Sewage sludge from treatment plants is an important source of N and organic matter for agriculture. The objective of this study was to analyze the effect of sewage sludge and mineral fertilization on the soil chemical properties and production of five pineapple cultivars. The study was conducted in 2 x 5 factorial scheme, consisting of two different fertilizers (sewage sludge and mineral fertilizers), combined with five pineapple cultivars (‘Pérola’, ‘Vitória’, ‘Smooth Cayenne’, ‘MD-2’, and ‘IAC Fantástico’). Sewage sludge fertilization favoured soil fertility by promoting a decrease in the pH and increase in the content of soil organic matter, phosphorus, calcium, iron, and zinc, compared to soil with mineral fertilization. In pineapple plants, sewage sludge fertilization provided statistically similar yields and physic chemical fruit characteristics compared to mineral fertilization. Among cultivars, the ‘Smooth Cayenne’ presented the highest yield (125 t ha-1), followed by cultivars ‘MD-2’ and ‘IAC Fantástico’, with intermediate yields of 98 and 90 t ha-1. Cultivars ‘Pérola’ and ‘Vitória’ presented lower yields. In this context, it was observed that sewage sludge can be used in pineapple cultivars, as an alternative source of nutrients to partial replaces inorganic fertilization.

The dependence of mineral fertilizers, increasingly, has brought concern facing the increased demand and because it is a non-renewable mineral resource. The organic fertilization, exclusively, it is impractical in large scale, however, the combination of organic and mineral sources have already proved to be feasible, both from the point of view of nutrition of plants as well as in the aspect of recycling of urban and industrial waste by agriculture. This research had as objective to determine the efficiency of aorganomineral fertilizer formulated on the basis of sewage sludge in substitution of mineral fertilizer in the cultivation of sugar cane in environments with different levels of soil fertility. An experiment was conducted in greater soil fertility, in the Institute Federal Goiano– Campus, Morrinhos-GO, Brazil. The other, less soil fertility, was implanted in the ethanol industry Tijuco Valley, located in Rio do Peixe, district of Prata-MG, Brazil. The experimental design was randomized blocks in a factorial 5 x 2 +1 being five doses, with and without a biostimulant plus an additional with mineral fertilization, in four replications. The doses were in function of fertilization recommendation of planting and coverage for each environment, consisting of: 100 % of the mineral source and percentage 0; 60; 80; 100 and 120 % of organomineral fertilizer. We evaluated the productivity, tillering, diameter and height of stem in Prata-MG the different percentages of the fertilization of planting favored and increased productivity, height and stem diameter of sugar cane; the use of biostimulants not contributed to increase crop yield. In Morrinhos-GO, the different percentage of planting fertilization did not increase the productivity, tillering, height and diameter of the sugarcane stem; the use of biostimulants increases the productivity yield of sugarcane. Organomineral fertilizer based on biosolids is similar to fertilization with mineral fertilizer in environments.

Composted Sewage Sludge

Naturally infertile soils require large amounts of mineral fertilizers to obtain the desired crop yield. In the Cerrado region of Brazil, there is a need to investigate the potential of organic fertilizers to sustainably increase crop productivity and food security. A field study was conducted over two experimental seasons to evaluate the agronomic effectiveness of composted sewage sludge (CSS) as a fertilizer for soybean cultivation in infertile tropical soils. A 4 × 2 + 2 factorial randomized complete block design was applied with the following treatments: (i) CSS: 5.0, 7.5, 10.0, and 12.5 Mg ha−1 on a wet basis applied according to two different methods: whole area (WA) or between rows (BR); (ii) comparison with two alternative treatments: a control with no CSS and mineral fertilizer application, and an area treated with conventional fertilizers only. All the treatments were compared in terms of micronutrient concentrations in surface soil and plant leaves, plant development, crop productivity, and yield. Bi- (ANOVA, correlation matrix, and polynomial regression analysis) and multivariate (PCA, principal factor analysis) statistics were applied to determine statistical differences and relationships/observed variability among the treatments. Results showed that at higher CSS-WA rates: (i) soil and leaf micronutrient concentrations increased; (ii) there was an increase in soybean yield by 12 and 20%, respectively, as compared to control and conventional fertilization; (iii) soybean yield was 67% higher than the mean soybean yields for Brazil. Research outcomes confirm the benefits of CSS application on infertile agricultural soils in the Cerrado region, representing a strong alternative source of micronutrients in the CSS with respect to conventional fertilizers.

