Summary: Different types of soil respond differently to biochar amendment, with positive effects observed in sandy soil for soil carbon, nitrogen, microbial biomass carbon, and soil respiration. Biochar application was found to be most beneficial in coarse soil with lower fertility, resulting in significant increases in plant biomass yield.

Summary: Laser micromanipulation can be applied to plant roots grown in transparent soil, enabling controlled dissection of roots and study of light-induced root growth responses. The ability to induce changes in root elongation or complete dissection of microscopic regions of the root is robust to substrate heterogeneity and microscopy set up, showing the potential for a precise and reversible method for root manipulation.

Summary: The study evaluated the effects of soil sulfate supply on soil Ba fractions, plant growth, and Ba and S uptake by lettuce plants. The results showed that sulfate supply decreased the extractable-Ba fraction in soil, alleviated the phytotoxicity of Ba on plants, and enhanced plant growth.

Summary: Agricultural practices can negatively impact the presence and diversity of AMF, while organic orchard management leads to a decline in AMF abundance. Inoculation of AMF can increase lettuce yield but does not significantly alter nutritional quality. Additionally, AMF inoculation does not have a substantial effect on root fungal communities.

Summary: This study aims to find a fertilization method that matches the growth characteristics of vegetables and reduces the environmental problems caused by unreasonable fertilization methods. The exponential fertilization method showed significant improvements in the growth of Lactuca sativa, including increased plant height, leaf length, leaf width, yield, soluble protein content, soluble sugar content, vitamin C content, and elemental nitrogen and potassium content. Furthermore, this method also positively affected soil nutrients after fertilization, indicating its importance for the protection of black soils.

Summary: This study found that root-applied glycinebetaine (GB) can effectively reduce the nitrate (NO3-) content in hydroponically grown lettuce, thereby improving its edible quality. The tested GB application method was also proven to be functional on a commercial scale.

Summary: The purpose of the study was to investigate the risk of consuming vegetables exposed to toxic air pollutants, especially PAHs. The study found comparable PAH concentrations in some of the sampled villages to relatively polluted regions in the world, with biomass burning and fossil fuel usage identified as the major sources of PAHs in rural environments. The study highlighted the importance of analyzing individual pollution sources.

Summary: Tipburn is a physiological disorder that causes leaf discolouration in lettuce and other leafy crops, leading to quality issues for the fresh produce industry. The underlying physiological and molecular basis of the disorder, which is linked to calcium deficiency, is poorly understood. However, a study on vacuolar calcium transporters in different lettuce cultivars found that some genes associated with calcium transport exhibited higher expression in resistant cultivars, providing insights into potential breeding strategies for developing resistant varieties.

Summary: This study aimed to explore the possibility of repairing Cd-contaminated limestone soil and investigate the combined effect of biochar-Sedum plumbizincicola. A pot experiment was conducted to examine the remediation effect of Cd-contaminated limestone soil and Cd absorption by Lactuca sativa. The results showed that the combination of biochar and Sedum plumbizincicola is a feasible strategy that can effectively reduce Cd concentration in Lactuca sativa and remediate Cd-polluted soil.

Summary: The study found that the co-application of biochar and humic substances can increase microbial biomass carbon and respiration activity in soil, with humic substances enhancing most enzyme activities. Aged biochar had a positive effect on plant growth, but also impacted microbial competition for nutrients.
