1、Integrating low levels of organic fertilizer improves soil fertility

Organic fertilizers are applied to soil in precise amounts to increase SOC and other vital plant nutrients, particularly N-P-K and micronutrients, in the soil (Akhtar et al., 2018; Iqbal et al., 2021).

2、The effects of organic fertilizer on loss risk of nitrogen and

Organic fertilizer (OF) application has been extensively reported to effectively improve arable soil fertility and mitigate nutrient losses.

3、Co

The combined use of organic manure and chemical fertilizer (CF) is considered to be a good method for sustaining high crop yields and improving soil quality.

4、Effect of the Different Fertilization Treatments Application on Paddy

The application amount of fertilizer is believed to dramatically influence soil bacteria in paddy fields, and soil bacteria critically affect soil enzyme activities and the growth of rice in paddy fields.

Effects of organic fertilizer replacing chemical fertilizer on organic

The aim was to decrease chemical fertilizer use and improve soil carbon sequestration. Replacing 50% chemical nitrogen fertilizer with organic fertilizer can inhibit the mineralization of organic carbon in yellow paddy soil by increasing the active organic carbon components.

Effects of long

Long-term combined application of chemical fertilizer and organic fertilizer effectively increased the contents of organic carbon, total nitrogen and total phosphorus in paddy soil, and increased microbial biomass and extracellular enzyme activity.

Balanced fertilization modulates colloidal phosphorus dynamics in paddy

This study investigates the influence of balanced fertilization on colloidal P dynamics in paddy field soils and surface water by categorizing colloidal P into nano colloidal (1–100 nm), medium colloidal (100–450 nm), and coarse colloidal (450–1000 nm) fractions.

Combining organic and inorganic fertilization increases rice yield and

We performed field experiments between 2015 and 2020 in a paddy field exposed to different organic and inorganic fertilizer treatments to test the above hypotheses.

APPLICATION OF NPK 15

NPK compound fertilizer in the future is an NPK compound fertilizer that can be applied to all conditions of the nutrient status of paddy soils, especially P and K nutrients.

Nitrogen and phosphorus losses from paddy fields and the yield of rice

The assessment and control of losses of nitrogen (N) and phosphorus (P) from paddy fields is critical to improve the quality of water and atmosphere on earth.

Compound fertilizer can be used in paddy fields, but the following considerations must be addressed:

1. Water Availability: Compound fertilizer contains essential nutrients like nitrogen, phosphorus, and potassium, which are critical for rice growth. without adequate water, these nutrients cannot be effectively absorbed by the plants. Ensure sufficient irrigation before applying compound fertilizer to optimize nutrient uptake.

2. Timing: Apply compound fertilizer during the early growth stages of rice to provide continuous nutrition throughout development. Delaying application until later stages reduces effectiveness, as the plants may have already depleted soil nutrients.

3. Application Method: Spread the fertilizer evenly across the paddy field and incorporate it into the soil using tools or machinery. Proper mixing with soil enhances nutrient absorption by rice roots.

4. Dosage: Adjust the amount of compound fertilizer (typically per mu*) based on soil fertility and rice growth conditions. Excessive use can lead to overgrowth and reduced yields, while insufficient doses may cause nutrient deficiencies.

5. Frequency: Apply compound fertilizer twice—once during early growth and again in mid-development—to maintain steady nutrient supply. Relying solely on late-stage application risks inadequate nutrition.

6. Environmental Conditions: Avoid applying compound fertilizer under extreme conditions. High temperatures and humidity accelerate nutrient loss, while low temperatures or drought inhibit absorption. Ideal conditions ensure maximum efficacy.

While compound fertilizer can be used in water-deficient paddy fields, success depends on ensuring adequate water, proper timing, application methods, dosage, frequency, and environmental suitability. Adhering to these guidelines promotes efficient nutrient use and supports healthy rice growth.
