1. The integration of organic and inorganic fertilization in soil testing and precision farming must start with the use of organic fertilizers. Applying organic materials enhances the organic matter content in the soil, improves its water-holding capacity and fertility, boosts microbial activity, and increases the efficiency of chemical fertilizers. It is essential to apply various types of organic fertilizers regularly to maintain soil health and support long-term agricultural sustainability.
2. Balancing nitrogen, phosphorus, and potassium is a crucial aspect of soil testing and formula fertilization. As crop yields increase, so does the demand for nutrients, leading to higher depletion of soil nutrients. Therefore, it's important to ensure proper ratios of these primary nutrients and to replenish essential micronutrients to sustain high and stable yields over time.
3. Combining land use with land replenishment, and maintaining a balance between input and output, helps create a sustainable cycle of matter and energy among crops, soil, and fertilizers. We should emphasize both the use and maintenance of soil resources, ensuring that inputs match outputs. Soil testing and formula fertilization should follow the principle of nutrient return, continuously restoring soil fertility to achieve consistent high yields and promote sustainable agricultural practices.
