“…Although there is growing evidence of K deficiency in rice fields in SSA ( Johnson et al, 2021 ), the K application rate was not correlated with yield and yield gap in any growing environments. Previous studies also demonstrated that yield response to K fertilizer was lower than those of N and P both in rice and maize fields ( Zingore et al, 2022 ). In the Senegal River Valley (Senegal) and Office du Niger (Mali), it is known that considerable amounts of K were provided through irrigation water and dust deposition ( Chivenge et al, 2022 ; Haefele, 2001 ).…”

“…Effective potassium management practices include soil testing, potassium fertilizer application, and applying potassium fertilizer at planting and during the vegetative stage. Research has shown that these practices can improve maize yield and potassium use efficiency [4,20,21]. Understanding the nutrient requirements of maize, as well as the nutrient content of the soil, is essential to develop a nutrient management plan that balances these needs with available resources.…”

This chapter presents a comprehensive overview of nutrient management practices tailored for optimizing maize production. It covers critical aspects, including soil testing protocols, advanced fertilizer application methods, organic and inorganic amendments, precision nutrient management approaches, integrated strategies, and conservation agriculture-based practices. Recognizing maize’s significance for global food security and economic prosperity, the chapter emphasizes efficient and sustainable nutrient management to achieve high yields. Precision technologies enable targeted fertilizer applications, while organic and inorganic amendments enhance soil fertility and nutrient cycling. Integrated nutrient management reduces environmental risks and improves long-term soil fertility. Conservation agriculture-based practices, such as reduced tillage and cover cropping, positively influence maize yield and sustainability by enhancing nutrient retention and water management. Overall, adopting appropriate nutrient management practices is crucial for maximizing maize production while ensuring food security and environmental well-being.

“…Despite the advantages of fertilizer application, increased emphasis is now being placed on the problem of plant damage, which takes a toll on both the health and quality of agricultural soils and crops [2][3][4]. With an understanding that most agronomic crops are the main global food sources for human consumption, a considerable gap still exists where access to fertilizers and their efficient use are among the major significant challenges towards ending poverty, hunger and improving human consumption, a considerable gap still exists where access to fertilizers and their efficient use are among the major significant challenges towards ending poverty, hunger and improving human health [5,6]. These fertilizers are one of the greatest consumptive materials that, when applied to the soil, can affect the seeds or seedlings through soil-fertilizer, seed-fertilizer, or soil-fertilizer-seed placement systems (Figures 1 and 2) [7].…”

“…From the fertilizer scientist's perspective, improper fertilizer recommendation, placement, and management in crop production may become the primary factors limiting global plant stand and its establishment, with the most substantial consequences in crop yields. Therefore, efforts to improve crop stand and lessen the severity and incidence of salt injury, pH changes in the seed germination zone, and ammoniacal-N toxicity needs balanced starter fertilization, which becomes the fulcrum for sustainable global food crop production [5,6,11,19,38,39]. Knowledge of the importance of starter fertilizers and their implications as influenced by frequent environmental conditions and management practices remains essential for sustainable and socio-economics of human livelihoods for successful global food production and productivity under climate change.…”

The rising shortage of fertilizer resources in crop-producing regions worldwide and the need for fertilizer use optimization to minimize the impact of salt injuries and ammonia toxicity are at the centre of a brewing storm call for sustainable fertilizer savings. The allocation of fertilizers will be an ever-increasing pressure source because of vast agricultural demands under changing climatic conditions. Therefore, starter fertilizers must complement their efficiency and aim to boost productivity and improve food quality to reduce its toxicities, and these observations are corroborated by an analysis of past and ongoing short-, medium-, and long-term experiments. Concurrently, to counterbalance nutrient uptake, fertilizing products containing select nutrients are commonly placed through soil–seed or soil–fertilizer–seed systems to enhance crop production and productivity. Knowledge of the importance of starter fertilizers and their implications as influenced by frequent environmental conditions and management practices remains essential for sustainable and socio-economics of human livelihoods and successful global agronomic food systems under climate change. Therefore, this review takes a closer look at the detailed starter fertilizers’ (N, P, and K) placement approaches exploring their implications on crop production cycles and integrating them with environmental and agronomic management practices that could help to tailor the appropriate fertilizer recommendations and minimise fertilizer toxicity. We explored the mechanisms by which fertilizer salt injury and ammonia toxicity interfere with the morpho-physiological and biochemical processes in most agronomic seed crops. Beyond this, we show the advances that have already been made, as well as suggestions and recommendations concerning managing fertilizer salt injuries and ammonia toxicity potentials in the agricultural industry.
