claimHemp biochar is compatible with seed germination when mixed with soil as a soil amendment.
claimSeeding hemp into highly compacted soil can cause L-shaped roots, which negatively impacts water and nutrient uptake, according to Adesina et al. (2020) and Amaducci et al. (2015).
measurementHemp is best adapted to well-drained soils with a pH between 6 and 7.5, but can tolerate a soil pH as low as 5.0, according to Amaducci et al. (2015) and Garstang et al. (2005).
claimHemp is capable of phytoremediation, a process where the plant's deep root system absorbs pollutants or heavy metals to detoxify contaminated soils and aid in land reclamation, according to Placido and Lee (2022).
claimTo achieve a negative carbon footprint, hemp biomass must be processed or stored in ways that prevent CO2 from re-entering the atmosphere, such as converting the biomass into biochar, which enriches soil while sequestering carbon, as noted by Adesina et al. (2020).
referenceWu, Y., Trejo, H. X., Chen, G., and Li, S. published 'Phytoremediation of contaminants of emerging concern from soil with industrial hemp (Cannabis sativa L.): A review' in the journal Environment, Development and Sustainability in 2021.
claimHemp requires well-drained soil that retains moisture and does not grow well in wet soils with heavy clay content.
accountHemp was cultivated near the Chernobyl Nuclear Disaster site in 1986 to assist in the decontamination of the soil, as reported by Adesina et al. (2020), Ahmad et al. (2016), and Citterio et al.
claimRecent studies by Linger et al. (2002) and Pietrini et al. (2019) observed that heavy metal contamination in soil has no effect on industrial hemp fiber quality or plant height.
procedureContaminated hemp biomass can be incinerated to reduce it to ashes, which are then safely disposed of in landfills to prevent heavy metals from leaching back into the soil.
Nutrient sensing, signaling and transport in plants - Frontiers frontiersin.org 5 facts
claimIn plants, nutrients absorbed from the soil are transported from heterotrophic roots to seeds via autotrophic shoots or leaves using specific transporter proteins, including channels, carriers, and pumps.
claimIn higher plants, nutrients absorbed from the soil are transported from heterotrophic roots to seeds via autotrophic shoots or leaves using specific transporter proteins, including channels, carriers, and pumps.
claimThe rate of mineral transport through plant roots is primarily dependent on the concentration of minerals present in the soil.
claimMineral ion deficiency in soil acts as a stimulus that triggers a signaling cascade in plants, where interactions between signaling molecules and transporter or carrier genes regulate ion transport.
claimMineral ion deficiency in soil acts as a stimulus that triggers a signaling cascade in plants, where signals perceived by root plasma membrane receptors are transmitted to genetic material to induce the activity of root transporters.

claimIn cases where soil has been stabilized with nonnative species, native species can be added or helped to recover spontaneously while nonnative species are removed to assist the recovery of a native ecosystem.
