the effect of european black alder (alnus glutinosa l.) on the contents of carbon and nitrogen,exchangeable base cations, and plant available forms of phosphorus in the reclaimed mine soils formed bywaste deposition from opencast lignite mines was researched in central serbia. it was concluded that thegreatest part of dead organic residues reaching the soil under european black alder monocultur...

under favorable soil conditions such as existence of easily destructible organic compounds, balanced heat and moisture, adequate ventilation and abundant nutrients, organic materials are mineralized. once mineralizing occurs, mineral elements like p, s, ca, mg, k and other cations are released. a related study was conducted to determine the effect of seven organic fertilizers (leaf mold (lm), r...

Soy sauce with a high salt liquid-state fermentation process was prepared by using organic soy beans as raw material. Beidahuang organic soy bean was selected among different raw materials. Here, the best technique was determined. Firstly, the organic soy beans were soaked for 7 hours under 121°C , steamed for 15 min and mixed with the fried wheat (5:5, w/w). After inoculated with Aspergillus o...

The study on soil spectral reflectance features is the physical basis for soil remote sensing. Soil organic matter content influences the soil spectral reflectance dramatically. This paper studied the spectral curves between 400nm~2500nm of 174 soil samples which were collected in Hengshan county and Yixing county. Fourteen types of transformation were applied to the soil reflectance R to remov...

Salt-impacted soils occur in floodplains, wetlands and backswamps in arid climates. These soils become sinks or temporary storage sites for soluble salts and contaminants including agricultural chemicals, industrial pollutants and radionuclides such as I. The vertical distribution of I in the Black Butte soil series along the Virgin river was assessed and the distribution of I between I , IO 3 ...

A study was conducted to investigate the effects of feeding inorganic or organic Zn and Cu on the performance and tissue mineral content of chicks. A corn-soybean meal diet without Cu and Zn supplementation, containing 31 mg of Zn/kg of diet and 6.6 mg of Cu/kg of diet, was used as a basal diet. Organic Zn (a chelated Zn proteinate) and organic Cu (a chelated Cu proteinate) were used as organic...
