“…Water storage at a certain site results from a set of hydrological processes that occur at different spatial scales (Kachanoski & De Jong, 1988). Internal drainage and capillary rise are water flows that occur in the soil volume explored by the crops (Timm et al, 2002;Cruz et al, 2005, Brito et al, 2009, Salvador et al, 2012, Libardi et al, 2015, which are influenced by soil texture, structure and morphology.…”

The knowledge on the temporal stability of spatial variability of soil water storage in the crops’ root zone is of fundamental importance for soil and water management. The objective of this work was to characterize the temporal distribution of water storage in a Latossolo vermelho amarelo and identify field locations with spatial patterns of high, intermediate and low soil water storage, in 13 samplings every 14 days. The assessed period included periods of drying and water recharge of the soil, along which soil water content was determined at 60 sampling points arranged in a 5 × 5 m grid covering an area of 1250 m2 (25 × 50 m). Soil water content was determined by means of a neutron probe, at soil depths of 0.2, 0.4, 0.6, 0.8 and 1.0 m. Soil water storage was calculated by Simpson’s rule and data were analyzed by the temporal persistence of the spatial pattern. Maximum values of soil water storage were obtained at the portion of the area with water flux concentration (sampling points 4, 28 and 57), with and without outliers, and low values of soil water storage were obtained at the highers levels of the site (sampling points 12, 18 and 19), with and without outliers. The sites representing the mean soil water storage were 32, 51 and 11, considering outliers, and 8, 11 and 53, without considering outliers.

“…This region stands out for the great productive potential, particularly with the melon crop (Cucumis melo L.), responsible for 95% of the national production (IBGE, 2016). In regions where the scarcity of water resources prevails in most of the time, special care must be taken with respect to water use and management, since it is a limiting factor in the production of agricultural crops (Libardi et al, 2015). This way, the measurement of the water requirement of a crop should be made, always when possible, based on parameters obtained in situ (Libardi et al, 2015), because they control the availability of water to plants (Hartmann et al, 2012).…”

According to the same authors, changes in the hydraulic soil properties influence the water supply and the consumption by transpiration and, thus, affect the soil water balance.…”

“…Nevertheless, since it is a generalized recommendation for completely different situations, the climatic water balance may not represent the actual conditions of water in the soil, and the greatest disadvantage in this type of balance is the high spatial variability of the climatic components (Libardi et al, 2015). The main component for the determination of climatic water balance is the evapotranspiration, which can be estimated through various physical and empirical models, such as Thornthwaite (Th), Penman-Monteith (P-M) (Bruno et al, 2007) and Hargreaves and Samani (H-S) (Arellano & Irmak, 2016), among others.…”

The correct estimate of the water requirements of a crop, besides favoring its full development, also allows the rational use of water. In this context, this study aimed to evaluate water balance in the soil and estimated through climatic methods for the melon crop. Field water balance was daily determined along a period of 70 days. Climatic water balance was determined based on the reference evapotranspiration estimated by the methods of Penman-Monteith, Thornthwaite and Hargreaves-Samani. It was concluded that climatic methods do not estimate correctly water storage in the soil and, consequently, also the balance. Therefore, they should not substitute the soil water balance method to determine these variables. The water management for the melon crop based on evapotranspiration estimated through climatic methods results in overestimation of the water depth to be applied in the soil, in the initial growth stage, and underestimation in the periods of highest water demand.

“…Portanto, a avaliação do comportamento hídrico de culturas comerciais, além de determinar o consumo médio de água com a finalidade de projetar sistemas de irrigação, determinam-se também os períodos de escassez de água no solo, que são de grande importância para a seleção de variedades e caracterização do potencial de plantio de acordo com a região, buscando minimizar os custos de produção (VIEIRA, 1984). (BRITO et al, 2009;MOTA et al, 2010;SILVA et al, 2014;LIBARDI et al, 2015;ZHANG et al, 2016).…”
