“…The average Pi values of Pb and Cd were 1.30 and 1.10, which meant the studied area was moderately contaminated by Pb and Cd. These two metals, which originate from industrial activities, pesticides and chemical fertilizers, were recognized as economic development signs [ 4 , 15 ]. However, more than 25% of Pb samples showed a considerable level of contamination (Pi > 2), and some Pb samples were already at severe level (Pi > 3).…”

“…Generally, the accumulation of toxic elements will have harmful effects, deteriorating the farmland soil and threatening ecological resources [ 12 , 13 ], and toxic elements can remain in farmland for decades [ 14 ]. Moreover, long-term concentration of toxic elements can also affect human health because they easily transfer into the food chain and can finally accumulate in the human body in a high concentration [ 15 , 16 ]. The toxic elements have different poisoning influence on the human body through their potential effects on the neurological system, kidney function, ossification process and various other organs [ 17 ].…”

The presence of toxic elements in agricultural soils from anthropogenic activities is a potential threat to human health through the food chain. In this study, the concentration of toxic elements in 122 agricultural topsoil composite samples were determined in order to study the current status, identify their sources and assess the level of pollution and human health risk. The results showed that the mean concentrations of Zn, Cu, Pb, Cd, Hg and As in the farmland topsoil were 21.72, 15.09, 36.08, 0.2451, 0.0378 and 4.957 mg·kg−1, respectively. The spatial distribution showed that the soils were mainly contaminated by Cd, Pb and Hg in midwest Jilin but by Cu and As in the east. According to the pollution index (Pi), Nemerow integrated pollution index (PN) and Geo-Accumulation Index (Igeo), Cd and Pb were the main pollutants in the soils. The occurrence of these elements was caused by anthropogenic activities and they were concentrated in the Songyuan-Changchun-Siping economic belt. There is limited non-carcinogenic and carcinogenic health risk to humans. Principal component analyses suggest the Pb, Cd and Hg soil contamination was mainly derived from anthropogenic activities in the Midwest, but all examined toxic elements in the east were mainly due to geogenic anomalies and came from atmospheric deposition.

The study aimed to evaluate the effects of long-term organic and mineral fertilization on soil solution dynamics of nitrogen (N), as well as to understand its relationship with corn plant growth, plant N uptake, and grain yield. The study was conducted in Santa Maria, State of Rio Grande do Sul, Brazil, for 12 years. The treatments consisted of pig slurry (PS); cattle slurry (CS); pig deeplitter (PL); mineral fertilizer (NPK); and no fertilization (control). We determined concentrations of dissolved inorganic N (DIN) and dissolved organic N (DON) in soil solution in situ, prior to sowing and during the growing cycle of corn. In plants, we determined the gaseous exchange, shoot N content, grain yield, and indices of recovery and efficiency of N. DIN in soil solution was the predominant N form in all treatments, ranging from 53 to 80% of total dissolved nitrogen (TDN). NPK was the only treatment that maintained high NO 3-concentration in the soil solution up to 35 days after plant emergence (DAE) and this resulted in higher grain yield. The plants fertilized with CS obtained a recovery of 80% of the N, and promoted improvements in crop growth. The results of this study showed the importance of combining the application of organic fertilizers (before sowing) with mineral sources of N (topdressing), allowing the maintenance of N availability in the soil solution during periods of demand of organic fertilizer.

“…In addition, given massive organic fertilizers made from complex raw materials were applied to agricultural soil in China, a suitable organic fertilizer application guide for cultivation of crops, vegetables or other plants should be established. A balance between the amount of heavy metals input to soils via fertilizer and the amount taken away through planting should be established to reduce the accumulation of heavy metals in soils to ensure the agricultural food safety [22,52] . Table 5 Predicted annual inputs of heavy metals and time to the risk control standard for soil contamination of agricultural land (GB15618-2018) from organic fertilizers applied continuously in China.…”
