In the process of ecological agriculture, why do people need to apply organic fertilizer to the soil regularly? Hello, with the development of science and technology, the utilization rate of chemical fertilizer now accounts for 80%, while the utilization rate of organic fertilizer is getting smaller and smaller.

The first point: chemical fertilizer is inorganic. Long-term use will make the land sour, soil harden, and the ability of maintaining fertilizer and water will decrease. .

The second point: most chemical fertilizers have the characteristics of high content and fast fertilizer efficiency, but most of them are difficult to last. .

The third point: the composition of chemical fertilizer is relatively single, which can not meet the needs of plant growth in various periods.

Organic fertilizer is a complete fertilizer, organic and contains 16 nutrients needed by plants. It can improve the soil, improve the utilization rate of fertilizer, improve the ability of soil to preserve fertilizer and water, increase the organic matter in the soil, and make the soil fertile and loose. The content of organic fertilizer is low and the fertilizer efficiency is slow, but it lasts for a long time, usually two to three years.

This is why it is necessary to apply organic fertilizer to the soil regularly. .

The difference between organic agriculture and ecological agriculture The so-called organic agriculture refers to a production system that does not use synthetic fertilizers, pesticides, growth regulators and feed additives. It relies as much as possible on crop rotation, crop straw, livestock manure, green manure, exotic organic waste, mechanical intertillage, minerals containing inorganic nutrients and biological control to maintain soil fertility and easy cultivation, supply crop nutrients and prevent pests and weeds.

Ecological agriculture is a kind of high-efficiency and high-quality agriculture, which makes full use of the principle of material circulation and reasonably arranges the recovery and reuse of materials in the system to replace or reduce the consumption of petroleum energy and produce more products with as little input as possible. This kind of energy saves raw materials and fuel from an economic point of view and reduces pollution from an environmental point of view.

If you know about organic agriculture and eco-agriculture, you can pay attention to China Organic Agriculture Network. The information about organic agriculture is very comprehensive.

The difference between ecological agriculture, organic agriculture and prescription agriculture Ecological agriculture refers to an agricultural development model that follows the laws of ecology and ecological economics, uses systematic engineering methods and modern science and technology, and carries out intensive management on the premise of protecting and improving the agricultural ecological environment. Based on the principles of ecology and economics, modern agriculture is established by using modern scientific and technological achievements and modern management science, combined with the effective experience of traditional agriculture, and can obtain higher economic, ecological and social benefits. Ecological agriculture is a concept put forward relative to petroleum agriculture, and it is a principled model rather than a strict standard.

Organic agriculture is an agricultural production mode that follows certain organic agricultural production standards, does not use organisms and their products obtained through genetic engineering, does not use chemically synthesized pesticides, fertilizers, growth regulators, feed additives and other substances, follows natural laws and ecological principles, coordinates the balance between planting and aquaculture, adopts a series of sustainable agricultural technologies, and maintains a sustainable and stable agricultural production system.

Prescription agriculture means that farmers must invite technicians to the site for investigation before purchasing chemical fertilizers and pesticides, and prescribe the application of chemical fertilizers and pesticides according to the growth of crops and the degree of pests and diseases, combined with the scale of land use. Farmers buy a certain amount of chemical fertilizers and pesticides according to prescriptions. Prescription agriculture has put an end to the abuse of chemical fertilizers and pesticides, and can ensure that food meets hygiene standards. Therefore, many agricultural products produced by prescription agriculture, such as lettuce, apples, grapes, pears and so on. Wash with a little water and eat raw.

The difference between ecological agriculture and artificial ecological agriculture As an artificial ecosystem, ecological agriculture system has its own characteristics. On the other hand, the eco-agricultural system is an integral part of the biosphere and has all the characteristics of the biosphere, which are the most basic conditions for the existence and sustainable development of the eco-agricultural system. On the other hand, as an artificial ecosystem, the ecological agriculture system is much smaller than the biosphere and forms a more unique part, so it has its own characteristics. These characteristics are local conditions, comprehensiveness, stability, sociality and selectivity.

