“…Similar results were ensured in our findings where the application of compost in maize plants reduced Cd concentration in shoots and roots and significant increase in and NPK contents [82]. Also, the usage of compost decreased the concentration of cadmium of pak choi cabbage in both roots and shoots in contaminated soils with heavy metals [83].…”

Heavy metals are one of the important environmental pollutants and their toxicity is a great concern for plant growth. Cadmium (Cd) is a toxic heavy metal ion that is accumulated in the soil as a consequence of human activities. Plants own strategies to control the concentration of metal ions inside the cell to minimize the possible harm that could cause by being subjected to nonessential metal ions. However, the accumulation of cadmium concentration in the plant cells led to frail its resistance. In this study, grains of barley (Hordeum vulgare) were exposed to two Cd concentrations (150 and 300 ppm) against untreated control. Cadmium treatment caused a reduction in plant length at the highest level of Cd (300 ppm). The inhibition of chlorophyll content due to indirect Cd effects on the content of essential nutrients and osmoprotectants, including soluble sugars (SS), soluble proteins (SP), total free amino acids (TAA) and higher accumulation in proline contents. Excessive cadmium accumulation increased malondialdehyde (MDA) level in shoot and root systems disrupting the cell membrane. Data of the present study indicated that the usage of banana compost as a biofertilizer alleviated the drastic effect of cadmium stress in barley plants as it promoted growth performance, enhanced photosynthetic pigments, SS, SP, TAA and reduced proline. Banana compost balanced the absorption and translocation of mineral homeostasis from roots to shoots. Results indicated also that compost supplementation reduced lipid peroxidation. Our results may help shed light

This study aimed to find out the use of Bicomat doses and spacing to increase crop production and heavy metal reduction. It was carried out in paddy fields in Karangploso Subdistrict of Malang District from April to July 2022. The study used a Randomized Group Design (RGD), 2 factors and 3 repetitions. The first factor was the dose of Bicomat (B) consisting of B0 = Control (without Bicomat), B1 = Bicomat 10 t ha -1 , B2 = Bicomat 20 t ha -1 , and B3 = Bicomat 30 t ha -1 ; the second factor was the planting distance (P) comprising 3 planting distances of paddy plants: P1 = 20 × 20 cm, P2 = 20 × 30 cm, and P3 = 20 × 40 cm. The observed parameters included the plant height, number of leaves, stem diameter, number of saplings, paddy grain weight per plot, and weight of 1000 paddy grains. While the analyzed heavy metal were Pb and Cu. The results showed that the use of BCH doses increased the growth of paddy plants on all observed parameters. The use of a dose of Bicomat of 10-20 t ha -1 increased the weight of grain and the weight of 1000 grains of paddy. The use of doses of 10 t and 20 t with a planting distance of 20 × 40 cm showed significant growth. The average weight of dry grain obtained at the doses of 10 and 20 t of ha -1 and a planting spacing of 20 × 40 cm amounted to 7.93 and 7.53 kg of plot-1. While in the weight parameter of 1000 grains of paddy, the results averaged out at 32.67 and 34.33 g. The reduction of Pb and Cu metal obtained were 26.23%-58.77% and 56.12%-89.96%, respectively.

“…Roots Cu content was signi cant and negatively correlated with soil moisture content, indicating that C. oleifera root Mg, Fe, Cu and Ca absorption was signi cantly dependent on the total amount of these elements in the soil. Increasing soil moisture content, on the one hand, promoted the release of available Mg, Fe and Ca in the soil, thus improving root uptake [30,31]; on the other hand, this promoted Cu soil xation, leading to Cu absorption reduction [32]. C. oleifera root Mn, Al and Zn contents had no signi cant relationship with soil total Mn, Al and Zn contents, but were signi cant and positively correlated with soil pH.…”

Background Most of C. oleifera forests have low yield and poor quality, largely associating with soil fertility. Soil physical and chemical properties interact with each other to affect soil fertility. C. oleifera growing under different soil conditions affected their yield and oil composition. Three main soil types were selected, and redundancy, correlation, and double-screening stepwise regression analysis were used, for exploring the relationships between Camellia oleifera nutrients uptake and soil physical and chemical properties, shedding light on the transport law of nutrient elements from root, leaves, and kernel, and elaborating the regulation of fruit yield and oil composition. Results In the present study, available soil elements content of C. oleifera forest were mainly regulated by water content, pH value total N, P and Fe contents. Seven elements (N, P, K, Mg, Cu, Mn and C) were key for kernel’s growth and development, with N, P, K, Cu and Mn contents determining the yield traits. The transport characteristics of these nutrients from root, leaves to the kernel were synergistic and antagonistic effects. There were two ways to control the oil production and the content of various oil components: one was to adjust N, P, K, Mg, Zn, Fe and Cu contents of leaves by applying corresponding foliar fertilizers, while the other was to change the soil water content and pH, and apply N, P, Zn, Mg and Ca fertilizers. Conclusion Soil type controlled nutrient absorption by soil pH, water content and total N, P and Fe content. There were synergistic and antagonistic effects on the inter-organ transport of nutrient elements, ultimately affecting the contents of N, P, K, Cu and Mn in kernel, which determined the yield and oil composition of C. oleifera.

Effects of amendments on the bioavailability, transformation and accumulation of heavy metals by pakchoi cabbage in a multi-element contaminated soil

Abstract: The concentration of available arsenic (As), cadmium (Cd), zinc (Zn) and copper (Cu) in CaCl2 extract was effectively decreased by all the amendments, except the available concentration of As was increased by compost–humic acid (T8) in soil.
