Summary
This summary is machine-generated.Replacing 25% of chemical fertilizers with organic fertilizer (OF) or slow-release fertilizer (SRF) boosts mango yields and improves fruit quality. These sustainable alternatives enhance soil health and microbial activity for better crop systems.
Area Of Science
- Agricultural Science
- Soil Science
- Horticulture
Background
- Excessive chemical fertilizer use in mango orchards is unsustainable and ecologically damaging.
- Organic fertilizer (OF) and slow-release fertilizer (SRF) offer promising alternatives for sustainable mango farming.
- Detailed fertilization protocols are needed to optimize the use of OF and SRF in mango production.
Purpose Of The Study
- To evaluate the impact of substituting chemical fertilizers with OF and SRF on mango yield and fruit quality.
- To assess the effects of OF and SRF on soil nutrient status and microbial community composition.
- To propose an optimal fertilization strategy for sustainable mango cultivation.
Main Methods
- A two-year field study involving seven different fertilization strategies.
- Quantified mango yield, fruit nutritional quality (Vitamin C, sugar-to-acid ratio, solid-to-acid ratio).
- Analyzed leaf and soil nutrient concentrations and characterized soil bacterial communities (Actinobacteria, Proteobacteria).
Main Results
- Substituting 25% of chemical fertilizers with OF or SRF increased mango yields by 12.5% and 11.3%, respectively.
- Fruit quality significantly improved, with Vitamin C increasing by up to 56.9% and sugar-to-acid ratios by up to 30.3%.
- OF and SRF enhanced leaf nitrogen and phosphorus, reduced soil phosphorus and potassium, and promoted beneficial soil microbes, improving soil bacterial synergy.
Conclusions
- Organic fertilizer (OF) and slow-release fertilizer (SRF) effectively improve mango yield and fruit quality while enhancing soil health.
- A 25% substitution of chemical fertilizers with OF or SRF supports ecological sustainability and promotes a resilient soil-crop system.
- Implementing OF or SRF optimizes soil nutrient balance and fosters beneficial microbial ecosystems for sustainable agriculture.

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
The collective bacteria residing in and around plant roots are termed the rhizosphere. These soil-dwelling bacterial species are incredibly diverse....
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:
Inorganic mineral matter, which constitutes about 40 to 45 percent of the soil volume.
Organic matter, also known as humus, which makes up about 5 percent of the soil volume.
Water and air, covering about 50...
