“…Comparisons of the irrigation methods using the clay pots showed that there was a significant difference (p < 0.05) for tomatoes irrigated in rows. The authors [13] infer that water availability was adequate and uniform in the clay pots compared to the irregular availability in the soil for the row-irrigated crops. The cumulative yield of the three vegetable crops irrigated using clay pots were significantly superior (p < 0.05) than crops irrigated in rows.…”

“…Irrigation water was measured and applied using a gauged watering bucket. In the article "Evaluating water productivity of tomato, pepper and Swiss chard under clay pot and furrow irrigation technologies in semi-arid areas of northern Ethiopia" more detail about the agronomic data was presented [13]. A comparative study has been undertaken between bar shaped clay pot and furrow irrigation on tomato, pepper and Swiss chard plots in Mekelle University Campus, Tigray, Ethiopia.…”

The challenge confronted by farmers during prolonged periods of soil water stress is to guarantee the restoration of water and maintain the productivity of agricultural crops. Even in regions such as Amazon, the variability in the precipitation regime should be considered in agricultural planning. There are regions in which 80% of annual rainfall is concentrated between December and June. It is exactly during this period of low rainfall that small-scale family-based farmers need technological assistance to guarantee that their crops remain irrigated in order to maintain their income in this rural environment. The IrrigaPot arises as an alternative that is able to access rainfall that has been stored since the rainy season and provide it to plants when the soil is dry. The pots are maintained full with 20 liters of water, and through capillary action the soil maintains them constantly humid. This technology does not require specific knowledge with respect to irrigation regimes and is necessary for the farmer to dedicate his time to replacing water. The technology is totally automated through a simple system using a float, tubes, and connectors that connect a rubber hose to the lids of the pots buried in the soil.

“…É importante ressaltar que as pesquisas iniciadas com potes de argila no solo foram desenvolvidas a partir de uma parceria internacional entre o Brasil e a África. Resultados exitosos na África pontaram reduções nos custos ao comparar com outras tecnologias de irrigação, além da praticidade na condução do sistema de irrigação, usando potes de argila enterrados no solo (Araya et al 2015;Gebru et al 2018).…”

“…O Projeto IrrigaPote foi fruto de parceria entre o Brasil e a África que instalaram unidades de pesquisa onde foram avaliadas variáveis agrometeorológicas, econômicas e social sobre a agrotecnologia com resultados exitosos (Araya et al 2015;Gebru et al 2018;Martorano et al 2018). No Brasil, o projeto instalou uma unidade de referência tecnológica (URT) tendo como princípio básico o reuso de águas pluviais canalizadas até uma caixa d´água conectada por um sistema de canos que transportam a água até os potes por força gradiente de pressão até os potes, conectados na tampa por canos de borracha, ligados na tampa interna dos potes, contendo boias que controlam a entrada da água, liberando o produtor para desenvolver outras atividades na propriedade rural (Martorano 2020).…”

The objective of this study is to demonstrate the use of infrared thermography in a geoscience context to diagnose thermal and hydrological patterns in soils with crops irrigated using clay pots in western Pará, Amazonia. The thermographic images were obtained in a technological reference unit (URT) installed as part of the IrrigaPote project in the community of Lavras, western Pará. Images were taken in the field and thermal patterns were analyzed for the following targets: T1: Acerola (Malpighia emarginata) trees with leaf litter covering the soil; T2: Acerola trees with no leaf litter covering the soil; T3: Soil with litter cover; T4: Soil with no litter cover, and T5: a backyard agroforest with a large tree over 100 years old with litter covering the soil. The data were stratified into extreme and average values and thermal amplitude, and soil humidity was measured. The near infrared thermography diagnosis and the thermograms were analyzed using the program Flir Tools (6.3v). The thermal targets were randomly selected, with 10 targets for each of the five (05) treatments, for a total of 50 samples. Descriptive statistics were done using a 5% significance level. There were significant differences between exposed soil (T4=61.0°C) and soil covered by litter (T3=43.8°C). The soil shaded by acerola had an average temperature of (T1=33.6°C) and that of the soil shaded but with litter and outside the URT was higher (T2=32.7°C), demonstrating the effects of soil moisture due to irrigation with the clay pots. The lowest temperatures (T5=30.3°C) were found for the large, old tree with the soil covered by litter on the property of the rural producer. The thermal regulation provided by the irrigation using clay pots is in agreement with the Sustainable Development Objectives (SDO), principally SDO 2 with respect to provision of food production during the entire year, and SDO 6, 9 and 12 due to the reuse of rainfall in an agricultural setting, which promotes responsible production, and finally with SDO 13 as a strategy for thermal regulation to mitigate the effects of climate change. Infrared thermography has great potential to be applied to different areas of geoscience.

“…No estudo realizado por Gebru et al (2018) observou-se que havia um número de frutos com peso e rendimento significativamente mais elevados com a prática de irrigação com potes de argilas quando comparados a utilização de sucos convencionais implantados a campo. Este estudo também identificou que o tomate apresentou um aumento na sua produtividade de 32%, quando comparado com métodos tradicionais.…”

The aim of this paper was to present the importance of IrrigaPote for low-cost family farming and its use in the cultivation of vegetables such as tomatoes and bell peppers. The bell pepper (Capsicum annuum L.) culture originates in the American continent, being one of the most produced horticultural crops, presenting various colorations in the pericarp, such as yellow, red, green, orange, cream and purple. The tomato (Lycopersicon esculentum Mill) is the most cultivated solanacea in the world, adopts the short cycle crop and high productivity. IrrigaPote is a low-cost and highly sustainable irrigation technology. This irrigation system was created by the partnership between Brazil and Africa, with this union between Makelle University in Ethiopia and Embrapa Amazônia Oriental (PA). 2013, where the project was developed in Africa, whose principle is to use rainwater and to store it for irrigation with clay pots. In view of the above, it is concluded that IrrigaPote is an important agroecological alternative for low-cost family farmers, and it is feasible to irrigate vegetables such as tomatoes and bell peppers, where the plant absorbs only the amount of water it needs, avoiding the appearance of pests and pests, which occur with excess moisture in the soil and plant caused by conventional irrigation.
