“…Ca values for TS1-TS4 were within the optimal range, whereas those for TS5-TS7 were slightly below. In general, Mn, Cu, and Zn concentrations in cucumber seedlings in our study were far lower than the phytotoxic ranges given by Römheld and Marschner (1991) and were within the ranges considered normal for plants (Adriano, 2001).…”

“…Increases in the proportions of DMV and peat while reducing the use of smashed straw helps to improve the response variables for shoot length, root dry weight, and aboveground dry weight, although the lack of this component will increase the BR A response variable. Conversely, the smashed straw, when added in small amounts, will decrease breakage variables (BR B and Römheld and Marschner (1991); normal range given by Adriano (2001). BR A ) for compressed substrates.…”

Compressed substrate is lump and has certain mechanical strength, produced by application of mechanical pressure to the seedling substrates. It will not harm seedlings when bedding out the seedlings, since the compressed substrate and seedling are bedded out together. However, there is no one using the vermicompost and agricultural waste components of compressed substrate for vegetable seedling production before. Thus, it is important to understand the effect of individual components to seedling production, and to determine the optimal ratio of components.

“…Aflizar et al, 2018). High dependence of 'total' soil Cd has been linked to geological substrates, with the highest median concentration being found in alluvial sediments and soils developed on sedimentary rocks (Adriano, 2001;Gramlich et al, 2018). A strong correlation between parental material and Cd content in soils has been previously reported (Smolders & Mertens, 2013;.…”

Cadmium (Cd) levels in cacao products from Santander, the main producing area in Colombia, are well above those permitted for export of cocoa products and may pose a potential health hazard. High Cd in cacao is related to the high content of the metal in beans, which in turn is linked to high concentrations of Cd in soils. Geochemical and petrographic analyses of fertilizer, soil and rock samples from three farms were carried out to determine the sources of Cd and soil characteristics that can affect its bioavailability, in order to identify strategies that may reduce Cd in cocoa. Autochthonous natural sources determine the Cd concentration in soils, with a high correlation between elevated Cd in sedimentary parental rocks and soil metal levels. While no industrial or mining inputs were present, an organic fertilizer was identified as a great allochthonous source of Cd in soils. High levels in the fertilizer were probably due to bioaccumulation of the element, since it was sourced from animals in the same area. The addition of crop waste to fertilize the soil may further contribute bioavailable Cd. Even though the pH range, high OM content and presence of Mn and K all diminish bioavailability, the high metal content in the farm soils still results in significant uptake by the cocoa plants and accumulation in the beans. We suggest that phytoremediation and biological amendments, as well as testing of fertilizers before application, could all be cost-effective solutions to reduce Cd levels in the final product.

“…Cadmium concentrations in agricultural soils are usually lower than 1 mg kg-1. Although due to long-term usage of phosphate fertilizers and sewage sludge, higher records have been identified in many agricultural soils (Adriano, 2001). The standard level of Cd for rice has been suggested as being from 0.2 to 0.4 mg kg-1 the weight of polished rice (Ishikawa, 2005).…”

Heavy metal bioaccumulation in the soil, water and atmosphere may be seriously hazardous to both human and animals with the contamination of food supply chain. Cadmium is a toxic heavy metal with no defined biological function. It is provided to environment mostly through effluent from sewage sludge, mining, burning, industries and fertilization with phosphate. Cadmium uptake and accumulation in rice (Oryza sativa L.) results in negative effect on plant growth. It inhibits physiological activities, such as photosynthesis, respiration, mineral nutrition, and cell elongation, leading to low yield and poor growth. Cadmium damages the photosynthesis system by lowering chlorophyll content and preventing stomata opening. The discrepancy in genotype, cellular distribution, and binding forms of cadmium has a significant role in rice tolerance and cadmium accumulation. Current progress on heavy metals and their interaction with important elements has widely increased our understanding of toxicity in the plants. In this review, the important aspects of cadmium uptake and effects in rice growth, yield, and yield components elucidated.
