Dry weight, root length, and nutrient (N, P, K, Ca, and S) uptake. Root length

Dry weight, root length, and nutrient (N, P, K, Ca, and S) uptake. Root length had a sturdy positive correlation with plant fresh weight, leaf location, and nutrient (K and P) uptake. Fresh fresh weight, leaf area, and nutrient (K and P) uptake. Fresh optimistic correlation with plant weight had aasignificantlypositive correlation with nutrient (N, P,(N,and K and S) uptake, and weight had significantly optimistic correlation with nutrient K P, S) uptake, and dry dry weight was drastically correlated with all nutrient absorption, specifically with N weight was substantially correlated with all nutrient absorption, particularly with N uptake uptake (Pearson’s correlation coefficient: 0.849).

Nutrient Use Efficiency beneath Distinct Flow RatesThe nutrient use efficiency beneath various substrate flow prices is shown in Figure four. Figure 4a shows that with an elevated flow rate from 2 to four L/min, the nitrogen useAgronomy 2021, 11,use efficiency (KUE) decreased by 22.0 , when additional intensification with the flow price to six L/min and 8 L/min resulted in increases in KUE by 17.1 and 36.six , respectively. With an increased flow price from 2 to four L/min, the calcium use efficiency (CaUE) enhanced by 45.two (Figure 4d), when with an increased flow price from 4 to 6 L/min, CaUE decreased by 27.six . Additional increasing the flow price from six to eight L/min induced the CaUE 7 of 11 to increase by 76.7 . As is usually observed from Figure 4f, with an improved flow rate from two to 4 L/min, the sulfur use efficiency (SUE) improved by 9.two and further rising the flow price to six efficiency (NUE) decreased in 3.five , when with all the SUE CX-5461 Technical Information values were L/min at all flow L/min resulted in a reduce by the SUE by eight.5 .an increase from 4 to six equivalent and from six to except to get a NUE elevated by 19.three and 26.0 , prices eight L/min, thesignificant 54 improve at eight L/min. respectively.(a)(b)Agronomy 2021, 11, x FOR PEER REVIEW8 of(c)(d)(e)(f)Figure four.
