“…It is apparent that the included phytomorphological traits increase in measure concerning the cultivation period with root and shoot length as the most significant ones (Table 2). This finding adds up to [26,[29][30][31]41], that nitrogen, phosphorus, and chloride which is the form of KCl in this study, are essential to root and shoot primary growth. It has been a known usage of phosphorus is to make root girth thicker [9] but this study proves that a specific concentration of KCl increases root length (Figure 3(a)).…”

“…Tomato is considered of the main crops cultivated in a greenhouse and is demanding in nutrients and water [25]. Leaf chlorosis and wilting of mature leaves are the most common symptoms of potassium chloride in tomatoes on top of blossom-end rot disease [26,27]. Due to an imbalance in water distribution and cell turgidity, root morphology, and leaf chlorophyll fluorescence are affected [28].…”

Potassium chloride (KCl)-induced stress has been predominantly tested on higher crops such as cotton, rice, and wheat. What open agriculture needs now is the extended understanding of possible contributions and detrimental effects of KCl dynamics to tomato as this is one of the major crops consumed worldwide. In this study, the impacts of KCl on the three Philippine tomato (Solanum lycopersicum) genotypes namely, Perlas, Diamante Max F1, and Mica, in separate mesocosms were visualized and measured based on morphological, vascular tissues, and germination variability responses. Three KCl treatments were deployed, which are control (Tc, 0.05 mM), deficit (Td, 0.025 mM), and excess (Te, 0.5 mM), in 3 replicates. KCl-deficit treatment showed improvement in germination rate and vigor index and deteriorated Timson germination index for tomato seedlings. Excess KCl treatment distinctively promotes a higher root (R) to shoot (S) length ratio for Perlas variant with rusty red-orange root color. R/S length increases from control, deficit to excess KCl and R/S fresh and dry weights quadratically increase from control, excess to deficit KCl. The inconsistency of Td and Te treatments to provide equally productive outcomes across the 3 genotypes on the first 37 days after sowing led to the use of 3 bio-inspired algorithms namely, moth-flame, sperm-swarm, and jellyfish swarm optimizers, in determining the most suitable KCl concentration for growth promotion. Multigene symbolic genetic programming was used in constructing the fitness models of five phytomorphological phenotypes namely, root and shoot lengths and weights and leaf count, as functions of KCl concentration and cultivation period. Light microscopy showed that sperm swarm-optimized KCl (0.038 μM) widens the diameter of xylem and phloem vessels in the vegetative stage which is important as they are responsible for transporting nutrients, water, and photosynthesis by-products. Hence, KCl is an essential micronutrient that could alter the growth of crops.

Calcium (Ca) plays a crucial role as a nutrient influencing the ripening, post-harvest duration, and quality of fruits. Its impact on the cell wall and its function as a secondary messenger at the cellular level underscore its significance. While recently there has been an increase in studies examining the effects of Ca on fruit quality, there remains a need to consolidate and expand the literature on pre-harvest and post-harvest applications of Ca concerning the physical-chemical properties of fruits. This review aims to compile information on the mechanisms of Ca absorption by plants, as well as the interaction of Ca with the cell wall in fruit development and growth; the review also aims to synthesize literature on the effects of calcium on the physical and chemical properties of fruits that ultimately influences their quality. The review considers a comprehensive analysis of studies published in reputable scientific publishers (Elsevier, Springer, Frontiers, Wiley, MDPI, Hindawi, SciELO) over the last ten years, encompassing various relevant topics. Calcium proves effective in retarding the loss of firmness in fruits, increasing their mass, mitigating mass loss during storage, and extending postharvest life, thereby enhancing marketability. Furthermore, Ca demonstrates a role in decreasing the activity of enzymes responsible for cell wall degradation. Additionally, it reduces ethylene production in fruits, delaying the climacteric peak and reducing its intensity. Its application results in delayed color changes in fruits. For soluble solids, Ca diminishes sugar values and postpones their peak during the post-harvest period while maintaining high total acidity values. Notably, Ca applications contribute to a decreased incidence of certain physiological disorders.

“…Unlike conventional sludge fertilizers, the mineral elements www.nature.com/scientificreports/ raised in the product are mainly provided by potassium-rich mining waste, which is a slow-release nutrient and requires organic acids secreted by plants or soil microorganisms to be released. Therefore, this product can alleviate plant health problems caused by imbalances in element content, such as calcium and magnesium ion antagonism 42 , tomato blossom-end rot 43 , and crop collapse. On the other hand, this product also improves the long-term potential of the soil.…”

Conventional compost sludge has a long fermentation period and is not nutrient rich. Potassium-rich mining waste was used as an additive for aerobic composting of activated sludge to make a new sludge product. The effects of different feeding ratios of potassium-rich mining waste and activated sludge on the physicochemical properties and thermophilic bacterial community structure during aerobic composting were investigated. The results showed that potassium-rich waste minerals contribute to the increase in mineral element contents; although the addition of potassium-rich waste minerals affected the peak temperature and duration of composting, the more sufficient oxygen content promoted the growth of thermophilic bacteria and thus shortened the overall composting period. Considering the requirements of composting temperature, it is recommended that the addition of potassium-rich waste minerals is less than or equal to 20%.
