Background of the Study
The use of pesticides in agriculture is common in many regions of Nigeria, including Minna Local Government Area (LGA) in Niger State. Pesticides are employed to protect crops from pests and diseases, thus increasing agricultural yields. However, improper or excessive use of pesticides can lead to adverse environmental effects, particularly on soil health. Pesticides can reduce soil biodiversity, alter nutrient cycles, and contaminate water resources. These issues have raised concerns among environmentalists, agricultural experts, and local farmers about the long-term impacts of pesticide use on soil health. This study seeks to investigate the impact of improper pesticide use on soil health in Minna LGA and explore sustainable practices that could mitigate these effects (Audu & Musa, 2024).
1.2 Statement of the Problem
Improper use of pesticides in Minna LGA has led to concerns about the deterioration of soil health, which in turn affects agricultural productivity. Pesticides, when misused, can lead to soil contamination, loss of microbial life, and reduced fertility. These environmental issues have serious implications for farmers' livelihoods and the local ecosystem. This study aims to assess the impact of pesticide misuse on soil health in Minna and identify measures to promote safer and more effective pesticide management practices.
1.3 Objectives of the Study
• To assess the impact of improper pesticide use on soil health in Minna LGA.
• To identify the extent of soil contamination caused by pesticide misuse in the region.
• To recommend best practices for pesticide management to reduce negative impacts on soil health.
1.4 Research Questions
• What is the impact of improper pesticide use on soil health in Minna LGA?
• How has pesticide misuse affected soil biodiversity and fertility in the area?
• What practices can be adopted to minimize the environmental impact of pesticides on soil health?
1.5 Research Hypothesis
• H1: Improper pesticide use has significantly degraded soil health in Minna LGA.
• H2: Pesticide misuse has led to a reduction in soil fertility and microbial diversity.
• H3: Sustainable pesticide management practices will improve soil health and agricultural productivity in Minna LGA.
1.6 Significance of the Study
This study will provide valuable insights into the relationship between pesticide use and soil health, helping to inform farmers, local authorities, and environmental organizations about the risks of improper pesticide application. The findings will contribute to the promotion of sustainable agricultural practices in Minna and other similar regions in Nigeria. Additionally, the study will aid policymakers in developing regulations for safer pesticide use (Audu & Musa, 2024).
1.7 Scope and Limitations of the Study
The study will focus on the impact of improper pesticide use on soil health in Minna LGA. It will evaluate soil contamination, fertility levels, and biodiversity in agricultural areas. Limitations may include the difficulty of obtaining detailed records on pesticide usage and soil health parameters over time.
1.8 Operational Definition of Terms
• Pesticides: Chemical substances used to kill or control pests that threaten crops.
• Soil Health: The ability of soil to support plant growth, maintain biological diversity, and sustain ecological balance.
• Soil Contamination: The presence of harmful substances, such as pesticides, in the soil that negatively affect soil quality and plant health.
