“…Despite the important role of foliar NPK application in terms of rapid assimilation and translocation and the positive influence on growth and yield, foliar fertilization cannot replace nutrition through the roots;. however, it can be used to reduce the use of fertilizers on the soil [116]. To overcome this problem, the use of organic amendments such as adding vermicompost plus applying foliar nano-NPK in the calcareous soil conditions is a good practices that can improve the growth; pod, seed, and fixed oil yield; and fatty acid content of the Moringa oleifera trees.…”

A shortages of soil nutrients resources and a lack of accessibility to them especially in calcareous soil are considered some of the main factors that limit plant production. In particular, the cultivation of the Moringa oleifera trees in this type of soil is of special interest given the increasing demand for every part of this tree. Several studies have focused on the production of its leaves as an herbaceous plant and not as a tree, but there has not been extensive research on its pods, seeds, and fixed oil production. In this sense, in this study, we provide an assessment of the use of fertilizers, vermicompost and NPK (as traditional minerals and as nanoparticles), in order to improve pods, seeds, and fixed oil contents, as indicators of the quality of the production of the Moringa oleifera trees in calcareous soil conditions. In this experiment, it was observed that all parameters and the yield of pods, seeds, and fixed oil of the Moringa oleifera tree were significantly improved by increasing the level of vermicompost and using NPK fertilization and combination treatments in both seasons of the study. The combination treatments of 10 and 20 ton ha−1 vermicompost plus NPK control produced the highest percentage of oleic acid with insignificant differences between them.

“…It may be an effective strategy to address the low bioavailability of phosphorus in soil and for the immediate improvement of nutritional stress (Goos and Johnson, 2000;Dixon, 2003;Maltais, 2006;Girma et al, 2007). Several studies have shown that the use of foliar fertilization cannot be an alternative method to root fertilization, but rather complementary (Ling and Silberbush, 2002;Mengel, 2002;Toscano et al, 2002;Pandey et al, 2013).…”

Background: P deficiency is very common in alkaline - calcareous soil. Therefore, application of foliar-absorbed fertilizers may be an effective strategy to overcome the low bioavailability of phosphorus in soil, by improving phosphorus use efficiency and reduced nutrients loses.Methods: A field experiment was carried out in 2006-07 growing season at El-Menia (southeastern Algeria) to evaluated the effect of two foliar P (agriphos and leader-start) and three soil P (TSP P 46, Fosfactyl NP 3:22 and NPKs 8:36:13,5+15) on yield and P use efficiency of durum wheat crop Triticum durum Desf. var. Carioca and on available P and total P in soil.Result: Data showed that significant effect of soil P fertilizer on grain yield components (ears m-², grains ear-1 and the 1000 grains weight), grain P use efficiency and available P in soil. The best values were recorded by NPKs fertilizer, but no differences were observed for these parameters among foliar fertilizer sources.

“…For instance, clay soils typically have a high K-fixing capacity and thus, often show little response to soil applied K fertilizers because much of the available K is quickly fixed to the clay particles (Brady and Weil, 2002). Therefore, K foliar fertilizer applications are considered as a valid alternative in order to provide nutrients to plants when soil conditions may limit root uptake or during periods of fast growth when nutrient needs may exceed root supply (Swietlik and Faust, 1984;Toscano et al, 2002). In addition, as a rule, fruit trees have a deep rooting system, which limits the efficiency of fertilizers applied to the soil surface (Mengel and Kirkby, 2001).…”

Olive (Olea europaea L.) plants were sprayed (one, two or three times) with nutrient solutions containing KCl, KNO 3 and K 2 SO 4 with the same amount of K (0, 1, 2 and 3% w/v). The weight of the plants was unaffected by salt type, number of sprays or K concentration of salts, whereas the dry matter percentage was significantly increased in the plants treated with K 2 SO 4 . Furthermore, the application of K 2 SO 4 led to a significantly higher N concentration in leaves than that of KCl. K-salts increased K concentration in plants in the following order: KCl> KNO 3 > K 2 SO 4 and three foliar applications were significantly more efficient than one. Moreover, irrespective of plant part, K spray application frequency significantly affected Fe and Zn concentrations in the plants studied. Finally, although KCl increased Cl concentrations more than KNO 3 and K 2 SO 4 , the former fertilizer was the most efficient to improve the K status of the olive cv. Chondrolia Chalkidikis.
