“…The not significant different N leaching between soil amended with compost, at the end of three experimental years, was reported by Mamo et al [36]. Instead, Santos et al reported the possible compost use as organic fertilizers in the partial substitution of mineral fertilizers, without a significant nitrate leaching risk [37].…”

A three-year study was conducted to test the fertilization properties of different types of compost as the total or partial mineral nitrogen fertilization substitute in an herbaceous crop succession (Zea mays L., Triticum aestivum L. and Helianthus annus L.). Four types of compost (i. green cuttings and depuration sludge, ii. green cuttings, organic fraction of municipal wastes and other organic materials, iii. green cuttings, iv. green cuttings and organic fraction of municipal wastes) and eight fertilization treatments (combining: unfertilized control, 100% mineral fertilization, 100% compost, and 50% compost +50% mineral fertilization) were evaluated in terms of: (i) crop yields and nitrogen uptake, (ii) soil organic carbon and nitrate nitrogen soil contents variation, and (iii) residual nitrate nitrogen leached at the end of the experiment. Maize grain yield ranged from 5.2 ± 1.0 Mg ha−1 to 7.4 ± 0.7 Mg ha−1 with the highest value in the mineral fertilization treatment and the lowest values in the 100% compost fertilization. Wheat and sunflower grain yields were not significantly different among control, mineral, compost, or mineral/compost fertilization treatments with average values of 5.1 ± 0.7 Mg ha−1 and 2.3 ± 0.3 Mg ha−1, respectively. Cumulative crop yield at the end of the three years was not affected by the compost type, but was affected by fertilization treatment (highest values with mineral and 50% compost +50% mineral fertilization). The compost application did not highlight a relevant effect on soil organic carbon. Under 100% of compost fertilization, the crops did not take up a large amount of the N supplied, but it did not generate an increase of NO3-N leaching in the percolation water. Obtained results show the good fertilization properties of compost whereas the amendment property was not relevant, probably due to the low rates applied and the short experimental period.

“…In the context of the current energy crisis and fertilizer prices, the attractiveness of more accessible fertilizer resources in agricultural production processes, such as by-products or waste from various industrial sectors, animal husbandry, or urban ecosystems, is of interest. Pig manure (sewage sludge, pig sludge, manure) is a residual product from pig breeding systems and has drawn the attention of researchers for a long time, both from a technological and management perspective [19,20], as well as as a fertilizer resource [21,22], and from some environmental aspects [23,24]. Pig farming in industrialized systems has been studied from the perspective of environmental issues, by assessing the impact of pig waste associated with soil, water, and crops [25].…”

“…According to various studies, the proper management of pig manure, by fermentation, treatment, pretreatment, and/or filtration, to reduce the content of nitrates, heavy metals, drugs, microorganisms, etc., is an element of the integrated management of these manures to turn them into resources usable in agriculture and to minimize their potential impact on the environment [19][20][21][22][23][24][25][26][27][28]. Among the treatment methods, anaerobic digestion reduces the organic load of the biomass in the absence of oxygen, generating biogas and organic fertilizer.…”

The Potential of Pig Sludge Fertilizer for Some Pasture Agricultural Lands’ Improvement: Case Study in Timiș County, Romania

et al. 2022

In the context of the current energy crisis, pig sludge may be a more accessible fertilizer resource for different categories of farmers and agro-ecosystems, in order to support soil fertility and agricultural production. The present study presents results regarding the influence of pig sludge on soil quality and the spatial and temporal variability of a pasture agro-ecosystem, in the area of Ciacova locality, Timiș County, Romania. The pig sludge was fermented for a period of 6 months in fermentation tanks and was applied at a rate of 80 m3 ha−1 y−1 between 2013 and 2019, on two pasture plots (P808, P816). In the study period (2013–2019), the agrochemical indices studied presented the values: pH = 5.90 ± 0.09 (P816-6-13) and pH = 6.90 ± 0.06 (P808-7-18); P = 10.20 ± 2.26 ppm (P808-4-13) and P = 69.10 ± 3.04 ppm (P808-5-19); K = 176.00 ± 7.44 ppm (P816-4-13) and K = 429.00 ± 7.33 ppm (P816-3-19); NI = 2.45% ± 0.08% (P816-6-13) and NI = 3.87% ± 0.06% (P816-6-19). The variability of the land, i.e., the pasture category, evaluated based on the NDVI index (seven NDVI classes were generated, C1 to C7) decreased under the influence of pig sludge, the values of the variation coefficients being CVNDVI = 17.5098 in 2019 compared to CVNDVI = 41.5402 in 2013 for P808 and CVNDVI = 32.0685 in 2019, compared to CVNDVI = 52.2031 in 2013 for P816. It was found that the land area decreased (2019 compared to 2013) from classes C1 to C4 NDVI (low NDVI values, NDVI < 0.5) and the area increased within classes C6 and C7 NDVI (high NDVI values, NDVI > 0.5).

“…Os melhores resultados foram obtidos para o K, onde a TFi apresentou uma eficiência próxima de 100% no solo LVAd. A maior eficiência de um fertilizante possibilita uma maior absorção pela planta mesmo sob uma menor oferta de nutriente (SANTOS et al, 2018). Microrganismos solubilizadores de K podem ajudar a disponibilizar formas insolúveis que estão ligadas a minerais e silicatos, através da produção de ácidos orgânicos (cítricos, oxálicos, tartáricos etc.)…”

“…A eficiência do N, variou de 40 a 70% para os resíduos compostados e entre 24 e 41%, para os resíduos "in natura" (Figura 4). A eficiência do fertilizante mineral (LVd > 60% e LVAd > 80%) é maior pois o elemento está na forma inorgânica e possui preferência de absorção pelas plantas (SANTOS et al, 2018;ZHANG et al, 2020a).…”
