MICRONUTRIENT CONTENTS IN THE PROFILE OF A RECOVERED SOIL WITH SEWAGE SLUDGE AND NATIVE SPECIES OF ATLANTIC FOREST

The use of sewage sludge in agriculture and recovery of degraded areas has been shown as a promising alternative for its final destination. Studies on micronutrient levels after sludge application are necessary to avoid soil contamination at toxic levels. The objective of this work was to verify the micronutrient contents in the soil profile and pH, up to one-meter-deep, nine years after the application of sewage sludge and planting of native species of the Atlantic Forest. The experiment was implemented in a degraded Quartzeneic Neosol and conducted in randomized blocks with four replicates and eight treatments, consisting of six doses of sewage sludge (0, 2.5, 5, 10, 15 and 20 Mg ha-1, with supplementation of potassium due to low concentration in the residue), besides the control treatment, mineral fertilization and only potassium supplementation. After nine years, the contents of all micronutrients evaluated presented a significant response to the application of the treatments, and the application of sewage sludge provided an increase in their contents. Soil pH remained stable at sites receiving mineral fertilization and potassium supplementation. Only manganese and zinc showed mobility in the soil profile. The application of sewage sludge in degraded soil increases the micronutrient content and decreases its movement in the soil profile, and the application of the maximum dose of the residue does not provide toxic levels of these elements in the soil in the long term.

In this work the suitability of several plant species for phytoremediation under natural and artificially installed conditions was studied. Brassica napus, Medicago sativa, Zea mays, Triticum aestivum, and Hordeum vulgare were grown in pots with sewage sludge from Sindos Main WWTP in Thessaloniki and from Sindos Industrial WWTP in Thessaloniki, Greece. The first series of experiments included comparing measurements of various parameters for the above mentioned plants and the sludge to those for control samples (the same plants growing in compost). It was shown that shoot growth was less reduced in T. aestivum and H. vulgare than in the other plant species studied. B. napus had lower germination tax, followed by M. sativa with the lowest germination tax. Generally B. napus, giving less biomass production than Z. mays and T. aestivum, is characterised by a higher ability to accumulate heavy metals like Cd, Cu, Ni, Pb, Zn, Cr, As and Hg. The second series of experiments included comparing measurements of various parameters of B. napus grown in sludge and treated each 7 days with metal solutions of Ni, Zn and Pb containing 10-2mg/l, 10-4mg/l, 10-6mg/l of each metal, to those for control plants treated with double distilled water. Results showed that shoot growth of B. napus were increased at treatments with lower concentrations of metals (10-6 mg/l) and control (treatment with d-distilled water). At the same time uptake of metal ions was increased with the concentration of the solution, i.e. at higher concentrations (10-2 mg/l). It is truly for Pb and Zn, transfer coefficient TC of which (indicates a plant’s potential to concentrate a metal) was quite high 15 % and 7 % correspondingly. It was noticed that B. napus has high ability to accumulate Cr, from the other hand it did not accumulate Ni (at present case).

Different fertilisation systems cause changes in the content of mobile aluminium (Al) forms in the soil as a result of soil pH changes. Long-term stationary fertilisation experiments established in 1996 at 2 sites were evaluated. Experiments consisted of unfertilised control treatment and 6 other treatments, combining mineral fertilisation with the application of farmyard manure, sewage sludge and straw. To record the changes in mobile Al forms, we used 5 extraction procedures with agents: water, CaCl2, KCl, CaCl2/DTPA (CAT) and Mehlich 3 solutions. At treatment nitrogen (N) + straw, topsoil acidification was observed, resulting in the increased content of mobile Al. At treatments with mineral fertilisation (N, NPK), increased content of mobile forms of Al was recorded. Application of cattle manure and sewage sludge helped to stabilise the soil pH and reduce mobile Al forms. The close correlation between the methods determining the exchangeable Al (CaCl2 and KCl solutions) was observed; however, KCl extraction was more favourable in soils of low Al extractability, as the amount of extracted Al was 3–4 times higher. Positive correlations were determined between Al extracted by Mehlich 3 solution and the content of exchangeable Al. The less frequently used CAT method also turned out to be perspective for mobile Al determination. Furthermore, aluminium content determined in Mehlich 3 extract was compared with mobile phosphorus amounts in H2O, CAT and Mehlich 3, respectively. All three investigated phosphorus forms showed significantly negative correlations with Al.

