Availability of macrocations in perlite and pumice as influenced by the application of nutrient solutions having different cation concentration ratios
(2001)Unused pumice and perlite substrates were placed in 4 litre pots and washed (2 litres per pot) with 2 nutrient solutions differing in the K: Ca: Mg ratio (A = 2.8:3:1, B = 5.6:3:1; ratios on equivalent basis). After ... -
Estimating transpiration rate and canopy resistance of a rose crop in a fan-ventilated greenhouse
(2001)The influence of solar radiation (G) and saturation deficit (VPD air) of the greenhouse air on transpiration rate, canopy resistance was investigated on a soilless rose crop (cv. First Red), grown on perlite, during the ... -
Extension and evaluation of a model for automatic drainage solution management in tomato crops grown in semi-closed hydroponic systems
(2015)In the present paper, a model previously developed to simulate the course of Na+ accumulation in closed hydroponic systems as a function of plant water consumption was further extended so as to be operative also in semi-closed ...
