Excessive uses of fertilizer can create environmental problems such as soil pollution. This problem could be reduced by amending clinoptilolite zeolite with compound fertilizers. The objective of this study was to evaluate the effect of clinoptilolite zeolite rates in compound fertilizers (N: P: K) on maize nutrients uptake and use efficiency. The following treatments were considered and evaluated: soil alone (T1), 44.6 g 5:3:2 formulated fertilizer (12.83 g compound fertilizer + 31.77 g zeolite) (T2), 44.6 g 5:5:5 formulated fertilizer (18.24 g compound fertilizer + 26.36 g zeolite) (T3), 37.17 g 6:6:6 formulated fertilizer (18.25 g compound fertilizer + 18.92 g zeolite) (T4), 22.30 g 10:10:10 formulated fertilizer (18.24 g compound fertilizer + 4.06 g zeolite) (T5), and 14.87 g 15:15:15 commercial fertilizer (T6). Selected soil chemical properties, as well as, dry weight, nutrients concentrations, uptake and use efficiency were measured. Compound fertilizers with zeolite increased soil pH compared to soil alone (T1) and commercial fertilizer (T6). Application of compound fertilizer did no significantly affect total N and available nitrate in the soil. T6 gave better plant height and dry matter production among treatments. Nitrogen concentrations for all plant parts were similar for all treatments. T6 showed better P concentrations, uptake, and use efficiency. K concentrations in maize plant parts were significantly increased for treatments with zeolite except for roots. T5 and T6 significantly increased K uptake. T6 significantly increased N and P uptake and use efficiency, while T2 significantly increased K use efficiency. Amending N, P, and K fertilizers with higher dosage of clinoptilolite zeolite improved soil chemical properties, nutrient uptake of Masmadu variety. Compound fertilizers amended with clinoptilolite zeolite enhanced K use efficiency of Masmadu maize variety.

“…The filtrates were analyzed for K by AAS and UV-spectrometer for P. The concentrations of N, P and K in the plant parts were multiplied by their dry matter to obtain the amount of N, P and K taken up by the plant parts. Nitrogen, P, and K use efficiency were calculated using the subtraction method (Pomares-Gracia and Pratt, 1987). Analysis of variance (ANOVA) was used to test the treatment effects and means of treatments were compared using Tukey's test.…”

Adoption of new management techniques, such as clinoptilolite zeolite (CZ) utilization has attracted much attention in the fertilizer industry. Accordingly, the aims of this study is to evaluate: if CZ, acting as an inert material, when applied to the soil, might improve the selected soil properties, height, dry matter, nutrient concentration, nutrient uptake, nutrient use efficiency on maize cultivation; the potential for (N:P:K) compound fertilizer when incorporated with CZ to serve same standard as the commercial fertilizer in fertilizer industry. The effect of T 1 , T 3 and T 6 on soil total N was found to be significant, when compared with T 7 . Treatments with CZ on soil total P, K and available P, K differed significantly relatively to T 1 and T 7 . The treatments T 5 and T 6 had the highest accumulation of exchangeable NH 4 + and available NO 3 -relatively to T 1 and T 7 . The significant effect of the treatments having CZ on N concentration, in uptake and use efficiency, suggests that CZ incorporated with fertilizer can reduce NH 3 loss, triggering the formation of NH 4 + and NO 3 -over ammonia and increase maize uptake. Relatively to P concentration, uptake and use efficiency, it was found that in most treatments having CZ, lower values were obtained, relatively to the commercial fertilizer, although T 3 clearly improved P uptake in roots. Most of the treatments with CZ remained statistically similar in K concentration, uptake and use efficiency compared to commercial fertilizer. It may be concluded that treatments with higher amounts clinoptilolite zeolite ensured good retention of soil exchangeable cations, available P, and NO 3 -within the soil. Treatments with CZ improved N uptake and use efficiency in the maize crop tested.

“…At Waseca, soil samples were dried after collection, while at Urbana, soil samples were kept frozen until time for analysis, when they were dried (50°C), ground, and analyzed for NO 3 − –N and NH 4 + –N concentration (Mulvaney, 1996). Percent recovery of the applied N was estimated by subtracting TIN in the control plot from that of the treated plots and dividing by the applied N rate (Pomares‐Garcia and Pratt, 1978).…”

Apparent Nitrogen Recovery from Fall‐Applied Ammoniated Phosphates and Ammonium Sulfate Fertilizers

et al. 2010

Phosphorus fertilizer is frequently fall-applied for corn (Zea mays L.). Diammonium-(DAP) or monoammonium-phosphates (MAP) are the preferred P fertilizers and the N in MAP and DAP is assumed to be available for corn. Our objective was to evaluate the eff ect of application time on availability of ammoniated-phosphate N to the crop in two diff erent environments. In a laboratory study, MAP and DAP at rates of 70 and 140 mg N kg −1 soil were incubated at either 80 or 120% fi eld capacity (FC). Nitrifi cation proceeded rapidly in all treatments, but nitrate levels fell to near zero by 8 wk at 120% FC while remaining above 50% aft er 16 wk at 80% FC. In a 3-yr study at Waseca, MN and Urbana, IL with a factorial combination of three N sources [DAP, MAP, ammonium-sulfate (AMS)], two application times (fall, spring), and two N rates (45, 90 kg N ha −1 ), N rate and application time, but not N source, aff ected grain yield and inorganic soil-N concentrations. Yields were 0.71 and 0.37 Mg ha −1 greater for spring than fall applications at Urbana and Waseca, respectively. Late May soil-N recovery ranged from 31 to 35 and 90 to 100% for fall and spring applications, respectively. It thus appears that only about one-third of N applied in the fall as ammoniated phosphates at typical rates is available to the next year's corn crop in Corn Belt mollisols. Colder, drier fall to spring conditions may increase this proportion, while warmer, wetter conditions would be expected to lower availability.
