Soil Phosphatase Activity and Phosphorus Content as Influenced by Catch Crops Cultivated as Green Manure
In a 3-year experiment, the effect of catch crop management [catch crop incorporated in autumn (A) or mulched (B) vs plots without a catch crop (C)] on soil acid (PAC) and alkaline (PAL) phosphatase activities as well as on the available phosphorus content (PAVAIL) were investigated on typical Alfisol. The catch crops were sown at the beginning of August and ploughed in the autumn in 2008, 2009...
متن کاملsalinity tolerance of kentucky bluegrass as affected by nitrogen fertilization
in most semiarid and arid areas, fresh water shortage compels managers to use low quality water sources with high salinity to irrigate turf and landscape. recent research has noticed that management of nitrogen fertilization can alleviate salinity effects on plants. this greenhouse sand culture experiment was conducted in order to investigate morphological and physiological responses to salinit...
متن کاملChanges in weed seed banks and the potato yield as affected by different amounts of nitrogen and crop residue
In order to evaluate the impact of crop residues (zero, 25 and 50%) and nitrogen (zero, 125 and 250 kg ha) on weed seed bank and potato yield, two-years research was conducted as a split plot arranged in randomized complete block design in Rozveh Agriculture Research Station, Freidan-Esfahan. Numbers of weed species in seed bank, aboveground, and both seed bank and aboveground were 1, 2 and...
متن کاملInfluence of catch crop on soil properties and yield of spring barley
Biomass of legumes grown as catch crops improves soil properties and thus soil conditions for following crops. The aim of this study was to evaluate the effect of field pea (Pisum sativum L.) grown as a catch crop and used for green manure on soil properties and yielding of spring barley (Hordeum vulgare L.). Field experiments were conducted in 2008-2011 in the randomized block design with ...
متن کاملNitrogen Metabolism in Scenedesmus as Affected by Environmental Changes.
In recent years investigations into the physiology of green algae have been stimulated by a recognition of their possible commercial use (6) in addition to their common acceptance as research tools for certain fundamental problems. These physiological studies have shown that green algae have a high nitrogen content. A correspondingly high protein content has been inferred (28). Relatively littl...
