Urethanes and Soil Nitrification
Urethanes have marked physiological activity in plants and animals. Lefevre (1939) found that phenyl urethane affects wheat germination, and subsequently Templeman and Sexton (1946) showed that a variety of urethanes suppress the germination of wheat and oats without affecting charlock. The most active urethanes (for example, isopropylphenylcarbamate;ethylphenylcarbamate) are effective at a con...

متن کاملAdaptation of soil biological nitrification to heavy metals.
The adaptive response of soil biological nitrification to Zn and Pb was assessed using an in situ method we have developed. The method is based on reinoculating a sterilized metal contaminated soil with the same soil that is either uncontaminated or has been incubated with metal. This approach excludes the potentially confounding effects of metal aging reactions in soils. We found added Zn conc...

Soil temperature at the time of application has been the primary It has been recommended that fall applications of N factor used to predict rates of nitrification and assess the risks associbe delayed until soil temperature has decreased to 10 C ated with losses of N applied in the fall as anhydrous ammonia in the at a depth o...
متن کاملBiochar increases soil N2O emissions produced by nitrification-mediated pathways
*Correspondence: María L. Cayuela, CEBAS-CSIC, Campus Universitario de Espinardo, 30100 Murcia, Spain e-mail: [email protected] In spite of the numerous studies reporting a decrease in soil nitrous oxide (N2O) emissions after biochar amendment, there is still a lack of understanding of the processes involved. Hence the subject remains controversial, with a number of studies showing no cha...
