Report on Precision Agriculture Strategies and Their Contribution to Sustainable Development Goals

A series of three studies from the University of Georgia demonstrates the application of precision management in vegetable production. These strategies directly support several United Nations Sustainable Development Goals (SDGs) by tailoring agricultural inputs and practices to enhance growth, quality, and economic outcomes while promoting environmental stewardship.

Enhancing Tomato Production and Soil Health through Biochar Application

This study assessed the impact of varying biochar rates and fertilizer sources on tomato growth, mortality, yield, and profitability. The findings provide critical insights for sustainable farming practices.

• Key Finding 1: Biochar application significantly reduced plant mortality.
• Key Finding 2: Soil fertility was enhanced through the use of biochar.
• Key Finding 3: Optimal combinations of biochar and fertilizer influenced plant growth and yield, reducing the need for synthetic inputs.

Alignment with Sustainable Development Goals

1. SDG 2 (Zero Hunger): By increasing yield and crop survival, this practice contributes directly to achieving food security and promoting sustainable agriculture.
2. SDG 12 (Responsible Consumption and Production): The research promotes the optimization of soil amendments, encouraging a reduction in reliance on synthetic fertilizers and ensuring sustainable production patterns.
3. SDG 13 (Climate Action) & SDG 15 (Life on Land): The use of biochar improves soil climate resistance, combats land degradation, and contributes to carbon sequestration, supporting climate change mitigation and protecting terrestrial ecosystems.

Optimizing Nutrient Management in Sweet Corn for Sustainable Yields

This research examined the combined effects of biochar and different fertilizer sources on sweet corn production, focusing on nitrogen uptake, biomass, yield, and quality. The results underscore the importance of integrated soil management.

• Key Finding 1: Biochar was shown to improve soil properties and nutrient retention capabilities.
• Key Finding 2: The enhanced soil conditions led to improved nitrogen availability and boosted overall crop performance.
• Key Finding 3: The study noted that year-to-year weather variability remains a significant factor in determining nutrient use efficiency and final yield.

Alignment with Sustainable Development Goals

1. SDG 2 (Zero Hunger): The findings support more consistent and stable food production by boosting crop performance and mitigating some effects of environmental variability.
2. SDG 12 (Responsible Consumption and Production): By enabling more efficient nutrient utilization, this approach helps reduce agricultural waste and minimizes the environmental impact of fertilizer runoff.
3. SDG 15 (Life on Land): The practice contributes to healthier and more resilient soil ecosystems by improving soil structure and its capacity to retain essential nutrients.

Investigating High-Density Planting for Efficient Onion Cultivation

This study investigated how planting configurations and density affect onion bulb size distribution and marketable yield. The research highlights how spatial efficiency can drive sustainable intensification.

• Key Finding 1: A twin-row, high-density planting arrangement resulted in a more efficient use of land, increasing the yield per acre.
• Key Finding 2: This configuration improved the uniformity of onion bulb size, which positively influences crop quality and marketable yield.
• Key Finding 3: The method provides growers with a strategy to target specific bulb sizes, thereby meeting diverse market demands and reducing post-harvest waste.

Alignment with Sustainable Development Goals

1. SDG 2 (Zero Hunger): The strategy directly addresses the need for sustainable agricultural intensification by increasing food production on a given area of land.
2. SDG 8 (Decent Work and Economic Growth): By improving marketable yield and crop quality, the practice has the potential to increase profitability and support sustainable economic growth for agricultural producers.
3. SDG 12 (Responsible Consumption and Production): This approach exemplifies a sustainable production pattern by maximizing land-use efficiency, a crucial element in producing more food with fewer resources.

Analysis of Sustainable Development Goals in the Article

1. Which SDGs are addressed or connected to the issues highlighted in the article?

• SDG 2: Zero Hunger

  The article directly addresses this goal by focusing on research aimed at maximizing crop yield and quality for vegetables like tomatoes, sweet corn, and onions. The studies explore methods to increase productivity and sustainability in food production, which are central to ensuring food security.

• SDG 9: Industry, Innovation, and Infrastructure

  The entire article is based on scientific research and innovation conducted at the University of Georgia. It highlights how “precision management” and “practical data driven recommendations” stemming from this research can upgrade agricultural practices, contributing to a more innovative and sustainable agricultural industry.

• SDG 12: Responsible Consumption and Production

  The research promotes sustainable production patterns by finding ways to “reduce reliance on synthetic fertilizers” and “get more out of their nutrients, reduce waste.” The focus on maximizing planting efficiency with twin-row arrangements for onions also speaks to the efficient use of natural resources (land).

• SDG 13: Climate Action

  The article mentions that the research provides insights for “improving climate resistance in Coastal Plain soils.” It also notes that “year-to-year weather variability played a key role,” and the proposed methods aim to achieve “more consistent yields,” which strengthens the adaptive capacity of agriculture to climate-related challenges.

2. What specific targets under those SDGs can be identified based on the article’s content?

• Target 2.3: Double the agricultural productivity and incomes of small-scale food producers.

  The research aims to increase “yield” and “profitability” for growers. The study on onions, for example, investigated how planting density could increase the “yield per acre of land” and “marketable yield,” directly contributing to agricultural productivity.

• Target 2.4: Ensure sustainable food production systems and implement resilient agricultural practices.

  This is a core theme of the article. The use of biochar is explored to “improve soil quality,” “enhance soil fertility,” and “enhance soil properties and nutrient retention.” These practices are designed to create more sustainable and resilient agricultural systems that can adapt to climate variability and improve land quality over time.

• Target 9.5: Enhance scientific research, upgrade the technological capabilities of industrial sectors.

  The article is a summary of “three recent studies conducted by researchers at the University of Georgia.” The work of Dr. McAvoy, which “serves the vegetable industry by disseminating relevant information,” is a clear example of enhancing scientific research and applying it to improve an industrial sector (agriculture).

• Target 12.2: Achieve the sustainable management and efficient use of natural resources.

  The study on onion planting density focuses on the “more efficient use of space” to increase yield per acre. Similarly, the research on biochar and fertilizers aims to help growers “get more out of their nutrients,” which represents a more efficient use of fertilizer resources.

• Target 13.1: Strengthen resilience and adaptive capacity to climate-related hazards.

  The article explicitly states that the research provides insights for “improving climate resistance.” The studies address the challenge of “year-to-year weather variability” by seeking methods that lead to “more consistent yields,” thereby strengthening the resilience of crop production to climate fluctuations.

3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?

• Yield and Productivity Metrics

  The article mentions several direct indicators of agricultural productivity, including “yield,” “marketable yield,” and “yield per acre.” These can be used to measure progress towards Target 2.3.

• Economic Performance Metrics

  The study on tomatoes assessed “economic returns” and “profitability,” which are direct indicators for measuring the income aspect of Target 2.3.

• Soil and Plant Health Metrics

  Indicators for sustainable practices (Target 2.4) are mentioned, such as improved “soil fertility,” “nutrient retention,” “nitrogen uptake,” and reduced “plant mortality.” These metrics quantify the health and resilience of the agricultural system.

• Resource Efficiency Metrics

  Progress towards Target 12.2 can be measured by the “efficient use of space” (planting density) and “nutrient use efficiency.” A reduction in the “reliance on synthetic fertilizers” for the same or better yield would also be a key indicator.

• Climate Resilience Metrics

  An indicator for Target 13.1 is the achievement of “more consistent yields from year to year” despite “weather variability.” This demonstrates an increased adaptive capacity to climate-related challenges.
