“…This may have been the cause of greater coffee yield in treatments with stainless steel slag when compared to treatments with limestone. The concentration of some elements in high concentrations in the soil can reduce the production, so a technology to reduce the application of a higher blade is needed to dilute and percolating the excess (Valipour 2012a(Valipour , 2012bYannopoulos et al, 2015).…”

Slags from the iron and steel industry may be used in agriculture to correct soil acidity. Current assay assesses the effect of iron and steel industry´s slag, derived from stainless steel, and compares it to limestone as soil acidity corrective and silicon source in coffee plants. The experiment was conducted between December, 2012 and January, 2014 in the municipality of Machado MG Brazil, in a 4-year-old coffee plantation, cultivar Catuaí Amarelo IAC 30. Experimental design comprised randomized blocks in a 2x4 factorial scheme, with control and four replications. Treatments combined two soil acidity correctives, namely, stainless steel slag ("Agrosilício") and limestone; 4 corrective doses corresponding to 0.5; 1; 1.5; 2 times the amount required to raise index base saturation (V%) of the soil´s surface layer (0 to 0.2m) by 60%. Control did not contain any soil correction. Soil samples were collected during the experiment at depths 0 to 0.1m; 0.1 to 0.2m; 0.2 to 0.4m; similarly, samples of coffee leaves, at 180 and 390 days, respectively, after the application of correctives. Stainless steel slag showed the same efficiency as limestone in soil acidity correction at 0 to 0.1m layer, and in providing Ca 2+ to the coffee plant. Stainless steel slag does not correct soil acidity at 0.1 to 0.2 and 0.2 to 0.4 m layers in coffee plants within a 180 day period. Stainless steel slag increases silicon rates in the soil and in the coffee leaves, and increases yield when compared to limestone.

“…The main vulnerability for a good performance of these crops in the lowlands, in rotation with rice, is the poor natural drainage of these soils (Pinto et al, 2004) owing to the use of horizontal drainage systems. As vertical drainage systems are usually more expensive (Valipour, 2012(Valipour, , 2013, anisotropic drainage systems seem to be the key for sustainable drainage systems in the agricultural areas (Viero & Valipour, 2017), as explored in the present study of the lowlands.…”

A B S T R A C TIn the lowlands of Rio Grande do Sul, land leveling is mostly carried out with no slope for the purpose of rice production. In this environment, soils with a low hydraulic conductivity are predominant owing to the presence of a practically impermeable B-horizon near the surface. Land leveling leads to soil accommodation resulting in the formation of depressions where water accumulates after heavy rainfalls, subsequently leading to problems with crops implanted in succession to rice, such as soybeans. The objective of this research was to quantify the areas and volumes of water accumulation in soil as a function of the slope of land leveling. Five typical leveled lowland areas were studied as a part of this research. The original areas presented slopes of 0, 0.20, 0.25, 0.28 and 0.40%, which were used to generate new digital elevation models with slopes between 0 and 0.5%. These newly generated digital models were used to map the depressions with surface water storage. In conclusion, land leveling with slopes higher than 0.1% is recommended to minimize problems with superficial water storage in rice fields.Drenagem superficial em área sistematizada: Implicação da declividade R E S U M O Nas terras baixas do Rio Grande do Sul, a sistematização é realizada, na maioria das vezes, sem declividade com o objetivo de cultivar arroz. Neste ambiente, são predominantes solos com baixa condutividade hidráulica devido à presença de um horizonte B, praticamente impermeável, perto da superfície. Depois da sistematização, por causa da acomodação do solo são formadas depressões onde se acumula água após a ocorrência de fortes chuvas, causando problemas nas culturas implantadas em sucessão ao arroz, como é o caso da soja. Objetivou-se neste trabalho quantificar áreas e volumes de acumulação de água, em função da declividade da sistematização. Foram estudadas cinco áreas sistematizadas típicas de terras baixas. As áreas originais apresentaram declividades de 0, 0,20, 0,25, 0,28 e 0,40%, sendo que a partir delas foram gerados os novos modelos digitais de elevação com declividades entre 0 e 0,5%. Através dos novos modelos gerados foram mapeadas as depressões com armazenamento superficial de água. A sistematização com declividades maiores que 0,1% são recomendadas para minimizar problemas com armazenamento superficial de água em áreas cultivadas com arroz.

“…Urban systems need to use resources more efficiently, generate more resources within their borders, and diversify sources of water, food, energy, and materials [7]. Good and sustainable governance at a local level requires solid data collection and analytical toolsets for a better assessment of available water resources [8][9], its management [10,11], and flood risks and loss assessments [12][13]. New, integrated approaches for food production and distribution management shall be developed and applied due to suburban arable land declining [14][15].…”

This article presents a discussion about the issue of soil resource management in the context of sustainable development. These resources are one of the basic resources on Earth, conditioning the sustainable development of present and future generations by providing the capacity for food production. The study contains an indicator-based assessment of changes in available soil resources as a result of progressive urbanization processes in the suburban area of a big city. The case study was the Wrocław Larger Urban Zone in Poland. The applied methodology allowed for the valorization of urban sprawl processes on agricultural land. As a result, municipalities were divided into groups that characterize different suburbanization processes and their impact on the available soil resources. By using the proposed approach, it is possible to support the spatial development management process in order to protect the valuable components of the environment. The results of the research show that 29 rural precincts located around Wrocław have a high soil transition index (W≥50), which proves their inefficient agricultural management system on a regional scale. The study is an attempt to answer a question on the practical implementation of sustainable development goals that were included in Agenda 2030.
