“…Thus, the results indicate, for the experimental conditions, that the soil covered with a biodegradable blanket and the soil covered with straw loses less soil and water, similar to those obtained by Lima et al (2020), where the mulch acted as a sink for the kinetic energy of rain, reducing runoff and soil losses, in addition to retaining water in it, therefore absorbing and intercepting rainwater.…”

“…Among the initiatives related to the investigation of soil and water losses caused by water erosion in arable areas, the work carried out by Martins et al (2010), who quantified soil losses at different stages of eucalyptus crop development, determining the C factor, which represents the effect of cover and soil management. According to Lima et al (2020), the use of soil cover in semi-arid regions promotes greater moisture retention, reduces the direct incidence of sunlight on the soil and temperature fluctuations, providing high root production, higher growth rate, and productivity of the aerial part, in addition to fulfilling the role of controlling water erosion, with the reduction of values of the surface runoff. Concerning biodegradable blankets, it is necessary to carry out work to assess their effects on increasing plant productivity and controlling erosion.…”

The current hegemonic agricultural model, which is based on the green revolution, is intrinsically related to environmental and social impacts, such as erosion, desertification, and abandonment of agricultural areas. Thus, the objective of this study was to evaluate the loss of soil and water through runoff during a simulated rainfall event, testing the efficiency of different types of coverings on beds with watermelon crops, inferring that in relation to soil loss, this was greater in uncovered soil. Therefore, it should be observed that this work has applicability in the choice of efficient soil management techniques, to minimize the effects of erosion and, consequently, the environmental impacts as a result of agricultural activities. The results obtained showed a loss equivalent to 72.72% of the total for bare soil, which means a greater sedimentation of the soil, while for soils covered with corn straw and the biodegradable blanket, a loss of 19.70% and 7.58% of the total were observed, respectively. Surface water runoff, with the use of corn straw and the biodegradable blanket, was reduced by 81.22% and 67.42%, respectively. It was concluded that soil cover is effective in controlling water erosion.The current hegemonic agricultural model, which is based on the green revolution, is intrinsically related to environmental and social impacts, such as erosion, desertification, and abandonment of agricultural areas.

“…Mulching provides greater hydraulic roughness, increasing water infiltration into the soil and reducing surface runoff velocities and, consequently, soil losses. This protects the soil surface from the direct impact of raindrops, thereby reducing surface crusting, compaction, splash erosion and water evaporation and controlling soil temperature fluctuations, particularly during dry periods (e.g., [1][2][3][4][5][6][7][8]17,[20][21][22]27,39]).…”

“…Among the different organic materials used as mulch, coconut coir dust, a by-product from the coconut (Cocos nucifera L.) industry, is known to be efficient in controlling runoff and soil loss (e.g., [17,20,38]). Coir is an inexpensive, highly durable natural fiber that biodegrades slowly.…”

The semiarid is characterized by extreme heat, which affects agricultural production by limiting the soil's ability to retain water. The objective of this study was to investigate the influence of mulch on soil temperature and soil moisture in a drip irrigated banana plantation in a Brazilian semiarid region. Six thermocouples and three soil moisture probes were used, with coconut coir as mulch. Daytime and nighttime surface temperatures were compared for two mulch densities (4 and 8 t ha-1) and bare soil. Soil temperature and moisture were measured at three depths (0.1, 0.3 and 0.5 m). The study was conducted from November 2014 to March 2015. Mulch had a buffer effect on soil temperature fluctuation. Drip irrigation management associated with mulch provided a uniform moisture profile close to field capacity.

“…O nordeste do Brasil apresenta excelentes condições para o cultivo da moringa, sendo essa a região que tem o maior cultivo e utilização dessa planta (Lima et al, 2020) Devido às condições edafoclimáticas da região semiárida apresenta dificuldade na oferta de alimento e de água potável. Portanto, é interessante estudos de espécies que sejam resistentes às condições de restrição hídrica e que apresentem diversos usos.…”

Moringa oleifera é uma planta de usos múltiplos, seja utilizada como alimentação humana (flores, folhas, frutos e sementes) e animal (produção de forragem), tratamento de água para consumo humano, indústria de cosméticos e medicinal, combustível e produção de papel. É considerada uma espécie arbórea exótica que se adaptou às condições edafoclimáticas do semiárido do nordeste brasileiro, embora a ocorrência de déficit hídrico reduza o crescimento, limite o desenvolvimento e comprometa a fisiologia da planta. O silício é um agente mitigador do déficit hídrico. Objetivou-se com o presente estudo, avaliar o efeito das doses de silício na indução à tolerância da Moringa oleífera ao estresse hídrico, sobre o crescimento vegetativo. O estudo foi desenvolvido em parceria com o Centro de Ciências Agrárias e Ambientais da Universidade Estadual da Paraíba, localizado no município de Lagoa Seca – PB. O experimento foi instalado em delineamento de blocos ao acaso, em parcelas subdivididas em esquema fatorial duplo 5x5, sendo cinco lâminas de irrigação (25, 50, 75, 100 e 125% da Evapotranspiração da cultura) e cinco de doses de dióxido de silício (0, 3, 6, 9 e 12 g de dióxido de silício por planta), totalizando 25 tratamentos com quatro repetições, com 100 unidades experimentais as quais eram constituídas de três plantas úteis. Nas parcelas ficaram as lâminas de irrigação e nas sub-parcelas ficaram as de doses de dióxido de silício. As lâminas de irrigação exerceram influência significativa em todas as variáveis de crescimento estudadas.
