“…A previous study by Krismawati et al (2021) found a strong positive correlation between plant height, number of seeds per cob, seed weight and dry weight of corn due to the application of biochar and inorganic fertilizers. This is supported by Bojtor et al (2022), reporting that the formation of corn is influenced by elements of N, P and K because nitrogen plays a role in photosynthesis, K functions in stem tissue to strengthen stems and leaf formation, while phosphorus contributes to the formation of corn grains, leaves, stems and cobs. The results did not show a correlation between soil and plant parameters, this is presumably because soil parameters, such as physical properties, are more influenced by organic matter, while plant parameters are more affected by the dose of inorganic fertilizer given.…”

The nutrients of plants and the physical condition of the soil must both be considered to increase corn productivity. The continuous use of inorganic fertilizer without manures will cause a decrease in the physical properties of the soil. Therefore, this study aims to obtain doses of organic fertilizer from cow manure and inorganic fertilizers namely urea, KCl and SP-36 that will give the best effect on the physical properties of Alfisols, growth and yield of hybrid corn. The experiment was carried out using the randomized complete block design (RCBD) with two factors namely organic and inorganic fertilizers. Each factor was given at four dosages: 1, ¾, ½ and ¼ of the standard dose each with three replications. Observation parameters include bulk and particle density, soil porosity, aggregate stability, root volume and fresh weight, plant height, as well as the weight of corn with and without husks. The results showed that organic and inorganic fertilizers significantly affected bulk density, soil porosity, aggregate stability, root fresh weight, root volume, as well as the weight of corn with and without husks. Additionally, treatment with 7.5 to 10 tons of organic fertilizer as well as ¼, ¾ and 1 dose of inorganic fertilizers produced the best effect on soil physical properties of Alfisols, growth and yield of hybrid corn, while the lowest results were obtained in the control treatment. This indicates that organic treatment can reduce the use of inorganic fertilizers between ¼ to ¾ of the standard dose.

“…For the proper growth of plants, seventeen elements are required (i.e., C, H, O, N, P, K, Ca, Mg, S, Fe, Zn, Mn, B, Cu, Mo, Cl, Ni) [ 92 , 93 ]. The carbon, hydrogen, and oxygen are uptaken from carbon dioxide and water, while the remaining elements, termed mineral nutrients, are from the soil [ 92 , 94 ].…”

Methods for Rapid Screening of Biologically Active Compounds Present in Plant-Based Extracts

et al. 2022

In recent years, there has been an increased interest in products of natural origin. The extraction procedure of bioactive compounds from plant matrices is a crucial step in the development of useful new bioproducts for everyday life. The utilisation of analyses enabling the rapid identification of the presence of a given group of compounds can be helpful in the early stages of the development of new products in order to save time and reduce costs. Within this article, we have presented a comparison of different, accessible methods for the identification of various bioactive compounds, e.g., saponins, carboxylic acids, oils and fats, proteins and amino acids, steroids, and alkaloids in plant-based extracts. Additionally, the multielemental composition of extracts was also examined. The applied methods allowed for confirmation of the presence of biologically active compounds in bio-products obtained by ultrasound-assisted extraction. At a later stage, these procedures should be supplemented by advanced analytical techniques in order to determine the plant chemicals’ content qualitatively and quantitatively.

“…Achieving food self-sufficiency in Africa requires that N usage increase from 35 kg/ha to 181 kg/ha per year during 2016-2050, although this will be associated with high N losses and low nitrogen use efficiency (57). In maize production, for instance, N application at 120 kg ha -1 is found optimal for yields in SSA, and beyond this application, the N is stored in the leaves and stems, making it very useful for animal fodder (58). However, considering the diversity in the soil types, the optimal rate may vary while Elrys et al (57) admitted that considering several constraints facing the African fertilizer sector, it is impossible to attain the 181 kg N/ha per year application.…”

Fertilizers for food and nutrition security in sub-Saharan Africa: An overview of soil health implications

et al. 2023

Sub-Saharan Africa (SSA) faces chronic food insecurity associated with soil degradation and the peculiar aftermath of climate change and exacerbated by rising population and historically poor agricultural practices. Notably, use of mineral fertilizers has the potential to counteract soil degradation in SSA; it drives an increased agricultural production required to feed the rising population while sustaining the quality and health of soils. However, limited financial resources deprive SSA of the promise of fertilizers, wherein application rates are historically low, and regimes are characterized by unbalanced nutrient composition and poor fertilizer quality. Although current global fertilizer use is generally characterized by low efficiency, SSA is most affected due to the already low usage and the quality of available fertilizer products. About 70% of fertilizer-nitrogen is lost through unregulated transformation to ammonia, nitrous oxide, and nitrate that are either volatilized or emitted into the atmosphere or leached into water bodies. Similarly, the preponderance of fertilizer-phosphorus is lost via run-off and leaching, unavailing it to plants while overloading streams and rivers and, together with nitrate, causing eutrophication. These environmental problems are accentuated in SSA where fertilizer quantity and quality issues are already a limiting factor. Notably, recent advances happening outside of SSA indicate that nutrients, when strategically formulated, such as by nano packaging, (bio)polymer encapsulation, and tunable to respond to environmental cues, can provide multiple outcomes, particularly, healthy soils with higher productivity. Therefore, presumably, a proper synthesis of the gamut of soil properties influencing plant nutrient release and availability, options for plant exposure and uptake is critical for realizing these benefits in SSA. Despite these possibilities, there is a lack of deeper context on fertilizer-related issues as they affect food and nutrition security and the health of soils in SSA. This paper provides an overview of the fertilizer-nutrient and associated agronomic, food insecurity and soil environmental challenges and opportunities, which though not exclusive to SSA per se, can be reasoned with the peculiarity of the region. This provides the impetus to increase fertilizer use efficiency, improve soil and environmental health, sustainable crop production, and food and nutrition security in SSA.