The long-term field experiment with new high yielding perennial energy crop - cup plant (Silphium perfoliatum L.) was conducted in order to evaluate its biomass productivity in Vėžaičiai branch of the Lithuanian Research Centre for Agricultural and Forestry. Experimental site – naturally acid Bathygleic Dystric Glossic Retisol, pH 4.2-4.4. Granulated sewage sludge was applied (at 45 and 90 t ha-1 rates) as an alternative organic fertilizer. The fertilization was done at the beginning of the experiment, prior to cup plant’s sprouts planting in 2013. Each experimental year, traditional N60P60K60 fertilization was performed in a separate treatment. Cup plant’s biomass was harvesting once per season at the end of vegetation. Cup plant’s dry mass (DM) yield substantially increased from 2.80 t ha-1 (in 2014) to 13.41 t ha-1 (in 2016). The use of sewage sludge fertilization was notably superior to that of mineral fertilization for cup plant’s biomass productivity. In all experimental years, the optimal was the application of 45 t ha-1 rate of sewage sludge - in compare with unfertilized treatment (control), DM yield increased by 66 %, on average. Increasing of sewage sludge rate up to 90 kg ha-1 did not give any DM yield supplement. Energy evaluation of growing technology revealed that the application of 45 t ha-1 sewage sludge rate caused the substantial increase of energy output from 1 ha; and on the contrarily, sharply decreased net energy ratio. In order to determine the long-term effects of fertilization on biomass yield, these studies will continue a few more years.

Set Up

The influence of long-term regular mineral fertilization on the soil environment considering the total sulphur and the sulphur balance in the habitat of the permanent mountain meadow was investigated. The experimental field (set up in 1968) is situated at Czarny Potok (20°8’ E, 49°4’ N) in the central part of the Polish Carpathian. With completed annual NPK fertilisation 1.8 kg S/ha was introduced into the soil. The highest sulphur amount was found in the 0–10 cm horizon and this value slightly exceeded the content considered as natural. The sulphur content in the sward from Czarny Potok was lower than the mean sulphur content calculated in Poland for grasses (0.21% S). In the case of full NPK fertilisation the amount of removed sulphur ranged from 11.4 to 14.0 kg S/ha. The mean sulphur leaching into the soil profile from surface of 1 ha can be estimated from 1.1 to 3.7 kg S/ha.

Two Factors

The aim of this work was to identify the most sensitive soil quality indicators and assess soil quality after long-term application of sewage sludge (SS) and conventional mineral fertilization for rainfed cereal production in a sub-humid Mediterranean calcareous soil. The treatments included six combinations of SS at different doses (40 t ha−1 and 80 ha−1) and frequencies (every 1, 2 and 4 years), plus a control with mineral fertilization, and a baseline control without fertilization. Twenty-five years after the onset of the experiment, 37 pre-selected physical, chemical and biological soil parameters were measured, and a minimum data set was determined. Among these indicators, those significantly affected by treatment and depth were selected as sensitive. A principal component analysis (PCA) was then performed for each studied depth. At 0–15 cm, PCA identified three factors (F1, F2 and F3), and at 15–30 cm, two factors (F4 and F5) that explained 71.5% and 67.4% of the variation, respectively, in the soil parameters. The most sensitive indicators (those with the highest correlation within each factor) were related to nutrients (P and N), organic matter, and trace metals (F1 and F4), microporosity (F2), earthworm activity (F3), and exchangeable cations (F5). Only F3 correlated significantly (and negatively) with yield. From these results, we concluded that soil quality can be affected in opposite directions by SS application, and that a holistic approach is needed to better assess soil functioning under SS fertilization in this type of agrosystem.

