1、Chemical fertilizer reduction and soil fertility maintenance in rice

At the pilot site of the rice-fish coculture system, which is one of the five “globally important agricultural heritage systems” (GIAHS), we conducted a 4-year study to compare fertilizer use, rice yield, and soil fertility in rice-fish coculture and rice monoculture.

2、Can the co

Here we test whether the co-cultivation of rice and fish into one “rice-fish system” (RFS; fish refers to aquatic animals in this article) could help sustain rice production.

3、Fertilizer Management Strategies for Sustainable Rice Production

From the various field experiments conducted in some major rice growing countries is proved that IPNS is the best management practices for increasing rice yield and sustaining soil health.

Application of Organic Fertilizer to Increase the Productivity of Tiger Shrimp Rice Cultivation in Brackish Water Affected Land With the Coculture System

Organic fertilizer applications proved beneficial for rice and shrimp, enhancing plankton growth and serving as a natural feed source for shrimp. This reciprocal relationship demonstrates the potential of organic fertilizers to boost productivity and sustainability in rice-shrimp coculture systems.

Comparison of nitrogen balances and efficiencies in rice cum prawn vs. rice cum fish cultures in Mymensingh, North

Our findings suggest that rice cum prawn cultures without chemical fertilization and without additional feed are economically possible and thus highly recommendable for small scale farmers as they reduce negative environmental impacts.

Recent Developments in Rice

Fish production from rice fields was often impacted by the efforts to raise rice production, such as increased use of pesticides, chemical fertilizer, and introduction of new and high yielding rice varieties which were often not favorable to fish growth.

Ammonia Volatilization and Nitrogen Utilization Efficiency in Response to Urea Application in Rice Fields of the Taihu Lake Region, China

Surplus N with the highest N rate resulted in lodging of rice plants, a decreased rate of nitrogen fertilizer utilization, and reduced rice yields. Calculated from this experiment, the most economical N fertilizer application rate was 227 kg ha −1 for the type of paddy soil in the Taihu Lake region.

Studies on Protein Content in Rice Grain : II. Effects of the fertilization on protein content and protein produtction in paddy grain

As to associated effects of planting density and nitrogen supply on protein content (%) and protein production (protein % × grain yield), it was observed that the more nitrogenous fertilizer applied and the more spacing was wide, the more protein % in rice grain was increased.

RICE FISH INTEGRATION UNDER ORGANIC FARMING FOR PRODUCTION OF EXPORT ORIENTED ORNAMENTAL FISH

Economics of the paddy production and fish production under organic fertilizers were evaluated and methods to increase productivity and recycling of paddy by-products in the rice–fish system were studied.

Effects of fertilization on crop production and nutrient

Based on the study results, a balanced nutrient application using NPK fertilization is a key management strategy for enhancing rice-rapeseed productivity and environmental safety. Agriculture...

Is Fish Protein Fertilizer Effective for Rice Fields?

Fish protein fertilizer is an organic fertilizer primarily derived from fish waste such as internal organs, bones, and skin. It contains multiple nutrients, including proteins, amino acids, minerals, and vitamins, which significantly promote plant growth.

First, fish protein fertilizer enhances soil fertility. Its high content of proteins and amino acids serves as a nutrient source for plants, increasing soil nutrient levels. Additionally, it improves soil structure, boosting air permeability and water retention, which benefits root system development.

Second, it improves photosynthetic efficiency in plants. Photosynthesis is fundamental to plant growth, and the proteins and amino acids in fish fertilizer act as raw materials for this process. By helping plants absorb more light energy, it increases photosynthetic efficiency—critical for rice crops, which require abundant light to produce sufficient nutrients and energy.

Third, fish protein fertilizer strengthens plants’ stress resistance. In rice farming, natural disasters like drought, flooding, and pests are common challenges. The nutrients in fish fertilizer enhance plants’ ability to withstand adverse conditions and reduce damage from these threats. It also boosts disease resistance, lowering the risk of pest-related issues.

Finally, it accelerates plant growth and development. The essential nutrients in fish fertilizer provide critical nourishment for plants. For rice, this translates to faster growth, higher yields, and improved grain quality.

several precautions apply when using fish protein fertilizer. First, overapplication may lead to excessive soil salinity, harming plant growth. Second, its effectiveness depends on soil conditions; deficiencies in phosphorus or potassium, for example, may limit its benefits. Third, local climate and farming practices must be considered to optimize results.

fish protein fertilizer is a valuable organic option for rice fields, enriching soil and improving crop quality. To maximize its benefits, careful attention must be paid to dosage, soil composition, and environmental factors.
