“…Inorganic N content (sum of NH4 + , NO3 -, NO2 -) of the biosolids was 1.008 g kg -1 , which represents an important contribution of mineral N that could be reflected in the volatilization of N as NH3. These reported values for the different parameters in biosolids coincide with those reported in other studies (de Melo W et al, 2018;Medina-Herrera et al, 2020).…”

“…Within a period of 90 days of incubation, Rojas-Oropeza et al (2010) reported values above 63% of NH4 + present in the biosolid added to the soil. The detriment of NH3 by this mechanism may be due to different causes: 1) high soil pH, which increases the concentration of free NH3; 2) environmental conditions such as soil aridity or moisture, high temperatures, soil texture; and 3) low soil cation exchange capacity (de Melo et al, 2018;Rigby & Smith, 2014). In all treatments, the pH was maintained at values of 6.5 to 7.3, which are considered neutral, so the effect of pH for the release of free NH3 is negligible.…”

Short-term amendment of biosolid on agricultural soil: effects on C and N mineralization and microbial activity

Adding biosolids to agricultural soils can improve its quality through increased storage of C and N. A study to analyze the short-term impact of the addition of biosolids on the release of nutrients and the microbial activity in agricultural soil was carried out. The microbial biomass C (MB-C), urease activity (UA), and mineralization of N and C at different application rates of biosolids were evaluated (0 mg, 100mg and 200 mg of N-NH4+ kg-1). In addition, a biosolid-only treatment was tested. It was observed an increase in C and N mineralization, NH3 volatilization, and MB-C content, according to the application rate of biosolids. In biosolid treatments, UA increased 100% on average in the first seven days of incubation. These results suggest that the nutrient content in the soil is improved and microbial activity is positively stimulated.

“…Segundo os autores (Melo;Carvalho, 2018) o maior consumo de concreto, aço e forma no método de concreto armado se explicam pela concepção do método, onde utiliza-se estes materiais na concepção dos elementos portantes, ao contrário da alvenaria estrutural que utiliza as paredes compostas por blocos estruturais como elemento da mesma categoria.…”

“…Pela necessidade de ter menos etapas, a alvenaria estrutural apresenta uma grande vantagem na utilização da mão de obra, tanto em tempo de execução, por apresentar um melhor equilíbrio das horas úteis de trabalho entre os ajudantes e o pedreiro, quanto em custo, por necessitar de menos etapas que exigem profissionais especialistas como armador e carpinteiro (Melo;Carvalho, 2018).…”

No presente artigo será abordada a construção com alvenaria estrutural, método este que garante maior economia e menor tempo de obra. O trabalho em questão utiliza-se de uma pesquisa bibliográfica e de uma narrativa exploratória que busca descrever, discernir e explicar da forma mais clara e sucinta o tema proposto. Há uma busca comparativa com métodos mais difundidos e utilizados para que se mostre a real importância e necessidade do que se aborda no artigo. Chama-se de alvenaria o conjunto de peças justapostas coladas em sua interface, por uma argamassa apropriada, formando um elemento vertical coeso. O objetivo central desse projeto é analisar e estimular a utilização de tal método construtivo e trazer novos conceitos de construção mais rápida e econômica em obras que demorariam meses ou até anos para serem executadas. Além dos benefícios intrínsecos à função, a alvenaria de blocos de concreto, quando tratada de forma adequada, proporciona vantagens significativas no processo de racionalização da construção quando comparada a outros processos mais tradicionais. Não há neste artigo, a obrigatoriedade de se fazer uma comparação mais enfática e enérgica entre todos os métodos de construção. O que há, de fato, é uma tentativa de se apresentar um método alternativo de construção que busque novas tecnologias, novos investimentos e aumente o leque de novas práticas de obras e novos meios de alcançá-los de forma mais rápida e econômica.

“…The surface charge properties are strongly correlated with other soil processes such as the formation of soil structure and other organomineral complexes, movement of ions and water in the soil, plant nutrition, and the swelling, flocculation, dispersion, and shrinkage of the soil fractions [7] whiles soil chemical attributes such as EC, pH, etc. also affect the functions, productivity, and fertility of the soil [8][9][10]. Previous studies [11,12] reported that organic matter contents, clay mineralogy, particle size distribution, pH, and land-use activities are important intrinsic and extrinsic features that greatly affect surface charge properties.…”

Innovative agricultural technologies such as organic fertilization have provided long and short-term benefits as far as sustainable soil management is concerned. In this study, five treatments were applied: cow manure (CM), chicken manure (JM), poplar tree leaves (TL), maize straw (MZ), and control (CK). The aim was to evaluate the long-term effects of applying organic materials on soil chemical and electrochemical properties. The highest pH and EC were recorded in JM and CM respectively. The highest cation exchange capacity (CEC) and specific surface area (SSA), were recorded in treatment TL while the application of organic materials increased the CEC and SSA by 24.9-85.5% and 6.9-52.4% respectively. The surface charge characteristics were significantly improved by the organic treatments compared with CK (P<0.05). The application of organic materials increased the surface charge potential (φ0) by 28-35.9% and the surface charge density (σ0) by 21.42-35.71%. Moreover, the electric field strength (E0) and surface charge number (SCN) were increased by 16.6-27.8% and 21.7-94.9% respectively. The soil chemical and electrochemical properties decreased along the soil profile with the exception of pH and EC, which increased with depth. The granulometric properties of organic matter and other physical attributes affected the chemical and electrochemical properties of the soil. The surface charge characteristics were significantly positively correlated with each other and the soil chemical properties as shown by the correlation analysis. The application of organic materials especially treatment TL is recommended as it had a more advantageous effect on enhancing the surface charge characteristics and could improve the quality of agricultural soils.
