“…The drainage parameters of the resulting pH, EC, and percentage of volume of fertigation and drainage are commonly used in the practical control of soilless culture (Gorbe and Calatayud, 2010;Moya et al, 2017;Rodríguez et al, 2015;Urrestarazu et al, 2008). Figure 1 shows a graph of the pH and EC values as a function of the acid dose added to a standard nutrient solution with 2.0 mM bicarbonate from the irrigation water.…”

The effect of pH and silicon (Si) in the nutrient solution on the vegetative development of 2-year-old blueberry plants (Vaccinium corymbosum L. cv. Ventura) was studied. Two independent experiments were performed on coir fiber (CF) and sand as substrates. In experiment 1, Si was applied in the nutrient solution at a dose of 0.0, 0.3, 0.6, and 1.2 mM. In experiment 2, plants were treated with nutrient solution at pH 4.00, 4.75, 5.50, and 6.25, using two sources of acidification: nitric acid and citric acid. The parameters of plant growth, foliar surface, and stem biomass were measured. With the application of 1.2 mM Si to CF, plant height registered a significant increase of 8%, and shoot dry and fresh biomass increased by 21% and 25%, respectively. The results of experiment 1 indicated that the application of Si benefits the vegetative growth of blueberry plants in CF, but no effect was observed in the sand substrate. In the results of experiment 2, the pH level of 6.25 in CF decreased the dry weight of stems and leaves by 21% and 18%, respectively. A significant increase in the pH range of 4.00 to 5.50 was recorded in both the citric acid and nitric acid treatments, but these significant effects were not found in sand. Citric acid presented a similar behavior to nitric acid, which indicates that it can be a good source of acidification in organic and ecologically friendly crops.

The nutrient uptake and allocation of cucumber (Cucumis sativus L.) seedlings at different root-zone temperatures (RZT) and different concentrations of nitrogen (N), phosphorus (P), and potassium (K) nutrients were examined. Plants were grown in a nutrient solution for 30 d at two root-zone temperatures (a diurnally Fuctuating ambient 10 C-RZT and a constant 20 C-RZT) with the aerial parts of the plants maintained at ambient temperature (10 C-30 C). Based on a Hoagland nutrient solution, seven N, P, and K nutrient concentrations were supplied to the plants at each RZT. Results showed that total plant and shoot dry weights under each nutrient treatment were significantly lower at low root-zone temperature (10 C-RZT) than at elevated root-zone temperature (20 C-RZT). But higher root dry weights were obtained at 10 C-RZT than those at 20 C-RZT. Total plant dry weights at both 10 C-RZT and 20 C-RZT were increased with increased solution N concentration, but showed different responses under P and K treatments. All estimated nutrient concentrations (N, P, and K) and uptake by the plant were obviously influenced by RZT. Low root temperature (10 C-RZT) caused a remarkable reduction in total N, P, and K uptake of shoots in all nutrient treatments, and more nutrients were accumulated in roots at 10 C-RZT than those at 20 C-RZT. N, P, and K uptakes and distribution ratios in shoots were both improved at elevated root-zone temperature (20 C-RZT). N supplies were favorable to P and K uptake at both 10 C-RZT and 20 C-RZT, with no significantly positive correlation between N and P, or N and K uptake. In conclusion, higher RZT was more beneficial to increase of plant biomass and mineral nutrient absorption than was increase of nutrient concentration. Among the three element nutrients, increasing N nutrient concentration in solution promoted better tolerance to low RZT in cucumber seedlings than increasing P and K. In addition, appropriately decreased P concentration favors plant growth.

“…Moreover, conditioning the air of the whole greenhouse requires more energy, and is technically more complicated than varying the HNS temperature (Urrestarazu et al 2008). Changes in the root temperature have shown pronounced effects on the uptake of water and nutrients, such as nitrate and phosphate, on shoot growth, yield and quality in melon, watermelon and tomatoes (Cornillon and Fellahi 1993;Gent and Ma 1998;Nkansah and Ito 1995;Urrestarazu et al 2008). Temperatures of the root zone below 18 C and above 28 C can affect the root status by reducing the dry weight, inhibiting its growth and extension and negatively affecting the uptake of nutrients (Bar-Yosef 2008).…”
