we need fertilizers?
Plants need 16 essential mineral nutrients. While carbon and oxygen is receive from the air and hydrogen from the water, the remaining 13 nutrients come from the soil. The lack of any such nutrient substance can affect the health and development of the plant, but also the production. Fertilizers contain all the essential nutrients for plants.
By 2050, the world's population will grow to 9 billion people. Therefore, agricultural productivity must be increased to provide it with the necessary food.
Sustainable agriculture is associated with the use of fertilizers. The main mean for achieving safe, constant and high quality agricultural production remains the proper application of fertilizers. The adoption of modern technologies, more intensive, but environmentally friendly, can significantly increase the profit of farmers.
4C - CORRECT APPLICATION OF FERTILIZERS
The 4C concept is based on the 4R principle (formulated by the Institute for Plant Nutrition, the Fertilizer Institute, the International Fertilizer Industry Association) and frames a sustainable agriculture and associates it with fertilizer application.
Fertilization is really effective if it updates the nutritional requirements of the plants with the properties of the soil, but at the same time, it has an integrated character in the applied agricultural technologies to lead to obtaining high quality vegetal productions, but at the same time, with the preservation of surrounding environment.
The 4 rules concern: the Type of fertilizer, the Dose of fertilizer applied, the Time of application of fertilizers and How to apply them. The 4C concept is an innovative approach designed to increase the efficiency of fertilizers application. 4C - The basic rules for fertilizers application are generally valid, but they will be applied depending on the specific conditions of: soil, climate, crop system, applied technology.
Scientific - 4C means 4 Rules for the correct application of fertilizers taking into account:
Type of fertilizers
It provides a balanced nutrition, taking into account the level of soil supply and the chemical composition of the fertilizer, in the form accessible to plants.
Select the most balanced fertilizer, even from the point of view of the commercial product, the economic efficiency of the product.
It is established according to the level of soil supply and the specific consumption of plants.
Use soil analysis, specific plant consumption, including plant analysis.
Time of application
It is established according to the level of soil supply, the absorption of nutrients, the vegetation phases, the risk of nutrient losses and the applied technology.
Use specialist recommendations, even nutrient control by analysing urease or nitrification inhibitors, use fractional application to improve absorption.
Method of application
It is established according to the dynamics of the root system of the plant and the absorption of nutrients, to meet the specific needs of the plants and to reduce the risk of loss of nutrients.
Use a loss-reducing application mode, incorporate fertilizers, apply taking into account the preservation.
Stages for implementing the 4C principles
Identification of the economic, social and ecological objectives of the farm included in the agricultural production system.
Selection of best practices for the management of specific fertilizers for: soil, climate, crop system.
Integration of best fertilizer management practices for all objectives and adaptation to specific requirements.
Knowledge of the principles of fertilizer application according to concept 4C.
Provides a scientific basis for correctly assessing nutrient requirements;
Answers farmer's question: Was the optimal type of fertilizer used for the respective crop, at the optimum dose, at the right time and the right place?
Contributes to the practice of sustainable agriculture with the approach of economic, social and ecological objectives.
Implementation of 4C principles
One of the challenges facing the agricultural sector is to meet the growing food demands of the world's population and, at the same time, to ensure the increased economic efficiency of agricultural farms while preserving the environment.
To speak about a sustainable agriculture means to define economic, social and ecological objectives for the agricultural farms.
The management of fertilizers application - a significant part of agricultural production - must be defined in terms of sustainability by developing a code of good practice. This involves 4 aspects of the application of the compulsory fertilizers to provide the plants with the nutrients necessary to manifest the productive potential.
4C - the 4 rules of CORRECT application of fertilizers - is an innovative approach meant to increase the efficiency of the application.
• Increasing the net income of the farm
• Contribution to regional economic development
• Increasing the quality of life, education, nutrition
• Increasing the productivity of the farm activity and using the latest technologies, while reducing the costs / unit of surface or product
• Increased access to various sources of information on agricultural management
• Maintaining or reducing the level of nutrient losses in the environment
• Reduction of soil erosion
• Reduction of NH3 emissions
• Reduction of nitrification / de-nitrification and losses of N2O or N2
• Reduction of energy consumption per unit area or farm
