Abstract:

This study examined the effects of calcium carbonate, calcium oxide and calcium nitrate on the production and accumulation of volatile fatty acids (VFAs) and phenolic compounds (PCs) during soybean residue decomposition. Soil amended with calcium compounds, residue and water was incubated for 7 d at 25 °C. Measurements were made of VFAs, PCs, ammonium-N, nitrate-N and pH in a soil water extract. Accumulations of VFAs were significantly reduced by calcium nitrate amendment whereas both calcium carbonate and calcium oxide increased their accumulation. Accumulation of PCs followed the same trend

Abstract:

Dietary nitrate has been shown to increase cytosolic calcium concentrations within the heart, which would necessitate greater calcium sequestration for relaxation. In the present study we demonstrate that while nitrate supplementation reduced blood pressure, calcium-handling protein content, sarco(endo)plasmic reticulum Ca-ATPase 2a (SERCA) enzymatic properties, and left ventricular function were not altered. In addition, nitrite did not alter in vitro SERCA activity. Combined, these data suggest that in healthy rats, dietary nitrate does not increase left ventricle SERCA-related calcium-handl

In terms of the thermal features of the tested energetic materials, a similar and significant influence of the auxiliary oxidising agent and sensitising agent choice was observed.

Recently, there has been increased use of calcium-nitrite and calcium-nitrate as the main components of chloride- and alkali-free anti-freezing agents to promote concrete hydration in cold weather concreting. As the amount of nitrite/nitrate-based accelerators increases, the hydration of tricalcium aluminate (C3A phase) and tricalcium silicate (C3S phase) in cement is accelerated, thereby improving the early strength of cement and effectively preventing initial frost damage. Nitrite/nitrate-based accelerators are used in larger amounts than usual in low temperature areas below −10 °C. However,

However, excessive nitrate in the environment and watershed has harmful impacts on natural ecosystems and consequently human health.

The disadvantage of calcium peroxide was that pH (8.6) would rise slightly and accelerate NH3-N release. Spraying poly-aluminum chloride also could prohibit phosphorus release from sediment.

Abstract:

The availability of chill hours influences the break dormancy, sprouting and production of temperate fruit trees in different regions. During the winter, the chilling requirements for growing peaches in subtropical locations are restricted, and certain chemicals are required to overcome dormancy and induce budburst. As a result, further information concerning the use of these compounds on stimulating sprouting in peach trees is required. The purpose of this study was to evaluate the ability of hydrogen cyanamide, nitrogen fertilizer, and calcium nitrate to trigger budburst in the ‘Douradão’ pe

Abstract:

The current climate trends and the reduced impact of biostimulants on the environment, agriculture and horticulture have increasingly oriented towards the use of biostimulants as part of the technologies applied to plants. This present study investigates the effects of different foliar treatments with calcium nitrate, used with or without biostimulants, on the yield and quality of round pepper fruits, Asteroid 204 cultivar, in order to use them in the culture technology of this species. Starting with the fruit set, four foliar treatments were applied in the field with an interval of 10 days be

Nitrate pollution of groundwater has been increasing in recent years. The aim of this work was to study the morphological features of the bone marrow of rats at the consumption of drinking water with varying nitrate content. The experiment was performed on 2 groups of white female rats of different ages (mature and immature) with 30 individuals each. Both groups were divided into 5 subgroups that differed in the quality of drinking water consumed by rats on their own. In the 30 days study, nitrate was given to rats in drinking water in doses of 50, 150, 250, 500 mg of sodium nitrate per liter.

The effects of fertilizer applications at rates from 0 to 150 kg N ha-1 and the timing of application were studied, using three fertilizer forms: calcium nitrate, ammonium sulphate and ammonium nitrate. Calcium nitrate applications significantly increased grain N concentrations (P < 0·05), and grain yields (P < 0·01 and 0·05) at two sites, above the values obtained with the

Agronomic practices in Indonesia mostly still use ammonium as the primary source of nitrogen (N), whereas ammonium concentrations at certain levels can cause plant toxicity. The selection of the suitable N form (NH4+ and NO3-), especially by the fertigation method, is expected to increase the efficiency of N fertilization. This research aimed to obtain the appropriate source of NH4+ and NO3- to increase production and efficiency of fertilization in shallots.

The amount of mineral nitrogen in the soil profile 4 weeks after seeding increased with the addition of each of the sources except for the 1% nitrogen organic material which had no effect.

However, slightly higher molar absorption coefficients of the metal cations in the molten solutions than those of the aqueous solutions suggested the possibility of mixed coordination by both aqua and nitrato groups.
