The problems faced are uneven football field surface, uneven grass growth, many pebbles and boulders, stagnant and muddy during the rainy season and fractures in the soil during the dry season which make the field not of a good standard for use and have an impact on the incidence of injuries to field users. This study aims to improve the quality of grass for football field using quality local grass <em>Cynodon dactylon</em> in order to overcome the problem of bad fields and avoid field’s users injury. The method is through field rehabilitation technology by improving the surface design and soil media profile as well as the use of quality local grass. The rehabilitation technology includes improving the surface of the field to improve drainage by designing a “<em>geger sapi</em>” shape. The assessment of the rehabilitation results used a qualitative approach with a questionnaire survey to the local community of field users. The results of field grass rehabilitation make the quality of grass in the field after rehabilitation better growth by 45%, perception grass quality was very good by 43%, the surface of the field is flatter, no gravel and surface rocks are found so the flooded were not found by 83%. Field conditions with better grass quality also reduce the frequency of injuries incidents of player during competition about 61%. Hence, field grass rejuvenation benefits the environment and public health. This great benefit will increase the comfort and closeness between the local community.

“…The use of pig sludge has been considered potentially environmentally hazardous if the sludge is not properly treated [26,27], but this can also be considered a positive part of this resource (porcine sludge) under the conditions of an adequate treatment and management technology (physical, chemical, and biological aspects). The use of pig manure after digestion [28] is considered a much more environmentally friendly option. Anaerobic digestion technologies with the addition of various mineral additives are recent considerations to improve the quality of pig manure in order to reduce its impact on the environment [29].…”

“…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.…”

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).

“…Many studies were about the co-digestion of manure and crop residues [26][27][28][29] . In addition, anaerobic co-digestion of manure with straw has been shown to promote methanogenesis making the methanogens community have strong ecological functions and vigorous methanogens [30][31][32] . Also, many researches were about improving methane production by pretreatment or adding some additive.…”

The present study investigated the effects of cow manure ratios mixed with maize stover, rice straw, and wheat stalk at 3, 2, 1 (total solid based, TS-based), respectively, on methane production and microbial community structure during the anaerobic co-digestion process. Results showed cow manure co-digested with maize stover, wheat stalk, and rice straw at ratios of 2, 1, and 3 had the highest cumulative methane yields (272.99, 153.22 167.73 mL/g volatile solid (VS), respectively) and better stability (e.g. pH, volatile fatty acids (VFAs) and their component). The main microbe evolution had a similar trend which was Petrimonas and Methanosaeta in the early digestion process (Days 0-7) and then evolved into Longilinea, Ruminofilibacter, and Methanosarcina with the progress of digestion, but the relative abundance of these microbes in each reactor was different. It was worth noting that Caldicoprobacter in cow manure to maize stover ratio of 2, and to rice straw ratio of three reactors had a relatively higher proportion than reactor of cow manure to wheat stalk ratio of 1, and Hydrogenophaga was the specific bacterium in cow manure to wheat stalk ratio of 1 reactor. In addition, Petrimonas showed positive relationship with VFAs and Longilinea was the opposite. Methanosaeta and Methanobacterium contributed the most during the peak period of methane production in cow manure and maize stover co-digested reactor, and showed positive relationship with acetic acid. However, Methanosarcina and Methanospirillum made a great contribution during the peak period of methane production in cow manure co-digested with wheat stalk and rice straw reactors. These findings could provide further information on the application of cow manure co-digested with crop wastes.
