Basic Slag: A Cost-Effective Liming Material for Acidic Red and Lateritic Soils| Chapter 7 | Agricultural Sciences: Techniques and Innovations Vol. 4

 

Soil acidity greatly restricts crop yields in red and lateritic soils common in tropical areas, such as India. Traditional liming materials are usually too costly or not suitable for use under such conditions. Basic slag, an industrial waste from the steel industry, is a potential solution as it is highly rich in neutralising value and releases essential nutrients such as calcium, magnesium, silicon, and phosphorus slowly. This chapter assesses the advantages of basic slag in agriculture, especially in improving soil acidity and boosting crop yields. Long-term experiments suggest that it increases the soil pH, lowers toxic aluminium contents, and increases the crop yield by supplying silicon in bioavailable form that assists in stress endurance and nutrient uptake. It also treats environmental sustainability in circular economy perspectives, and the risks associated with it include heavy metal contamination and logistics, policy, and farmer knowledge issues. In general, basic slag is discovered to be a low-cost, environmentally friendly amendment that can restore marginal soils and assist in environmental sustainability objectives.

A Comprehensive Review of the Impact of Climate Change on Food Security and Crop Productivity | Chapter 5 | Research Advances and Challenges in Agricultural Sciences Vol. 7

This comprehensive review delves into the intricate change of climate, assessing its profound impact on global food security and crop productivity. Climate change and its variability are serious concerns for humankind, as the consequences may include the rapid melting of glaciers, changes in precipitation patterns, more frequent extreme weather events, shifting seasons, the spread of pests and diseases, and other socio-economic impacts. Examining the effects of climate change on agriculture and addressing important issues, the study puts particular emphasis on the difficulties faced by sensitive areas like South Asia and sub-Saharan Africa. While navigating the challenges of mitigating crop growth pattern changes caused by climate change, the review emphasizes the urgency of adaptive measures for sustainable global agriculture. In addition, it examines how biodiversity may be affected by climate change while taking into account the interdependence of natural systems. Highlighting the imperative for innovation, the review underscores the pressing need for transformative farming methods to tackle the multifaceted challenges posed by climate change. The emphasis is on ensuring the resilience of global agriculture in the face of climatic shifts. In conclusion, the review provides a compelling call to action, advocating for the prompt implementation of innovative farming practices to fortify the global agricultural sector against the evolving challenges brought about by climate change, fostering sustainability and adaptability. Overall, the review underscores the intricate relationship between climate change, food security, and biodiversity, emphasizing the critical importance of proactive measures to mitigate the adverse effects and safeguard planetary health.

Studies on Crop Physiology and Productivity | Chapter 7 | Cutting-edge Research in Agricultural Sciences Vol. 13

 Understanding crop physiology offers us with intriguing information and expertise that we can use to improve crop management and productivity. Crop physiology is the study of how plants work in both normal and stressful situations. Many physiological characteristics of cereal crops (wheat, rice, sorghum, and barley) have been examined in Iraq over the previous two decades, with promising results. These included physiological aspects of wheat tillering and their relationship to crop management and grain yield, seed priming of rice and sorghum for better seed germination and field establishment, accurate timing of agrochemicals application (e.g. nitrogen fertiliser and plant growth regulators) based on certain critical growth stages to increase grain yield of wheat and barley, and seed priming of rice and sorghum for better seed germination and field establishment (WUE). The goal of these four case studies was to use physiological approaches to improve cereal management and, as a result, increase grain output. The use of a mix of crop physiology and crop management has resulted in significant gains in grain output in several cereal crops. For each case study, full details of the techniques and accomplishments will be shared. Finally, this strategy may be a solid and practical way to boost crop output while conserving water.
