Excessive Use Of Inorganic Fertilizers Research Articles

Impact of Bio-Organic Fertilizer Incorporation on Soil Nutrients, Enzymatic Activity, and Microbial Community in Wheat–Maize Rotation System

Excessive use of inorganic fertilizers disrupts soil nutrient balance and leads to soil degradation and a decrease in biodiversity. In contrast, bio-fertilizers enhance soil structure and fertility and promote plant growth and sustainable agriculture development. Therefore, this study focused on a rotation system of winter wheat and summer maize and aimed to explore the effects of applying chemical fertilizer (NPK) and bio-fertilizer (BF) in the winter wheat season on the sustainable soil development of current wheat and subsequent maize. Before sowing winter wheat four fertilization treatments were, respectively CK (100% NPK at 750 kg ha−1), A (60% NPK at 450 + 20% BF at 150 kg ha−1), B (60% NPK at 450 + 40% BF at 300 kg ha−1), and C (60% NPK at 450 + 60% BF at 450 kg ha−1), conducted. The results showed that treatment A (60% NPK + 20% BF) replacing the NPK at 300 kg ha−1 with BF at 150 kg ha−1 significantly soil nutrient contents, enzyme activity, and microbial metabolic activity. The study also found a positive correlation between soil parameters (total nitrogen, alkaline nitrogen, available phosphorus, organic matter, urease, and alkaline phosphatase in the winter wheat and maize cropping season). Furthermore, the soil microbial composition showed significant enrichment of Proteobacteria, Acidobacteria, Actinobacteria, and Firmicutes, and variations among treatments. Moreover, the application of biofertilizer enhanced the diversity of soil fungi species, particularly during the winter wheat season. This study highlights the importance of integrating biofertilizers with NPK fertilizer for agricultural system conversion and promoting agricultural production and sustainability.

Fertilizer Optimization through Machine Learning-driven Models: An Empirical Investigation on Smart Farming of Amaranth

Amaranth is a highly nutritious leafy vegetable cum pseudo-cereal crop known for its adaptability to various climatic conditions, making it a promising crop for addressing the food security and nutritional needs of a growing population. To enhance its quality and boost yields, farmers mainly depend on synthetic fertilizers. However, the excessive use of inorganic fertilizers to maximize crop yields poses significant ecological risks. This study aimed to investigate the impact of excessive inorganic fertilizer on the growth, yield, and physiological attributes of Amaranthus with the aid of advanced machine learning paradigm. An experimental pot trial was conducted using different NPK fertilizer dosage regimes, and agronomic parameters such as moisture level, crop yield, plant height, leaf length, leaf width etc. were measured and analyzed using statistical methods. The results demonstrated that the application of excessive inorganic fertilizer initially promoted plant growth but surpassed optimal levels resulting in negative effects, including stunted growth and reduced vigor. By identifying the Amaranthus's productivity and adaptability in different chemically treated soil conditions and automatically phenotyping its traits using image-based machine learning models, this study aims to determine the overuse of synthetic fertilizers. A comparative evaluation of different learning algorithms was carried out and the experimental result proves that SVM classifier could be a more appropriate learning algorithm for the proposed system with 80% accuracy. These findings highlight the importance of adopting sustainable fertilizer practices for the cultivation of Amaranthus and emphasize the need for ecological balance in crop production systems.

Effect of Intercropping with Cowpea and Maize with Organic Manure Application on the Physiological Parameters

Intercropping involves cultivating two or more crops simultaneously in the same field, optimizing the use of land, water, light, and nutrients for higher yields compared to sole cropping. Organic manures, such as farmyard manure, poultry manure, oilseed cake, vermicompost, and bio-slurry, play a vital role in enhancing soil health by providing essential nutrients and supporting microbial populations. In contrast, excessive use of inorganic fertilizers can lead to environmental degradation. Present study explores the synergistic effects of intercropping and organic manure application on the physiological parameters of maize (Zea mays) and cowpea (Vigna unguiculata). Agricultural practices like intercropping optimize resource utilization and enhance overall productivity, especially in regions with limited water resources like Mizoram, India. These practices exhibit positive responds when combined with organic manure on soil health and yield attributes on crops. The experiment was laid out in randomized block design (RBD) with ten treatments replicated thrice. The result indicate that plants treated with Maize + Cowpea (2:1) + 50% of RDN (Recommended doses of Nitrogen) through Farm Yard Manure + 50% of RDN through Poultry Manure + Lime (200 kg ha-1), resulted in significantly maximum physiological parameters of the crops.
