Research ArticleOpen accessPhrase in the titleThermodynamic Model of Calcium Carbonate System of Soil SolutionAbdulmalik A. Batukaev, Anatoliy P. Endovitsky, Andrey G. Andreev et al.Carbonate system determines the basic processes of soil formation and evolution. The aim of research was to show the importance of chemical Carbonate Calcium Equilibrium (CCE) in soil solutions. CCE causes a degree of soil solution’s saturation with CaCO3 as a factor of carbonate geochemical cycle. CCE depends on chemical composition, pH, Eh, buffering properties of liquid phase, dissolution, migration, … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 18 May 2016 · 7,978 accessesView PDF Cite

Calculation method is proposed for quantitative assessment of real ion forms in the soil solution of chestnut solonetz soil complex. Were proposed … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 24 Jun 2014 · 8,224 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleTHE ASSOCIATION OF IONS IN THE SOIL SOLUTION OF SALINE SOILSA. P. Endovitsky, T. M. Minkina, V. P. Kalinichenko et al.The chemical equilibrium in the soil solution determines the dynamics of its material composition, migration and accumulation of salts. In the soil solution are formed electrically neutral ion pairs CaCO3°; CaSO4°, MgCO3°, MgSO4°, charged ion pairs CaHCO3+, MgHCO3+, NaCO3-, NaSO4-, CaOH+, MgOH+. The calculation method proposed for quantitative assessment of real ion forms in the soil solution of solonetz taking … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 12 Feb 2014 · 8,048 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleAssessment of Soil Solution Chemicals after Tannery Effluents DisposalCélia A. Surita, Thomas Gloaguen, Célia R. Montes, Carlos T.S. DiasKnowledge about soil solution chemicals is important for assessing their mobility, availability, migration to groundwater and toxicity to plants. The objective of this study was to apply factor analysis to data obtained on soil solution chemicals during a one-year monitoring program in a controlled experiment with tannery effluents disposed on the soil surface, to extract information on their relationship and … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,772 accessesView PDF Cite

Review ArticleOpen accessIn the abstractHydroponic Fodder in Broiler Nutrition: Effects on Economics of Production, Environmental Impacts, Productive Indices, and Health StatusChristian Anayo Mbajiorgu, Ifeanyichukwu Princewill Ogbuewu, Monnye MabelebeleThe projected global population of 9.7 billion by 2050 will escalate the demand for animal protein, intensifying food insecurity. Broilers, being highly efficient in converting grains into protein-rich food, are crucial in meeting the ever-increasing demand for animal proteins. However, broiler production, especially in developing countries, is constrained by low quality and unavailability of conventional feed grains utilized in poultry … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 1 · 14 Apr 2026 · 1,694 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Different Functional Microbial Agents on the Biological Characteristics and Rhizosphere Enzyme Activity of Hydroponic CucumberCe Wang, Ouya Zhao, Shiyou Sun et al.This study aims to comprehensively explore the effect of functional microbial agents on healthy soil cultivation and attempt to increase cucumber yield. Three different microbial agents were used for cucumber seedlings by virtue of the hydroponic cultivation method in order to study their effects on enzyme activity and seedling growth and reveal the relationship between rhizosphere enzyme activity and carbon, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 24 Mar 2025 · 5,510 accessesView PDF Cite