A long-term assay was conducted to evaluate the environmental impacts of agriculture use of sewage sludge on a tropical soil. This paper describes and discusses the results obtained by applying a interdisciplinary approach and the valuable insights gained. Experimental site was located in Jaguariúna (SP, Brazil). Multiyear comparison was developed with the application of sewage sludge obtained from wastewater treatment plants at Barueri (domestic and industrial sewage) and Franca (domestic sewage), São Paulo State. The treatments were control, mineral fertilization, and sewage sludge applied based on the N concentration that provides the same amount of N as in the mineral fertilization recommended for corn crop, two, four, and eight times the N recommended dosage. The results obtained indicated that the amount of sewage sludge used in agricultural areas must be calculated based on the N crop needs, and annual application must be avoided to prevent overapplications.

Mineral Fertilization

In most Brazilian cities sewage sludge is dumped into sanitary landfills, even though its use in forest plantations as a fertilizer and soil conditioner might be an interesting option. Sewage sludge applications might reduce the amounts of mineral fertilizers needed to sustain the productivity on infertile tropical soils. However, sewage sludge must be applied with care to crops to avoid soil and water pollution. The aim of our study was to assess the effects of dry and wet sewage sludges on the growth and nutrient cycling ofEucalyptus grandisplantations established on the most common soil type for Brazilian eucalypt plantations. Biomass production and nutrient cycling were studied over a 36-month period in a complete randomized block design. Four experimental treatments were compared: wet sewage sludge, dry sludge, mineral fertilizer, and no fertilizer applications. The two types of sludges as well as mineral fertilizer increased significantly the biomass ofEucalyptustrees. Wood biomass productions 36 months after planting were similar in the sewage sludge and mineral fertilization treatments (about 80 tons ha−1) and 86% higher than in the control treatment. Sewage sludge application also affected positively leaf litter production and significantly increased nutrient transfer among the components of the ecosystem.

Adventitious Rhizogenesis

The use of Brazilian native species for ornamental purposes is a promising alternative for local floriculture. Seeking to contribute with new information in this context, the present study aimed to evaluate the rooting performance of mini-cuttings from three Tibouchina species (T. aff. fothergillae, T. heteromalla and T. moricandiana var. vinacea) as affected by the use of indolebutyric acid (IBA) and fulvic acid (FA). Mini-cuttings with 5 cm in length were prepared with plant material from clonal mini-hedges and submitted to different treatments as follows: control treatment (T1); 2,000 mg L-1 IBA (T2); 2,000 mg L-1 FA (T3) and 2,000 mg L-1 IBA + 2,000 mg L-1 FA (T4). Planting was carried out in plastic containers filled with vermiculite, and, after 26 days under greenhouse conditions, the following variables were evaluated: mini-cuttings rooting percentage (RP), roots number (RN), roots length (RL), initial leaves maintenance (ILM) and sprouting (SP). The experiment was conducted under a completely randomized design in a 3 x 4 factorial scheme, with four replications and 20 minicuttings per plot. Rooting percentages were higher than 90% in all three species, regardless of IBA or FA treatments. RP, ILM and SP did not show statistically significant interaction between the treatments. For RN, T2 and T4 promoted the best results on T. aff. fothergillae (12.62 and 14.92, respectively) and T2 resulted in maximum values for T. heteromalla (15.65). For RL, T2 and T4 were statistically superior on T. heteromalla (9.52 and 8.20 cm, respectively). The use of IBA and FA is dispensable for rhizogenesis induction on mini-cuttings from the studied species

Nitrogen Contents

Sewage sludge is a residue from waste water treatment plants and vinasse is a main effluent from alcohol distilleries. The main differences between them are observed in the nitrogen (N) and potassium (K) contents. Sewage sludge is poor in K, and the vinasse in N. This research was carried out to evaluate sewage sludge and vinasse effects on the nitrogen contents of the plant-soil system and the effects of their application on planted-cane and 1st. ratoon-cane under field conditions, on a Typic Haplustox, in Pontal, State of São Paulo, Brazil, using the sugarcane cultivar SP81-3250. A randomized blocks experimental design was used with 13 treatments and three replications. The results were organized in a 3 × 2 × 2 factorial scheme (three residue forms, two application modes and two rates of N or K) and a control treatment (mineral fertilization). Sewage sludge provided the highest N plant contents and the highest residual N soil contents. Sewage sludge and vinasse can replace mineral fertilization for both planted-cane and 1st. ratoon-cane.
