Simulation of tomato growth, water and N dynamics using the EU-Rotate_N model in Mediterranean greenhouses with drip irrigation and fertigation

Soto, F.; Gallardo, M.; Giménez, C.; Peña-Fleitas, T.; … - In: Agricultural Water Management 132 (2014) C, pp. 46-59

The EU-Rotate_N simulation model was evaluated with tomato grown in Mediterranean greenhouses to simulate (i) dry matter production (DMP), (ii) crop N uptake, (iii) marketable fresh yield, (iv) ETc, (v) drainage, (vi) NO3− leaching, and (vii) soil water and mineral N dynamics. Crops were grown...

Effect of different nitrogen and irrigation treatments on yield and nitrate leaching of summer maize (Zea mays L.) under lysimeter conditions

Jia, Xucun; Shao, Lijie; Liu, Peng; Zhao, Bingqiang; … - In: Agricultural Water Management 137 (2014) C, pp. 92-103

We examined the effect of different irrigation and nitrogen (N) fertilizer levels on Zea mays L. (maize) on nitrate-nitrogen (NO3−-N) leaching under lysimeter conditions. To do so, we used large lysimeters (2.5m×2.5m×2.0m deep) at the Maize Technological Innovation Center (MTIC) of the...

Evaluation of water movement and nitrate dynamics in a lysimeter planted with an orange tree

Phogat, V.; Skewes, M.A.; Cox, J.W.; Alam, J.; Grigson, G. - In: Agricultural Water Management 127 (2013) C, pp. 74-84

Adoption of high input irrigation management systems for South Australian horticultural crops seeks to provide greater control over timing of irrigation and fertilizer applications. The HYDRUS 2D/3D model was used to simulate water movement in the soil under an orange tree planted in a field...
