Mine tailing remediation aims to reduce the rate of sulfide mineral oxidation. Earlier studies showed that photosynthetic biofilms may act as a physical barrier against oxygen diffusion. Currently, a long-term assay (6 months) is required to evaluate the solid phase redistribution of the Pb, Fe, Cu, and Zn originally present in historic and calcareous mine tailing samples (in our case from a semiarid region in North-Central Mexico). The presence of biofilms may provide chemical gradients and physical conditions that shift the proportion of Fe, Cu, and Zn originally associated with oxides to carbonates and organic matter/sulfide fractions.

Long term cattle manure applications build up nutrient pools and can lead to trace element enrichments in soils. The objectives of this study were to evaluate Cu and Zn loadings in the soil during continuous annual cattle manure applications and determine the time required for soil to return to its pre-manure available Cu and Zn levels after manure is discontinued. The manure application rates were 0, 30, 60, and 90 Mg ha-1 for rainfed and 0, 60, 120, and 180 Mg ha-1 (wet weight) for irrigated plots. While manure was applied for 45 years in some plots, applications were terminated in one subset of treatments after 14 years and in another subset after 30 years to study legacy effects after 31 and 15 years, respectively. Soil samples were collected in the fall of 2003, 2008, 2013, and 2018 and analyzed for available Cu and Zn. Crops were grown in all years continuously with Cu and Zn concentrations measured in both silage and grains harvested. The regression model developed using data collected suggests long legacy effects with recovery time to pre-manure levels ranging from 10-20 years for Cu and 23-41 years for Zn at irrigated and 10-24 for Cu and 21-32 years for Zn under rainfed, respectively. Long term applications of cattle manure could lead to accumulation of Cu and Zn, creating long-lasting legacy effects in soils with the increased environmental risk of leaching to groundwater

Effects of long-term applications of high rates of animal manure on plant-availability of nutrients, especially micronutrients, have not been adequately addressed. Our study indicates high rates of P applied via manure do not suppress uptake of Cu and Zn by barley but, at higher than recommended manure rates, uptake of Ca may be inhibited, perhaps through increased salinity. Key words: Feedlot manure, micronutrients, Ca uptake

Cattle and pig manure contain useful mineral nutrients (N, P, and K) and are therefore used as organic fertilizer. However, excessive applications of manure can cause environmental problems and threaten animal and human health because these materials also hold significant amounts of heavy metals, particularly Cu and Zn. To assess the potential risk due to the increased concentrations of heavy metals (Cu, Mn, Zn, and Cr) in a harvested crop, two maize hybrids were grown in pots on four different soils with three different fertilisers (urea, pig manure, and cattle manure). Both soil and manure characteristics influenced the heavy metal concentrations in the plant shoots. Organic fertilisation strongly interacted with the soils and, in general, reduced the shoot content of Cu, Mn, and Zn. A preliminary assessment of the heavy metal balance of the agricultural systems based on the intensive livestock production and maize cultivation showed that the potential soil enrichment of the long-term application of livestock manure arises mainly from the application of pig slurries that have a high content of Cu and Zn. The time required to apply an amount of metal that is equal to the initial soil content is 60–300 years for Zn and 240–450 years for Cu, depending on the soil type and the initial heavy metal content.

To assess the influence of long-term fertilization on weed communities of early and late rice crops, the weed species composition was investigated in experimental plots initiated in 1981 at the Key Field Experimental Monitoring Station of the Reddish Paddy Soil Eco-Environment in Wangcheng, China. The treatments were (1) a control (CK), no fertilizer; (2) N–P, no K; (3) N–K, no P; (4) P–K, no N; (5) N–P–K; (6) N–P–K + Ca, N, P, and K plus lime; (7) N–P + S, N and P plus additional rice straw return; (8) N–P–K + S, N, P, and K plus additional rice straw; (9) N–K + M, N and K plus swine manure. The results indicated that weed flora composition and density were influenced by the different fertilization treatments. Multivariate analyses indicated that changes in the weed community composition were primarily due to soil-available N, followed by light intensity on the field surface, and soil-available P. More weed species and total weed density were observed in the control and P–K plots than in plots in which N, P, and K were applied together. Omission of N application had a greater effect on the weed community than the omission of P or K applications. Nutrients derived from synthetic fertilizers and organic manure or the additional application of lime had no obvious effect on the weed community of late rice crops.

The problem of soil heavy metals (HMs) accumulation from protected cultivation (PC) needs an urgent solution. 132 soil samples from typically high-density PC areas were analyzed for accumulation, risk, and sources of 8 HMs in 16 cities of 8 provinces, China. The soil HMs accumulation characteristics were prominent; Cu, Zn, Pb, Cd, As over-standard (GB 15618-2016) rates reached 15.2, 4.5, 3.0, 27.3, and 2.3%, respectively. The single-factor pollution index indicates that Cd reached slightly contaminated levels in the whole area, while Cu was at a slightly contaminated level only in Yunnan Province. The Nemeiro comprehensive pollution index and the comprehensive quality index suggested that HMs accumulation were at the slightly contaminated levels, with Yunnan province being the most affected and Henan followed. Cu and Zn accumulations are mainly related to frequent input of organic fertilizer, especially livestock manure’s direct return to the field. Therefore, Cu and Zn showed a strong correlation (P<0.01) with soil organic material (SOM), and their available amounts linearly correlated with the extension of planting years in PC. On the contrary, Pb and Cd amounts are only related (P<0.01) to soil texture, and their main sources are related to the parent material of soil formation. Moreover, their available amounts did not correlate with the planting years. Our results suggest that long-term and unreasonable PC may lead to soil HMs accumulation. Therefore, appropriate agricultural materials, planting systems, and fertilization methods must be used to effectively avoid the risk of excessive HMs accumulation in the PC soils.
