Advantages of integrated water and fertilizer technology-1

Advantages of Integrated Fertilizer Technology:

Compared to conventional fertilization methods, integrated fertilization offers the following advantages:

Saving labor for fertilization:

In crop production, managing water and fertilizer requires significant labor. Integrated fertilization technology allows for simultaneous management of both water and fertilizer, saving significant labor for irrigation and fertilization.

Improving fertilizer utilization efficiency:

With integrated fertilization technology, dissolved fertilizer is delivered directly to the areas where crop roots are most concentrated, ensuring rapid nutrient absorption by the roots.

Micro-irrigation significantly improves fertilizer utilization efficiency because the wetted area is limited to the root-concentrated areas and the water and fertilizer solution is distributed as evenly as possible. Furthermore, the low flow rate of micro-irrigation significantly prolongs the time it takes for crops to absorb nutrients. With drip irrigation, nutrient-rich water droplets slowly seep into the soil, extending the time it takes for crops to absorb water and fertilizer. Irrigation can be stopped immediately when the soil is saturated, significantly reducing nutrient losses to deeper soil layers caused by excessive irrigation, particularly leaching of nitrate and urea.

However, in traditional farming, fertilization and irrigation are performed separately. After fertilizer is applied to the soil, if irrigation is delayed or insufficient, the fertilizer remains in the soil and is not fully absorbed by the roots. While irrigation can achieve saturation, the duration of irrigation is short, shortening the time available for root nutrient uptake. Improved fertilizer utilization efficiency means reduced fertilizer application, saving fertilizer. Fertilization quantity and timing can be controlled flexibly, conveniently, and accurately. Targeted fertilization can be implemented based on crop nutrient requirements, addressing deficiencies and achieving precise fertilization. For some crops, such as corn and potatoes, their peak fertilizer needs coincide with row closures, making traditional fertilization impractical. Drip irrigation, on the other hand, offers unlimited fertilization, allowing for fertilization at any time, truly tailored to the crop's nutritional needs. Film mulching effectively increases ground temperature, inhibits weed growth, prevents salt accumulation in the soil surface, and reduces disease. However, mulching often prevents irrigation and fertilization. Using drip irrigation under the film eliminates this problem. Fertilization is timely, and nutrient absorption is rapid. For intensively managed farms or orchards, fertilization can be completed in a shorter timeframe, resulting in uniform crop growth and facilitating the optimal scheduling of field operations. It is also beneficial for the application of trace elements. Metallic trace elements are typically expensive, but micro-irrigation systems enable precise delivery, increasing fertilizer utilization, reducing application costs, and improving soil conditions. Micro-irrigation can achieve over 90% uniformity, eliminating the soil compaction that can occur with border and shower irrigation. Micro-irrigation maintains optimal soil moisture and maintains good soil structure. Because it reduces soil evaporation and maintains soil moisture for longer periods, it fosters the growth of microorganisms and promotes nutrient conversion.
