Stalk composite pipe (SCP), a novel product used for subsurface irrigation, is primarily composed of crop stalks, soil, and water. In subsurface SCP irrigation (SSI), comprehending the effects of burial furrow parameters on soil water movement is critical. However, the precise effects are not known. Here, we aimed to assess the effects of varying b...

In India, drip irrigation with plastic mulch is a common practise for irrigation that conserves water. For the design and administration of irrigation regimes, a thorough understanding of the distribution and flow of soil water in the root zone is required. It has been demonstrated that simulation models are effective tools for this purpose. In thi...

The scientific use of sodium carboxymethyl cellulose (CMC) to improve the production capacity of saline–alkali soil is critical to achieve green agriculture and sustainable land use. It serves as a foundation for the scientific use of CMC to clarify the water and salt transport characteristics of CMC-treated soil. In this study, a one-dimensional s...

We developed an empirical soil wetting geometry model for silty clay loam and coarse sand soils under a semi-permeable porous wall line source Moistube Irrigation (MTI) lateral irrigation. The model was developed to simulate vertical and lateral soil water movement using the Buckingham pi (p) theorem. This study was premised on a hypothesis that so...

The dataset contains seven datasheets with different types of data i.e., cropping system physiological characteristics, radiation intercepting, gross margins, soil nutrient characterization, seasonal physical conditions of the soil, soil water infiltration and seasonal weather conditions. The data will be helpful in assessing how the different plan...

The article provides an overview of studies about the preferential flow phenomenon. This phenomenon is one of the types of the transportation of water solution through the soil profile by preferential channels (pathways) with a relatively high speed and with a slight change in the chemical composition of the solution. Interest in this phenomenon ha...

MIPWA 2.1 gebruikt het onverzadigde zone model CAPSIM van Alterra. Dit model wordt niet meer ondersteund. De opvolger is het model MetaSWAP. Dit model geeft een betere conceptuele beschrijving van de onverzadigde zone, een deel van de uitvoer is makkelijk te bekijken in iMOD en geïnterpoleerde meteorologische data van het KNMI is reeds geschikt als...

Many agricultural areas with humic-sandy and loamy-sandy soils are used also for the extraction of water for drinking-water supply. Model concepts have been developed for the fast preferential transport of plant protection products (pesticides) in such soils, e.g. by fingered and funneled flow. An inventory is given of experiments that may be suita...
