PaThe use of Nisoluble fertilizers has emerged as a major agroinhibition to increase efficiency, restore soil health and maintain high yields in forage crops such as maize. Conventional fertilizers often cause uneven nutrient distribution, poor crop response, and environmental damage. In contrast, watersoluble fertilizers provide a balanced nutrient supply, improving soil health and preventing issues such as nitrate accumulation in forage, which can harm livestock. Fertilizer application is important in forage production, but it comes with challenges. While increasing biomass and crude protein in corn feed, nitrogenheavy fertilizers can result in nitrate accumulation, which can harm livestock. Effective fertilizer use provides balanced nutrient supply, improves crop response and reduces environmental impacts. Indiscriminate fertilizer application can lead to poor crop yields, degradation of soil health and pollution.
Field trials reveal substantial variability in nutrient supply, nutrient use efficiency, and crop responses. Such discrepancies across fields affect overall fodder productivity. To combat these inefficiencies, precise nutrient and crop management tailored to specific field characteristics is essential. Knowledgeintensive approaches to managing soil and fertilizer delivery can significantly improve results in forage production. Water soluble fertilizers provide a promising solution by offering better nutrients for plants.
These fertilizers are completely water soluble and have a low salt index, making them easy to apply as foliar sprays or through irrigation. Available in various NPK formulations (e.g., 191919), watersoluble fertilizers also contain secondary nutrients such as sulfur and zinc. They ensure that nutrients remain available to crops without being affected by environmental factors such as leaching, erosion or evaporation. Water soluble fertilizers improve nutrient use efficiency by preventing nutrient wastage.
For example, about 2530% of recommended fertilizer doses can be saved through watersoluble fertilizers, reducing input costs for farmers, while reducing input costs. These fertilizers do not contribute to salt accumulation in the soil, maintaining soil health in the long term. Water soluble fertilizers can be used in a variety of field conditions and provide an efficient, balanced nutrient supply, leading to higher forage yields and improved nutritional quality of forage. While watersoluble fertilizers provide many benefits, there is a danger of nutrient overload if they are overapplied or improperly diluted, which can result in phytotoxic injury (plant damage).
This underlines the need for careful monitoring and management to ensure correct dosing and application techniques. Field trials conducted by Krishi Vigan Kendra, Barnala assessed the effectiveness of water soluble fertilizers (NPK 191919) in maize fodder production. The study compared three fertilizer management practices: farmer practice, dosed fertilizer (RDF) and foliar application of watersoluble fertilizers.
Trials showed that foliar application of water soluble fertilizers at 1% concentration, combined with 75% RDF, significantly increased maize plant growth (fresh and dry weight) and green fodder yield. The nutritional quality of the fodder also improved compared to traditional practices. Water soluble fertilizers reduce leaching, runoff losses of key nutrients (N, P, K) and nitrogen volatilization, which translates to lower production costs and reduced environmental impact.
Lower nutrient wastage and improved efficiency result in reduced financial burden for farmers, especially in terms of fertilizer costs. Israel, known for its waterefficient agricultural practices, has pioneered the use of fertilizer, which integrates irrigation with fertilizer application. Water soluble fertilizers are dissolved in irrigation water and delivered directly to the root zone through drip irrigation systems.
Australian farmers combine the use of watersoluble fertilizers with organic and slowrelease fertilizers to achieve a balanced nutrient profile. Japan has been at the forefront of developing controlledrelease watersoluble fertilizers, which allow nutrients to be released slowly over a long period of time. In Europe, particularly in countries such as the Netherlands, sustainable agriculture certification schemes encourage the use of watersoluble fertilizers in combination with environmentally friendly farming practices.
Farmers need to be educated about the benefits of water soluble fertilizers and proper application methods. Precision farming techniques like soil testing and nutrient mapping should be integrated with the use of water soluble fertilizers. This ensures that nutrient management is tailored to specific field conditions, reducing wastage and improving crop responses. Ongoing research should focus on the creation of new watersoluble fertilizers that cater to different crops and environmental conditions.
Policies and subsidies promoting the use of environmentally friendly and efficient fertilizers, such as watersoluble fertilizers, should be strengthened. Watersoluble fertilizers should be integrated with other sustainable agricultural practices, such as crop rotation, organic matter incorporation and water management techniques. Watersoluble fertilizers represent a sustainable and efficient alternative to conventional fertilizers in maize feed production.
They improve fertilizer use efficiency, restore soil health and ensure higher fodder yield without compromising quality. Watersoluble fertilizers provide a balanced, environmentally friendly and costeffective approach that can help farmers maintain agricultural productivity while reducing environmental risks.
