“…Nevertheless, the inconsistent and slow effects of these organic amendments could be influenced by the recalcitrant property of charcoal, the raw materials used, and the handling methods. Besides, an unbalanced use of charcoal and sago bark ash can cause heavy metal toxicity, phosphorus fixation by calcium, soil salinization, and environmental pollution [27][28][29]. Therefore, amending soils with the right amount of inorganic liming materials which have relatively high neutralizing values and reactivity is essential.…”

In the tropics, warm temperatures and high rainfall contribute to acidic soil formation because of the significant leaching of base cations (K+, Ca2+, Mg2+, and Na+), followed by the replacement of the base cations with Al3+, Fe2+, and H+ ions at the soil adsorption sites. The pH buffering capacity of highly weathered acid soils is generally low because of their low pH which negatively impacts soil and crop productivity. Thus, there is a need to amend these soils with the right amount of inorganic liming materials which have relatively high neutralizing values and reactivity to overcome the aforementioned problems. Soil leaching and the pH buffering capacity studies were conducted to determine whether the co-application or co-amendment of a calcium carbonate product (Calciprill) and sodium silicate can improve soil nutrient retention and pH buffering capacity of the Bekenu series (Typic Paleudults). A 30 day soil leaching experiment was carried out using a completely randomized design with 16 treatments and 3 replications after which the leached soil samples were used for a pH buffering capacity study. The Calciprill and sodium silicate treatments significantly improved soil pH, exchangeable NH4+, available P, exchangeable base cations, Effective Cation Exchange Capacity (ECEC), and pH buffering capacity in comparison with the untreated soil. The improvements were attributed to the alkalinity of Calciprill and sodium silicate due to their high inherent K+, Ca2+, Mg2+, and Na+ contents. The neutralizing effects of the amendments impeded the hydrolysis of Al3+ (96.5%), Fe2+ (70.4%), and Mn2+ (25.3%) ions resulting in fewer H+ ions being produced. The co-application of Calciprill and sodium silicate reduced the leaching of Ca2+ (58.7%) and NO3− (74.8%) from the amended soils. This was due to the ability of sodium silicate to reduce soil permeability and protect the Calciprill and available NO3− from being leached. This also improved the longevity of Calciprill to enhance the soil pH buffering capacity. However, the amounts of NH4+, P, and base cations leached from the amended soils were higher compared with the un-amended soils. This was due to the high solubility of sodium silicate. The most suitable combination amendment was 7.01 g Calciprill and 9.26 g sodium silicate (C2S5) per kilogram soil. It is possible for farmers to adopt the combined use Calciprill and sodium silicate to regulate soil nutrient retention and improve the soil pH buffering capacity of highly weathered acidic soils. This will enhance soil and crop productivity.

“…Volume of monthly rainfall = Area of the rain gauge in cm 2 × Height of rainfall in cm per month Volume of water required for container with area in cm 2 = (Area of container in cm 2 × Volume of monthly rainfall)/area of rain gauge in cm 2 Leachates were collected and analyzed every five days. After 30 days of the leaching experiment, soil samples were collected, air-dried, crushed, and sieved to pass a 2 mm sieve.…”

“…Soil acidity is one of the world's top five limitations to increasing agricultural productivity [1]. Highly weathered tropical acid soils are characterized by low pH, low organic matter, low in cation exchange capacity (CEC), aluminium (Al), manganese (Mn), and iron (Fe) toxicities, and their macro and micro nutrients deficiencies [2]. The application of nitrogen (N) fertilizers plays an essential part in achieving significant reductions in soil acidity [3].…”

Soil acidity compromises agricultural output in tropical acid soils. Highly weathered tropical acidic soils are characterized by low pH, organic matter, nutrient availability, but high aluminium and iron concentration. Hence, N availability becomes a limiting factor in such soils. To this end, these leaching and pH buffering capacity studies were conducted to determine the effects of co-application of charcoal and sago bark ash on the N leaching or retention and pH buffering capacity of acid soils. The soil leaching experiment was conducted for 30 days by spraying distilled water to each container with soil such that the leachates were collected for analysis. The rate of urea used was fixed at 100% of the recommended rate. The rates of charcoal and sago bark ash were varied by 25%, 50%, 75%, and 100%, respectively, of the recommended rates. The pH buffering capacity was calculated as the negative reciprocal of the slope of the linear regression. The leaching study revealed that the combined use of charcoal, sago bark ash, and urea does not only reduce leaching of NH4+ and NO3− but the approach also improves soil pH, total C, and soil exchangeable NH4+. This effect is related to the fact that the sago bark ash deprotonates the functional groups of charcoal because of its neutralizing components such as Ca, Mg, Na, and K ions. As a result, the combined use of charcoal and sago bark ash was able to retain NH4+ in the soil. The carbonates in the sago bark ash and functional groups of charcoal improve pH buffering capacity. Thus, the combined use of charcoal and sago bark ash improved soil exchangeable NH4+, soil pH, and soil total C, but reduced exchangeable acidity and amount of NH4+ leached out from soil. This study will be further evaluated in a pot trial to confirm the results of the present findings.

“…The most widely used substrates for acclimation of plant tissue culture are organic materials such as charcoal pieces, pine bark, cycas bark, coco-husk, coconut shells, sawdust, sphagnum moss, fern roots, or mineral materials such as perlite and vermiculite (da Silva et al, 2017), which have different properties in terms of water absorption and retention. Charcoal, which is made from plant residues, usually has higher nutrient content and lower water retention, but is capable of controlling acidity (Hamidi et al, 2021). Coco-husk, on the other hand, can absorb water (da Silva et al, 2017) preferable to the others (Wei et al, 2014).…”

“…Charcoal has wide surface, porous structures that retain water but lesser than cocohusk. The selection of medium during acclimation is essential for plant life processes (Hamidi et al, 2021). It is important to understand the characteristics of the substrate in terms of water capacity before administering water and nutrients.…”

Orchids are one of the most favorite cut flowers, flowering potted plants, and have developed into a highly profitable industry. The development of acclimatization method is a necessity for the high survival rate of plantlets. The aim of this study was to investigate the effect of low indole-3-butyric acid (IBA) concentration on faster root formation of Dendrobium hybrid planted on coco- husk and charcoal in a short time. Plantlets derived from the seed culture of Dendrodium milla nayla x Dendrobium striaenopsis were harvested and pre-acclimated, planted on charcoal or coco-husk, and regularly sprayed with 0.25, 0.50, 0.75, and 1.0 mg/L IBA twice a week for one month. The results showed that IBA at 0.50 mg/L provided the most appropriate concentration for immediate root induction and growth of Dendrobium hybrid planted on coco-husk. Root number (1.75) and root length (0.28 cm) showed the highest and the most important indicator of adventitious root induction
