Abstract (sommario):

Zinc (Zn) deficiency is a fairly wide spread agronomic constraint in many of the world rice production regions. Information on soil Zn distribution is essential for understanding its chemical reactions and bioavailability. In this backdrop, we tried to find out the relationship between physic-chemical properties and DTPA-extractable Zn (available Zn) content of rice soils. For this eighty four (84) surface soil samples (0-20cm) were collected from three villages (viz. Saharapali, Nuagarh and Adgaon) of Bargarh district under the Hirakud Command Area of Odisha.

In this paper, zinc flows in arable soils of the Czech Republic and zinc fractions in arable soils are studied. Furthermore, a zinc uptake by agricultural plants is focused. Based on a database of the programme The basal soil monitoring system (BSMS) a static zinc balance for arable soils on the national level was assessed.

Abstract (sommario):

The application of high phosphorus fertilizer by-products to farmland is a common practice used to reduce storage volume and disposal cost. However, because Iowa soils are generally high in both phosphorus and zinc, there are environmental and fertility questions concerning their application to farmland. A greenhouse study was conducted to determine the effect of a soil-applied fertilizer by-product on the zinc-phosphorus relationship in corn and soybean plants grown on three Iowa soil series: Belinda, Downs, and Haig. The soils were mixed with a high-phosphorus fertilizer by-product and plant

Abstract (sommario):

Rice is the major food crop grown on black soils of southern India and these soils have problems of high zinc fixation due to high clay content, high pH and dominance of smectite minerals causing zinc deficiency problems. The addition of zinc fertilizers to these soils has often been ineffective as the element is transformed to unavailable forms particularly under flooded rice conditions. Studies on the distribution of fertilizer zinc among different pools of soil zinc (Viets, 1962) could be useful in formulating methods of zinc application for higher efficiency of utilization.

SUMMARYRice (Oryza sativa L.) is one of the most important cereal crops in the world and a potentially important source of zinc (Zn) in the diet. The improvement of Zn content of rice is a global challenge with implications for both rice production and human health. The objective of the present study was to identify the effects of nitrogen (N) fertilizer rates and Zn application methods on Zn content of rice by evaluating rice production on native soils with different Zn availabilities in 2010/11. The results indicated that Zn application increased rice grain yield and Zn content in grains com

Abstract (sommario):

The article presents the results of the assessment of the distribution of heavy metals content in anthropogenic transformed soils of the industrial zone of Moscow. Excesses of norms are shown, geochemical associations are obtained. The work proved to exceed the maximum permissible concentrations of cadmium, lead, copper, nickel, zinc, arsenic for eleven test sites per 13.95 hectares of industrial zone in 57% of the obtained empirical data on the content of pollutants in the soil. In the investigated area, the contents of lead, copper, nickel and zinc are not uniformly distributed and are withi

Abstract The content of trace elements in soils varies widely and their mobility and availability depends not only on the total content but also on the form of in which these elements occur. The aim of this study was to determine the total content of nickel, lead, zinc and copper in soils used for agriculture, and assess the mobility and phytoavailability of these metals against a background of physical and chemical properties of these soils. In samples taken from three soil profiles (Phaeozem and 2 Fluvisols) the contents of Ni, Pb, Zn and Cu were determined using atomic absorption spectrosco

Abstract (sommario):

This work is devoted to the study of the provision of arable soils with mobile forms of the most important trace elements (cobalt, manganese, and zinc). In modern Russian agriculture, the low provision of soils with trace elements is one of the reasons leading to lower yields and the deteriorating quality of most crops. The materials of the regional and local agroecological monitoring of soils in Belgorod region, which is part of the Central Black Earth region of Russia, were used in this work. The results of the local agroecological monitoring showed that the average gross contents of mangane

Abstract (sommario):

Soil contamination with heavy metals is a global problem, and these metals can reach the food chain through uptake by plants, endangering human health. Among the metal pollutants in soils, zinc (Zn) and lead (Pb) are common co-pollutants from anthropogenic activities. Thus, we sought to define the accumulation of Zn and Pb in agricultural soils and maize. Concentrations of Pb in agricultural soil (in Namibia) could reach 3015 mg/Kg, whereas concentrations of Zn in soil (in China) could reach 1140 mg/Kg. In addition, the maximum concentrations of Zn and Pb were 27,870 and 2020 mg/Kg in maize ro

A greenhouse experiment was conducted at the Indian Institute of Horticultural Research (IIHR), Bangalore to study the interaction effect between phosphorus and zinc on their availability in soil in relation to their contents in stevia (Stevia rebaudiana). The results show that the amount of available P and Zn content in soil has been found to increase initially and, thereafter, the amount of the same decreased with the progress of plant growth up to 60 days irrespective of treatments. The amount of P and Zn in soils showed an increase with their separate applications either as soil or foliar
