A field study with spring barley (Hordeum vulgare L.) was conducted on the area of long-term balance experiment in Tsalapitsa village near Plovdiv (Bulgaria), alluvial-meadow soil. Mineral fertilization not applied to this crop order equalize regarding nutrient content. The grown before maize 4 variants and one control variant: N0P0, N100Р50, N150Р100, N200Р150, N250P200. present aimed evaluate...

The balance of the mineral nutrition in mango leaves during flowering period affects trees and fruit production. Because soil karst areas has a slow unbalanced supply rate nutrients, orchards area generally have low yield. There are few studies on fertilization areas, especially diagnosis leaf nutrition. In this study, typical Guangxi province, one main mango-producing China, were selected from...

ABSTRACT In the Brazilian Savanna, most of soils have a low natural fertility. order to overcome this limitation, farmers use large amounts soluble fertilizers, causing environmental impacts. present study, finely ground biotite syenite (0; 600; 1,200; 1,800; and 2,400 kg ha-1) was evaluated as an alternative source nutrients electrical charges in weathered Ferralsol from Savanna. Additionally,...

Recent studies demonstrated a significant impact of some major macronutrients on function and production medical cannabis plants, yet information the effect most nutrients, including Mg, is scarce. Magnesium required for physiological functions metabolic processes in present study we studied effects five Mg treatments (2, 20, 35, 70, 140 mg L−1 Mg), plant development function, distribution mine...

Edible nuts have an increasing role in human diet. Pistachio is popular but less known kind of edible nut nevertheless it is rich in health benefiting nutrients, minerals, antioxidants and vitamins. This research focused on the concentration of nitrogen (N), phosphorus (P), potassium (K) and calcium (Ca), all of which play a key role in the healthy human nutrition and lifestyle in the kernels o...

Cross-linked polymer hydrogels, polyacrylamide co-polymer (XPAM) or polyacrylate (XPAA) offer potential solutions for soil degradation, declines in resilience, and poor productivity marginal soils. However, little is known about their long-term effect on nutrient availability. This 9-yr, irrigated, outdoor, cropped pot study evaluated a single, one-time addition of XPAM XPAA at 0.25 0.5% dry wt...

Rubber cultivation is primarily rainfed agriculture, which means that water supplies are not stable in most rubber cultivated areas. Therefore, improving the use of trees through fertilization management seems to be a breakthrough for enhancing growth and latex yield carrying out intensive agriculture. However, relationships among nutrient status trees, their uptake, soil resources, including n...

Introduction: To assess the salivary composition of proteins and minerals in smokers compared with non-smokers.   Materials and Methods: In this study we compared the total protein and Ca, Na, K, Mg, Pb of whole saliva in two groups of men (28 smokers and 31nonsmokers) aged between 29-41years.   Results: Fifty-nine participants were evaluated. The mean age was 33.14±5.32 years among smo...
