertilizers are produced from natural sources such as cow manure, livestock manure, farmyard manure, vermicompost and other natural fertilizers. Their use not only supplies nutrients but also improves soil fertility, helping maintain soil health over the long term.
Pest and disease control is also very important in organic agriculture. Instead of chemical insecticides, farmers can apply biological control methods such as beneficial insects, resistant crop varieties or natural insecticides such as neem oil.
Maintaining biodiversity
Biodiversity is an important factor in organic agriculture. Maintaining it supports natural balance and minimizes risks from pests, diseases and harmful insects. It also increases the diversity of agricultural products and helps protect the environment.
Improving Soil and Water in Organic Agriculture
As discussed above, soil and water management is very important in organic agriculture. Below are some methods for improving soil and water.
Soil improvement and protection methods
In organic agriculture, methods such as intercropping, crop rotation and organic fertilizer use are very important for soil improvement and protection. They improve soil fertility, maintain moisture and supply nutrients to crops.
Natural fertilizers such as cow, livestock and farmyard manure also improve soil quality in organic agriculture. Organic fertilizer use not only improves soil fertility but also maintains long-term soil health.
Water use efficiency and water conservation
Efficient water use and water conservation are very important in organic agriculture. Smart irrigation techniques such as cyclical irrigation and automated systems can save water and ensure clean water supplies for crops.
Soil protection methods such as intercropping and crop rotation also retain soil moisture and minimize water evaporation. This maintains soil moisture and reduces water use in agricultural production.
Effects on crop yields
Improving soil and water in organic agriculture has a major effect on crop yields. Properly improved and protected soil supplies sufficient nutrients and helps plants grow healthily. Efficiently used and conserved water also ensures optimal plant development.
Using Organic Fertilizers
Organic fertilizer use is one important factor in organic agriculture. Below are some benefits of using fertilizers and organic matter in organic agricultural production.
Benefits of organic fertilizer
Organic fertilizers are natural fertilizers produced from sources such as cow manure, livestock manure, farmyard manure and other natural fertilizers. Their use supplies nutrients naturally and safely, without harming human health or the environment.
Organic fertilizer also improves soil fertility, maintains moisture and supplies nutrients to crops. This helps plants grow healthily and increases yields.
Optimal application methods and timing
Organic fertilizer must be applied correctly and at the right time for maximum effectiveness. It is usually applied to soil before sowing or planting. Apply it evenly and avoid excessive fertilizer in any particular area.
Application timing is also very important. Spring application helps crops grow vigorously during the growth stage, while autumn application helps crops accumulate nutrients for flowering and fruiting.
Effects on crop health and productivity
Organic fertilizer use has a major effect on crop health and productivity. These natural fertilizers supply nutrients naturally and safely, without harming human health or the environment.
Organic fertilizer also improves soil fertility, maintains moisture and supplies nutrients to crops. This helps plants grow healthily and increases yields.