<p>Biochar application is now considered to be one of the most promising agricultural practices to mitigate climate change. However, to fully assess the benefits of biochar, we still need to better understand its effects on soil properties, and particularly on native soil organic matter (SOM) dynamics.</p><p>In this work, we investigated soil respiration and changes in SOM pools (mineral-free, intra-aggregate, and mineral-associated SOM) as affected by the application of 20 t / ha per year of biochar alone or combined with mineral fertilizer, municipal solid waste compost, or sewage sludge. The experiment was run for 7 years in a semiarid agricultural soil. We found that biochar had no effect on soil respiration with respect to mineral fertilization and no amendment (control), and tended to decrease CO<sub>2 </sub>emissions from soils amended with municipal solid waste compost and sewage sludge. Biochar accumulated mainly in the mineral-free SOM fraction and its addition, especially in combination with municipal solid waste compost, promoted the amount of SOM occluded with aggregates and associated to mineral surfaces.</p><p>Acknowledgments: to the Spanish MICINN (MINECO, AEI, FEDER, EU) for supporting the research project AGL2016-75762-R.</p>

Fertile agricultural land encourages people to carry out agricultural cultivation activities. But in general, it has decreased soil fertility because its managed intensively without recycling of organic matter and has an impact on decreasing soil fertility chemically such as soil organic carbon and pH then leads to low productivity. Soybean is an agricultural product that necessary to develop because the demand for soybean consumption in East Java Province has always increased. However, Indonesia has not been able to fulfil this demand. One of the technology innovations that can be applied to improve soil fertility that has low organic matter and to increasing soybean production by providing input of quality organic fertilizer in the form of compost (Tithonia and Cow Dung). So this research is important to determine the effect of application cow dung compost and tithonia on soil chemical properties, the growth of soybean crops, and the correlations between soil chemical properties and soybean growth. This study used a randomized block design with 6 treatments and 3 replications. The result showed that the application of tithonia and cow dung compost shows a significant effect on soil chemical properties, plant height, and the number of leaves, but didn’t show a significant effect on the number of branches in every observation. Based on the correlation analysis, the results show a positive correlation between soil chemical properties and soybean growth.

One of the largest strawberry-producing municipalities of Rio Grande do Sul (RS) is Turuçu, in the South of the State. The strawberry production system adopted by farmers is similar to that used in other regions in Brazil and in the world. The main difference is related to the soil management, which can change the soil chemical properties during the strawberry cycle. This study had the objective of assessing the spatial and temporal distribution of soil fertility parameters using principal component analysis (PCA). Soil sampling was based on topography, dividing the field in three thirds: upper, middle and lower. From each of these thirds, five soil samples were randomly collected in the 0-0.20 m layer, to form a composite sample for each third. Four samples were taken during the strawberry cycle and the following properties were determined: soil organic matter (OM), soil total nitrogen (N), available phosphorus (P) and potassium (K), exchangeable calcium (Ca) and magnesium (Mg), soil pH (pH), cation exchange capacity (CEC) at pH 7.0, soil base (V%) and soil aluminum saturation(m%). No spatial variation was observed for any of the studied soil fertility parameters in the strawberry fields and temporal variation was only detected for available K. Phosphorus and K contents were always high or very high from the beginning of the strawberry cycle, while pH values ranged from very low to very high. Principal component analysis allowed the clustering of all strawberry fields based on variables related to soil acidity and organic matter content.

Sewage sludge refers to a nutrient-rich by-product and organic matter from treatment plants and has become a challenge for many research segments to find a rational and sustainable destination for this material. In this context, the carbonization of biomass (by the pyrolysis process) results in biochar, characterized by a very stable material with specific physical and chemical properties and can represent a very important tool for this challenge. Thus, the objective of the present work was to transform, bypyrolysis process, small portions of the biosolid generated in Rancharia ETE into biochar. In addition, both the biosolid and the generated bicarbons were subjected to physical, chemical and structural analyzes in order to proceed with their respective characterization. From the analysis, it was found that the treatment submitted to temperature of 550°C as the best option for possible applications.Keywords:biosolid; pyrolysis; biochar.

Soil Fertility Status

Organic materials in situ remaining paddy crops in paddy fields are much abandoned by farmers. Most of the remaining harvested are burned, stacked in the cultivated, or used for animal feed or as a fungus. Straw compost is source of Potassium (K) and Silica (Si). About 80% of K absorbed by plants is in the straw. The return of straw to the soil may slow the impoverishment of Potassium (K) in the soil. This study aims to find out how the availability of phosphorus (P) and potassium (K) nutrients by giving organic matter as soil fertility status in paddy fields in Beringin Subdistrict, Deli Serdang Regency and to review management alternatives that are in accordance with the soil fertility status in the Central Land Rice fields in Beringin Subdistrict, Deli Serdang Regency. This research was carried out in the Central Rice Field in Beringin Subdistrict, Deli Serdang Regency ± 11 meters above sea level. The taking of soil samples was taken in the upper layer at the top soil depth of 0-20 cm, 20-40 cm and the coordinates were recorded using GPS (Global Positioning System). While information on land management is obtained by direct observation in the field and in-depth interviews with farmers in snow ball which aims to obtain complete information from farmers. Soil samples that have been taken in the field are then analyzed in the laboratory. Soil chemical properties analyzed in laboratory soil chemical properties analyzed at P2O5 Bray II (ppm) laboratory K2O Hcl 25% (mg / 100g).
