ABSTRACT- To evaluate effects of different soil moisture conditions namely, phosphorus (P) and zinc (Zn) application, on extractable Zn and Fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. The first experiment was performed with the following factors; incubation time at four leve...
A field experiment was conducted to evaluate the different brands of zinc fertilizer produced and marketed in different areas of Bangladesh and their effect on nutrients content in rice (BRRI dhan 32). Among the nutrients; the content of N, S and Ca in grains and straw did not vary significantly, but the contents of P, K, Na, Mg, Zn, Cu, Fe and Mn in grain and straw varied significantly due to ...
Organic fertilizers affect soil chemical and physical properties, particularly chemical forms of zinc in soil solid phase and thereby improve soil Zn availability. The present field study was aimed to evaluate the effects of organic and chemical fertilizer (zinc sulfate) on different zinc fractions in soil solid phase of rhizosphere in two successive years in Rudasht Research Field, Isfahan. Tr...
BACKGROUND Rice is the world's most important cereal crop and phosphorus (P) and zinc (Zn) deficiency are major constraints to its production. Where fertilizer is applied to overcome these nutritional constraints it comes at substantial cost to farmers and the efficiency of fertilizer use is low. Breeding crops that are efficient at acquiring P and Zn from native soil reserves or fertilizer sou...
A study was conducted to determine the efficacy of applying ground magnesium limestone (GML) or ground basalt in combination with bio-fertilizer to sustain rice production on an acid sulfate soil in Malaysia. Soils from Kelantan Plains, Malaysia, were treated with GML, ground basalt, bio-fertilizer, GML + bio-fertilizer, and ground basalt + bio-fertilizer (4 t ha 1 each). Results showed that so...
Zinc concentrations in alfalfa hay were varied using a N-Zn liquid fertilizer as a foliar applicant (.34 or .68 kg Zn/ha) or as a soil fertilizer (4.07 kg Zn/ha). Mean concentrations of Zn across five cuttings of alfalfa in 2 yr were 18, 27, 41 and 21 mg Zn/kg DM for control, low foliar, high foliar and soil treatments, respectively. Each treatment was fed in ad libitum amounts to eight crossbr...
In order to study the effects of nano-fertile fertilizer containing humic acid on uptake of nutrients of two lettuce (Lactuca sativa L.) cultivars in a nutrient film technique (NFT) system, a factorial experiment based on completely randomized design with four replications was conducted. The experiment consisted of two factors, the nano-fertile fertilizer (0, 500 and 1000 mg/L) and cultivar (Gr...
Heavy metals in soil, water and air is a great concern. Toxic heavy metals ultimately affect plant, Animals, and through food chain directly influence human life. In present study, the effect of heavy metals (Cu, Zn), Nfertilizers and EDTA on growth and biomass of cannibus sativa plant was evaluated. The Cu and Zn phytoextraction potential of Cannabis sativa plant under various treatments of N-...
Residual effeet of a eoneentrated and depotassitied beet vinasse on growth and mineral eomposition of taH feseue (Festuca arundinacea) was studied. Results were compared with those obtained for a mineral fertilizer treatment and a control. Vinasse and inorganie fertilizer had been previously applied to two different soils at two rates for tive years. High doses of vinasse produeed the highest y...
Fertilizer was applied annually for eight years to individual ramets in a loblolly pine (Pinus taeda L.) seed orchard at rates ranging from 0 to 448 kg nitrogen (N) ha(-1) year(-1). Clonal effects accounted for a major source of variation in both flowering and foliar nutrient concentrations. Foliar N concentrations were generally correlated with the intensity of fertilizer application, but were...