Ecological agriculture is an efficient artificial ecosystem, and it is an efficient agriculture with coordinated structure and function. Different from natural ecosystem, it increases human labor and intervention, so it is not only a simple natural reproduction process, but also an economic reproduction process. They are intertwined, and through human labor and intervention, their structure and functions are constantly adjusted and optimized, so that they can get more output with less input and achieve better economic, social and ecological benefits.

What's the difference between ecological agriculture and organic agriculture? Ecology and organic are two different concepts. The concept of organic (a mode of production) focuses on pure nature without adding synthetic pesticides and fertilizers. The concept of ecology (a production system) focuses on the process of imitating natural ecology, which can be recycled and often combined with planting and breeding. For example, planting crops, the by-products of crops are used as feed for aquaculture, and the by-products of aquaculture are used as fertilizer for planting. The products of eco-agriculture may or may not be organic.

ECO-agriculture, referred to as ECO for short, is a modern and efficient agriculture based on the principles of ecology and economics, which can obtain high economic, ecological and social benefits by using the achievements of modern science and technology and the effective experience of modern management science and traditional agriculture.

Through the appropriate application of chemical fertilizers and low-toxic and high-efficiency pesticides, the limitations of traditional agriculture have been broken through, but the fine traditions of intensive cultivation, application of organic fertilizers and intercropping and interplanting have been maintained.

Organic agriculture refers to the planting industry that completely or basically does not need synthetic fertilizers, pesticides, growth regulators and feed additives for livestock and poultry, but uses organic fertilizers to meet the nutritional needs of crops or organic feed to meet the nutritional needs of livestock and poultry.

Ecological Agriculture: What are the advantages of ecological agriculture? Eco-agriculture refers to the agricultural development mode of intensive management under the premise of protecting and improving the agricultural ecological environment, following the laws of ecology and eco-economics, using systematic engineering methods and modern science and technology. Eco-agriculture is a complex system of agricultural eco-economy, which combines agricultural ecosystem with agricultural economic system to maximize the overall benefits of eco-economy. It is also a large-scale agriculture integrating agriculture, forestry, animal husbandry and by-fishing, and a modern agriculture integrating agricultural production, processing and sales to adapt to the development of market economy.

Comprehensive. Eco-agriculture emphasizes giving full play to the overall function of agricultural ecosystem, taking macro-agriculture as the starting point, and comprehensively planning, adjusting and optimizing the agricultural structure according to the principle of "entirety, coordination, circulation and regeneration", so that agriculture, forestry, animal husbandry, sideline, fishery and rural primary and secondary industries can develop in an all-round way, and all industries can support and supplement each other and improve the comprehensive production capacity.

Diversity. In view of China's vast territory, great differences in natural conditions, resource base and economic and social development level, ecological agriculture fully absorbs the essence of Chinese traditional agriculture, combines modern science and technology, and equips agricultural production with various ecological models, ecological projects and colorful technical types, so that all regions can make full use of their strengths and avoid their weaknesses, give play to their regional advantages, and all industries can develop in harmony with local reality according to social needs.

Efficiency. Through material circulation, multi-level comprehensive utilization of energy and series of deep processing, ecological agriculture can realize economic appreciation, realize resource utilization of waste, reduce agricultural cost, improve efficiency, create agricultural employment opportunities for a large number of rural surplus labor force and protect farmers' agricultural enthusiasm.

Sustainability. Developing ecological agriculture can protect and improve the ecological environment, prevent pollution, maintain ecological balance, improve the safety of agricultural products, change the conventional development of agriculture and rural economy into sustainable development, closely combine environmental construction with economic development, meet people's growing demand for agricultural products to the greatest extent, improve the stability and sustainability of the ecosystem, and enhance the stamina of agricultural development.
