“…This may enhance Mo availability in soils and to crops (Anonymous, 1979;Rileyetal., 1987). Application of P fertilizer may also increase Mo availability in soils, owing to its competition with MoO 4 2 " for adsorption sites on soil particles (Xie et al, 1993). Applications of lime and P fertilizers, therefore, are likely to correct Mo deficiency in soils, provided the soils contain adequate amount of total Mo.…”

“…Applications of lime and P fertilizers, therefore, are likely to correct Mo deficiency in soils, provided the soils contain adequate amount of total Mo. Results so far obtained by various researchers (Burmester et al, 1988;Cox, 1988;Feely, 1990;Khan et al, 1994;Siqua and Hudnall, 1991;Singh et al, 1986;Xie et al, 1993) in this regard are conflicting. The present study was undertaken to investigate the effect of application of lime, P and Mo in all possible combinations on the dry matter yield and Mo nutrition of lentil (Lens esculenta L.) grown in a greenhouse on two acid, alluvial soils.…”

Deficiency of molybdenum (Mo) in acid soils causes poor growth of pulses. An experiment was, therefore, conducted in greenhouse to study the effect of Mo, phosphorus (P), and lime application on the dry matter yield and plant Mo concentration of lentil (Lens esculenta L.) in two Mo-deficient acid alluvial soils. The experiment was conducted using a factorial design with three levels of lime (no lime, half, and full lime requirement), three levels of P (0, 25, and 50 mg kg -1 ), and two levels of Mo (0 and 1.0 mg kg -1 ). Plants were grown for 60 days and at harvest their dry matter yield and Mo concentration were recorded. The three treatments significantly increased dry matter yield, Mo concentration and Mo uptake, the increase being most pronounced with Mo application followed by lime and P. Increases due to applied Mo were greater in presence than in absence of added P; while the reverse was true with the liming treatments. Liming and P application at their lower levels also interacted positively for better Mo nutrition of plants. Results thus indicated that the severity of Mo deficiency in the lentil plants may be reduced by lime and P application in Mo-deficient acid alluvial soils.

“…Also, the local competition for soil sorption sites between nutrients derived from the same co-granulation product ( e.g. , PO 4 and MoO 4 ) could strongly influence the plant availability of the applied Mo. , Finally, regarding the choice of a macronutrient carrier for the Mo-LDH fertilizer, also, the crop requirements should be considered. Therefore, for legume crops, the Mo-LDH fertilizer would ideally not be incorporated in a N carrier ( e.g.…”

is an essential plant micronutrient. Despite low plant Mo requirements, deficiencies are not uncommon and soluble Mo fertilizers are often applied. However, soluble Mo may result in poor Mo use efficiency due to strong sorption (acid weathered soils) or leaching (lighter-textured soils). Here, ZnAl layered double hydroxides (LDHs), loaded with molybdate (MoO 4 ), were examined for their potential as slow-release Mo compounds. Chloride-exchanged LDHs with varying Zn/ Al ratios (2, 3, and 4) were exchanged with MoO 4 . Zn 2 Al LDH indicated MoO 4 intercalation, whereas Zn 3 Al and Zn 4 Al LDHs bound MoO 4 merely on edge sites. Short-term Mo-LDH incubation identified sulfate, carbonate, and phosphate as the most competitive anions for MoO 4 exchange. Long-term Mo-LDH incubation in simulated pH-neutral soil solutions demonstrated slow Mo release from Zn 2 Al LDH (half-life of 35 h), with a total Mo desorption of up to 85%. For Zn 3 Al and Zn 4 Al LDHs, Mo desorption was limited to <20%. Finally, several macronutrient fertilizers were tested as possible carriers for Mo-LDH fertilizer compounds.
