To investigate the relationship between mineral elements and plum gummosis disease, Prunus salicina Lindl. trees with four grades of were used as experimental materials. The contents N, P, K, Ca, Mg, B, Fe, Mn, Zn Cu in branches leaves measured, correlation was systemically analyzed through multiple comparisons, binary logistic regression analysis, ordinal analysis. In addition, effects prevent...

The main objective of this study was to compare the performance of two liquid organic fertilizers, an animal and a plant-based fertilizer, with mineral fertilization on citrus trees. The source of the fertilizer (mineral or organic) had significant effect in the nutritional status of the organic and conventionally managed mandarins. Nutrient uptake, vegetative growth, carbohydrate synthesis and...

The detoxification of crops grown in Cadmium (Cd)-contaminated acid soil has been widely studied, but for contaminated alkaline soil, there is still inadequate research or information. In order to investigate the effects calcium and sulfur fertilizers, accompanied by different side elements, on growth Cd uptake Spinacia oleracea Cd-contaminated plants were subjected five treatments, including s...

Perchlorate consumption can cause mental retardation and tumour formation in humans. Recent suggestions that perchlorate may be present as a contaminant in fertilizers and fertilizer components have caused concern in the fertilizer industry. The present study developed methods for improving the HPLC analysis of perchlorate and used these methods to survey 15 US fertilizers for perchlorate. Extr...

Calcium preharvest application influences fruit quality. The impact of foliar sprays using several commercial fertilizers with Ca content on the quality and nutritional status kiwi cv. ‘Hayward’ was investigated for a 2-year period. Fruit flesh firmness increased under all compared to control. Total soluble solids acidity were not altered significantly by any studied products. Treatment differe...

The present overview is intended to point the readers' attention to the important subject of calcium orthophosphates (CaPO4). This type of materials is of the special significance for the human beings because they represent the inorganic part of major normal (bones, teeth and antlers) and pathological (i.e., those appearing due to various diseases) calcified tissues of mammals. For example, ath...

In China, excessive use of nitrogen fertilizers in glasshouses leads to nitrate accumulations in soil and plants, which then limits productivity. Melatonin, an evolutionarily highly conserved molecule, has a wide range of functions in plants. We analyzed the effects of melatonin pretreatment on the growth, mineral nutrition, and nitrogen metabolism in cucumber (Cucumis sativus L. "Jin You No. 1...

Soil organic carbon (SOC) sequestration is important for improving soil fertility of cropland and for the mitigation of greenhouse gas emissions to the atmosphere. The efficiency of SOC sequestration depends on the quantity and quality of the organic matter, soil type, and climate. Little is known about the SOC sequestration efficiency of organic amendments in Vertisols. Thus, we conducted the ...
