Optimizing crop yields while minimizing environmental impact

Deep placement of nitrogen fertilizer (DPNF) is an agronomic measure that shows promise in addressing these issues. This review aims to offer a comprehensive understanding of DPNF, beginning with a succinct overview of its development and methodologies for implementation.

Understanding and Applying Chelated Fertilizers Effectively Based on

To grow a good crop, crop nutrient requirements (CNRs), including micronutrients, must be satisfied first from the soil. If the soil cannot meet the CNR, chelated sources need to be used. This approach benefits the plant without increasing the risk of eutrophication.

Recent and historical developments in chelated fertilizers as plant

In recent decades, many chelating compounds have been established and incorporated into agricultural systems. The most recent formulation involves the use of amino acids synthesized with one or more nutrient ions to improve fertilizer efficiency and better respond to environmental conservation.

Optimal cooperative application solutions of irrigation and nitrogen

Optimizing irrigation and nitrogen (N) fertilization cooperative application to coordinate the balance between agricultural production and ecological environment is a vital challenge for sustainable agricultural production.

Combination of nitrogen and organic fertilizers reduce N

Here, we investigated the optimal management of N fertilization by examining the combined effects of organic and N fertilizers on wheat yields, quality, and N 2 O emissions.

Chelated high-nitrogen fertilizers are compound formulations rich in nitrogen, commonly used to promote plant growth and enhance crop yields. To maximize their effectiveness, it is crucial to pair them rationally with other inputs based on soil conditions, crop requirements, and climate. Below are key recommendations:

1. Combine with Phosphate and Potassium Fertilizers

   • Phosphate fertilizers supply essential phosphorus, which strengthens root development and improves pest/disease resistance. Potassium fertilizers enhance stress tolerance, fruit quality, and taste. Balancing chelated high-nitrogen fertilizers with phosphate and potassium ensures nutrient equilibrium, boosting overall plant health and productivity.

2. Select Crop-Specific Formulations Different crops have varying nitrogen needs. For leafy vegetables (e.g., spinach, lettuce) with high nitrogen demands, choose formulations with elevated nitrogen. For fruit trees (e.g., apple, pear), moderate nitrogen application prevents compromised fruit quality. Tailoring fertilizers to crop types and growth stages optimizes results.

3. Integrate Organic Amendments Organic fertilizers (e.g., chicken manure, cow manure) provide diverse nutrients, improving soil fertility and structure. Their organic matter enhances water retention and fertilizer absorption, complementing chelated high-nitrogen products for sustained efficacy.

4. Pair with Microbial Inoculants Microbial agents (e.g., plant growth-promoting bacteria, phosphate-solubilizing bacteria) enrich soil biodiversity and nutrient availability. Combining these with chelated nitrogen fertilizers amplifies soil health and crop performance.

5. Optimize Timing and Application Methods Apply chelated high-nitrogen fertilizers during peak growth periods (e.g., spring/summer) to meet plant demands. Avoid high-temperature periods to prevent nutrient loss. Use deep or hole applications to improve efficiency and reduce runoff.

6. Coordinate with Agronomic Practices Synergize fertilization with practices like crop rotation (to suppress pests/diseases), scientific irrigation (for optimal moisture), and proper pruning (to enhance photosynthesis). Holistic management amplifies yield gains.

Effective use of chelated high-nitrogen fertilizers hinges on soil, crop, and climate-tailored strategies. Pairing them with complementary inputs and agronomic practices ensures sustainable productivity and resource efficiency.
